New:
Hi guys. First I want to thank you all, both current and former users, for being here in this thread with me. It's been a pleasure for me, you are all awesome.
This release is the final update of Spring. It'd took a bit longer as I wanted this one to be the most throughout tested release to date. It's rock stable for me, probably the best rom version I've released.
Now I'm moving to another project, which is different to this project, and it feels super exciting. So I'll hope to see you around.
Thanks again,
Per
Rom no longer forces encryption, meaning there's no need to flash a different kernel to stay decrypted.
The main goal with this project is to provide an optimized ROM with a handful of useful features added, on top of a heavily improved base (kernel) to improve speed, network and battery life.
This is my personal preference of how a ROM should be. I will never add features just for the sake of it, I pick those which makes sense for me. This is a one man ROM, which is good as I got control over every little bit of the process. The base of Spring is CyanogenMod 12.1 and I will always try to keep this as close to CM as possible, but at the same time improve the experience for me and you.
Except for the great features CM provides, the following additions are made (changelog in second post):
Rom additions:
Disabled forced encryption
- Added a quick setting tile to toggle expanded desktop.
- Built with latest 4.9 linaro
- Patches and optimizations from linaro.
- Added a setting to force expanded notifications (Settings -> Notification drawer -> Force expanded notification). This feature is nice when you have a big device as ours. Credits to jmztaylor.
- Settings: addded development animation transition mode 0.9. I find 0.75 too fast, and some stutter may occur. 0.9 makes no sacrifice of the lollipop fluidity and speeds the animations up 10%.
- Added LCD Density changer. Credits to Tom Marshall (Source 1) (Source 2). I very much recommend to set the DPI to 480. This will give you more screen real estate and improve your android experience. Try it, play around, and evaluate after a couple of days.
- Fixed some graphics to go with a wider range of densities.

Kernel additions:
- M-Preview kernel.
- Kernel compressed with LZ4 (see https://lwn.net/Articles/534168/ for info).
- Optimized VMA caching (see this for info)
- Byte-sized index for the freelist of a slab (see this for reference).
- Updated idle driver and suspend (deep sleep) code.
- MSG_FASTOPEN is now enabled by default. You can try it in your chrome browser. Enable the "TCP Fast Open" flag.
TCP Fast Open is an optimization to the process of stablishing a TCP connection that allows the elimination of one round time trip from certain kinds of TCP conversation, which can improve the load speed of web pages. In Linux 3.6 and Linux 3.7, support was added for this feature, which requires userspace support. This release enables TCP Fast Open by default.

- TCP auto corking.
When applications do consecutive small write()/sendmsg() system calls, the Linux kernel will try to coalesce these small writes as much as possible, to lower total amount of sent packets - this feature is called "automatic corking". Automatic corking is done if at least one prior packet for the flow is waiting in Qdisc queues or device transmit queue. Applications can still use TCP_CORK for optimal behavior when they know how/when to uncork their sockets. A new sysctl (/proc/sys/net/ipv4/tcp_autocorking) has been added to control this feature, which defaults to enabled. For benchmarks and more details see the commit link. For benchmarks see this commit.

- Multiboot compatible.
- Completely ditched the interactive governor from 3.10 kernel and replaced it with the one from the 3.18 kernel.
- Added a quickwake patch from Motorola.
The purpose of this feature is to drastically reduce the suspend/resume time for device driver which needs to do periodic job. In our use case (android smartphone), the system is most of the time in suspend to RAM, and needs to send a low level command every 30s. With current framework it takes about 500ms on omap3430 to resume the full system, and then suspend again. With quickwakup feature, in the resume process after resuming sysdev and re-enabling irq, the driver handler is executed, and then it suspends again. This new path takes 20ms for us, which leads to good power-saving.

- Added SCHED_DEADLINE, a new scheduling class for resource-reservation real-time CPU scheduler in the kernel.
Quoted from: https://lwn.net/Articles/575497/: "Deadline scheduling does away with the concept of process priorities that has been at the core of most CPU scheduler algorithms. Instead, each process provides three parameters to the scheduler: a "worst-case execution time" describing a maximum amount of CPU time needed to accomplish its task, a period describing how often the task must be performed, and a deadline specifying when the task must first be completed. The actual scheduling algorithm is then relatively simple: the task whose deadline is closest runs first. If the scheduler takes care to not allow the creation of deadline tasks when the sum of the worst-case execution times would exceed the amount of available CPU time, it can guarantee that every task will be able to finish by its deadline. Deadline scheduling is thus useful for realtime tasks, where completion by a deadline is a key requirement. It is also applicable to periodic tasks like streaming media processing."

- Added Heavy-Hitter Filter (HHF) qdisc.
This is a first size-based qdisc that attempts to differentiate between small flows and heavy-hitters. The goal is to catch the heavy-hitters and move them to a separate queue with less priority so that bulk traffic does not affect the latency of critical traffic. Currently "less priority" means less weight (2:1 in particular) in a Weighted Deficit Round Robin (WDRR) scheduler. In essence, this patch addresses the "delay-bloat" problem due to bloated buffers. In some systems, large queues may be necessary for obtaining CPU efficiency, or due to the presence of unresponsive traffic like UDP, or just a large number of connections with each having a small amount of outstanding traffic. In these circumstances, HHF aims to reduce the HoL blocking for latency sensitive traffic, while not impacting the queues built up by bulk traffic.

- Added PIE AQM scheme
This is a Proportional Integral controller Enhanced (PIE) scheduler to address the bufferbloat problem. Bufferbloat is a phenomenon where excess buffers in the network cause high latency and jitter. As more and more interactive applications (e.g. voice over IP, real time video streaming and financial transactions) run in the Internet, high latency and jitter degrade application performance. There is a pressing need to design intelligent queue management schemes that can control latency and jitter; and hence provide desirable quality of service to users. We present here a lightweight design, PIE(Proportional Integral controller Enhanced) that can effectively control the average queueing latency to a target value. Simulation results, theoretical analysis and Linux testbed results have shown that PIE can ensure low latency and achieve high link utilization under various congestion situations.

- Many updates to the interactive cpu governor.
What is an interactive CPU governor? Quoted from https://android.googlesource.com/ke...aebe08b/Documentation/cpu-freq/governors.txt: "The CPUfreq governor "interactive" is designed for latency-sensitive,interactive workloads. This governor sets the CPU speed depending onusage, similar to "ondemand" and "conservative" governors. However,the governor is more aggressive about scaling the CPU speed up inresponse to CPU-intensive activity."

- Many updates to cpuidle.
What is cpuidle? Quoted from www.fsl.cs.stonybrook.edu/docs/cpuidle/cpuidle-from-userspace.pdf: Cpuidle is a module in the Linux kernel which is respon- sible for running some power saving routines on a core when the core does not have any task in its run queue . The power saving routines try to put the core into a low power state or an idle state."

- Added frandom module. The following is quoted from Eli Billauer at (source):
Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.

2015-09-22
- Kernel update to 3.10.89.
- Updates to wireless driver.
- Upstream updates.
2015-09-16
This update is all about power saving behavior. I don't like the stock behavior, it throttles the CPU as soon as you hit 40% and unplug a CPU as soon as you hit 15%. As long as we have the battery saver feature and the fast charging, let us stay in control, and don't force a worst performance on us. I've changed it so the CPU will throttle at 20% and unplug a CPU at 10% (and never unplug a second one).
I've also enabled a low memory kill optimization option, to have LMK select task to kill from rbtree.

- A few optimizations from the Android M-release.
CM upstream with the following changes to WiFi-calling and Enhanced 4G LTE Mode:
- IMSEnabler: Application to toggle the Enhanced 4G LTE Mode setting
Somewhere in the changes made by caf to IMS the AOSP ims.apk is not
reading that Enhanced 4G LTE Mode is enabled at boot, or possibly its
a race condition. IMS works fine if it is toggled off and back on
after network data is established. So we set up a reciever for network
change events and do the toggle when mobile data is activated.

KERNEL
- Memory enhancements.
- Updated CPU interactive governor to follow aosp-common/android-3.18 repo.
- CM upstream with a big update to the f2fs file system.
2015-05-31
- Android M kernel base. Kernel is now up to par with the kernel coming with Android M. I've redone my whole kernel (again lol) so every single commit from Android M preview is implemented cleanly without a single conflict. I've implemented all my improvements, and CM improvements, from the past on top of the Android M kernel, thus you don't miss out on the features from past releases. Also, the kernel base is updated to 3.10.79 so it's on par with Linux mainstream. This means it's up to date with both AOSP and Linux and in whole provides a cutting edge kernel.
- ROM-wise there's a lot of updates to AOSP repositories.
- CM upstream
- VoLTE now kind of works. It will soon fully work but in the meantime see this post: http://forum.xda-developers.com/showpost.php?p=61028937&postcount=76

New: It's time for an update, and this time I'm bringing you something special. I've never been satisfied about how the CPU behaves on the interactive governor, the scaling behavior and jumping between cores and frequencies sometimes doesn't seem logical. After monitoring the CPU in different situations, especially when idling, made me want to improve the governor.
So, in today's release the interactive governor from 3.10 kernel is ditched completely. Rm'd.
Instead you'll find a completely updated interactive governor, implemented straight from the 3.18 kernel. This version of the interactive governor is implemented in a much cleaner way. It's more simple, more clean, and the the result is satisfying to say the least.
I've been running this one for 24 hours now. The way it deep sleeps, the way it idles and the way it scales up under heavy load seems great. So it should be more gentle to your battery and suite you well when you need to do some heavy work.
On a last note. This wasn't complicated. Sometimes you miss the most obvious things and opportunities, which are right there in front of you to grab.
Enjoy folks,
Per

The no encryption kernel is also updated.
2015-04-20
- You'll find a flashable kernel zip here with forced encryption disabled. If you are decrypted, flash it after you flash my ROM (before booting) and you'll stay decrypted. The ROM itself still forces encryption so flash this zip if you want to stay decrypted.

Super excited to try this! Flashing now. OP sounds very thorough. Love the idea of simple and stable.
Cool to see another BFS adopter
Double-tap to wake working nicely. Returned DPI to default (560), but Appstore still doesn't recognize it as a Nexus 6. I can download "Amazon for Tablets", but not the regular Amazon app.
Good job. This ROM flies.. Optimizations make a huge difference.
How do I change DPI back to the 560 I can't download anything from play store.

You can't even get TexDroider from the store? If not.. Google search it and you'll find the apk.
Or you can edit the build prop back to 560 or whatever you like with Root Browser / Editor.
Sounds cool. Wish it was earlier. Be back to try this tomorrow. Thanks

About DPI and Play Store: The density of your rom, like 480, will be registered within Google apps. If you change the density it needs to get re-registered. You could let it sit for a while or try to clear Googla Play Services, Google Services Framework and Play Store cache followed by a reboot. You would probably have to wait some time after this for the new density to get registered.
The reason I changed the density within the source is that if you do a clean install (format system and data before flashing) the only density which will be registered to Google apps upon first boot is 480 and you will have no problem installing apps in Play Store. I've installed 100+ apps without no issues whatsoever when following those instructions.
480 is the "native" density for Shamu and it was actually used by google some time before releasing. It gives you more screen real estate and I highly recommend using it and take advantage of the big beautiful screen we have.
Some odd apps, like Amazon app store, chooses the tablet layout resources when on 480 DPI. Not many apps behaves like this and it's not that big of a drawback IMHO. If you feel it is you can always sideload the Amazon app store phone layout app using http://apps.evozi.com/apk-downloader/. Don't use that link to try and download paid apps (It won't even work).
Thanks...I was indeed referring to downloading the Amazon Store app from Google Play.
Nice and smooth so far ! Thanks for sharing !
Rom updated to 20150409, changelog in second post.
Cheers,
Per
Solid ROM, very fluid. Just wish you had, or plan to add, LCD Density. :good:

Sorry for that mate but I haven't said I've disabled encryption by default. This is based on CM kernel and CM kernel is encrypted by default. You can't assume a non default feature is there if not stated by me.
I guess you can back up your data, flash a kernel with default encryption disabled, wipe userdata with fastboot and restore your data.
Can I ask why you want it decrypted? I can't find a good reason
Kirisakura-Kernel for HTC U12+
Hello everyone,
Kirisakura kernel is designed to bring a handful of beneficial features to the device, while ensuring excellent performance and smoothness to get you safely through the day!
This includes upstreaming to latest linux stable for enhanced security and stability. As well as bringing in important new CAF patches, as soon as CAF releases the sources for the SD 845!
Revisiting the stock EAS implementation for further efficiency enhancements is also on my current roadmap for future development. I´m sure there is potential!
To have a read about our scheduler, which is called EAS, take a look here:
https://developer.arm.com/open-source/energy-aware-scheduling
Main Features:
- Based on latest kernel sources from HTC for the HTC U12+ (2.45)
- Upstreamed to latest 4.9.246

How to set up the kernel
as with release 4.1.1 it’s advised to change no boost settings at all! It’s all flash and forget
This is a short guide on how to set up the kernel. This is currently required because TWRP is not yet ready and therefore I have no ak2 zip to set that all up.
The following is deprecated as with 0.5 Release!
Basically I decided to disable pnpmgr. This is htc’s daemon for controlling the CPU boosts.
I integrated a few other boosts to the kernel that work way better to replace HTC´s mechanism.
The phone is more smooth and more efficient now.
This is not a requirement at all. It´s entirely optional in case you aren´t satisfied with the current state of things!
1. With a root explorer go to /system/vendor/etc and rename pnp.xml to pnp.xml.bak
That will disable pnpmgr on the next reboot.
2. In EXKM navigate to CPU -> Boost Settings
3. Set the values like on the attached screenshot! and toogle the arrows to set it on reboot
4. cpu input boost currently has no interface in EXKM. The predefined values are fine. But if you navigate to Tools -> User Settings, you can call any file and change the values exactly to your liking.
Just hit the + and add the following paths:
sys/module/cpu_input_boost/parameters/input_boost_freq_lp boost freq of the little cluster
sys/module/cpu_input_boost/parameters/input_boost_freq_hp boost freq of the big cluster
sys/module/cpu_input_boost/parameters/input_boost_duration boost freq duration
5. Reboot and profit
The following is advised as with the Release of 0.5!
1. If you previously renamed pnp.xml found in /system/vendor/etc, to pnp.xml.bak, rename it back to pnp.xml!
Now reboot!
2. Here is a screenshot of the optional boost settings I´m currently running. These are a bit more aggressive than stock, provide more smoothness but cost a tiny bit of battery. In the end I still achieve way better battery results on 0.5 than on 0.2 even with additional boosts enabled. That is due to the energy saving commits I mentioned in the changelog of 0.5.
Here is the screenshot!

You can control kcal with exkm app.
But you can just control srg, saturation, contrast etc.
With Kcal nothing can be done about the brightness. Sorry for that!
I forgot to add Wireguard as a supported feature. I corrected this in the OP.

There is absolutely nothing wrong with the brightest on this phone. Slightly dimmer than U11. Currently have auto brightness off and set just under half way. In the sun it visible at 3/4 brightness.

No Gravity Kernel 1.0.0 + 4.3 App Trailer
Hey, NoGravity Kernel dev coming from the good old OnePlus 2 here! I'm a graduating student in computer science and I actually work as a programmer. I made a pretty solid kernel for that old Oneplus device and even added Energy Aware Scheduling (EAS) support to it backporting new features like Dynamic Schedtune Boosting to this old 3.10 kernel. With it being pretty much at its apogee, I need a new challenge on a newer kernel (4.9+) while keeping NGK's mindset of Performance/smoothness while getting decent battery life due to added battery oriented features.
For those who want a to know more about my work here is the link to NoGravity Kernel for OnePlus 2.
The Kernel will boot using stock (Pocophone F1) CPU & GPU frequencies that correspond to the Balance Profile when Magisk is present. Overclocked frequencies can be selected in any kernel manager app. Other profiles for battery, performance and gaming can be switched to in my app.
To tweak the kernel easily, here's my No Gravity app! featuring custom profiles (Battery, Balanced, Performance and Gaming). My app offers some features that cant be found in other kernel tweaking apps. You can find them lower in the thread.)

This kernel should work on any ROM/Ports! Since I love OnePlus and I'm myself a OnePlus 2 user, I will do my best to fully support OOS ports.
Reported to work on: OnePlus 6 Holi Edition, OnePlus 7 OB8 & OB8 Quince, Quarantine Edition. OxygenOS devs do not support custom kernels so if you face any issues with NGK don't post in their groups, post here instead. Latest OOS may have calling issues as reported by some users.
-I recommend before coming to conclusion, give it at least 2 complete charge cycles and then raise any issue.
-I recommend to use my app, franco app or EX Kernel Manager if you need to tweak the kernel further
-CPUs since Snapdragon 845 can't be overclocked from kernel this is why it is removed
-Flash No_Gravity_Kernel-vX.X.zip file in TWRP (Latest TWRP Recovery Recommanded)
-(Optional) - Clear cache and Dalvik => if you do so, Use App Optimization button in NGK App.

Notes:
Max GPU frequency of 835MHz is only reachable manually as I don't consider it fully stable. On the other side, 820MHz Overclock is stable and is used in my profiles.
I wanted to use relatively longer dynamic schedtune boost duration compared to input boosts so made them separate in terms of length.
I would recommend turning off No Gravity app toast notifications from Magisk Manager app.

And many more under the hood changes...
Notes:
Thermal Suspend API : This is a small API I’ve written in the kernel directly (to make sure no background services are running for it) that unsets NGK thermals when screen turns off and enables them back when screen is turned back on. (This fixes some issues on some specific ROMs where screen wouldn’t turn on or phone would random reboot while device sleeps or is charging)
There is now a camera fix version to fix camera on ROMs with Q-Blobs like MIUI Q, so if your camera isn't working flash this one.
Kernel 1.1 Pie Edition:
NoGravity Kernel v1.1 now working on Pie ROMs
Using v1.0 Base
Notes:
This kernel uses v1.0 base so will work on both Android Pie and Q ROMs/Ports/MIUI
From now on releases will be separate in 2 builds: [9] and [10]. People on Android 10 should use [10] builds since it is rebased to Full Q CAF sources even tho [9] build would still work.
1.1 Build: Welcome to No Gravity Kernel App for Pocophone!
NoGravity Kernel App v3.1:
Pocophone F1 support added
Balance(Default),Performance,Battery & Gaming Profiles*
Precise CPU temperature for both Clusters separately
Kernel 1.1:
Rebased completely to full Q CAF (LineageOS Staging)
Removed CPU overclock*
Removed charging throttling*
Many Optimisations
F2FS updated with GC and changes
Debloated the Kernel
Westwood(Default) & BBR TCP Algorithms added
Using 2048kb read ahead
Fixed ZEN I/O Scheduler initialisation
Picked port of RCU's taken from 4.14
Updated SDFAT to EXFAT
Removed a CPU boosting driver that could conflict with another
Battery oriented tweaks
Tried to fix random reboots and other issues some people were getting
Always upstreamed to latest! (4.9.206)
And many more under the hood changes...
Notes:
Profiles also have a QSTile for fast switching
If you didn’t already know it was only placebo/performance wouldn’t change, but don’t worry there are other ways to make performance better
If you want charging throttling, you can set it back on here by setting the value to N instead of Y: sys/modules//sys/module/smb_lib/parameters/skip_thermal
MIUI ROM/Port variants may have some issues but I didn't have much testers on those so please send logs if you have issues
1.0 Build: Welcome to Android 10 & Pocophone!
Kernel:
Overclocked CPU (Silver 1.76->2.0Ghz, Gold 2.8-> 3.0Ghz) (Will boot with stock clocks)
Energy model modifications to fit NGK overclocked frequencies

Useful stuffs
Clean flashing a kernel:
1. Boot into recovery
2. Wipe dalvik/art cache, cache, system and vendor(if recovery have this option)
3. Reboot into recovery (only needed on some recoveries)
4. Flash latest ROM zip
(Optional) Flash other zips like GApps, DFE, etc depending on ROM and your preference
5. Flash latest Magisk zip
6. Reboot into system (yes boot with stock kernel first)
7. Reboot into recovery
8. Flash latest NGK Kernel zip
9. Reboot and enjoy
Not to be confused with a ROM clean flash!
Do not wipe data or internal storage!
Encryption fix
For the ones who uses an encrypted device, those steps needs to be done to worl properly with NGK:
To those who are facing screen flicker/bootloop upon flashing NGK on an encrypted device.
1. Dirty flash your current ROM and boot into system.
2. change your password to whatever you want then click on "No" when it shows "Secure Start-up".
3. Boot into recovery then flash NGK. You will notice that it will not ask for a password even though you are encrypted.
Taking logs
Screen Freezes:
-Connect phone to PC
-Run following commands in terminal:
[*]adb shell
[*]dmesg
Random Reboots:
-When the random reboot occurs press the TWRP button combo to got straight into TWRP
-Send the pstore folder as a .zip file located in /sys/fs/
Any runtime kernel/app related crashes that doesnt make the device reboot or freeze:
-Use Matlog app on play store
-Start recording before the issue
-Stop recording after the issue
-Send the .zip file created
Charging:
Okay lets break it down for yall.
Every kernel on every device has WARM_TEMP and HOT_TEMP values which are usually always 45 and 50 respectively.
When device reaches 40-42C charging rate will decrease more and more until it reaches about 45C where device will stop charging even if its plugged in for safety reasons. Battery must not charge when they are this hot.
Battery thermal removal: this will prevent throttling before battery reaches about WARM_TEMP. Once battery reaches about 45C there is nothing in the world you can do. So yea battery thermal removal is still safe, just a matter of preference because if charging throttles before reaching 45C it will heat less then continue charging but if charging doesnt throttle yea it will charge charge faster under 45C but may heat more so you may hit 45C faster. So as in every other tweaks it depends on user.
As per my tests I would get about those but that may vary for you:
Battery temp (°C) - Charging rate (mA) tuples
46-1800
45-1800
44-2000
43-2600
42-2800
What else? oh yea here are some tips for you to lower temps (cause yes some of you charge while playing pubg..)
Tips for lowering temps:
-Turn off NGK thermals from NGK APP
Right you all need to understand thermals first.. A lot of users are just asking best thermals, best this, best that.. there is no universal bests..
Thermals will throttle performance depending on heat generated.. so yes there is a gain in performance when using NGK thermals because performance will throttle at higher temperatures. Why do I say it depends? Well someone living in a hot place and is getting high temps and throttling will use NGK thermals so he gets more performance for the same temperature point but there is always throttling else a phone would heat too much in the end and be really unsecure and all. That being said, if your device throttle with stock thermals then you go ngk thermals it will throttle at higher temps but in the end may still throttle and if you hit too high temps it will throttle even harder to keep temps low. For those people using normal thermals would be best since yea performance will throttle but it will prevent the phone from getting higher temps which could lead to more intense throttling. (Can also read about charging above you may want more aggressive thermals that will throttling performance to reduce heat so you can charge phone)
So next tip:
-Reduce Big cluster max frequency as this cluster is a hest generator
-Use another profile than Gaming! (Performance for me is best because its less aggressive, some people prefer balance for gaming)
All in all, try stuffs by yourself I think I did my part guiding you through all this, the best things you can do is the best things for yourself not necessarily the best for others.
Touchscreen Tests (NGK v1.5.5):
Spent a whole week with testers to just sit down and find the firmware to choose and then rebuild the drivers from the groud up.. but first here's an intro
Intro:
Small intro for everyone cause many people confuse many things..
-Panels: We have 3 main panels:
FTS, NVT REV1 & NVT REV2
-Touch firmware: comes in kernel and also in ROMs but kernel will flash its inbuilt firmware if the kernel firmware checksum is different to the one already present in ROM
-Touch Drivers: comes in kernel and those dont have numbers/versions its up to the kernel dev to make changes it those so stop asking for driver version no one can answer that precisely compared to firmware
Tests:
Alright now enough talking, the tests and results.
-Panels:
For FTS panels, using stock xiaomi drivers was fine no touch issues seem to happen since those went out.
For NVT panels, some had touch issues on rev1 and rev2 depending on firmware used while keeping xiaomi stock drivers so below tests were focusing on NVT mostly
-Firmware:
We tried 3 firmware and the ones who remained are 9.1.24 and 10.3.7 since other one gave issues
So I did incremental test builds modifying drivers for both firmware
-Drivers:
For drivers, as said before I reverted all changes to xiaomi stock drivers from their source. Some issues were present for some on both firmware version and different issues on both panel revisions (rev1 and rev2)
-Latency:
some issues was only related to latency and I knew latency was going to be better by optimizing the drivers later on
-Touch issues:
So based on that, I only took account of the issues present between firmware for each driver changes
Part 1:
Part 1 was updating novatech drivers from a CAF source that can be seen in my kernel source. So did that, compiled 2 versions again fixed some small issues here and there like firmware flashing wasnt working, touch didn't work at first and some bootup issues, anyway main thing is that novatech driver were updated a bit with less variable locking and such coding changes making the driver faster. Results after that were good it fixed some people's issues but latency wasnt perfect.
-Part2:
Now was time to optimize the drivers and did for both NVT and FTS (most of those optimizations were seen in previous ngk versions) but needed to add them again and add some more and see how they impact (cause not every optimizations means better results, some optimizations introduced issues)
Conclusion:
So in the end if TLDR
The conclusion was that issues were fixed after some driver changes as some optimizations made them worst, 9.1.24 firmware gave better touch (mostly under load or heat a.k.a for gamers) and didnt impact day to day users hence why NGK uses now 9.1.24 drivers.
BUT that is based on the fact that I reviewed the drivers from official xiaomi source, then updating them, then doing specific optimizations, other kernels may have different results or different ways of doing tests, thats just how I did it.
So yea for people who wont like touch, I will send this cause I did work on it to give better touch to most users and limiting the touch issues. I still dont think its possible to have perfect latency and perfect touch due to our phone but here's what has been done..
Great work as always, glad to see you here! NGK was one of the best kernels for OnePlus 2, I'm excited to see what NGK brings in for Poco. You deserve much more appreciation for your work, I am doing my bit. For whosoever appreciates his work, following is a crowdfunding link that we created for getting Pierre a Pocophone, as he does not own one. Just to be clear, he isn't involved with this anyway, we, the OnePlus 2 family has done this on our own will, as a token of appreciation of all the work he has done for the community.

Havent been tested on Oxygen OS port yet.. Let me know how it goes! I'm not really into screen overclocking unless you want your screen to be damaged in a year... :cyclops:
Nice Work
Will Post it in Poco Official Channel:highfive:
Thanks for the effort! Although it's weird that almost every kernel devs are saying that CPU OC is not possible/necessary in recent SoCs anymore.
Will the source code be available? Can you create a script to easily run the build process for the kernel so that we can mess around with it?
Congratulations bro
Flashed the kernel, but the no gravity app doesn't detect the kernel.
Edit- My bad, it says coming soon in OP.
Legend is now working on poco. So lucky to have you bro.
quick question, if i have drunk optimus installed, how do i change it to this kernel?
and how to update it?
thanks!
Awesome bro... keep it up..

ArrowOS
ABOUT
ArrowOS is an AOSP based open source project started with the aim of keeping things simple, clean and neat, both for the Android system and users. We understand the pain of unnecessary and sometimes rarely used mods/features being shipped with custom roms nowadays which may end up causing battery drains and/or memory leaks & crashes. This is being strictly avoided on our side keeping everything to a bare minimum, delivering stable performance all the time without destroying the AOSP interface. With users getting more used to tweaks and features, we added just the right features and customisations that will be actually USEFUL at the end of the day.

FAQs
Q: VoLTE icon is missing! How can I enable it?
A: Settings -> Display -> Statusbar icons -> Enable VoLTE icon
Q: No dark mode in Phone and SMS apps!
A: Either install Google Dialer and Messaging from the Play Store, or enable "Override force-dark" in Developer settings
Q: Where is Dirac audio enhancer and how can I enable it?
A: Go to Settings -> Sound -> scroll to the bottom
Q: 2 Big cluster CPUs are always offline! Not able to turn them on!
A: When CPU load is low, these cores are turned off to save power. They will turn on automatically when CPU load increases. If you still want to turn on cpus disable core control in EX Kernel manager or a similar app.
Q: HELP! everything was fine until today but suddenly my screen stopped responding to touch and I had to reboot!
A: It turns out that k5/plus units with certain display panels have some issues with DT2W (double tap-to-wake) enabled. You can go ahead and disable it in display settings, the issue should disappear after that.
How to download this ROM?
I keep failing
Hi adityhya rom I use the way you say performance has increased really good rom now I wish you more success and new privatization plenty of roms waiting for you to meet us
I used this rom for a short time (I'm still used) It is very stable at the same time and curious item, the front speaker played ringing sound (too useful because my rear speaker is rusty)
Launchair bug does not open after reboot
And the battery consumption is very high, consumes a lot and it takes a long time to charge.
Other than that, great rom.
V smooth so far, it's the third day i m using this rom, no issue at all, the enhanced sound is v nice feature,
The battery consumption is a bit high, even in deep sleep
Thanks so much ,Good job ??
Dev kind request can you add rotate settings for rotating screen 270* because lower half of my screen doesn't respond so i have to use it in reverse
Please help
CPU core release does not work. After performing the procedure, the cores are momentarily unlocked but after a short time lock again.
Can i update it dirty ? Or it has to be clean flash ?
Is it possible to pass safetynet with this ROM and microg?
Thanks for the rom.
How can I turn up the volume on my headphone?
And the call recording option isn't working, you can't hear what the other person says
The phone freezes randomly from time to time and it goes to lock screen where I have to enter the password to unlock the phone
How can this be fixed
What causes it ?
Cast screen restarts the phone suddenly
Im using the last update 19-1-2020
It used to work with the previous updates
Thanks for still keeping alive this outdated device !!!!!
But i am missing Dolby Atmos that bassy speakers ....
I tried installing dolby from magisk module but the rom crashed. can anyone give me link for the dolby Atmos which can suppprt this rom...... Thanks for the rom
Poor call quality reported by person on other end of the line - A6020, Q, Arrow OS
Hi,
First - When I call or someone calls me, the voice of the person on the other end is loud and clear. But the person reports that nothing of what I say is audible. There is too much of noise, or a howling voice is heard from my side. The issue normally occurs when there's HD calling b/w me and any other user (And both have Volte active).
Second - Google voice typing, WhatsApp voice messages and voice recorder does not record anything from the microphone.
Third - Pls add a tweak for mapping hardware buttons in settings.
Fourth (And of very little need from my side)- Pixel Launcher crashes with full gesture navigation activated. Up to 2 button navigation, everything is fine except that from 2 button navigation, the Google app seems to stop working, often executing after a minute from being tapped on the icon and Google assistant doesn't activate.
Encryption worked for me, many thank!
First, thanks for extending the life of this model , second I have noticed that the battery consumption during use is high, I have activated the minimum, no application that works in the background, the only thing that installed extra was the magisk

Hello Everyone !!
I need help I bricked my phone , I was just going back to my stock rom then I am facing two problems ..
( I am not blaming this thread developer , I appreciate him for his work as I also used his ROMs )
Now my problems are :
1)-When I flashed stock rom using Qfil tool ,its showing baseband version unknown and I don't have any backup file for this ... So can I restore my baseband version.(does again flashing stock rom will fix it?)
2)-this is my main issue that my device is boot only when connected to charging. If I disconnect charger it suddenly turn off and won't turn on without charger...
And my battery is at good condition so I don't think its a battery problem.
Thanks for reading !!!
I hope anyone wil help me ...!!!

THREAD CLEANED
@dhaern @efinityy I read the messages and while I understand what you both were trying to say and where you guys are coming from, but please make sure that you're mindful of words you use to make sure they're not coming off as demanding, offensive, hateful, mocking.. well, you get the drift. I implore you both to re-read Rule 2 of the Forum Rules.
This is just a friendly reminder to keep it civil, on-topic and refrain from putting fuel to fire by responding to posts that you think don't belong in the thread. Just report if you feel something isn't right and let us take care of it for you, so that we can make your experience on the forum better.
Now let's all take a deep breath, and get back on topic, shall we? Thanks guys!

realy want to try this kernel but will be wifi fixed soon?
Thanks fot your effort dev.
You are only one who keep developing kernel for poco f2 pro
I have request I don't if it could be done or not
Many users complain green tint and black crush display and I figured out it may be something to be edited in display refresh rate and total pixels (like CRC app for overclocking refresh rate for windows)
when aggressive refresh rate is done or excess of total pixels added the screen turns to defects like tints and color crush
So if you can decrease total pixels untill reached it is minimum limit it will solve these defects for poco f2 pro displays

This sounds interesting, as this is an issue i have alot, especially with DC dim turned on, spotify for example has a green hue from top to bottom, fading the further down you go
EDIT; upon looking through the commits i can see some fiddling is done with the screen, hopes are high
