[ROM][SM-T825][UNOFFICIAL] LineageOS 14.1 | Android 7.1.2 20180301 - Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &

I'm not responsible for any damage to your device of any sort.
By flashing this you take responsibility of anything that happens.
Process at your own risk!
If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.
The last 3 weeks we with @bonuzzz worked hard to make stable firmware for t820 and t825 tablets.
Finally, it's time for the first release.
Instructions
1. Install twrp
2. Download the zip(s) - firmware and Google Apps additional package (optional)
3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei
4. Full wipe all
5. Flash firmware and gapps
Work
Almost all working
Known Issues

Thanks
Thank to my good friend @bonuzzz
Thanks to LineageOS team

Thank you so much
I hope the ROM is always better, as soon as I have some time I install it to report any bugs

Thank you very much!!!

I really dug the samsung apps for the s-pen. is there a way to install them after installing lineageOS? (sorry for the newbie-question)

Hi,
i've installed the ROM yesterday and i used it today in case of a working day.
I have noticed that he unfortunately does not switch to LTE - despite full receipt. The tablet uses at most HSDPA, which makes the ROM for me currently not really usable.
It is also a bit slower than the stock ROM, but tolerable - only the network connection is still a hindrance.
I bought the tab because I thought, as a flagship this device will surely get the lineage OS.
I am still very enthusiastic and really thankful that someone has made such a great ROM for this tablet- many many thanks to the devs!!!
regards
Ralf
Edit: after reinstalling this ROM is found the switch to change the preferred connection type to LTE. So i go on using it

For the 820 the GPS is not working.
Can we expect the same with this 825 version?
Thanks for your efforts!!

Ok so, I gave the rom a chance and to be honest it works quite well.
Kudos to Valera and Bonuzzz for the effort, this is looking very promising.
I don't use the S-Pen nor the phone-calling stuff so, my experience with this build doesn't include those two.
General usage feels snappy, I only had some trouble while playing video streams on the stock browser and firefox. The problem went away while using chrome.
Tried a couple of HDR 4K files on MX Player and they seemed to play nicely.
Played around with the settings, everything cool.
The only problem so far is a huge battery drain during normal usage.
Aside from that, this is an excellent beginning.
Considering this is just a 1st release, it's very stable.
If you need any kind of testing, I'm more than willing to help.

kainanmaki,
Thanks for the initial testing. I have not flashed this ROM yet. I'm still observing a bit before I do so.
I'm curious, how do you define normal usage? Also, are you able to quantify the huge battery drain?
Thanks much!

Well, you should. At least it could give you a good idea of what to expect when the rom is ready.
I have never used lineage on a tablet so I wasn't sure what to expect.
For starters, normal use is just what you can imagine, youtube, chrome, mx player (hdr stuff), headphones, couple of silly games.
After checking how stable it was, tried Xposed -sucessfully- and every module worked fine (amplify, bootmanager, rootcloack, xnotify,youtube adaway). The drain is severe, you could literally notice the % going down ridiculously fast.
What's worst, my normal app usage and settings are designed to not duplicate what I can already do on my HTC 10.
So no GPS or Bluetooth, almost no applications doing sync stuff that I already have on my smartphone. (Gmail for e.g)
I always force wifi to sleep when display is off. Again, I don't need another device duplicating my smartphone.
LTE data is also off most of the time (and LTE works as expected per Speedtest -70 mbit-)
But again, settings are tweaked to maximize battery, while using it and while sleeping.
I have used BetterBatteryStats to take some measures, the drain is related to the core of the OS services.
A simple comparison with Stock. I just have started debloating touchwiz (very happy with the progress there too TBH), and barely scraching the surface of what can be done on stock, BBS is reporting 6.25 minutes per 1% of battery. Roughly 10 hours of battery of non stop use. After removing 85% of Samsung bloatware and its services, it's going to look even better. Samsung never ceases to amaze me with their never ending junk. So again, the rom is not ready for primetime. But that could change fast.
IMHO, you should install TWRP and do a backup of stock stuff and take a dive. Even if Lineage feels like android for smartphones, still works wonders. And you can go back to touchwiz in 3 minutes...
EDIT: Forgot to quantify the drain. The android energy forecast estimated 3-4 hours for a full charge. Closer to 3....

i wish there was developer who would give us debloated, tweaked stock rom .. i know this is not the right thread for making this post, but still

Massive screen-off battery drain with all ROMs

Hello everybody,
about two months ago, I had an issue with my installed ROM on my Redmi Note 2 Prime (I think it was this one: http://forum.xda-developers.com/redmi-note-2/orig-development/rom-cyanogenmod-12-1-t3288916 ). I decided to try out another ROM so I installled Bule's Mokee ROM ( http://forum.xda-developers.com/red...nt/rom-cm-12-1-mokee-bule-mokee-blue-t3328382 ). After a few days with this ROM I recognized a big battery drain while screen off so I installed BetterBatteryStats to get some more informations. It told me that about 50-75% of the time my CPU was running at 800mhz instead of deepsleep (at a normal day with about 1-2h of Screen-On-Time). It didn't look to me like something is creating a wakelock though (but maybe I am just unable to see this). I tried the next ROM: Daniel Pinto's CM12.1 (http://forum.xda-developers.com/redmi-note-2/development/rom-unofficial-t3310551) and again the same issue! I tried a full wipe of my internal storage, did not install xposed and did not install any titanium backup. The battery drain didn't go away. So i flashed another ROM: SlimMIUI V7.1.3.0 ( http://forum.xda-developers.com/redmi-note-2/development/rom-slimmiui-dev-stable-t3296594 ) and suddenly there was no more screen off battery drain! This went well for about three weeks and now I am facing the old problem again! Please tell me what I am doing wrong since I don't believe it's a ROM-related issue.
I installed these apps (according to MIUI):
9gag
AdAway
Android System WebView
Antutu 3DBench
Antutu Benchmark
AquaMail
BetterBatteryStats
BikeComputer
Burning Series
Chrome
DB Navigator
Dropbox
ES Datei Explorer
Google Play Store
Google Play-Dienste
Google-Tastatur
Greenify (wasn't installed before SlimMIUI)
GuitarTuna
Hacker's Keyboard
Hearthstone
irplus
Maps
Messenger
MX Player
mydealz
No-Frills CPU Control
Nova Launcher
Open Camera
PaderSprinter
QuickPic
scondoo
SleepTimer
Spotify
SuperSU
Telegram
TeslaUnread
Titanium Backup
Twitch
Unified Remote Control
Wakelock Detector Free
WhatsApp
Youtube
What I have tried so far:
- changing ROM (clean flash)
- not installing xposed
- not using old backups
- changing the battery
- using airplane mode
Also, I wonder why there are these gaps in the battery history since I didn't reboot yesterday...but these gaps don't appear every day.
Please help me to fix this really annoying problem and make my RN2 great again!
Thanks,
Kooneybert
The biggest drain comes from all the Xiaomi bloat. Read this thread for details on how to reduce the bloat. In my experience, the second main culprit is WhatsApp. I've had to stop it from giving sound notifications (or even vibrating) when messages come in. Now, I have between 90%-95% deep sleep on idle. Basically, anything that turns on audio could be a problem, because sometimes audio doesn't go off afterwards.
You might want to try GSAM Battery Monitor for more information about what is eating up your battery.

Thx for your reply! The problem is not MIUI-exclusive. CM 12.1 from Daniel Pinto is pretty slim but gave the same result (from the first day on).
Whatsapp can't be the only problem since all my friends use it and nobody have this problem (some of them also even have a RN2). Also, my phone is in silent mode almost all the time so no app is allowed to make noise or vibrate.
I just installed GSAM Battery Monitor but I don't know how to use the app/read the provided data. I could use some help there, too.

You can only be sure if you have a really skinny ROM whereby all the unnecessary Xiaomi stuff has been removed. There are all sorts of things going on in the background - including things embedded in the boot image.
There are also possibly optimisation issues with the kernel. All the ROMs seem to depend on the same binary kernels, since there is no GPL release of the kernel source code. You might want to try one of the skinny boot images by @jajk
As for GSAM, the best to learn is by trial and error (tip: tap on everything visible to see where it leads to, and what information it gives you).

...on all three ROMs? Only for me? With this effect? On some days, it reduces my battery by 50-80%! Hard to believe it is not a bug. Also, SlimMIUI has reduced Xiaomi-Stuff, Daniel Pinto's CM 12.1 looked even more clean to me.

Aren't there different kernels out there for the RN2? Bule's Mokee-ROM uses a modified kernel e.g. Does every ROM come with a certain kernel or may it be applied from the ROM before? So maybe I am still using the kernel from Bule's Rom with my MIUI?

This will help me to read the information but it won't help to understand them, too. What do you think about this:
Kernels: You can't compile a custom kernel without the Xiaomi kernel source code. All you are left with is tinkering with ramdisk in the boot image

...is this normal? The Kernel is the biggest battery sucker on my tablet aswell (which still has great battery). What do you think about the 8,5h of wakelock time produced by the kernel? If this is the problem, what can I do to solve it?

A "screen awake" of approximately 50% seems to me to be highly excessive (at least, if the phone was mostly idle). In nearly 12 hours, I have a screen awake of 55 minutes - so 8 hours in 15 hours seems strange. How exactly were you using your phone during this 15 hour period?
Perhaps the custom boot images by @jajk might help (see the first link in http://forum.xda-developers.com/redmi-note-2/general/roll-skinny-miui-t3309873). I am currently on v714-15 of the custom boot image.
Sounds like you may be having issues similar to what I was dealing with not too long ago, but my 'solution' was to install Bule's Mokee (still don't know why this ROM worked where so many others failed). Daniel's CM 12.1 and Xiaomi.eu were both giving me significant drain with and without the screen on to the point where I was sometimes finishing the day with an hour and a half of screen on time and ~20% battery. Now I'm getting up to double that.
One thing I can recommend is using MiFlash/Fastboot to do a total reset from scratch. Didn't really work for me, but you may be different.
Other than that, although it's tedious, you may have to install 1-3 apps per day after a fresh install to see if your battery holds at first and then dies sometime after installing certain culprits. It takes forever, but at least this helped me when I moved to Mokee to make sure that it wasn't any of my 'vital' apps that were causing me issues.
Best of luck!
Funny thing that the Mokee-Rom did SOLVE your problem. In my eyes this Rom was the beginning of my problems.

What is the difference to using TWRP?
I will try the Mokee-Rom tomorrow. Since I never used MiFlash/Fastboot before I won't use it until you tell me that there is a difference compared to doing a full wipe with TWRP.
I tried flashing the Mokee-Rom again but the problems go on. I installed very few apps and the battery is still very bad. Today I had 18 minutes of SOT and though I lost 14% in a few hours. This time it was caused by Whatsapp:
It always seems that some apps just don't like to stop doing something but it's random which app is the problem.
I am totally running out of ideas so please help me guys!
I'm on Mokee and satisfied with battery, this rom have less problems than other (for me). First of all i have installed MobileRadioActiveFix with xposed, then SmartNetwork to turn off wifi while my screen is off. I've got few other things but right now i've got over 4h SOT so it is not bad score.
i have the same problem! it happens with flashing severals ROMs (mokee by bule?) and starts battery drain with all ROM, it never goes... is not the battery, the cable or the rom..... i dont know im disperate... the sot changed from 4-4.5 h to 2-2.5 h... with all ROM, please help us and sorry for my bad english
Well i had situation that my SOT suddenly got down but i was still on march rom. After update to latest version without wipe it is ok right now.
Have you tried with wiping all with internal memory? Maybe something is there still and that is making a problem.
Another thing that came to my mind: have you changed build.prop and have copy of it? If so, delete it. I had some problems becuase of that.

every rom i have flashed was a clean install (full wipe of internal) after latest miui update, when the phone shut down at 0%, i put off the battery for 10 min, after i put back and the phone was at 19%!! now is on charge... maybe the problem is solved.. i will post if it is solved (sorry for my bad english)
I had that problem with earlier phone and it drived me crazy. I was not able to find what was the cause unfortunatelly. Phone was given to service point to install branded rom (it was not available for public). Right now i do not have problems like that, if i have some i'm able to find solution somehow. Although what i wrote helped me when i saw SOT problem.
problem persists... is there a method/app to calibrate battery that works?

Not that I know of. I`m facing the same issues like you here.
You can try:
-discharging until the phone shuts off
-charge it in OFF mode until its full
-disconnect charger, put battery out and in again
-connect charger, charge it to 100% again...
repeat until it shows 100% when connecting the charger.
For some ppl this seems to work.
Please let me know if you find out something!
There are lots of ppl out there with exact the same issue!
BR
EDIT: Installed PSYROM V3 for testing purpose right now. Lets see how it does with skynet and a freshly calibrated Battery with the internal calibration tool of the rom. I`ll give feedback on monday.
Update to my issue:
-I did a full wipe (including internal memory)
-Installed PSY ROM V3.0 and Skynet
-Wiped cache/dalvic
-Startet the phone, installed my apps etc
-Charged it to 100%, waited 20 more minutes
-Did the Battery calibration with the internal calibration tool (everything is described in psy mans thread)
-Did a reboot
So far there is no Battery Drain, after the (long) reboot, wich took around 5-10min because miui is optimizing apps etc the phone came up with 97% and stayed there for almost an hour now.
I´ll give you guys feedback next week. Hopefully we get this sorted out.
You can try Angels & demons ROM v8.0 it is providing me with great battery life, so much better than stock or stable version of MIUI. I use Gsam battery monitor, and I have not faced that issue so far.

Not sure about video tutorials, but there are multiple guides available here in xda to repartition your phone to increase system partition size and to be able to flash any rom
U can follow this guide if you prefer using pc, it's easier for me as well:
http://forum.xda-developers.com/gal...vatives/mod-increase-partition-size-t3011162/
Or this tool made by lanchon for non pc users:
http://forum.xda-developers.com/android/software-hacking/tool-lanchon-repit-data-sparing-t3358036/
I believe there is a video guide somewhere, you can try googling, and you may find It.

Battery depends on how you use the device more than it does on what ROM you're using. It's all in how you use it.

It depends on your usage at first, and the stock rom or stock based roms are the best battery life roms.

well, as i told you it depends on usage, i uninstalled Facebook and i used lite instead, but after all i don't actually reach 3 hours on lineageOS 14.1, but the stock rom or neat rom are the best in battery life, you also might want to try latest slimsaber kitkat build, it has great balance between performance and batterylife, i'm on AICP 12.1 build 7/2, the screen on time isn't bad but something is wrong with screen off, it drains battery, might be a wakelock issue......or if you want to stick to lineageOS, you can just relieve your mind, and buy an extended battery, because our battery isn't built to stand high system usage like in newer androids..

Custom stock-based ROM like NeatROM will make it possible to reach 3+ SOT depending your usage and hardware. Using Apolo kernel with small UV may be able to extend your battery life slightly.
Slimsaber KitKat is one of the ROMs I've tested to have comparable battery life while maintaining good performance. Anything after KitKat is slow and bloated (also heavily depends on RAM management and etc).
Wow
That helped alot bro thanks....
No problem with the battery
I'm using OFFICIAL 7.1.1 LineageOS 14.1 on my GT-i9100 with 1-6G pit.
I have done much reading about the subject and few experiments - so the following, so far, works best for me and i like it(i dont have any games nor chat apps):
I started with nano gapps and then installed ca 20 more apps.
I have a new battery "Polarcell" - i kept strictly its manufacturer instructions about first time use.
About the battery levels i'm using few methods on my rooted phone:
- "Power save" profile all the time.
- one program for apps hibernation in which i added many apps to take care of( i don't really know whether that helps ).
- In the "Kernel Adiutor" i changed on boot three options - CPU Governor "Pegasusq", I/O Sheduler "Noop" and TCP Algorithm "Reno"
- With another app i disabled "starting on boot" most of the programs which i don't see a reason to be active right after rebooting.
- I don't know whether this is relevant to you but check if google voice is using your mic all the time - i had that problem with my guitar tuner app.
- My Home screen is completely black with 160bytes png-24 little file.
- I'm trying use dark themes with all apps when possible.
- No Shadows under the text of the apps names.
Of all 7.1.1 ROMs this one(OFFICIAL 7.1.1 LineageOS 14.1) works best for me in all aspects and i'm very thankful to the LOS team.
Btw: I have tested other most popular 7.1.1 N roms and with one of them after i woke up my phone was shut down - 0% battery.
Just sharing my experience with the hope that it will help someone.

- one program for apps hibernation in which i added many apps to take care of( i don't really know whether that helps ).
- In the "Kernel Adiutor" i changed on boot three options - CPU Governor "Pegasusq", I/O Sheduler "Noop" and TCP Algorithm "Reno"
- With another app i disabled "starting on boot" most of the programs which i don't see a reason to be active right after rebooting.
- I don't know whether this is relevant to you but check if google voice is using your mic all the time - i had that problem with my guitar tuner app.
- My Home screen is completely black with 160bytes png-24 little file.
- I'm trying use dark themes with all apps when possible.
- No Shadows under the text of the apps names.
Of all 7.1.1 ROMs this one(OFFICIAL 7.1.1 LineageOS 14.1) works best for me in all aspects and i'm very thankful to the LOS team.
Btw: I have tested other most popular 7.1.1 N roms and with one of them after i woke up my phone was shut down - 0% battery.
Just sharing my experience with the hope that it will help someone.

Can you provide a list of apps you use for hibernation and power saving?
Also Can you tell how much is your usage of social netoworking/internet apps? Like 2 hours 4 hours a day or all day? Does Viber/WhatsApp etc keep running and WIFI is connected all day?
Also do you use WIFI most parts of the day or 3g/4g network for data?
Can you tell how much hours a day you spend on calls and how much on SMS? E.g. 1 hour or SMS and 3 hours call each day?
What kind of battery do you use? What is the current rating of the battery?
Lastly, how many hours of screen time do you get with no calls? How many hours of usage with 2-3 hours of calls each day? How many times do you have to charge your phone with your current setup?
I am using DND on my i9100 and I want to change it. I use a double battery which I checked (via digital multimeter) that offers 16Amps (8Amp + 8Amp =16,000 mAh) but still with no usage (just receiving sms, not sending), I get only 2 days of standby time. With internet usage like Viber+whatsapp, i get maximum 6 hours which compared to available power in the battery is very less. I should be getting more time.
Can you please reply with the details in my request? Thanks

Are you saying that the new battery is dead? Are you saying it won't charge?

Very poor battery life

I'm getting very poor battery life with my Note 4, which seems to be much worse since a recent update. When I first got the phone a few months ago the battery life was fantastic but now it's almost as bad as my old Moto G2!
I get up in the morning and over a couple of hours spend a bit of time (not constantly for 2 hours) on WiFi checking e-mail, social media, etc. and my battery goes from 100% to 70%. Then I don't use the phone, go out for about an hour listening to Spotify music (offline) using my BT earbuds and when I get home it's down to 40%.
As you can see from the screenshots, it doesn't seem to be the apps I'm using that are draining the battery as "Android system" is responsible for 74% of the battery use. This has maybe 50 packages listed under it, so I think it will be rather hard to identify which one is responsible.
Any ideas what I can do to fix this?
Are you using MTK or SD?

Dont use MIUI, that's a good start. (hopefully you have Snapdragon variant otherwise you're screwed)

I can't remember how to check but I'm 99% sure it's SD. It's mido if that proves anything.
I installed Greenify and hibernated a few things and that's helped a bit, although it's still not brilliant. I also installed Amplify but the results don't mean anything to me, so I've attached some screenshots in case anything stands out (more in next post due to max.4)
Remaining screenshots.

Yeah I've been thinking of changing ROM tbh. Something that annoys me about MIUI is it only allows you to enter a numeric decryption code on boot. I know how to set it to something different than the unlock code and normally use an alpha-numeric code but that's not an option with MIUI as I wouldn't be able to enter it!
I have App Quarantine installed so I was thinking I could try freezing certain system/MIUI apps but if I'm going to change ROM I guess it's not really worth it. The problem I have is choosing a ROM, as there's so many and battery life, whilst important, isn't the only thing that matters to me. The decryption code thing is important, as is full dual-SIM functionality. OTA upgrades is one thing that MIUI has in it's favour and I guess that's not an option with third-party ROMS but upgrades being made available in a way that they can be installed without wiping the phone would be nice, if possible. Dual apps, Second space and Call/SMS blocklist are all quite handy features in MIUI too.

MiracleDROID, give it a go, it's one of the better ROM's i have used on Mido very underrated.
Or OmniROM if you want weekly OTA (Delta updates) just like in MIUI.
And dont expect miracles right after flashing it, give it atleast 1 charging cycle to settle.
Same problem with me .. Battery temperature goes to 41 degree ++ and after night I have to see my low battery

Oreo, Note 8 never been the same after

I am frustrated user of Note 8, received it early September 2017, been using without any issues until Oreo update arrived in May 2018.
Once phone was updated i have done factory restore and start clean, i have done same procedure twice as i am having the following issues running phone in high performance mode:
1. The phone used to run smooth in Power Saving Mode, now its sluggish
2. Pretty sure there is greater delay between finger print sensor reading and screen turning on
3. General UI laggy, in performance mode its no longer as snappy as it used to be
4. The edge panel can sometimes slide out but stutter on animation
5. Camera launching from the hard button press, can have delay or stutter to launch too
6. Battery feels like gotten worse
Anyone else can agree?

Are you on the original Oreo update?
Never had any problems...
I agree with OP. It has gotten worse. I use to go a full day without having to charge it. Now after Oreo, I'm at near 78% after 4 hrs of YouTube background play compared to 86 to 84% on nougat.
factory reset your phone. my battery and performance has only gotten better since 8.0.
Got to agree with everyone I'm on AT&T Note 8 running smoothly like butter no issues at all on Oreo.

This is nonsense, Note 8 got better with every Oreo update month by month, everything is butter smooth and battery is better than Nougat.

How is it nonsense? So because yours and others work fine, this person can't be having issues? Why do people keep making such ignorant statements without thinking things through?!
Others have had a bad experience with Oreo, and not just a handful(5).

He is probably busy posting other nonsense replies.
Have you seen any similar threads to mine with resolution? I dont sign in here much anymore, partly due to Note 9 software been so good that I felt it needs no rooting and was happy with stock setup and apps from Google play store.

I disagree. My Exynos N950F has still been smooth since the day I got it out of the box. I only got the base update to Oreo (possibly due to my CSC). My experience has been good so far. My phone has never been sluggish while playing games or multitasking using multi-window or App-Pair (whatever the feature is called in the GraceUI).
I'd suggest you backup, wipe (again), and restore your phone in increments until you find the root cause. I'm willing to bet that your issue is with an app that runs in the background. Are all your installs from the Google Play Store, and not APKs from questionable third parties?

As I said I won't be resetting for 3rd time, if it was dirty app I would of identified. If you are familiar with recent android features if got pretty at identifying bad apps too.
After each reset I gradually loadedvphone with apps and settings.

I'd flash latest full stock with Odin using full wipe. Better than factory reset for clearing out persistent issues. Aside from that not sure what else can be suggested. Oreo has been running great here with every OTA.

I suggest downloading the firmware of the version you are currently on if you care about rooting in the future and flash it with Odin. Seems like you're on v3 bootloader based on your post. Go from that direction with testing.
I agree with the battery being worse. For me standby drain is way higher on Oreo. On N I would lose about 5% overnight. Now around 11-15%. Phone is smooth though
Yes I agree oreo is laggy and a battery hog on my at&t note 8. Other then the android version being different I see no visible ui changes vs 7.1.1. Why do they keep changing the bootloader? Dont understand that.

Do you have a Snapdragon or Exynos device?
My Exynos N950F only drains 1% overnight, but I only got 1 update TO Oreo since I got my device (out of the box).

Android P Improvements

After 2 days usage, I can tell that they're a lot of improvements but something worst after upgraded to Android Pie.(I'm not talking about changelog)
===Improvement===
- Take less time to open apps(More faster than oreo)
- Overall performance increased(Before update I got 179K scores on Antutu)
- Faster rendering stuffs(NOT sure I felt it sometimes)
- Better Ram Management ( Adaptive battery actually restricted usage of unused apps)
- Bluetooth battery check on wireless earbuds or wireless headphone. ( I didn't see that on Oreo.)
- Lowest Bringhtness actually lower than before? ? (I can't confirm this.)
- And many more I can't remember ?
===Worst things that happened after update===
- Battery actually drained a little bit more faster than oreo. ( Even on screen or standby.)
**** the battery life is better after the Adaptive battery things identified the battery drain apps.****
- Mobile data sometimes shown no connection. ( I have S7 edge and it's got like 3/4 signal but in xz1 there's only 1 /4 signal or no service. ( I'm pretty sure about this)
-WiFi sometimes shown that connected but actually it doesn't load my YouTube video (Tested 2 times with S7 Edge and confirmed the problem.)
- Night mode actually cool but doesn't work right now?(It's new thing I know but just complaining about it)
Sooo if you guys find anything other than this you might wanna leave the comment so let me know the thing that you might notice like improvement after update to pie. ?
Thanks for visiting and read all of my stuff?

Is the smartlock-bug fixed? I mean where the smartlock feature stops working after a reboot.
Are the touch sounds the same as Oreo or do they use the ones for XZ2/XZ3? It's the one question I did not get an answer for in one of the other threads.
did Sony update the driver of Adreno540 or still using the 251 version?
that can be checked in aida64/display/GPU version

Ok googel not working?
The best thing is that now DRM doesn't matter.
The Camera works with unlocked bootloader and doesn't need any fix!
I'm using phh treble rom 9.0, you just have to flash magisk and it will boot.
You are missing: new camera app with super slow motion 960pp in full hd (1080 p)

Oh phh treble rom boots and the camera works?! This is good news. This means that the other treble roms will boot too since they are built on top of it (I think).
Edit: Mind posting a short guide? Maybe even as a new thread, I'm sure many people are interested.

You can check my post here... basically what I did:
1- Update to Stock 9
2- Unlock bootloader
3- install TWRP
4- Flash A-Version GSI AOSP Android 9 from Phhusson, I recommend the gapps su version.
5- Flash Magisk
Done!
Later I did some experiments using gapps to install google camera 2 (legacy) and it works!
For me the best things in the Pie update so far seems to be battery life improvements. In previous 8.0 builds battery management in my XZ1 was somehow broken. It got massive drain overnight and even when I unplugged it in the morning, I only managed to get 3-4 hours of SOT during the day. Now with Pie it looks like this issue was fixed. Energy use of android system and phone standby is stated to be around 1-2% of the whole usage (previously like 20%) and the SOT is exactly like in the good old days when the phone was new out of the box. Today (with battery-priority stamina starting at 20% and all-time enabled mobile data, wi-fi and accurate location services) i got a massive 6h 23m of SOT. I'm very curious if this will become a typical score right now.
