do you enable dt2w on settings? If it doesn't work you can try download kernel adiutor on play Store. Open it and go to wake and enable it on boot. See if it works.

If settings and kernel adiutor isn't showing d2w then probably it isn't supported by your display.

maybe your stock kernel don't support DT2W . You can try custom kernel that support dt2w ie Franco kernel . But before that make a backup first before doing anything.

I got 2 mido, 4x both, black one works perfectly and when i boot in to recovery redwolf, it takes double tap to wake from black screen, blue one is the problem here and redwolf takes ONLY single tap to wake, and i cannot use dt2w on official miui either, whats wrong with my device

maybe the device is the older one. one which was being produced before xiaomi opted for some other type of screen

maybe you got defective one, only one way to know it you must go to the service center and ask them to check it.

Thank you guys all #MyNameIsRage and #Zasnizas

[Kernel] DoubleTap2Wake for Sony stock rom (757)

Here is a beta version of dt2w for 757.
A known bug is the screen unlocks when u double tap the screen the two times.
Maybe @blueether could help with it.
The funny thing is the bug disappears when I logcat.
It seems the bug only happens to me lol. Never mind
Here is the kernel:
Link deleted due to permission reason.
Sorry about that.
I will send a pull request and open source.
Enjoy!
I was going to do that today, I guess I'll have to find something else to do today
Did you include recovery/ RIC disable?

Yes. It includes dual rec and RIC disable.
But there is something wrong with the driver.
The screen only unlocks when u do double tap two times. (double tap once, then double tap)

when the phone is on charge (so adb) it will work flawlessly as I think the screen gets put into the next power state, this is the main problem with the dt2w.
Do you have an extra screen protector on? I think that that may be part of the problem

No, I do not have extra screen protectors on.
Dt2w works perfectly on CM based rom. But not on Sony stock rom.
I have people test on their phones, they have same problem.
Maybe Sony stock rom have special power management?

Just changed the file and recompile.

Just flashed and working fine at the moment. Only double tap once. And beautiful splash screen. Love it dude. Thank you. I'll report issues when they arise.

I just found out dt2w works in TWRP recovery. I only need to double tap once.
It should be a system issue then.

[KERNEL][D618 & D620][DT2W] KeyHandler Patch

To make doubletap2wake feature work in CyanogenExtended kernels you should once downoad and flash .zip (compatible with your device & ROM of course) to add KeyHandler support in system (external module which enable screen when kernel sended a message (KEY_DOUBLE_TAP 251) to it that you make doubletap).​
For Cyanogenmod 12.x:
D618: KeyHandler already is in ROMs, you don't need to do flash anything.
D620 (also compatible with any cm12-based ROMs): https://yadi.sk/d/btiBkgZXgvLNm
For Cyanogenmod 11 (only for clear ROM, not for it's based ROMs!!!):
D618: https://yadi.sk/d/OgON5Uz2guw33
D620: https://yadi.sk/d/XF8jJB1vgvLsA
For MIUI V5:
D620: https://yadi.sk/d/yaNS_hiUgvMFs
Another CM11-based ROMs (AOKP-4.4, CRYSTAL PA) isn't supported yet - if you want to help me with it just send me your framework-res.apk from /system/framework/ and write from which ROM is it.

So far I'm not able to bring that feature to life. Installed Kernel and Patch twice, did the settings - still it won't work.
Any suggestions?

D620 LG G2 mini.
Yep, I know.
Feature seems to work if I toggle on "Lift to Awake"- Function in Display-Settings, but with that the display wakes up every ten seconds.

Same for me here. I've downloaded nikita's kernel, and patch. Installed first kernel, then patch. Tried reactivating DoubleTap2Wake, and it wont work.đ
Also, I've typed command in TerminalEmulator that System_F mentioned with su rights, and nothing happens.

Yes, as I said, I first installed kernel, then patch... I didn't work like that, so I added command in Terminal Emulator, like system_F said, tried turning off and on DoubleTap2Wake in Display settings, but nothing happens.
OS: cm12
Phone: d620r
One thing I find strange, in settings -> About phone, phone doesen't display kernel info, but Kernel Auditor does. Screenshots provided.
EDIT: It appears I didn't have latest unofficial cm12 version. I have installed it, now works perfect.

About double click the screen to wake up the device.

Can I double click the screen to wake up the device through flash others ROMS ?
If I can , please tell me how to do it. Thanks!
This is called DT2W that is double tap to wake
This is mainly a kernel based feature and it can be integrated in a custom kernel for a device
& DT2W is battery consuming feature as it keeps touchscreen ON always which consumes battery
& I don't think any developer is making any custom kernel for this device
So it's not possible to integrate it in that kernel
& if a ROM supports DT2W then ROMs kernel would support DT2W then it would be easy to port that kernel for other ROMs also
But my opinion is DT2W consumes more battery & some times freezes screen so I will not go for it

No , it just need a little Battery. only a little . such as DT2W for mi4 or Nexus .
Do you know how to add codes into kernel to support DT2W ? I want to try it.
(I found that F2 's kernel has "mtk_battery"
F1(this Chinese device) doesn't support DT2W , but F2(F1 's plus) support it )

No worries about late reply,
Ya (I think - not sure though) that's right that TWRP supports DT2W
But it's quite complex for knowing which method TWRP is using from its source (noob at this kind of stuff).
You can have dt2w (Double Tap to Wake) if your phone have android 6.0+ since this feature is starting supported only above 6.0 roms!!!

[9.0][G8341-G8342][UB][.228] DT2W (Double Tap 2 Wake) Kernels

Below are Stock kernels with DT2W added. The kernels have been extracted from 47.2.A.11.228 firmware.
The kernels are SElinux enforcing (same as stock). They are in no way custom, all i have done is add the dtb from Iovf's .107 kernel to allow double tap 2 wake.
Some people have reported the DT2W feature requires a solid tap, and sometimes may not wake the screen instantly.
This is out of my hands, and capabilities, to do anything about.
Installation:
On stock .228 firmware:
Flash the kernel for your device in TWRP
Flash whatever Magisk.zip you prefer, and reboot. Once rebooted, install the magisk module below (DT2W_Magisk Module) and reboot.
(If you want permissive selinux, also install the Permissive module in Magisk at the same time).
eXistenZ users:
The kernels are also compatible. Same install steps apply (flash kernel, flash magisk, reboot)
If.you want to keep SElinux set to enforcing, use the DT2W_Magisk Module.
If you are using something to set SElinux to permissive for fonts (or whatever reason), you dont need the DT2W Magisk Module, only the Permissive module.
Also attached are the TWRP flashable stock .228 kernels.
Thanks to @iovf for the original kernels I pinched parts from.
Thanks to @shoey63 for the DT2W Magisk Module.

I use v20 on the XZP with no drama, can you try the dual sim kernel and let me know? There is no harm in using a dual kernel on a single sim phone. Thanks.
I tried these kernels, and it seems really inconsistent and finicky. However, I think I found the reason why there are so many issues with double tap to wake on the XZ1; a developer looked into implementing tap to wake and had this to say:
Myself5 said:
I roughly remember looking into this decades ago and the conclusion was that either the XZP/XZ1 kernel is super ****ed (beyond repair) or they have some sort of hardware issue causing the situations. When you used DT2W and combined it with using the power button in a specific order the touchscreen wouldn't work anymore until you turn the screen off/on again using the power button.

@Beetle84, do you know anyone who could look into this? It would be nice to see if this was a really bad software limitation, or just a hardware limitation.

Does that mean the XZ1 does not have the appropiate hardware for it? It's a shame if that's the case.
I used the single sim kernel, on existenz pie with the magisk module.

I believe its hardware. For the xzp, the dt2w code was ported (by a different dev than iovf) from the xperia x to the xzp kernel. Im not sure if it will get any better ever. Im not positive how iovf did it.
Thanks for letting me know about which kernel you flashed, someone above bootlooped using the single sim kernel, no idea why. Its kinda hard to test myself without the xz1... A few guys tested before i uploaded them here, so I don't know what happened for him/her.

Is there any way you could contact iovf to ask him/her? Maybe we could see if the method you mentioned for the XZP might be able to get dt2w to work on the XZ1.

Many thanks my dude.
I'm bit courious, as there has been only one person has mentioned what rom and firmware they are using, but for those that are using the the existenz rom have you tried going into the rom display settings and flipping on the dt2w switch to see if it helps..
see pic..
I tried to reflash everything with Magisk 18.1 but I have the same error.
But doesn't it work for me?

No idea mate, single and dual are confirmed working. Try flashing the stock kernel, magisk and reboot
Then try the dt2w kernel, magisk and reboot.

IIRC the Xperia XZ Premium got shipped with multiple touchscreens.
I can assure you mine is doing that, and I can provide you multiple other instances where it happened. I've been trying to use my XZP as a DD for around 2 months and had that issue nearly daily when DT2W was enabled. (Mind you, that was shortly after release though, so it's been a while).

There is nothing that was "ported". Both devices have the code for Doubletap to wake in the kernel. It's a single matter of replacing a "false" with "true". None of that is standard code btw, so isn't it interesting that Sony put effort into adding Doubletap to wake just to disable it then?
P.S: Why are you building Dual and Single SIM variants of the kernel?

IIRC the Xperia XZ Premium got shipped with multiple touchscreens.
I can assure you mine is doing that, and I can provide you multiple other instances where it happened. I've been trying to use my XZP as a DD for around 2 months and had that issue nearly daily when DT2W was enabled. (Mind you, that was shortly after release though, so it's been a while).
See above.
There is nothing that was "ported". Both devices have the code for Doubletap to wake in the kernel. It's a single matter of replacing a "false" with "true". None of that is standard code btw, so isn't it interesting that Sony put effort into adding Doubletap to wake just to disable it then?

Thanks for the clarification. Would it be possible for us to determine what our touchscreen manufacturers are? In your case, tap to wake is pretty glitchy. But, in @Beetle84's case, he appears to have little/no issues. It would be nice to see if different touchscreen manufacturers are at play here.

I made several optimizations so I would say that the performance is very good, if you tried bananadroid you could use it as a reference since I did the same optimizations there
the only thing I left here was the blur but if you want even more performance you can disable it

i made some optimizations to make the UI even smoother, things like increasing zram and forcing msaa 4x by default are some of them
