About double click the screen to wake up the device.

[Yu_Cloud]

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 ）

Currently I don't know how to add DT2W support
You can search Google for it

I'll try to add it but after some time

Sorry

I can't do it.But I found the twrp recovery can run like DT2W.I think the twrp recovery may used DT2W.

And I have to say sorry to you. Due to the GFW,I can't reply you in time. Really sorry.

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!!!
