I have found an app which can enable double tap to wake …
I haven’t tested the battery performance with this but if any one is willing to install …please do share stats regarding performance and battery life .
I haven’t used it on my watch, but I used it earlier on my phone
It drained a LOT of battery, as the touchscreen remains on, waiting for user input
But i think this should work well with amoled screens…because black screen should not affect amoled …and it does have a doze mode (for root ) which turns on automatically as the screen locks.
It’s not about the amoled panel, it’s about the touchscreen panel(digitiser)
The two are different, so it won’t matter if the screen is amoled or lcd
