Description
Hello,
I am experiencing an issue with the Double-Tap to Wake (DT2W) feature on my Xiaomi 11i (codenamed pissarro).
The device wakes up using the power button without any problem, but the double-tap gesture on the screen does not work. This leads me to believe it might be a kernel-level issue, possibly related to the touchscreen driver or the feature not being enabled in the kernel config.
Model: Xiaomi 11i (Xiaomi 11i HyperCharge)
Codename: pissarro
Kernel Version: 4.19.191-perf-g6a48cffd42dc
ROM/OS: Hyper os all
Plz update mi code and plz fix this issu

Research direction
Start by reproducing DT2W on the Xiaomi 11i (pissarro) and inspect the touchscreen driver and kernel configuration mentioned in the report. Determine whether the gesture is enabled and trace where the wake event stops; done means double-tap reliably wakes the device without affecting power-button wake.
