Using Huangshanpai, sometimes pressing key1 once doesn’t wake up the screen—it requires pressing several times consecutively to work. Has anyone else experienced this?
Probably a faulty button? I tried it and it wakes up with one press. You might want to look into the hardware cause.
The statement that pressing key1 once cannot wake the screen is too broad. Is it that the key interrupt did not occur, or that the key interrupt occurred but the subsequent screen wake-up process did not proceed? You can add debug logs and further investigate based on the log.
Connect the battery. The default charging chip cannot maintain a constant 4.2V, causing the voltage level to fluctuate after pressing.
Found the issue. The touch panel and display share power, which sometimes causes the touch panel’s I2C initialization to fail.
