Samsug A36 kiling app.

Have you checked if an issue already exists for this bug?

• Nobody else has reported this bug before

Have you tried restarting your device?

• I have tried restarting my device and that did not help

What happened that you did not expect?

The kemapping ceases to function after the device is idle for a period of time. This problem is UNIQUE to Samsung and doesn't occur with my other Android Devices.
Rebooting the device will fix the problem, but it is a slight annoyance. I have searched high and low to disable battery "optimisation" on anything that could be remotely related.

Extra info

• My device is rooted

[sds100]

have you remapped the buttons with Expert mode or normal accessibility service?

[DanielJBer]

Expert Mode

[sds100]

If you do not remap the device with expert mode, do the buttons still work normally on your samsung phone after this idle period?

[DanielJBer]

I can remap them by using regular remapping and let you know. There is one key that I cannot use that way but for the sake of troubleshooting I can do without it.

[DanielJBer]

I performed the experiment and it made matters worse, actually. Remapping would shut down in about 5 minutes.

[sds100]

That was with normal accessibility service and expert mode disabled?

[DanielJBer]

It wasn't clear what you are requesting. Do you wish for me to try using keymapper mode instead and see if it becomes disabled?

[sds100]

Can you do the following experiments:

1. Normal key map with accessibility service. Expert mode disabled/stopped.
2. Expert mode key map.
3. Key Mapper completely stopped. Accessibility service off, expert mode stopped. I want to see if your phone has any weird behavior when it reconnects.

[DanielJBer]

Will do. I am currently testing normal mode with accessibility enabled

[DanielJBer]

Okay. Here is what I have found. When running in Normal Key Mapper Mode, it remains stable and is NOT KILLED by the device over time (tested for 3 days being idle.). The problem occurs only when it is running in Expert Mode.
Accessibility Service is required for the application to run.
