--stay-awake isn't working on Pixel3a (Android 11)

[jpage4500]

• I have read the FAQ.
• I have searched in existing issues.

Environment

• OS: macOS
• scrcpy version: 1.17
• installation method: brew
• device model: Pixel 3a XL
• Android version: 11

Describe the bug
--stay-awake doesn't appear to be working for me. After whatever display timeout period, the screen goes black and I can't get it to come back on again. I can however close the scrcpy window and re-open and the screen will display fine again.

I'm running a Pixel3aXL running Android 11

Here's the command I use to launch scrcpy

scrcpy -s $ADB_DEVICE $ADB_PORT --show-touches --stay-awake --encoder 'c2.android.avc.encoder'

using device: 04QAX0NRLM, port: -p 17947

The option only works when the device is plugged in:
https://github.com/Genymobile/scrcpy#stay-awake

(this is a limitation of the Android option)

Thanks for the quick feedback!

This device is plugged-in.. direct USB

If you're looking at that -s and PORT line in my command - I have a script that will list all of the connected devices via adb and let me select which one to mirror. It does work with connected and wireless devices - but this device is usb

scrcpy -s $ADB_DEVICE $ADB_PORT

[jpage4500]

FWIW -- here's the full script I use in case it'll benefit anyone else too.. I often have several devices connected so it'll prompt me which one to mirror. Let me know if you see any issues with how I'm running scrcpy.. I'm unsure about the encoding param - don't remember what caused me to try that. I think due to some really laggy starts at one point.

screenMirror.sh

    if [ $NUM_DEVICES -eq 0 ]; then

The feature --stay-awake basically changes an Android setting. You can do it manually without scrcpy.

Read the value:

adb shell settings get global stay_on_while_plugged_in

Write the value:

adb shell settings put global stay_on_while_plugged_in 7  # enable
adb shell settings put global stay_on_while_plugged_in 0  # disable

[jpage4500]

I see.. the developer 'stay awake while charging' setting. I guess I could just call those commands before and after running scrcpy.. I'll give that a try

thanks

[rom1v]

I guess I could just call those commands before and after running scrcpy

scrcpy calls them if you pass --stay-awake. Check the value while scrcpy is running.

--stay-awake also fails on my Oneplus 8 Pro on Android 12, if I try the ADB command from above:

adb shell settings put global stay_on_while_plugged_in 7

Then I get:

Setting "Disable Permission Monitoring" (developer option) works for me on OnePlus 8 PRO on Android 12.

Now the ADB shell commands no longer fail either.

Setting "Disable Permission Monitoring" (developer option) works for me on OnePlus 8 PRO on Android 12.

It is effective for my OnePlus 13. After using the USB connect OnePlus debug, then disconnect the USB Connect and use it to use WiFi Connect.

Disable Permission Monitoring

still getting error on android 12 even after disabling permission monitoring
I am connecting wirelessly, using ethernally wrapper on top of scrcpy
