I'm developing an app on Android Studio. Since a couple of days, as soon as I connect my Xiaomi 8 for debugging purposes the log gets flooded with random character messages from a package named "?" even if it's set up as "Show only selected application".
The logged text is always a combination of replacement character and random prints like this:
�k�#r
�|.
The pattern changes when I reboot the phone and it usually comes right after system messages like this:
? D/SignalClusterView: updateMobileTypeImage 0
?pV����.
? D/NetworkController.MobileSignalController(1): 4G level = 2
?pV����.
? W/swapper/4: type=1400 audit(0.0:2480): avc: denied { kill } for capability=5 scontext=u:r:kernel:s0 tcontext=u:r:kernel:s0 tclass=capability permissive=0
?pV����.
? D/SignalClusterView: updateMobileTypeImage 0
?pV����.
?pV����.
.
What is causing this? How can I stop this behaviour? Is everything broken? Thank you in advance!
