question too vague
All of a sudden today, I am getting continuous requests for Android System UID asking for root permission. I deny/fail to grant, but minutes later, it happens again. What is it? What should I do?
are you s-off? rooted? what superuser app are you using? custom rom or stock? logcat? Your question is too open-ended for a real answer.
with that said, here are some shot-in-the-dark type answers, try them at your own discretion, I'm not liable for what you choose to do.
If you have a custom recovery, try rebooting to recovery and wiping cache/dalvik...fix permissions. Reboot to system.:fingers-crossed:
(this would be my first step)
open your superuser app and update binary and/or reinstall and/or switch apps
The Android System UI needs root permissions, but it shouldn't be asking for it, it should be part of the code. I personally would not deny my UI, aka User Interface any root permissions. Try granting and see what happens.
