App permission problems. I cant click on allow.

[AC Question]

For example when i open the Hangouts app to send a picture it asks for a permission to access the camera. I can't click on allow. I can only click on deny. To allow the app permission i have to go to settings and do the long procedure. Please help me.

to proceed, use only android 3.5 devices

1. android 6.0+ devices may cause system permission error like screen recorder or gallery vault or files backing up in your computer connected to your android device with USB

2. remove ALL accounts and re-add them again twice

3. uninstall and reinstall system updates

that's it! enjoy!

Same problem with Huawei P9 Lite after upgrading to 7.0
Deinstalled the otherwise very reliable ES File Explorer - problem solved!

Thank you! My husband had the same issue on his P9 Lite, and I've had this nagging feeling it was ES File Explorer, and now that he has finally removed it, it's working perfectly!

pp permission problems. I cant click on allow.

If you have a
Navigation Bar app
Uninstaling it may be helpful
Its because the app has screen overlay permission and that could make the problem
And i personally think that the Android OS isnt sure of the safety of tapping allow when there is a screen overlay on it (other apps that require screen overlay permission may display other button on top of the give permisson message and do something else by pressing allow on it and could be malware or other stuff.) but mostly its a Screen dimmer app or as i said it also could be a Navigation Bar app.
And updates on some phones may also cause the problem as others here are saying
If its a screen dimmer app you can just disable the dim (not the whole app) just open the screen dimmer app (or if it has a notification where you can do it) just turn the dim off and then press the allow button.
