Some FAQ's on Android Pie Release

Q. Why is my brightness low after upgrading to Android Pie 9.0?

A: Google introduced new algorithm for the brightness which will give more control to the user specially in darker environments. The user have to train the brightness preferences for some time in different lighting conditions they use their device so that the device learns it and then adjusts the brightness automatically after that.

Q. Where is clear Cache in Android Pie?

Q. Why is my battery draining so fast after update?

Q. I do not like the new Recents layout, what can i do?

A: Unfortunately, nothing can be done about it. Its how Google designed it.

Q. My Play Store is showing "uncertified" after i downgraded to stable, how can i solve it?

A: Clear Google Play Services data and Play store data and Reboot. Let Play store update automatically and it should change the status to Certified.

Q. Why cannot i use volume buttons to control the ringtone volume in Android Pie?

A. Google has made change to it, now we can change media volume by default. OnePlus has provided a shortcut to directly go into settings to make it easier to change the ringtone volume.

Q. Why my Fingerprint does not work, after my phone is in standby for long time?

A: The Fingerprint service goes to sleep and thus doesn't allow unlocking the phone.

To avoid this, the current work-around it to turn Off Standby Optimization in Advanced Optimization Battery Settings or wake up the phone using Power button after long standby.

Q. Why does not my screen light-up on incoming calls?

A: This happens when the Phone app settings is messed up.

To solve this:

Touch and hold on Phone app and Tap on App Info.

Now tap on Notifications and then tap on Incoming Calls(Not the Checkbox).

Select Behavior and make sure its set to Make Sound and Popup on Screen

This should allow the incoming calls to notify you lighting up the screen.

Q. My clock shows alarm notification 2-hrs prior to actual alarm/ my alarm is missing, what can i do?

A: You can follow the steps below to fix it:

Go to Settings>Apps & notifications>Display all apps>Clock>Notifications.

Now, there are 2 things to do :

a) Press on "Clock" (Not the Checkbox)>Behaviour

Choose "Silent display" : this way you won't have the sound notification 2 hours before schedule

b) Press on "Alarm" (Not the Checkbox)>Behaviour

Choose "Sound alert and display on screen" : If you choose another option, the screen won't turn on when the alarm rings. And you also want to set the sound alert to none. Otherwise, when the alarm rings, you'll also hear the notification sound.

Q. Why is my slow-mo videos stuttering?

A: It seems to be a known bug currently. Developers are aware of the bug and are working on it. The fix could be released in future update.
