Help gyroscope doesn't work correctly

[moh3enkimia]

Hi, my gyro sensor doesn't work correctly after update to android 5.1.1. I can rotate screen but I can't take 360° photos by google camera app, and even I can't see 360° videos and photos on my HUAWEI G7, and I can't use my cardboard anymore. I was using it without any problems before update . Help me

Could try a factory reset, just in case it's something funky going on after the update.

Before you go through the process of a Factory Reset, try wiping the system cache partition. The system cache is its own partition, separate from the general user partition so it won't affect any of your data. Clearing the system cache after a system update is generally a good idea anyway. You need to reboot your phone into Recovery Mode to access the 'wipe cache partition' option:

Another thing to try is install the 'GPS Status & Toolbox' app from Google Play. In its options menu there are 'Compass calibration', 'Calibrate pitch and roll', and 'Manage A-GPS state' selections you should run.

Thank you, But I couldn't access to my bootloader because it was locked. And I did your second way but it did not work.
And even I did factory reset but did not work. What do u think guys? I could use gyro before android update, Is it a bug? :-\
And how can I access to my phone's bootloader?

In the GPS Status app, in the 'Diagnose sensors' menu options does Gyroscope have a green checkmark by it or is it a red mark?

The selection to wipe the system cache partition is in the same menu as the Factory Reset option.

Unlocking your bootloader is a different process:
