Lenovo M10 HD flashes black screen before and after login

2021-02-17, 2:56 AM

If anyone else notices this issue after your M10 HD has a fresh install, then updates apps and starts flashing a black screen just after you login to the device the solution is this: set your screen lock to none, restart your device, then enable your screen lock again and the black screen flash should disappear and the home screen should load right up. Took me forever to find this fix.

 

If you check the Notifications Log the com.tbsmart.levision will be giving you a Null notification. After resetting the screen lock options the Null value error notification for Levision will no longer appear  and the home screen crash will have been fixed. FYI this problem also occurs after setting up Facial Recognition.

After turning on facial recognition I've found the home screen crashes again so currently there seems to be a problem with FR and Levision. Turning off facial recognition is the only solution for now I guess.

Levision is the culprit and seems to be the Lenovo's facial recognition app causing the black screen UI crash on login. Android 10 FR isn't native so Levision is bugged since one of Androids latest update.
