@manual_v - we posted the solution in other topics, I will repeat it here and then close and archive this topic to prevent duplicated forum topics.
This seems to be a compatibility issue between 1.6 and 1.8.
You can resolve this by doing the following:
Go to your system settings
Tap on the Apps icon
Go to the ‘All’ tab (you can see the tab option at the top of the screen)
Search for the ‘Media Storage’ icon and tap on it
Tap on the ‘Clear data’ option
Sorry the update caused so many issues for you
