I'm having problems installing apps?
After a software update, I keep getting an error message when I try to install new apps.
Probably an app you are trying to install is not compatible with your new software update. For now, the best thing you can do is to leave a comment about your problem on the app page in the playstore and wait till the new version of the app compatible with your software will be released.
Or if you really need that app, you can just roll back the update, so the old apps will have no problems installing and running.
