Will try to separate things a bit now, to get a better overview on things. As this is rather generic fixes, it might not cover every little bit, but is to be seen as a starting point.
Restart your phone
Yes, as simple as that. Just restart your phone. It’s always the very first thing you do. If something behaves “strange”, you always restart first. Since sometimes that WILL help. And, it’s easy to do.
Having issues with USB OTG after an update?
I’ve seen that some gets helped by wiping the cache partition on there phone, possible with the help of a factory reset as well.
Phone refuses to take a screenshot, “Couldn’t capture screenshot: Storage may be in use”
1. Restart the phone, it works for most
2. Wipe cache partition. It works for the rest.
3. You actually have an app, or something installed that do prevent this.
1 is the most common fix I’ve seen working for this.
Camera refuse to start despite cache/data cleared for the Camera app
Seen this work on Desire 816/826/etc. Simply wipe the cache partition and the camera should work again. If it doesn’t: there’s other things as well.
Specific app that’s misbehaving
This can help for most app related things. Just go to
Settings > Apps > All > [Name of app], there you have:
- Force stop, will force the app to stop running if it. Can be useful if it behaves badly.
- Clear data, this clears ALL data used by the app. Like user settings etc. Can be VERY useful. Do know that user settings is removed by doing this.
- Clear cache, this clears up temporary data used by the app. Shouldn’t remove user settings etc in the app. Also very useful.
Google Play Store refuses to install or update apps
Step 1 is to clear cache in both Google Play Store and Google Play Services.
Settings > Apps > All > Google play store, Clear Data and Clear cache
Settings > Apps > All > Google Play Services, Clear cache. and Manage space, Clear all data
Still not working? remove your google account by going to Settings > Accounts & sync > Google, where you tap the 3 dots after your account address and there you select Remove. To add it back simply tap the + sign on the upper part of the Accounts & Sync page.
Temporary issues there: Unistall updates, but those two steps before usually fixes things.
Facebook Messenger (and other Facebook apps) that misbehaves on a Lollipop phone
Lags etc , this is helpful on a Nexus as well.
Disable Nuplayer under Developer options. More on that HERE
Phone behaves badly after update
This I tend to see around all updates, which tends to be sorted out by a factory reset. Possibly wiping cache partition as well. It’s the factory reset which gives you the most “bang for the buck”.
