  4. For the instance Google Play store looks like it is downloading an app, but then you get a message that the app was not installed due to insufficient space and you are sure you do actually have enough space– I cleared the cache, turned off the phone, opened it up and removed the battery and sim card, waited approximately two minutes or so, reinstalled the battery and sim card. Restarted the phone and went back into the Google Play store and it downloaded and installed apps without a problem. This has happened at least twice and each time this method worked for me. If you are going to take out the battery, make sure your phone contacts are saved to the SIM card as well as any pictures or videos backed up or saved in the cloud (just in case).
