I have this phone. I have 3 apps loaded that go on the internal with maybe 70mb used. My phone is full. I have an sd card that other apps go on. When I check the internal storage is says there are 92 apps installed. this is a straight talk phone. Is there a way to wipe out all the memory and start over without making it unfunctional with straight talk? Also, on a side note, this phone keeps randomly deleting apps. is the there a way to stop it from doing that? Thanks.
