Android tech questions eg: Galaxy s5
Hi, just wondering if anyone could tell me a number of things about Android and the data that it keeps on the phone. I have a galaxy s5 and have deleted text messages and pics over time and wonder how long I have to recover them. The phone has told me that it is full a number of times, does this mean it is overriding the deleted data or does the phone have two sections for these purposes? Also I had a kik account that I deleted the whole app, does the phone hold any old messages or contacts? I have reinstalled the app a couple of times under different accounts, would that override the data from before? Also pictures, how long will the phone keep deleted pictures? I haven't been able to root the phone as of yet but in particular want to try and recover the kik contacts and messages and also the Facebook messenger app details that I had on there, I have also deleted that app and reinstalled it later under a new account. How long does the phone keep data that has been deleted from a heavily used phone?
