Chosen Solution

Everytime I try to play my games or use my apps and my internet my phone locks itself it has already locked itself 8 times while trying to ask this messaging and calls work fine but it always locks by itself when I try to do anything else I use the pattern lock screen and I have a 32 GB SD card I don’t understand why it keeps locking

I have the same problem. My phone will load an app, then kick me to the lock screen. Please help. I’m using a tracfone Alcatel one touch. The only error I’ve seen, was my phone telling me to insert the sim card…..Is this related?
