The phone stopped working?

The phone first few days complained about the memory. I cleaned (was free about 250 megabajtov memory on my phone is less than 4 gigs, so I normally released). Everything was fine, only occasionally pop out, the memory is full, make room; when I watched YouTube or call. Sharply today programs began to use Android trainer for running, first the google play services, then SMS, etc., in the end the phone started off, pulled the battery to no avail, the phone worked for 10 seconds and off, then worked a minute with the locked screen, but as soon as I put the music on, it went off again. Now it works, but programs continue to use Android trainer for running, with which it can be associated how to solve?
PS Sorry for the bad problem description, I'm no expert

Pick up the phone and go to the specialist who will examine it and say what it is. You will likely need a firmware or hardreset. But there is already speculation and guesswork. The hike in service to a good master, will be the best solution.

If after cleaning the 250 MB of the 4 GB of RAM, it is critically low for the phone. You need to have at least 25% of RAM. Too many programs installed.These programs work in the background and clogging up the memory. Save your data and contacts, do a factory data reset and do not install different stuff on the phone.
