It's usually when I'm browsing the Chrome app. If I'm in it for more than a couple minutes, app in the background like Pandora or PVSTAR+ are killed without warning. Also, when I leave Chrome, app icons are slow to load/open, and the app menu is slow to open. I'm not sure Chrome is the reason for this but it is the most memory intensive apps on the phone
I searched the problem and one of the solutions I read was to do a factory reset because one of the apps may have been a bad install or something. When I did this, it seemed to work at first, but the problem just came back later in the same day.
I've had the phone since the end of 2012, but this problem has just started in the past few months
EDIT: I actually had it replaced during the summer due to SIM card issues
