I have a "used" HTC Desire 310 with a Vodafone version of Android running on it. Just recently it has started restarting everytime I use it for Texts or Phone calls. I open a Text, read it and then before I can do anything the phone restarts. With calls, at least it waits until the call is finished then it restarts. It is only a recent occurrence and I assume is to do with an update, but how do I work out which one?
