I installed Chrome and it is no longer doing it.
Mine recently started doing this also and it is frequent.... And now the latest update messed up my individual ringtones which I rely on to know who is calling without looking at the screen. The Phone also lags. I hate to admit it but I think this phone has been a disappointment
Until there's flash, no love from me

For what its worth "First we have heard of this problem" are famous lines from Sprint tech supportI'm sure they are getting a ton of calls on this.
