My apologies if this has already been discussed in a previous thread, but I tried to search and didn't see it mentioned... It seems here lately that whenever I turn on my 4G radio (I'm in a 4G area), my phone becomes very sluggish. Browsing and pinch-to-zoom using the Dolphin Browser becomes stuttered, swiping between home screens is delayed, pretty much anything I do is slower. I've killed all apps, but still get the same results. Once I turn the 4G off, the phone works fine. Just wondering if anyone else has run into this issue. It seems to be counter-productive to have a faster data speed when it makes your phone slower, basically canceling each other out. Any suggestions or feedback is greatly appreciated.
