My Optimus T runs terrifically! That is, except when I turn on Wi-Fi. I first did this in order to enable Wi-Fi calling, and noticed that apps took a lot longer to open, and sliding from one home page to the next looked choppy. So it seems that having Wi-Fi turned on (I get the same behavior whether or not Wi-Fi calling is turned on) is using the processor too much. Is this normal? Can you tell me what's going on and how to fix it? Thanks.
