I've had the Epic for a month now and the lag with the physical keyboard is really starting to bug me. It's especially bad when you need to text words with a double letter like "cool" for example. Is there anything I can do to adjust this? Or fix this? It's very frustrating. I used my sister's HTC Shift and her physical keyboard does not lag, why does the Epic? I'm past my 30 day trial with Sprint so I'm at a loss for what to do. HELP!
