Just got the Htc One last week,great phone. Love everything about it except it doesn't seem to hold a 4g signal even in known 4g areas. Tried the Optimus G for a week before getting the Htc One, and it held the 4g signal great in the same area the Htc One gets the 4g signal and drops it right away & goes back to the terrible Sprint 3g signal. Maybe the next HTC firmware update will help? Any ideas would be helpful. Its frustrating cause cant use the company wi fi at work & 4g signal is there just wont hold it like the Optimus G did, too bad cause Htc one is a better phone except for this one issue. Help???
