With the recent update on my LGV10 software I now notice the phone constantly searching for a 4G signal. Phone alternates from 1x to 3G in areas were I use to get a 4G signal. The phone heats up and the battery drains constantly due to this signal searching. I have tried restarting the phone, removing the sim card. The phone does find the 4G for a brief moment when it is restarted but goes back to constantly searching for the signal under 3G. Please Help!!
