Metro Pcs. Samsung 920 4G. Working fine until Nov, after airplane mode not longer capable of staying connected to network. If restarted it will work for less than 5 minutes. I'm able to connect to the WI at home or elsewhere is just the Metro Network. All I gotten from Metro is the run around. I have taken it to Metro more than once> reset it in 3 occasions, Called Samsung the equipment is OK. What can I do? of course Metro wants me to buy a new phone.If I restart the phone it works for maybe less than 3 minutes. No access to email, or any applications requiring an internet connection.
