Six month before i brought htc 628 dual mobile, from the date i am so facing lot of errors and network issues. Dual sim software not working properly, many times mobile internet disconnected automatically after i must restart the devise.
While brought this mobile android V 5.1, still htc won't give any update. i wasted 15000 Rupees. Date by date i loosing trust about htc mobiles and i stop suggesting htc mobiles to my friends.
HTC is have repose to give android version update and must fix problems.
