Xolo ERA 2X is average in Sound Quality. Its Black Screen is Amazing You Can’t Differ Between its Screen and Outer Area when screen is off. But a problem that is curse for Human mankind is that this phone Stops receiving Data from Wifi After Several minutes of use, Many Times I use Reboot device But the problem Doesn’t Solve. I think this bug Is need To Be fixed. Camera is literally Worst. Although This Phone Doesn’t Have any Hang Problem. I think this phone is not Meant to Be buy with this availing price.
