Hi,

I own a Mate 7 Gold Dual Sim and after the replacement of my screen, It seems the sim olding the data can't hang the network very well.

Any idea of what to check inside? Maybe the antenna but I don't find anything about it and where it is inside.

By the way when replacing the screen, be carefull to unplug the ear speaker on one piece cause it's really hard to get it.

Thanks for your help,
