Hello all.

i found out that the problem was caused by the LCD screen installed. The LCDs for the G935A, G935V and G935P has different sub PBA from that of the normal G935F LCDs.

Changing to the proper LCD assembly solved my problem.

Thanks.

Unhappy Samsung Galaxy S7 Sprint MIPI DEVICE FAIL.

Hello everyone,

I'm facing an issue with my S7 sprint. That all the mobile network is gone It suddenly started saying searching for networks. I tried to switch automatic mode to GSM/UMTS
But it is stuck on Automatic.

After dialing *#0011# In service mode everything seems fine except it says Non-fatal MIPI device fail.


Please guys help me. Please tell me a solution.

And restarts sometimes
