The chances are that OnePlus will deny to repair your phone though. By repairing your phone they have to guarantee the working of the replaced part, which in case of water damage is really unpredictable. After water damage every device could die any minute, technically. Most brands refuse to replace anything on water damaged devices.

It would be great to have a clear photo of the iPhone without LCD as you did with some previous models. It makes a really great wallpaper. Thanks in advance!
