Piece of cake after all

My Problem

Screen has lines running on it, tells me the connection of the display module has problem

My Fix

Perfect, iSlack is useful but still need help

My Advice

Its very tight for iSlack to open in first trial, you need to still use the suction cup a bit, but be careful not to be too 'excited' on the opening process, once it shows movement, switch back to iSlack to prevent killing your precious Touch ID
