Hello I just replaced screen (obviously ordered from ifixit). On first test everything worked before reassemble. Later assembly done I turned on device and touch didn’t work. After hard restart it worked. But didn’t fix issue. Something after restart worked. Like 3 out of 1 time. What is the problem?

Its not an iPhone 6 or 6 plus is it? If its the 7 Plus which I think you selected as the device, try making sure you have the screens cables fully connected. Sounds like a silly thing to miss but on the iPhone 7/Plus I found multiple times I didn’t snap it in all the way onto the board which caused issues!
