I had my iPhone 12 Pro Max screen fix by then on Saturday and I paid £60 for it then with in about 1 hour the screen started to flick and then I tuck it back to him and they said it’s normal it will work probably just let it settle in and then it did then with in 1 day my screen going black and will not turn back on I went there today to explain to them and they said I had to pay a anther £60 to get a new screen put on my phone so no way
