Why do screens keep separating
I have recently started an iphone screen repair business,. I'm having problems finding a supplier based on the fact that I don't need to buy screens in large numbers at the moment so am buying screens from ebay.
I only buy good quality screens from users who have sold thousands of units, I make sure I am buying 100% brand new and tested. But.... I've had a couple of incidents where I've fitted a screen and then within a short time period I've been called back because the screen has started to 'lift' away from the LCD, when this happens I have to replace the screen free.
Is it just bad luck and does this sometimes happen, is it poor qualify screen (even though I believe I'm buying good quality) or is there some other factor.
Advise from more experience repairers would be great and even recommendations on reputable sellers of screens. I don't want to get disheartened so early on but it's getting annoying because I think I'm doing everything right and then things like this crop up.
Is this a good question?
