Touch Issues after screen replacement discussion
I have been fixing phones as a side business for around 6 years now, starting with the iPhone 4. I have used a wide variety of replacement parts from multiple vendors to try and streamline the order and repair process of the business. Ive used both aftermarket and original screens (refurbished with original lcd) based on what the budget was for the customer. With everything, there are issues with parts from time to time and sometimes in batches. The main reason for the question/discussion is that I have a very high failure rate with 7 and 7 plus replacement parts. I hardly ever have any issues with the original screens. I will have at least a 10% failure rate. I have tried multiple vendors from iFixit to Mobile Defenders and have the same problems. Does anyone else seem to have a higher than normal failure rate with the 7 and 7 plus? I feel like at this point it's a manufacturing issue, but I never go a full month without having at least 1 bad 7/7 plus have touch issues. I have used aftermarket parts before on other iPhone models with little issues. The 7 and 7 plus models are excessive enough to where Im about to stop offering a cheaper alternative and just use original.
