Chosen Solution

Hi all I bought a IPhone 6s cheap as it was bent( trapped in car door) previous owner said it was work like that until it got dropped again. So I got an new screen and housing and changed all the parts over. Now I have a intermittent unresponsive touch screen. No sound, vibrate or front or back camera or flash, it seems to charge ok and can receive calls. Any ideas would be appreciated. Thank you

If the logic board was bent, you may have all kinds of issues. All it takes are a few broken solder connections here and there and you could be chasing problems for a long time. Your problems don’t seem related either so a single root cause is unlikely (other than the original bend and subsequent drop). I’m not convinced the previous owner has been straight up with you. This probably needs to be looked at by a micro-solderer but, sadly, I wouldn’t expect any miracles on this device.
