Re: Horrible apple replacements
With my 6s plus when I install the screen protector glass the adhesive on the temperglass touch the Touch ID sensor causing it to act up on my iPhone 7 I let Apple install for me
So it seems to be a recurring thing with you where you are the cause for the phone not working. Getting water on the battery case which probably caused the issues with your 7 and messing up your touch ID on the 6s. I mean if you have to return 2 phones a combined 11 times (which you claimed between your 6s and the 7) there is something you are doing wrong, especially with it being apple and not some bargain bin Chinese OEM.
