I recommend using b7000, ( you can use it with what ever adhesive you currently use , make sure you clap or tape the screen down for 30 min so the b7000 can seal to the screen n frame) Also you do not need to use allot this is strong liquid adhesive that drys fast. Good luck

Hello so I also had experienced almost the same issues with the iphone 7 plus ,until I started to buy higher quality aftermarket iPhone 7 plus screen. When purchasing iphone screens please remember that there is many different qualities out there. When buying aftermarket screens I suggest buying Tianma displays , I have had barely any issues with these displays. FastFixCell.
