Here’s what you got to do: Go to amazon and buy this screen.....
I can personally assure you this is a quality screen because I’ve replaced over 25 iPhone 6 screens and I purchase from this seller every time and have always gotten high quality screens.
Also this seller is very good because the tools that it comes with are actually pretty decent. I have bought my own tools at this point that are very high quality but considering you’ll only be doing this once these tools should be efficient enough to do the job.
In the end this is definitely a must buy screen replacement because it is good quality, comes with above average tools, and it comes with a glass screen protector as well
