This is short video explaining how to repair your broken screen on a iPhone 6 or 6s. Its a pretty easy repair that you can easily do your self, with quality parts purchased on for example www.iPhonereparasjonkristiansand.no
I have been repairing phones and tablets for over 10 years, and also run my own repair shop.
The only thing you need to watch out for is the home button flex, that is quite fragile, and needs to be moved gently.
Luckily the replacement parts are cheap, should there be any mistakes made.
