BE CAREFUL WITH CUSTOM SCREWS!!
I think it is a huge design mistake by nothing - you can literally screw into the display from the back! There is no metal or security mechanism - I designed a part and used a longer screw for a good fit and did break the display - not just the glas - the electronic, so nothing 😉 is working anymore and I had to replace it.
I didn’t use much pressure and force, I did screw up some electrical devices before. It could have been prevented by designing the phone - which is made for custom parts and screwing it up - by just don’t letting the screwhole going through.
So be careful and measure your screws exactly!
