I have had to purchase a replacement bracket and screws for the home button on the iPhone 7. On the iFixit guide, it says that there are 3x 1.3mm screws and 1x 1.1mm screw. However, with the parts I’ve purchased, I can’t distinguish between the different sized screws. And no, I do not have any callipers to measure the screws. Any advice would be much appreciated. Thanks.
If you have a magnifying glass, try to compare them under it. Since you know you have 3 1.3mm screws and only 1 1.1mm screw, compare them to each other, and pick out the smallest one. the smallest one, is your 1.1mm.
if you cant distinguish the smaller one for the homebutton don’t worry, just put that one in finger tight.
