Hey, so it turned out it was one of the easiest screen replacements I had ever done actually. Mainly I heated up the front screen and worked a thin guitar pick under the screen like any other phone. Now be careful here the ribbon is connected to the motherboard and held in place by a small strip of metal. And you'll also see a full metal sheet holding and covering the whole insides. So just un screw the 2 screws holding the metal piece to the ribbon and disconnect. That's it. Obviously reverse the steps and what not and you've replaced the screen for the ulefone power armor 16 pro.
And I believe it's pretty much the same for all Ulefone armor and power armor models. But I'm not a 100% tho. So good luck on the repair.
