"This is not Xperia Z3
This is a guide of the M4 Aqua" - Faruk
Just thought it could be told in english as well, cheerio!
I really liked this guide but what i did not like was that it did not show how to remove the metal part from the screen, nor the speaker and camera. If possible please add this! Otherwise great guide as usual on ifixit!
This is not even close to how you do it. This is just a small part of it, this video leaves out the part where EVERYTHING comes out with the screen, its just the backcover which is removed when you open it up. you need to remove, the battery, sim-tray, motherboard, daughterboard and the speaker to be able to remove the screen. This video is misguiding. It is VERY hard to replace this screen, do not try it if you are not very experienced with mobile repair.
