[Sony Xperia XZs Questions & Answers] vgamesx1:
Alright well great news for you and anyone looking for replacement screens, I'm not guaranteeing anything but the XZ and XZs do appear to share the same screen, it totally works! (Pics below)

One thing to note, my screen didn't come with any dust filters and it's probably a good idea to replace the adhesive for the earpiece when transferring it over, but I didn't have either of those so I just took em off the broken screen.

Edit: Update, I just got some adhesive for my phone so the screen will stay securely in place, I was previously using electrical tape as a temporary solution which does alright but I can't recommend doing it, as it leaves sticky residue behind which takes a little more effort than I'd like in order to remove it, if anyone needs the adhesive and doesn't mind waiting 2-4 weeks, I can recommend this seller KevinTwoPlusOne Store because you can order 3 pcs for $1 which I highly recommend doing since if like me, this isn't something you do often then there's a good chance you'll screw up on your first try making extras mandatory, also I'd like to note that the adhesive isn't as strong as OEM, the screen can be pealed off again without heat, now that doesn't necessarily mean it's less effective at keeping water out but I'm obviously very hesitant to test out whether my new phone is water-resistant or not, especially with the reused adhesive around the speaker.

Edit2: Alright well 4 months later I have another update, the adhesive I recommended a while back is starting to give, after normal use and a few mild drops I can see a small amount of light from the backlight from under the left corner, I admit I may have messed up applying it in some way, but I might suggest paying a little more than $1 for something better or just use some double sided tape.

Edit3: Ok so I made the dumb decision to buy the same adhesive a second time and it appears that my issue had more to do with my phone specifically, as I applied adhesive again and it started to peel up in the same corner within just a few days so I took it off and this time I noticed that my screen doesn't quite sit flush except in one small spot, so possibly even a bad design for the frame? I dunno, it doesn't appear to be bent or anything but I applied the adhesive for a third time and it looks like it should be flush and should hold pretty well now, so if you want to save a few bucks it's not a bad option, it shouldn't be any worse than double sided tape however, I'm going to have to standby my previous statement and recommend just paying for something stronger, it'll just be less of a hassle later on AND make sure you place your screen into the frame a few times to make sure it sits flush, that said definitely still get some cheap stuff so you can practice it a few times before you try with something stronger. (just found out that this is actually a fairly common problem with xperia phones in particular the Z3 compact where the third-party adhesives don't hold, you need something on the level of OEM quality and not OEM compliant.)

Edit4: Alright this should be my final edit and I've come to the conclusion that none of the currently available adhesive stickers are strong enough to permanently hold the screen to the frame, if a HMG sticker comes along then maybe, but until then I'm going to recommend using B7000 instead, it's cheap and the main thing most people are recommending to use, I've also heard some good things about loctite vinyl adhesive but it'll cost a little more per oz/ml so something to consider if you run a repair shop.
