It stays on the pairing screen. Please help troubleshoot! I’ve reached out to customer service and gotten no response and I’ve reached out on your YouTube account as well. ### 1/5 — app *2025-12-02, version 2.3.4* it wouldn’t connect to the case even when the case in on my phone ### 1/5 — CONNECTIVITY ISSUES *2025-11-05, version 2.3.2* I’ve had the case for one week and was stoked. I’m not too clumsy so the case hasn’t been through too much wear and tear. Yet, after one week it won’t accept any new images and will not connect. I’ve tried charging phone fully and reapplying case but still nothing. Great idea, but needs a lot of work. ### 1/5 — Having trouble with verification code *2025-10-21, version 2.3.2* Just got a case, trying to login when it asks me to type in a verification code using my phone number. It doesn’t take 10digit numbers so I add a 1 to the front and still doesn’t work. If anyone knows how to fix this please let me know ## Most praised reviews (10 highest-rated) ### 5/5 — Great app and phone case *2026-07-08, version 3.2.3* Super intuitive App which works great to put anything I want on the xtrem case. I’ve noticed a trick that sometimes when you’re uploading and it doesn’t always connect, lift the top right of the phone case a little bit and it will connect and start uploading the photo. ### 5/5 — Super happy with it！ *2026-06-11, version 3.1.5* New update is so fun😍 Looking to more coming！ ### 5/5 — Magical! *2026-06-11, version 3.1.5* Really love this case!

Please add invert and fill the background color option for then the image is too big and one has to shrink it. ### 4/5 — Good app with color issues *2026-07-20, version 3.2.4* When I use the app every single tone of blue ends up as gray, even purples or like sky color. Green also looks like yellow.

There is red and yellow. The images don’t come out quite nice. Also the transfer rate when I first got it was super fast, but these updates have failed and don’t really transfer. Sometimes you get stuck at 30 or at 80%. I don’t know what happened with this latest update but I’m kind of messed up the transfer.
