Hey @tsagatakg. What is not working with the Ring app? If you do not have the app downloaded from the Google Play store or the Apple App Store, it may not function as it should as these are supported app platforms. Let me know what seems to not be working with some more details and I'm happy to help out further!
Hey neighbors! I recently helped out another neighbor with the same type of phone here. If you go to this post, it details some of the limitations that the Huawei phone has. Please note that if you do not have the Google Play store on your phone and cannot get the Ring app downloaded from there, this may pose some concerns with the app behaving as it should. Downloads of the Ring app are only supported via the Google play store, Microsoft store (for Windows computers desktop app), and the Apple App Store. You can learn more about this on our help page here.
