Fair enough mate, sometimes it can be a software issue with apps, if you've already got it it might be worth checking. Else it's a hardware issue then a new device is needed lol 👍
Best of luck 👍
If the app isn't available from the app store, you can download the apk file online and install it that way, it might work even though your phone isn't supported
