Also doesn't work for me and my friends phones, I use a S9+, they use a S21. Just got myself a Q3S, and was excited to mess around, but now I have an expensive brick :D
Well, you don't have an expensive brick, you have old phones. 😂 OK, seriously now, there is definitely a problem with the Horizon Android phone app.. I've the latest Android 16, and though it works it's buggy for me. Wait and hopefully they'll update it shortly.. I hear that the iPhone app is ok, if you have a friend with one, you could try it. I did factory reset recently and even with the buggy app it updated on Android 16° . Btw, I'm very impressed that you're keeping an S9+ going! I had a Note10+ for 6 years before it slowed down too much and had to upgrade. The S25 Ultra is a good option for you for the future if you want to stay with Samsung. The iPhone of course is another good option! Anyways, I hope you get it fixed soon. ☘️☘️🤞
