@humbl3one Hi, let me share my experience using UT on Redmi Note 7 as a daily driver for 2 months and counting as a 9 to 5 worker (WFH). But please note I have another phone for my office specific app only (iOS). I've been using all the basic functionalities and included apps without any problem. Default apps are so very useful and less bug. Although Redmi Note 7's fingerprint could result spamming "enter" on UT (can stop spamming by swiping the fingerprint reader again), it can be tricked by login using passcode instead.
App wise, I don't rely apps to anbox, as I think it's still buggy and UX-wise is so uncomfortable for me (laggy, inaccurate tap/touch location, etc). For email Dekko 2 covers my needs and less bugs. Thankfully, my office use Telegram groups, so I could abandon whatsapp and write "Contact me via telegram" in my whatsapp bio lmao and use the Teleports. Some social media apps I use is Instagraph (UI buggy if using SuruDark), Twitter web app (no play video support, but it's okay for me, could open via browser instead), Teleports. What I didn't try because I didn't use: MMS, Teleports calling (I guess it isn't available yet).
In conclussion, for me myself as a 9 to 5 worker I can live with UT phone as my primary phone. But because some requirements from the office I need to have at least another phone to be able to run their apps (can't opened in anbox so..). Also anbox is still not so stable imo and I can't make sure if banking apps or maybe your daily needs such as ride-hailing apps will work smoothly and less bugs (cuz they need fully functional Google Play Services), but if you also don't need them, or somehow Anbox covered them and having less bugs, I said you definitely could use UT phone as your only phone. Hope my experience helps. You could ask me anything too.
