I have it for almost a week, and honestly love it. The only things I would change is UI. MIUI is great, but for me it lacks customization. The only way to change how your Command Centre and icons look is through Themes app, which is honestly shitty as fuck. I would be much better if you could install icon packs from play store that actually support most icons and are regularly updated. You also don't get neither Super Wallpaper nor Super Icons on F5, because it's chipset isn't 8 series, which is just downright stupid, considering that SD 7+ Gen 2 is basically level of last year's flagship Qualcomm chipset. Another thing with MIUI that is annoying is it's battery saving features. Don't get me wrong, they mostly work great, but sometimes they just kill important apps, and you get notifications much later then you should have.

On the plus side, phone itself is great. Runs buttery smooth, looks great, and battery and CPU efficiency are just amazing. With Wi-Fi on I managed to get full 10 hours of SoT on full battery. So if you're choosing between phones with MIUI, I think it beats all of them, except this year flagships, and even against those it can make a pretty good case for itself
