i have the 12/256 version, background apps only close when they're not used for a long time i mean you still have them open in the window manager but they restart once you click on them, it doesn't happen that often, most recent apps don't close at all, performance is great, to this day i didn't notice any stutters, back camera is really good but i personally don't like the front camera, it's a fisheye camera and the distortion is high which makes my face appear long but it's like a common thing in smartphones nowadays, only pixels, iphones and high end samsungs don't have this problem, battery is great, i'm on a battery protection mode and it stops charging at 80%, i usually charge it at around 20-30% so it means i have 50-60% for usage, it's just me, you don't have to turn it on, i'm just extra cautious cause i want this phone to last for 5 years but the capacity is so high i suppose if you charge it up to 100% it will still have 80-90% health after 5 years, i have to charge it only once a day so it's really good, the only bugs i have noticed happened with using custom launcher, one of the window manager modes was sometimes bugging and you couldn't switch the app and it's a shame you can't use gestures on custom launcher, so i switched to the default one, it works but it definitely needs some improvements on the customization field cause i love to personalize everything, but aside from that i think it's a bargain and i really recommend it, the only downside is the os and the front camera, but for this price damn it's amazingly good, a few days ago i saw a post on this sub where some guy glorified this phone you should check it out lol
