i have the 4g variant with 6 gb ram for like 4 or 5 months maybe and I didn't had any problem with the phone. its super fast, the camera is not the best but its a decent one, for example instagram posts etc... the phone looks very premium and you will impress your friends and all when they will see it, i guarantee you. but keep in mind this phone its from 2018 so no more android version updates, and we don't know if it will get android 11 or not, but at least the android 10 with miui 11/12 has a lot to offer.
