S21 sm-991u1 have n78 band.
I can use 3,5Ghz band with this phone.
Phone is getting warm as soon as I turn on my data, when WiFi is on, no problem, battery life could have been better, other than that, a very nice phone to have.
Have this phone for almost 2 years now and still love it.
Aqib, 16 Aug 2023Yes, it is happening in Note 20 and S 20 series. there is no report in s21 seriesI have seen many display issues in s21 series, specially in ultra & 21+ (In Bangladesh Samsung user community)
Hassi, 15 Aug 2023No dear there is no heating issue in this device. I'have been playing pubg very frequen... moreIt does heat up if you play for like an hour straight but just put like a damp rag on it or something and it will be good in no time
5 hour battery life is not that impresive especialky for lightweight apps such as whatsapp, tiktok, youtube, etc. Playing games like roblox can get warm really easily
2 years with this device and still running like a new phone! But the ghost display has been showed.

Im will never buy a Samsung phone again.
So first impressions, love the phone design, small and compact. Battery is good enough to get you through the day. Phone gets really hot to the touch when performing somewhat demanding tasks. Gaming performance is nice.
I had my one ui update a week ago and I have no problems.
Anyone getting slower WiFi speeds since the last update?
Heard a couple of comments on samsung forum that s21 has started experiencing this also. Anyone can deny or confirm this ?
