Yup, it gets very hot when I hold on to the phone and have to resort to a casing. But now my Nilkin casing has a slight burn mark and I quickly send it to the service center (second time).

Can't remember the exact battery life left with Google Play Services in used, but it's usually between 40 to 50+%.

My phone has every little app except for the necessary one, I don't even play games on my phone.

1. Don't use multi window. - Basically during video call + browsing the net, my S10 never fails.

2. Activate Wifi Calling, off the sim card. You will still get calls if you use WIFI. This is to test if your modem having issue or reception is bad at your area so your phone keeps searching for base station. - Might try this after I collected my phone.

3. Remove all background apps. Especially the camera if on. Use the clear memory widget out of box to do it. - The phone is still moderately hot if I don't use video call, but this shouldn't happen as my old S10 never has this issue.

4. Are you using the phone while charging? - Nope, scare the phone will explode lol

Can try using the Samsung restart schedule, but if end up having to do that every time, I'm gonna switch phone.

Not sure why they didn't replace the modem, but the guy told me mine is basically a brand new phone coz it's a brand new screen, battery, motherboard.
So no one encounters this issue here? It is only applicable to S21?

HI there. Glad you can use cable connected Android auto with s21 ultra. I have no problem with wireless android auto with my wife's car but can't seem to connect using any cable with my car.

Can you explain what do you mean by Samsung original cable? Isn't the cable included in the box is type-c to type-c connector?

I believe most Android auto head unit only supports USB A to USB C for now unless your car comes equipped with type c port by default. Also if you buy the cable do let me know what is the model number? Thank you.

That's weird, the same cable worked with my note 10 plus. Gonna try my luck with anker

Fantastic glad to find this forum to discuss about s21.
How are you s21 users.
Well i am new s21 ultra 5G user just bought 2 weeks ago.
Sadly saying after 6 years switching from android 6 to android 11
Galaxy note4 to S21 ultra 5g

After 2 week of use i still have doubt whether this worth for the price or not. battery 5000 yet to avoid draining we had to disable all shit.

Currently my setting are

1. Set to dark mode
2. Disabled bluetooth
3. system sound and vibration turned OFF
4. 5G & 4G turned OFF, running on 3G
5. Nearby device scanning turned OFF
6. Turn on wifi automatically feature OFF
7. Detect suspicious network turned OFF
8. Display adaptive brightness turned ON
9. Motion smoothness in standard
10. Screen mode set to natural
11. Screen resolution FHD+
12. Always on display turned ON with tap to show for 10 seconds
13. Location ON
Yet i would not say it is impressive battery. Whats the point of having highend phone yet hav to adjust eventually.
Never streaming never browsing just playing with setting can drain the battery fast.
Some claims its happening due to recent update. I do not know.

S21+ got update already
