Sometimes, the photos took on the main cam is blurred. Even at daylight. At last, I know what to do. I put a cover/sticker on the laser part. And viola! The photos are always on focus and with much better sharpness.

    OneUI 6.1 will bring advanced battery protection features to S21U. It's still installed in 6.0, only it's hidden. The feature was included with Android 14.

    Here's how to activate it: https://techtrickz.com/mobile/enable-samsung-one-ui-6-1-battery-protection-on-galaxy-phone/

    Basically, install Activity Launcher from Play Store, search for battery pro, tap Device Care, and the only activity will be Battery protection. Tap it to open it. Then you can enable and choose options, including Adaptive, which keeps the battery at 80% until you wake up. You can even make a shortcut for it on the home screen.

      Geometry dash 2.2 , 28 Mar 2024Does it support android 15?Android 15 will be the last update for this phone since it was launched with Android 11 & according to the 4 years of update policy 15 would be the last with one additional year of security update.

        Jeeei, 22 Mar 2024Why? Is it bad? Probably because this phone is a few years old at this point. But in my opinion the S21U is still a good buy.

          Geometry dash 2.2 , 28 Mar 2024Does it support android 15?It has two more updates left I believe (1 OS, 1 security)

                        I have 5 s21 ultras. 1 has dead pixels and green lines, 1 has green and purple line only but she stopped using it and she switched to new oppo fold phone. 2 are normal phones in perfect condition (1 fresh phone and 1 office phone) and my main s21 ultra with 600+ games has only camera glass cracked.

                          Hi dears,
                          Unfortunately today I got to the Samsung service center. Yesterday evening I found my s21 ultra back panel slightly opened and the gum spreading to outside. It got me panic. When I reach the Samsung service center their dealings came decent. They said this happens very rarely may be the conditions the phone going through[very hot climate or something else]. But to my memory there's nothing conditions like that and I care this phone very much. I bought this phone on December 2022 but manufacturing date march 2021 that means almost 3 year old phone. So I understand this type issues may happen.
                          Service cost and overall cost- 5$(423/- indian rupees)

                            Sreenadh , 22 Mar 2024If you have bit more Money buy a s23 instead. Why?
                            Is it bad?

                              Here are the informations or future of S21 Ultra:
                              1,Last OS Upgrade is Android 15/OneUI 7
                              2,Last Security patch will be in 2026 any of the quarter
                              3,S21 Ultra will support One UI6.1 AI feature

                              If you have any plans to buy S21 Ultra My suggestion:
                              1,Look for S23Ultra instead [Android 17 will be the last ,security patch 2028*]
                              2,better performer [Battery,processor]
                              3,Better camera

                              *S21 ultra will discharge battery easily. In my situation 100to90 discharge quickly 90to50 take some time but still discharge speedy.
                              *while with 5g/Camera usage this smartphone heateup like hotcakes
                              *I'm not that guy believes in battery saving tips! I bought S21 Ultra for it's QHD display, 120hz refresh rate and so on.. for saving battery I never turned off this feature. If battery discharges I adjusted with charger or powerbank but I never compromised its most important features.

                                      OMG! Compared to my S20 FE camera, its 12MP is much much better than the 108MP even at night shots! What the hell lol.

                                        Between all if them:

                                        1) S21 Ultra: Great battery but it's receiving the last and final One UI 6.1 One UI update.

                                        2) S22 Ultra: Very crappy battery run time per charge cycle. I'd needed to carry around a USB brick battery with me just to make it through out the whole day. Stay away from this phone.

                                        3) S23 Ultra: Great battery and is still in full support.

                                        4) S24 Ultra: great battery with lots of AI features that comes with 7 years of support.
