      i have a green line on my Samsung s21 ultra screen, How I can solve this problem?

        A bug I may have discovered regarding UHQ.

        Connect DAC or adapter to 3.5 while bluetooth connected. Then, disconnect bluetooth without disconnecting wired headphones.

        UHQ becomes grayed out, and may stop working. Reactivates on visiting Samsung sound effects, but still grayed out. Gotta reconnect wired to fix.

        Understand A2DP, but I disabled that in my car, only HFP. And it happened sometimes, and I was thinking why, until I realized I was always in my car and exited car (turned it off) it when it happened.

          Hmmm, so I got tired of waiting for One UI 6.1 for Adaptive battery charging, so I used Tasker to enable Protect battery from 19:00 to 6:25, so it's full at 6:50.

          Tasker may need root for this though.

          To do so, install Tasker.

          https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm

          Give it everything it asks for. When done, it will ask simple or full experience. Choose full.

          Create a new profile by pressing plus, then select "CREATE", then "Time". Select start and end time when Battery protect will be on, then press the back arrow.

          Tap "New task" - you'll need two tasks total, so name it something like Enable Battery Protect. Press plus icon. In filter type in custom, then select Custom Setting. For name paste:

          protect_battery

          and for value type in 1.

          Press the back arrow two times until you're back to profiles.

          You'll see the green arrow and the name of your task you've created - this is your enter task, that gets executed when conditions are met.

          Now you need an exit task that gets executed when the time you've set passes. Long tap the start task, and tap Add Exit Task, and name it something like Disable Battery Protect. Repeat the process for the enter task, except for value type in 0. This task disables Battery protect when time you've set passes.

          Return back to profiles. Find the checkmark in the top bar and tap it.

          That's it. Add a status bar Protect battery option to quickly see it in action and if it works.

I personally like the rounded edges on the S21 rather than the sharp corners on the S24 also the S22, S23 & the S24 all look the same from front & back while the back design on the S21 looks pretty cool and makes it stand out from the crowd.

              I love the aspect ratio of the S21U. I held a 24U in my hand in the Verizon store a few days ago and absolutely hated it. The squared off corners made it even worse. Nothing about it seemed remotely appealing.

                  I think samsung going to update s21 ultra till Android 16 same as s20 ultra that extended to Android 15 with one year of security patches.

                    Try Frija or samfw.com, enter your model and CSC (and SN or IMEI for Frija) and find the latest for your CSC.

                    Then flash manually with ODIN.

                    Choose HOME_CSC, not CSC, as file for CSC slot in ODIN, as HOME_CSC keeps your data while CSC wipes it.

                      Current device. Good so far

                      Moderate charging speed (1hr 35mins max), good processor and camera.

                      Can't update to One UI 6 yet but fairs I guess. Wanted to get this bad in '21 but couldn't


                      Played games with bitches and a few video editing apps as well.

                      Still good enough for use in '24

                        This phone is well over 3 years old (I recently gave it to my dad and moved to the Xiaomi 14 Ultra). I wiped it and set it up for him (with the new setup designed to give optimal battery life). He gets three days on a single charge despite the battery being 3 years old.

                        Well done Samsung. The S21U was ahead of its time and was a marvel of a design. However they have sat on their heels and failed to innovate much since then. Hence my jump away from them.

                        Oh how I wish a true class leading successor to the S21U was in the cards. I hate the squared off design of the 22U, 23U, 24U, etc. I also could not possibly care any less about having a stylus. To me that just takes up valuable interior space. I'd make a trade for another 500mah of battery any day of the week in place of that (or better camera hardware).

                          Superb phone!! Went to the riverside took lots of pics of friends, family and nature with different modes all turned out great, the battery lasted till the next day I'm using the Exynos version & no complaints so far still get fast updates (April being the latest). All in all a very satisfying experience using this phone ❤️

                            So I tried call recording in Firefds Kit. It starts recording after call is connected and adds a new option in the phone with an option to autorecord calls.

                            And it works.

                              Camera is pretty decent if not outstanding but that's the case with almost all phone cameras. I've tried the S22 Ultra camera & it's way to contrasty compared to this. As far as battery is concerned for me it's quite satisfying as I use standard refresh rate minus QHD (I don't game on it) with all useless apps put to deep sleep plus some handy tricks to save battery life so for me it lasts for over a day with somewhere around 7 hours of SOT. Overall it has been a good experience using this phone even in 2024.

                                Sreenadh R, 13 Apr 2024Using S21 Ultra 5g for more than year now. These are the pr... moreCon #1: I don't know about previous One UI since I bought it brand new recently and updated to latest, but the cameras seem to have good details. I'm not a photographer but everyone is impressed with the details and quality. Except 10x in low light.

                                Con #3: I get 8-10% battery wastage per hour with screen on as shown by Battery Guru, using Brave browser, 16%/hr plus battery heatup with music with JamesDSP + ViPER4Android. Idle, with Naptime (Doze turns on much sooner than stock) in NFS Injector plus sensor disabled during Doze plus deep doze plus doze optimizations in NUKED I get maybe 1% per hour idle (screen off). In contrast, Firefox heated up my phone and wasted more battery than Brave (but with tons of addons). It depends on the apps you use and so on. I also turned on Adaptive battery. I also put most apps in deep sleep, and a few in sleep.

                                Con #4: That's battery management at work. You can force it to keep up to 5 apps constantly on, not killing them, by opening recents, tapping the app icon, and selecting Keep open. Plus, in settings you can choose apps to never sleep.

                                Con #6: Again, see #3

                                Con #7: Same happens with FTP transfer through WIFI. Don't know about 5G (don't have it here) but I think constantly using it to transfer huge amounts of data quickly, just like FTP, taxes both the radio and the internal storage. Other than music and constant and long WiFi FTP transfer (10 MB/s for 2.4 and 30 MB/s for 5 GHz) the phone doesn't heat up. And how do you know Snapdragon doesn't heat up too in same conditions? I'd rather have Exynos than SD, since I use root for Doze optimizations, NUKED scripts, Neo Backup apps and app data backup and restore plus those two audio effects I mentioned. Oh, and LSPosed (successor to XPosed) modules which can customize and unlock many features. Plus Magisk modules.

                                With root, you can always set the governor to Conservative in SmartPack Kernel Manager - Conservative keeps CPU cores at lowest possible frequency and only rarely ramps it up but really slows down the phone when video editing and all that (but UI is still smooth as ever). Or even powersave governor for even more power saving but even less performance.

                                  Alright.

                                  I chose Hi-Res Output, enabled USB DAC, and chose 352.8 kHz. That put the Shanling UA3 into 384 kHz sample rate, and the indicator lights up purple to indicate this. It's using 32 bits. But the volume is lower. 192 kHz and lower gets me normal high gain it's capable of, with the indicator lighting up yellowish-green to indicate 192. Still 32 bits at auto.

                                  All audio effects (JamesDSP and ViPER4Android) work with all sample rates.

                                  OpenSL ES shows 48 even if I choose 44.1. And 24 bits if I enable 32 bits. Even though PowerAMP is showing 48 in OpenSL ES, the indicator is still yellowish-green when UHQ is on, which means the DAC/AMP detected 192 kHz on a hardware level, and I tend to trust that more as it's always right, even in Windows and Linux when you manually choose the sample rate.

                                  So up to 384 kHz / 32 bits in PowerAMP is supported, IF your DAC/AMP supports it, with the issue of low gain on that sample rate. 192 is normal, double the volume at least of standard 3.5 mm adapter and 384 kHz. Plus all that power means I can REALLY ramp up the bass with UHQ, ViPER4Android, JamesDSP and jetAudio without it lowering volume, even at over 50% system volume turned up (which is WAY too high with ATH-M50x, 34 out of 150 as shown with Sound Assistant expanded volume notification is plenty enough).

                                  If you're interested in UA3 since you like high sample rates, you can find it on eBay (no, I won't link it, for fear they'll delete my comment) - find annie-audio seller, it's 20 USD postage from China, but it arrives well-packed and in 2 weeks or less. Also, a good-quality replacement durable cable is ddHiFi TC07S, from the same seller, expensive but really durable. Since Shanling UA3 has a detachable Type-C port, you can use ANY cable with it and it will work; and not worry about it dying because of a faulty cable since you can just replace the cable. Except iOS devices, which need special Type-C OTG cables.

                                    And JamesDSP for systemwide effects, bass, convolver and AutoEQ.
                                    And ViPER4Android for systemwide effects plus additional bass plus ViPER Clarity.

                                    You can use RootlessJamesDSP in conjunction with Shizuku to get systemwide effects plus AutoEQ but it won't work in every app. Or Wavelet + adb (or Shizuku + aShell to send adb without a PC) to get systemwide AutoEQ plus a few effects in legacy mode.

                                    You can download a good bass convolver called Magic Bass here: https://xdaforums.com/t/irs-sound-mod-vinardos-impulse-response-samples-elements-of-fidelity-ex-dolby.2765331/

                                    I'll check out PowerAMP and see the sample rate and bits for Shanling UA3 and report after I charge my phone later.

                                    Edit: I think PowerAMP just shows the sample rate and kbps of the song, not of what the system is using, because it showed 48 kHz for Over the Horizon ringtone and 44 kHz for an mp3, and 44.1 kHz and high bitrate for another FLAC. Rest assured, if it supports it, and UHQ is enabled, it will use it. I will check out later once my phone is charged, since the indicator on UA3 shows clearly 192 kHz used.

                                    Edit 2: nevermind, found the sample rate used by device option in setting by searching.

                                        This may be obvious, but coming from S10+ which was using LineageOS 20, I was annoyed by slow install speed.

                                        The culprit is McAfee virus scanning bundled with One UI. So turn off virus scanning while installing for a massive install speed boost.

                                        To do so, go to Settings -> Security and privacy -> App security -> App protection. Tap the three dots in the upper right corner, then tap App protection settings. Then turn off Auto scan when installing apps.

                                        This provides a massive boost in install speed, at the cost of no malware scan when installing apps. But if you already know that sideloaded and Google Play apps you installed or plan to install are virus-free (and I have yet to find a virus since I had my first Android, Galaxy S3) you can turn it off while installing those apps en-masse (such as when restoring from your previous phone or from a factory data wipe), and only turn it on while installing one suspicious app, then turn it off after that.
