[Samsung Galaxy S21 Questions] blackhawk:
Either Package Disabler which is what I use or a adb edit.

It might as well be malware, it's pernicious and has just about every permission there is.

I edited my last post; found what/why I blocked UID 1001 on this phone.

Samsung's are sort of witchy...
[Samsung Galaxy S21 Questions] ze7zez:
On my Android 10, com.wssyncmldm has a UID of 1000.

I don't see Package Disabler in the Play Store.

Why block UID 1000 with the firewall, if the intrusive message always appears, even, with the network turned off?
[Samsung Galaxy S21 Questions] blackhawk:
It's not. Sent you link.

See this. i block UID 1000 and 1001.
[Samsung Galaxy S21 Questions] ze7zez:
Your advice is interesting, but it will not remove the intrusive message.
[Samsung Galaxy S21 Questions] blackhawk:
UiD 1000 and 1001 are unrelated, my bad. They are blocked because of security risks.

Package disable com.wssyncmldm as this is the source.

If not blocked it will eventually force the upgrade. It can turn on wifi and manipulate device power states without user permission. If you drive near a say an AT&T update tower it can slam load the upgrade very rapidly. It's not a benign annoyance... it's a menace.

If upgraded to 11 there's no rollback because the boot loader version is upgraded too on Snapdragon's.
[Samsung Galaxy S21 Questions] blankexistence:
Hey guys, I'm the OP. Can I take it from the discussion(s) above that this isn't a rectifiable issue? It's been more than a year since I opened this thread and at this point, I don't even care about the annoying message anymore. I've gotten used to it, but I appreciate everyone's feedback.
[Samsung Galaxy S21 Questions] blackhawk:
I gave the solution; either package disable or an adb edit to disable the OTA updating app.
[Samsung Galaxy S21 Questions] ze7zez:
If you know how to do it, please write.
[Samsung Galaxy S21 Questions] blackhawk:
Never had to... I stay as conservative as practical with these devices.

There a tutorials on XDA.

Here's one from Android Police or this.

Use LADB if you're running latter Android versions (10 or higher, I think), no PC needed.

Don't go too nuts. If you goof up a factory reset may be in your immediate future.
[Samsung Galaxy S21 Questions] ze7zez:
There is no known way to get rid of this message.

It is a system message.

I have a similar message on my LG G6 with android 7.1. The G6 phone, after getting an internet connection, immediately communicates that it is upgrading to 8.0. I purchased the full version of NetGuard from F-Droid. This will give the phone a full Internet blocker after restoring factory settings.
[Samsung Galaxy S21 Questions] blackhawk:
If you disable the OTA update app that should get rid of the message.

The carrier can also disable OTA upgrades on their side. I know AT&T can.
[Samsung Galaxy S21 Questions] Gravarty:
I know, bumping old threads is not cool but i have all of the OTA applications disabled and cache cleared and the message still shows up. It seems it's just impossible to get rid of that message after the OTA app already fetched a new update. I guess the only way to get rid of it, is to reset the device, go through OOBE without internet connection and then disable everything before connecting to the internet.
[Samsung Galaxy S21 Questions] blackhawk:
Did you try clearing the system cache from the recovery menu?
[Samsung Galaxy S21 Questions] Gravarty:
Yep, i'll try to reset my device later and try to disable OTA first and then connect to the internet.
[Samsung Galaxy S21 Questions] blackhawk:
You could block it with Rethink firewall too I believe. Remember it could come through on wifi too. Some carriers have dedicated high speed update towers as well such as AT&T.

If it's a carrier distribution, they can block OTA updates to your phone on their end. Had AT&T do this once.

Best if the OTA update app is completely disabled as it might as well be malware.
[Samsung Galaxy S21 Questions] Gravarty:
Okay i finally got rid of that message after resetting the device and block all the apps required for software updates, you don't even need to remove the SIM since it only checks for updates when on WiFi.
[Samsung Galaxy S21 Questions] blackhawk:
Good. That was close.

Thanks for the intel. Couple years back I read it could be purge by clearing the system cache, I think. I may be mistaken. At least it can be purged with a factory reset if worse comes to worse.

That wifi only thing... be careful with that. On Samsung's that app has all kinds of permissions. It's a bugger.
[Samsung Galaxy A52s 5G] jenda.69:
Update: Found the culprit! When the phone is on a 2G network, it happens always when there is any (voice or data) communication and glitches are stronger when the signal is weaker. It's probably caused by an interference and bad shielding of components. Similarly how 2G network makes buzzing sound in radio speakers, on A52s it makes a mess on the screen.

At least one user (bellow) solved it by RMA - sending the phone to service and getting back new/fixed one.

Update 2: Problem fixed. I sent the phone to service center with description how to replicate the issue (phone must be on 2G network, ideally low signal, data or voice transfer is happening). Got it back after 2 weeks. Report says they replaced the display and also battery for "construction" reason (as they described it) and issue seems to be solved!

To conclude: It is indeed hardware issue and is fixed by replacing the display. If this happens to you too, don't wait for software update or anything else, send it to a service for a fix covered by the warranty!

Since few weeks ago, maybe since last update a month ago (security update from 1st October 2021), I'm randomly getting graphical glitches on my A52s.

It usually happens when I wake my phone after few hours of screen off but today I also saw few flashes even when playing a (graphically not demanding) game.

There is colour noise flashing over parts of the screen. It is usually just few random quick couple of 1/100 sec flashes, sometimes it stays a second and it disappears and everything is okay after that.

I also saw noise not covering the screen but flashing instead of wallpaper... Like there's a corruption in graphical memory, driver or whatever.

It doesn't make a difference whether the phone is freshly rebooted or running a week or two.

Does anybody else have this issue?

Is my phone (the memory, screen cable or something else) dying or is ist just a bug in current system update? I don't experience any other instabilities or problems.

(I'd send my phone to RMA but since I didn't find any consistent way to replicate this, it would make just as much of a difference as locking my phone in a drawer for a month.)

I'm appending mock-up screen shots how some of the flashing glitches look.
[Samsung Galaxy A52s 5G] blackhawk:
Clear system cache, hard reboot.
[Samsung Galaxy A52s 5G] jenda.69:
Huh, I didn't really ask for help, but yeah, that's a good idea with clearing the cache.

I rebooted to recovery and wiped the cache partition.

(I also accidentally hard rebooted when trying different button combos to enter the recovery LOL, so I did both things. In the end I had to enter the recovery using "adb reboot recovery" command because none of the button combos I found worked for me.)

I'll report back in few days whether it solved the issue or not.
[Samsung Galaxy A52s 5G] filjusz:
Your screen is dying. This is hardware issue
[Samsung Galaxy A52s 5G] blackhawk:
Easy fixes are a good thing...
[Samsung Galaxy A52s 5G] blackhawk:
A possibility as is a mobo failure but no harm in trying a few simple fixes first.

Samsung has been having a lot of issues with their displays this year...
[Samsung Galaxy A52s 5G] jenda.69:
It doesn't really feel like screen itself is dying when glitches can appear under the home screen icons in wallpaper or in the application area with status and nav bars being untouched. But I guess it can be; I have no idea how the image on screen is being redrawn.

But it happens especially after phone display is off for longer period of time. The phone then is quite sluggish, presumably because the system paused or killed some apps and is waking them up. And glitches mainly appear then.

That would suggest to me either a system memory being corrupted or something weird happening in the cache, depending on where these apps go when they're paused/killed.
[Samsung Galaxy A52s 5G] blackhawk:
Factory reset. Before loading apps confirm if ok.

Then be careful what 3rd party apps you load.

If the reset doesn't work, reflash it to a known good version.

If all that fails it's likely hardware.
[Samsung Galaxy A52s 5G] gerhard_wa:
The most likely cause is a 3rd party app given right to overlap other apps and this 3rd party app has crashed. Uninstall apps in opposite order of installing until problem is solved. Or factory reset.
[Samsung Galaxy A52s 5G] Bvid:
I have the same problem, sent phone for repair.

In my case, the issue is occurring when phone is on 2g network. You could try going to network and set it to 2g only, check if it's happening, and then set it to 3g and see.

Cheers!
[Samsung Galaxy A52s 5G] abood.mhd:
So is it a hardware issue or software?
[Samsung Galaxy A52s 5G] Bvid:
It was a hardware issue, got a new phone.
[Samsung Galaxy A52s 5G] abood.mhd:
I have the same problem, and I can't replace the phone, the question is here, will this problem increase and affect the screen more?
[Samsung Galaxy A52s 5G] Saky22:
Same problem here...but mostly when I am on 2G network (anyone please try and post results)...Thinking of sending phone to service...will see how it goes
[Samsung Galaxy A52s 5G] jenda.69:
Huh, I didn't get notifications for my thread, so I didn't know about all the replies!

I tested different things in last few weeks and I came to the same conclusion - that it only and always happens when my phone is on 2G network. If 2G signal is strong, it's occasional small glitchy line here and there. When the signal is really bad, it just messes up the whole screen - I had my phone ringing with screen being all just noise and mess. So I guess it's probably because of interference similarly how the 2G network connection makes buzzing sound in a radio speakers. Except here it makes a mess on the screen.

Now that I know how to reliably replicate the problem, I'll back the phone up and RMA it after christmas.
[Samsung Galaxy A52s 5G] tmorgan82:
i have the same problem from the first day, it happens only in 2g signal ...and only if 2g signal is weak... i sent the phone to Samsung , they inform me that they know the problem and it will be fix ..on another update ...it s software problem they told....from this day i have take 3 updates and nothing happened....the phone still have the problem
[Samsung Galaxy A52s 5G] VirtualGamer20:
Same here, took my a52s to a Samsung authorized repair center, after 3 repairs (the third one being the display change) it seems that the problem is solved. To me, it has nothing to do with software.
[Samsung Galaxy A52s 5G] abood.mhd:
So, it's a hardware issue, I face the same problem for almost 2 months, and I don't know what to do
[Samsung Galaxy A52s 5G] VirtualGamer20:
Only solution is to contact Samsung and have it fixed
[Samsung Galaxy A52s 5G] Saky22:
Its not that simple...Some people send phone for repair...twice and still not fixed

[Xiaomi Black Shark 2 Guides, News, & Discussion] kevin mitnick:
the file of this methode seems like ubl for bs 3 KLE. you may check the bs3 thread. may it will be simple to flash, if the zip file contains patch0.xml and rawprogram0.xml, like bs3 ubl methode and flashed by miflash..
[Xiaomi Black Shark 2 Guides, News, & Discussion] kevin mitnick:
I tried this methode for unlock bootloader and there is some missing step that you dont mention..

after load image unlock.img, phone still lock. you need to go to bootloader mode, then type "fastboot flashing unlock", and

then reboot again to bootloader. you will get your phone unlocked

first boot took some minutes. just patient..

_____------______

the problem is, after ubl n root on android 10, fingerprint need to calibrate.

anybody know how to calibrate bs2 fingerprint ?

*#*#466349#*#*, SPMT,

i just stuck at "calibrate, put the flash chart then click next"

i don't know how to pass it

__________-------______

finally, fingerprint work fine.

I just flash the android 9 rom, then upgrade again to android a10 but still unlocked.
[Xiaomi Black Shark 2 Guides, News, & Discussion] osomakohj:
can i used this to backup full rom?
[Xiaomi Black Shark 2 Guides, News, & Discussion] osomakohj:
but this method should work on android 10? why do you have to downgrade?
[Xiaomi Black Shark 2 Guides, News, & Discussion] kevin mitnick:
yes, this ubl methode work on a10, but fingerprint didnt work. so that i downgrade to a9, and fingerprint work as well and then i up again to a10 and fingerprint nothing problem
[Xiaomi Black Shark 2 Guides, News, & Discussion] osomakohj:

[Xiaomi Black Shark 2 Guides, News, & Discussion] osomakohj:

[Xiaomi Black Shark 2 Guides, News, & Discussion] kevin mitnick:
ni, i dont. did you ?
[Xiaomi Black Shark 2 Guides, News, & Discussion] osomakohj:
I'd love to. but I'm afraid it will hard brick the phone
[Xiaomi Black Shark 2 Guides, News, & Discussion] julipxda:
Thanks a lot for this thread,

Following this thread I could unlock and root android 10, but of course fingerprint is gone. I have some questions about how recover it:

1- Is it possible to do directly in android 10? Maybe a magisk module or a calibration procedure? It would be the best option!

2 - When I try to calibrate in engineering mode everything is in chinese and I do not know what test is it? Do you know which test I should launch to try? Do you think the white paper, and black paper method, like rubber, will work?

3- If finally the only option is go back to android 9, How did you do the downgrade procedure? If I flash android 9 ROM (stock MP6), bootloader will lock again, and if I want to have A10+unlocked bootloader+rooted I would need to do again the procedure of this thread, doing a factory reset and loosing again persist.img partition, therefore loosing fingerprint again, I think. How is exactly the procedure of downgrade and upgrade to have A10+unlocked bootloader+rooted +fingerprint working?

4- In A10 maybe I can live without fingerrprint, but if fingerprint is not working I cannot set lock pattern or PIN. Do you know how to set lock pattern or PIN without fingerprint working? I tried to use faceunlock, but once set I cannot disable the option, and the feature it is not working right. It allows any face to unlock, what is weird. Anyone knows how to disable ?

Sorry for many questions. This mobile rocks and it is a pity to have lost fingerprint. I need A10 for pairing with new smatwatches, otherwise I would keep A9.

Thanks again for your knowledge and time.

Regards

what is your region when you unlocked sir S01 or S00?
[Xiaomi Black Shark 2 Guides, News, & Discussion] julipxda:
If you are in android 10, JOU11 update just follow this thread from the begining. Just consider step #7, (fastboot flashing unlock) after load unlock.img, as kevin mitnick suggest.

If you are in android 9 just follow https://xdaforums.com/t/rooting-bla...de-twrp-ota-fix.4089373/page-11#post-88506453

Both guides are perfectly explained and works

Remember if you do the proccess in android 10 probably fingerprint will be lost. Anyone knows how to recover fingerprint in android 10 rooted by this method?

thanks

[Xiaomi Black Shark 2 Guides, News, & Discussion] julipxda:
Hello,

I think tour problem is that you have done the process in emmc file system. You have to switch to ufs. So, when you start QFIL ensure in right-bottom corner ot the program that you switch to ufs filersystem.

I downgrade again to a9 and up again to a10, and in the moment of setting fastboot flashing unlock and loss again the fingerprint. Anyone knows how to downgrade to a9 and up again to a10, unlocking bootloader and not lossing fingerprint?

thanks
[Xiaomi Black Shark 2 Guides, News, & Discussion] julipxda:
Could you please explain how upgrade again yo A10 without loosing fingerprint. Anytime a set A10 fastboot flashing unlock I lose fingerprint, and I hace to do It because toniograde from a9 yo A10 bootloader has tonbe locked. I tried several times. Thanks in advance
[Xiaomi Black Shark 2 Guides, News, & Discussion] julipxda:
Di you try the method that Kevin suggest to downgrade to a9 and upgrade to a10 with nootloader unlocked? Everytime I set fastboot flashing unlock in a10 I lose fingerprint and also password and pattern lock. To update from a9 toa10 I ahve to relock bootloader and unlocking in a10 loses fingerprint. Do you know proper way to do it? Thanks a lot
[Touch Diamond, MDA Compact IV Themes and Apps] imperitus:
Does anyone know if the lumen sensor on the Diamond is accurate enough to make a good light meter application for use in photography?
[Touch Diamond, MDA Compact IV Themes and Apps] DeadShawn:
I would assume no, but I certantly dont know for sure.
[Touch Diamond, MDA Compact IV Themes and Apps] WvanWaas:
found this one it wil be possible http://www.clickapps.com/moreinfo.htm?pid=18788&section=
[Touch Diamond, MDA Compact IV Themes and Apps] madmezza:
I'll have a play and see - I've got WaterLevel installed which gives an indication of brightness on the sensor, and I've got a Sekonic lightmeter which i can use to compare the two.

I suspect that the TD's meter is nowhere near accurate enough over the whole spectrum...
[Touch Diamond, MDA Compact IV Themes and Apps] lazerin:
Let us know the results, would be interesting.
[Touch Diamond, MDA Compact IV Themes and Apps] imperitus:
The water level light meter is what inspired me to ask. It seems fairly consistent, but have no real way to see if it's accurate.

If it is a light meter application that also included stuff like DOF calculators etc... would be slick.
[Touch Diamond, MDA Compact IV Themes and Apps] blitzzin:
I bought the one that WvanWaas had linked. It workes great on my Onmia i910 thanks guys
[Touch Diamond, MDA Compact IV Themes and Apps] JimboOz:
Light Meter Accuracy for Diamond

There is an app - Water Level - that I use that is reasonably accurate at measuring lumens, but very directional using the small front camera - but it works well enough for OHSE evaluations. Whether its good enough for photographic use I don't know - and then you still have to develop the translation from lumens to ISO's f-stops etc
[Touch Diamond, MDA Compact IV Themes and Apps] kailuowang:
I am writing one.

The app is called Light Meter, Vesion 1.01a is currently available on the market.
[Samsung Galaxy S21 Ultra] Helixio:
I bought my Samsung S21 Ultalra 5G in Nigeria. Now living in Switzerland but the phone is unable to activate Samsung Health Monitor. Samsung says this is because the S21 Ultra sold in Nigeria have a different capacity and processor from those in Europe and cannot be swapped either.

Does anyone have an idea if I could do a major software upgrade or something to make this phone compatible with Samsung health monitor?

Hi people! My Redmi 9 going crazy every time I travel to US from CA. Roaming sign comes on and off repeatedly, voicemail notification pops up and data connection interrupts. Also, when I check storage, it says that I have 16gb of video files on my phone but I hardly have photos on my phone. I was trying to locate big files, checked folder by folder, no success. This "video" section of storage always growing... Only big downloads are offline maps and it's around 4gb. I was thinking to do a factory reset, but would like to avoid doing that.

But this list may have been abandoned as it has not been updated for a while. I wonder if there are any other lists similar to this one, perhaps more up to date?
[Xiaomi Mi 11] blackhawk:
Use Karma Firewall...
[Xiaomi Mi 11] seemebreakthis:
Karma firewall seems to be an app that acts like a VPN to achieve blocking traffic on a per app basis. For that you have AFWall+ which does a better job and it doesn't occupy VPN. Need root though for it.
