Note 20 dual sim camera not working after update - Samsung Galaxy Note 20 Questions & Answers

Hello,
I have a Note 20 and after Samsung update camera is not working, I did the steps found on the internet with camera reset and factory reset and is not working
Any solution to this problem exist?
Thank you!

Welcome to XDA.
Yes, well... updates can and do break Samsung's.
Rule #1 - if an OS is fast, stable and fulfilling its mission, let it be!
About the only thing you can do is try clearing the system cache and maybe a hard reset. Otherwise reflash to last known good firmware... a Samsung Experience center at best buy may be able to help.

[Q] [Mango 7712] Sudden reboots after upgrade

Hi all,
is anybody else also experiencing sudden reboots on his Mozart device after flashing WP7 to Mango 7712?
Most of my colleagues don´t have any problems with Mango.
There are no specific task when the reboots occur. They just happen all of a sudden, even if I don´t use the device. It´s very strange.
I checked all available device info with my colleagues and all version numbers are the same to the last digits. Maybe it´s a memory card issue?
Overall, the Mango experience is great and that´s why I don´t want to go back to NoDo. Just the reboots are driving me crazy... I haven´t found a solution so far. Maybe I will try a hard reset.
I reverted to NoDo out of curiosity and to make sure I haven´t done anything wrong in the flashing process. But after reflashing Mango again, the device acts just the same as on the first try. So I don´t think its a process issue.
Well, in the end I will have to wait for the real Mango release...!? But maybe someone can share some valuable information on this issue?
cheers. simon.
I had the same issue with Mango on beta 1 when I used the unoffical method of getting the beta.
I reverted back to NoDo and preformed a hard reset, the used the offical method of getting the beta 1 and now beta 2, neiter of which caused any issues. I can only suggest that an app is causing this problem for you.
Yeah, I had the feeling that the only way to clear out any questions would be to do a hard reset... I will try a hard reset on the 7712 basis. Maybe that helps...
I will post any results when I am through this
Thanks so far...
...a hard reset with Mango 7712 did the trick. I assume some App was causing this behaviour.
I´m now very happy with 7720! Thanks for the hint with the hard reset. I was a bit afraid of having to reinstall all my apps but in the end I am happier now with a stable Mozart

[GT-9100] Multiple problems after factory reset

Hello everyone,
I have a samsung Galaxy S2 and facing quite enough issues with it.
Problem started when one fine day "Media scanner" kept running. I googled for that problem, uninstall few doubtful apps,
cleared off other data but all in vain.
Finally, I did factory reset to get rid of this. After factory reset, I got below problems :
1. Lag in Samsung keypad
2. No audio at all (alarm, incoming calls, music, FM Radio etc etc.)
3. Camera failed.
4. And some times, face issue while rendering.
To solve first one I install swiftkey app which is working fine.
For audio issue, I googled but nothing was useful for me.
Currently, my device has Android version 2.3.4 , i.e. as it was shipped.
I am thinking to update to Ice Cream Sandwich (thinking that can solve all issues) but before that need opinion of experts.
If anybody can "pinpoint actual issue which caused all this or give some direction in solving this" , that would be great help to me.
Thanks in advance for help
With Regards
Neha
First don't go to ics 4.0.4 stay well away from that firmware :thumbup: flash lsw 4.1.2 and report Bk mate. You can use ics 4.0.3 if you want though.

Firstly, Thank you for suggestion.
Secondly, I want to mention, my device has started working smoothly its own. Today morning it got fully discharged and got shut down, after charging it is working without any issue. I am not sure, whether battery charging/ discharging has some link to all those issues because I had rebooted it many times.
Anyways OS upgrade is required, hope my experience can help somebody else also

Maybe the fingerprint sensor was damaged, I suggest go to service center and let them check it.

Thank you :good:
But I installed Resurrection Remix to my phone. The rom has 2 bugs. And then I installed android 5.0.2 from sammobile. I think this problem for this reason

Besides even the fingerprint scanner doesn't work you can still use your phone so don't do anything that will make it unusable.
Anyway Galaxy alpha was released september 2014 so its still under 12 months warranty, but for safe just leave it to the experts

You're right. But I rooted this phone
i do have the exact same problem. fingerprint won´t work after i flashed Resurrection Remix.
I even did a full reset to stock with kies. still the fingerprint won´t work.
Anybody know a fix? maybe it has something to do with knox being set to 0x1 ?

Maybe hardware error.

But it worked fine before. Why would it suddenly not work after reflashing stock rom again?
It didn´t drop or anything that would explain a hardware error.
I have exactly the same problem. Was happening before Xmas so they sent it away for repair. Apparently some glue had come loose!
But 2 months ago it happened again. I cleared the cache and forced stop on the fingerprint and it worked for a day or two. Then stopped again. About 15 attempts to do the same again and it finally worked long enough for me to change my backup password to something simple. Not worked for weeks now even though I've done a factory reset. The about 4 weeks ago my boyfriends alpha did exactly the same! Surely this shows it has to be a software issue? I'd love it to work at least long enough so I can change to pin to unlock.
Same thing happened to my alpha .
It was working fine since i bought alpha (7 months)
But now its not working , now what to do ?
Service centre has ordered Home button/Sensor .
Will it fix ?

Are you sure you never damaged the home button, perhaps dirty fingers or scratches can cause issues to the fingerprint scanner.
No , i haven't dropped my phone or scratched .
I feel the same friend .

Hello, I too feel the same, update my Samsung Galaxy Alpha and not work the fingerprint reader . There is a solution ? I'm worried.
I went to the service centre , and they replaced home button in warrenty.
Now its working
Well, I have the same problem. My Alpha G850F is under Lollipop.
We actually are a lot of users having problems with the fingerprint sensor, isnt'it?

Probably use Titanium Backup and clear all data on Application "Fingerprints" Try again but didn't work search on youtube.

Also I have this problem too but not rooted or never factory reseted my phone...
Mine too does that...what can I do?
Has anybody downgraded to a lower update? Maybe early 5.0.2 firmwares or even 4.4.4 and see if it gets fixed?

No calls, home and recent apps button won't work

Hi guys, this morning my father's Le Max 2 (snap820, 4/64) stopped receiving calls, and both the home and recent apps virtual buttons decided not to function, too. Strange enough, I'm able to long press them and get the action I'm supposed. Any ideas/fix? I've already checked the phone for malicious apps and misconfigurations
Hi, I have exactly the same issue, plus I cant download any more applications from play store. Can anyone help?
If you have a backup taken when the phone was working well, I'd suggest you to restore it. If not, try another ROM, or at least a different ROM flavor (if it had an EUI based ROM, use LineageOS and viceversa). If that doesn't work, you may need to get into Qualcomm recovery mode and flash the developers ROM to get the phone to a real factory state.
But first, try to revert to factory settings from the current ROM, and see if that solves the issue.
There are several threads here with info on how to apply the above solutions.
If none of these solutions works, and you still have warranty time left, you may want to contact the seller for a repair or replacement.
Good luck.
Do the notifications work?
I was on holiday, so no PC I could use for flashing or else. A reset from the settings worked, still don't know what caused the issue sadly
I couldn't find the fix for this in any other threads, can someone help a not-terribly-tech-savvy person with a fix for this
Today I also had a same problem. So just I backed up all important data's and done factory reset. Now everything works fine.
Everyone have same problem at the same time means the ROM has virus or Trojan.
What is the ROM everyone is using?

Huawei P8 Lite 2017 storage issues

Hi there. On November 2017 I bought a Huawei P8 Lite 2017, and till now it worked pretty good with all the rom updates etc, but since 3 days ago the internal storage it started to become full and full without me installing anything more! And don't ask about caches, I erase caches everytime. I also did a factory reset. Then I read on the web it's a common problem, but I haven't found a solution. Anyone knows if there is a solution like rollback to Nougat (I have the latest version of Oreo)? Any advice would be appreciated
