[Nexus 7 (2013) Q&A] corabict:
I've used the tablet for 6 years now and suddenly ... The battery drained to 0 so after charging and powering up .. it got stuck at boot loop, as it gets to the word android after the 5 dots animation. then the android is starting - optimizing app x of 37...

I've tried disconnecting the battery cable and reconnecting them again.

Wiping cash several times.

Usb debuging is enabled.

No root or custom recovery.

The question is .. if I can solve this problem without factory reset as I would resort to that if there's nothing else ... I have some important data That I'd like to backup if I can. even IF I can backup the data then factory reset it .. that would be fine.
[Nexus 7 (2013) Q&A] :
if ok connect to computer then you can move files to computer
[Nexus 7 (2013) Q&A] corabict:
I can't choose file transfer as USB mode .. so I can't see the files .. even though I hear the sound of USB connecting but I can't see the device.

If your hardware/eMMC is not faulty, then...

If it is

unlocked

, flash/boot TWRP and get your data.

If it is

locked

, get RESTOCK and try SAFE UNLOCK...

"Unlock your device without data loss. MiFlash is described in the Unbricking Guide:

Thank you so much for your help.

I tried to do that and it returns an error

adb: error: remote object '\sdcard' does not exist

I tried to make sure the device is recognized so I used Adb devices and it returns:

* daemon not running; starting now at tcp:5037

* daemon started successfully

List of devices attached

057f2788 device

But that when it's stuck on the animation optimization loop.

If I'm in bootloader ore recovery mod ... it returns

List of devices

And it's empty. So what do you suggest.

Thank you so much for your help.

I used restock 1 and it downloaded the stock but after that ... I get that

Can't install .inf

because it is not better than the current drivers.

INFO: Returning with code 0x100

Device not found...

1. disconnect it from PC

2. reboot to bootloader again

3. reconnect it to PC

Press any key to continue . . .

And I can't get past that.

Sorry for bothering you ... but really I Don't know what to do.

I used ADb shell then ls ... and listed all the files and sdcard is one of them but when I try to access it it returns this error

cd: /sdcard: No such file or directory

Then tried ..

>> Adb shell ls /sdcard/sdcard

it returns the same message.

>> c:\Adb>adb shell ls /mnt

asec

So why this error??

Do I need root or what. ??

and if so can I flash twerp and do backup ..if you have any links,

THank you very much for your help.

[Samsung Galaxy S21 Ultra] snobrdinrtiste:
I keep having issues with my fingerprint sensor... constant "fingerprint doesn't match" or "Press Harder" or "... cover the whole area..."

This is with a whitestone dome on the phone...

Anyone else having this issue?
[Samsung Galaxy S21 Ultra] cubantigre180@hotmail.com:
I have a galaxy s21 ultra being used with a case by a company called you maker. It originally came with a plastic sticker that was protected and covered. That circular plastic sticker allows the finger to be read using the ultrasonic technology while being in a case. There's another technology that uses light to make almost a 2d image of your print. Try without the case and see if it works. Also sorry about you inconvenience.
[Samsung Galaxy S21 Ultra] snobrdinrtiste:
well... there's no way i'm gonna take the whitestone dome off since its cured... just wondering if other peeps with WD tempered screens have the same issue with the fingerprint sensor
[Samsung Galaxy S21 Ultra] Outbreak444:
Had that issue with my S10+ as well. Try removing fingerprints then adding them again - assuming you didn't register after installing the screen protector. Another thing I had done was register the same fingerprint multiple times.
[Samsung Galaxy S21 Ultra] galaxyultra:
I have the WD screen protector on my S21 Ultra and I'm having issues with my fingerprint sensor also. I'm very disappointed because for the price, I expected it to be fully compatible with the fingerprint sensor.
[Samsung Galaxy S21 Ultra] jutley:
The Samsung ultra comes with x2 screen protectors people rip the first one off or finger print sensor will not work i found this out the device has a second screen protector so no need to worry :)
[Samsung Galaxy S21 Ultra] Geekser:
Forgive me if this is a stupid question, but did you take off the factory installed screen protector that comes with the S21 Ultra? Not the one that you take off when you first remove it from the box (sort of a dust protector) but there is an actual screen protector there - very hard to see unless you look very close - if you did not remove that, then that is most likely your problem. If you did remove that before installing then I am not sure why you are having issues. Either way - best of luck my friend.
[Samsung Galaxy S21 Ultra] nxneko:
Only exynos variants come with screen protector, My U and U1 arrived without it. So just need to ensure finger print is re-registered. Did not use whitestone dome due to experiences with note 9 glass but the spigen glass is working well with finger prints once registered after application
[Samsung Galaxy S21 Ultra] galaxyultra:
Yes, I removed the original film that was on there. I also went to the "Display" menu and increased the touch sensitivity option. In addition to that, I registered the fingerprint of my thumb 3 times. I can't seem to unlock my phone in the 1st attempt. It usually takes multiple attempts for it unlock. From a visual point of view, the screen protector installed perfectly. I just wish it was fully compatible with the fingerprint sensor.
[Samsung Galaxy S21 Ultra] snobrdinrtiste:
this is the exact same thing i'm experiencing!!! So annoying! I wrote to Whitestonedome and asked for a refund. Plus the bottom of the whitestonedome's glass is starting to peel ... even though it was cured and everything was fine for four straight days.

And no, the phone did not come with a pre-installed screen protector.
[Samsung Galaxy S21 Ultra] Geekser:
For what it's worth, the Fingerprint sensor works awesome for me. I have not added a glass screen protector and probably won't. For now, I am simply relying on the one installed by Samsung at the Factory - but I also have another Film Protector from AM-FILM that I will use if necessary. Very happy with how fast the FP sensor is - much better than on my previous phones....
[Samsung Galaxy S21 Ultra] Sonin66:
Have both 21 ultra and whitestone dome glass installed. I have noticed that my finger slids a little not being use to glass as I tried for the life of me to use glass with my s10+. Couldn't get whitestone to work so I got zagg fusion glass. I have also noticed that if you have dry ass fingers, like after washing, it won't recognize your print. Try with lotion!
[Samsung Galaxy S21 Ultra] galaxyultra:
If only Samsung ditched the curved display for a flat panel, then we can buy "normal" screen protectors at fair prices.
[Samsung Galaxy S21 Ultra] Sonin66:
The curve screen is a little annoying but also satisfying also
[Samsung Galaxy S21 Ultra] mankvl:
I have problems with original screen protector sometimes, registered finger only 1 time but I get same errors might just peel it off but don't know will it help any :)
[Samsung Galaxy S21 Ultra] joancolmenares:
I haven't removed the screen protector that comes with the phone from factory (not the one that you peel when you take it off the box... No issues with fingerprint sensor.. I had a note 20 ultra and I did the stupid mistake of removing the one from factory and putting one from amazon that had the circle for fingerprint.. I had to readd all prints and the worst thing is that it would miss more than hit. When I got my s21 ultra I was smart enough to keep the protective film that came with it. Other than that, I would suggest custom made with hydrogel (something I have seen where I live) which is flexile yet durable and works great with fingerprints.
[Samsung Galaxy S21 Ultra] eldrid:
I installed a generic £4 UV glass screen protector from ebay. Initially I had the exact same issue. But now it works for me. The trick I realised is to remove the old finger prints and re-register them. You will need to register the same finger 2 or 3 times and you will need to use a little more pressure when using the fingerprint scanner to unlock. It is still not as reliable as it would be without a screen protector and you will get a few misses but it gets the job done. I prefer using face unlock most of the time and use the fingerprint scanner only to make payments, access the banking app etc and for that it works fine I just need to press into the screen gently vs just placing my finger on the scanner as I would otherwise.
[Samsung Galaxy S21 Ultra] johnp357:
I don't understand how people claim that screen covers work perfectly well with with this phone's fingerprint sensors. i have tried AMfilm glass, and two soft ones by unique me and... even after the extra sensitivity was turned on, the fingers would fail most of the time. since you only get 5 tries before it locks.... so annoying... are the people that write those ratings all bs?? btw.. first experience with an ultrasonic sensor and it kinda blows..... am i out of luck? never had a phone without a screen cover ..... sigh
[Samsung Galaxy S21 Ultra] Sonin66:
If you don't mind not having glass, a zagg will work for sure as I had it on my S10+. Currently running whitestone and if my fingers are just washed, it won't work. But if I rub them together or add lotion to my hands, it reads it with no problems. I have also added my print a few times in different variations like the side of my thumb and the tip of my thumb to make sure it can read any part of my thumb
[Samsung Galaxy S21 Ultra] sesnut:
If you tried 2 soft ones and those didnt work, thats a you problem
[Samsung Galaxy S21 Ultra] eldrid:
I installed a generic £4 uv glue glass screen protector from ebay and it works with the fingerprint sensor. You dont need to buy the expensive dome one as they're technically all the same. I had to re register my fingerprint and i have to press like i am pressing a button rather than just touching the sensor like i was used to but it certainly works and that too most of the time. I do get the occasional fail. Follow this video on how to install it properly and it should work.
[Samsung Galaxy S21 Ultra] johnp357:
thanks for answering while not bothering to read the statement... real helpful
[Samsung Galaxy S21 Ultra] sesnut:
you literally said nothing other than you tried a glass one and 2 film protectors and none of them worked for you.

thats a you problem

youre either installing them wrong, your fingers are too dry or your sensor is bad

pick one
[Samsung Galaxy S21 Ultra] RoWilJr:
I have the Whitestone Dome installed on my S21U and the FPS works just fine for me. Even forgot to remove my fingerprints before install.
[Samsung Galaxy S21 Ultra] johnp357:
go away..
[Samsung Galaxy S21 Ultra] mrnovanova:
If you add glass on top of glass on top of a sensor that senses vibrations as opposed to light you have to expect that it won't be a seamless experience. No matter what Domeglass promises. The scanner is meant to work with the pre-applied protector or naked.
[Samsung Galaxy S21 Ultra] Outbreak444:
Oddly enough, my WSD is still working fine 24 hours later. Had issues with my S10+, but the new jig WS provides seems to help improve things. I did have to add my fingerprints again, but it works flawlessly now. I didn't even turn on touch sensitivity (which I'm almost positive doesn't do anything for the fingerprint scanner anyways). Every once in a while I'll get a "cover the entire sensor," which I got frequently before the WSD install, and only once have I received a "press harder" message. I'm very satisfied with my WSD.
[Samsung Galaxy S21 Ultra] proxybox:
Solved!

I tried all the suggestions: enter both thumbs under one fingerprint recognition session, remove battery optimization for biometric devices, breathing on my thumb and never got consistent results. It was actually making me think there was a hardware issue on my brand new S21+. Before going down the factory reset route, I found an article that mentioned clearing the cache in Recovery.

So... I entered recovery: Power down, hold the volume up+power key to enter recovery. I selected clear system cache and also repair apps. On reboot, the phone started up and took awhile while it did it's app repair process. Now my fingerprint works great!!!! I set my phone, messaging, calendar etc apps to Google. When I ran the repair apps it reset these all to Samsung. However, when I launched each application again, I just chose the respective Google app as default and everything is golden.

Hope this helps all you guys who are having inconsistent fingerprints.
[Samsung Galaxy S21 Ultra] rockky:
"Only exynos variants have screen protectors".

God I was pissed off when I found that out.

Found it out cause I got a small scratch on the screen, one that wouldn't have happened on my 10+. Went to check on the protector .

None there.
[Samsung Galaxy S21 Ultra] SaintlySins:
Geeezus ... I hope this works!

I've had my S21 Ultra for 5 weeks now and the fingerprint sensor is CRAP !

I have followed every post that offered a solution and they all failed after the first 24 hours.

I'm going to do this on Thursday (I'm off that day) and hope it works as well as you stated.

I'll post my results.

Thank you.
[Samsung Galaxy S21 Ultra] proxybox:
It started acting up again but not as bad. I found a pattern in my case. If it starts behaving badly, I double tap and shut the screen back off. I redouble tap and open the fingerprint back up and on this next 'wake up' it works instantly. I also noticed for apps that I have set to use fingerprint that they work flawlessly so I figured once the fingerprint unlocks the phone it is in a ready state and when I unlock the specific app it works without issue. I truly believe this has something to do with sleep / battery saving. Hopefully Samsung will issue a fix on the next update.
[Samsung Galaxy S21 Ultra] lywyn:
That is why I opted for the WSD glass, the glue bonds the two together. The rest use glue spots and do not make a full cohesive layer. The WSD works great for me and I just have both thumbs set up
[Samsung Galaxy S21 Ultra] Hosehead:
I use the Whitestone Dome and had to delete my fingerprints and start over. Since then, fp unlock is working great. Not as sensitive as my Note 10, so I have to pause a few milliseconds more, but no big deal.
[Samsung Galaxy S21 Ultra] SaintlySins:
Thanks for your truthful update .... as it's nearly the same issue for me.

I think I'm just going to have to go to a code.

This is a ridiculous scenario as I'm sooooo used to how effective the LG fingerprint sensor was on the back of the phone ... and now 5 years later, Samsung can't get this right at all. And it's not like anyone is saying their not having a single issue and it's working perfectly on any forum.

We can land a spaceship on Mars, unload a helicopter and have it fly around on another planet ... and my bank and girlfriends salon can instantly ID someone with a fingerprint sensor .... but Samsung can't get this dialed in right. WTF !?!
[Samsung Galaxy S21 Ultra] proxybox:
Agreed! My Dell Latitude 7490's fingerprint reader will register but never unlock. I gave up. It's weird because these are designed for enterprise and you would think the fingerprint would be extensively tested.

My cheapo Motorola unlocked without issue too.

Just updated to the latest Samsung update today and it seems to be a little more consistent. I can live with it now since I know a quick way to get it to recognize but I do want a permanent fix.

BTW, going to a code? which phone is that?
[Samsung Galaxy S21 Ultra] shaunydub:
I removed my factory installed screen protector and now 99% unlock.

I experienced the same frustration going from Hauwei P30 Pro which was nearly 100% unlock to Note 10+, quite sad Samsung did not improve during this time!!
[Samsung Galaxy S21 Ultra] SaintlySins:
I've tried multiple tricks from multiple forums ... none are any better.

This is awful!

(I'm finding a lot of things wrong with this phone - incomplete Samsung Apps, (Video Call Effects & Calendar Notification Bar Icon doesn't work & more).

Samsung sucks ... why couldn't LG just marketed more, such a great phone!?!
[Samsung Galaxy S21 Ultra] Subin khan:
I have exynos version but my phone does not have preinstalled screen protector. I think preinstalled screen protector country specific not HW
[Samsung Galaxy S21 Ultra] meroupow:
I found this

increasing the screen sensitivity helps massively the fingerprint scanner for me with the factory screen protector still on.

Too bad they do not activate this parameter by default for all S21 coming with factory screen protector in my opinion.
[Samsung Galaxy S21+] lalakersfan29:
I jumped on the S21+ T-Mobile variant as it was offered with extra $100 off, cheaper than unlocked. I assumed the phone would be able to be used on any carrier since it would be fully paid off. But inserting my Verizon sim, I'm greeted with it saying the sim is unlocked and a reason code 132. Anyone have any ideas on what's going on, what I should try, or just return for unlocked version?
[Samsung Galaxy S21+] chazfarote:
Try calling T-Mobile for the unlock code. I thought phones in the US weren't locked anymore or maybe they won't be in the future. Good luck!
[Samsung Galaxy S21+] lalakersfan29:
Thanks. I'm working with T-Mobile now, and they have suggested that I make a T-Mobile account then try to unlock it. Hoping all goes well
[Samsung Galaxy S21+] Seamonkey79:
T-Mobile can't even *see* the phone to unlock it if it isn't attached to a T-Mobile SIM, so they won't be able to unlock it (nevermind willing) without that. If you can get one in there, you might be able to use 'team of experts' through Facebook or Twitter and have them unlock it, they're pretty good about working around normal limitations when you explain situations to them. We were able to get a still on EIP iPhone unlocked when we were in the Philippines by letting the TES agent know we were wanting to put a local SIM in, I would hope they'd be willing to work with you if you let them know you didn't realize it would be locked.

Will eat into your $100 discount some, though, with the risk that they tell you it still has to be active on T-Mobile for 45 days. I've always had good luck with them, they seem to be more capable of independent thought than a normal call-center person, provided you're calm with them.
[Samsung Galaxy S21+] jcrompton:
@lakersfan29

Were you ever able to solve this? I have exact same thing going on with a Galaxy Tab S7+ that was bought directly from Samsung. Thought was too be unlocked but it's locked to TMobile. Strange thing is 3 different stories from 3 different TMobile reps. Phone can't be locked since you bought from manufacturer. Yes we can unlock it. And no we're can't unlock it until you've spent over $100 with prepaid fees lol. 😭
[Samsung Galaxy S21+] krisology:
Yes. Actually it was pretty straightforward, I sent a message to tmobile T-Force on twitter and I provided my imei and they said it would take up to 72 hours to unlock. And they followed up with me notifying that it should have been unlocked. It works, using service on verizon now
[Samsung Galaxy S21+] jcrompton:
Was it @TMobileHelp that you actually tweeted
[Samsung Galaxy S21+] jeyd02:
Download tmobile device unlock app from playstore and try unlocking.
[Samsung Galaxy S21+] jcrompton:
So thank you for the suggestion. The Twitter TMobile contact was the secret. After hours on the phone with T-Mobile support (and without being super critical they were just NOT very knowledgeable .... I think I knew more than they did) the Twitter alternative was quick and easy. They added the IMEI to their system and I was unlocked in less than 24 hours.
