Fingerprint Scanner not working - Galaxy S 5 Q&A, Help & Troubleshooting

Hello I wanted to know if its common this issue for galaxy s5 users... I updated my phone to android 5 lollipop and my fingerprint scanner is no longer working.... it says "an error occur with fingerprint sensor, if this message appears, restart your device"
I need some help. my S5 is the SM-G900F

Actually the same problem happened to me. After I updated to Lollipop my fingerprint scanner stopped working and giving me the same message.

Hey even I have the same problem. I hard resetted the phone and cleared cache and the same error message pops up. Right now I'm really frustrated. Why don't you guys try to clear the fingerprints cache in the application manager and see weather it works.
I hope it isn't a hardware problem with my device.

You may need to update the bootloader through odin

I have the same issue. I have "officially" updated to Lollipop 5.0 via KIES in Malaysia about 1.5 weeks ago. Next day the succes rate of the fingerprint drastically decreased and on the 2nd day fully stopped working withe the same error. I have restarted many times but the issue persisted. I could not go in the fingerprint settings. I have cleared the data of the fingerprint t app in the application manager. Then I was able to go to the fingerprint settings. I removed the old fingerprints and started to add those again. It was working fine e with the first finger. It asked me for backup password, so I added, asked to confirm the password, so I confirmed. Then I pushed the ok button and got the same error again: "An error has occurred with the fingerprint sensor. If this message appears repeatedly restart your device.". Since that clearing app data in application manager cannot help. I have already performed a factory reset and still have the issue. I have not experienced it on 4.4 Kitkat while I was using my phone for a month after i had bought. It cannot be a hardware issue. Please advice if and how it can be solved officially at home I would rather skip having my phone at being repaired by Samsung fir even weeks, but I need the fingerprint scanner working, I really like that feature. Is it a widespread common issue? Anyway I could see same error was reported on the internet last April as well so it is not a Lollipop specific issue. Any expected bugfixes?

Hey there! I'm so happy that I'm not the not one with this issue. Even I have performed a factory reset and even downgraded to 4.4 kit kat but still the problem is there.

Doesn't it inehere loosing of the warranty? I am familiar with android, I was using custom roms and rooted phones in the not far past too, but I would still prefer not to jeopardize the Samsung warranty as we have that for f.e. such situation.

Hey have you tried dialling *#0*# in the dialler and trying to test the finger scanner from there. When I do that no result shows up. Not sure what's causing the problem.

I am not sure what should have bern seen there, though both the "NormalScan" and "SensorInfo" at the "FingerPrint test" shows me title "FingerPrint test" and below that "Ready", but nothing happens. Any idea?

Having the same problem but I know why. The guy I bought it from flashed the ****ing **** out of it and nothing really works anymore.

When it says ready you should swipe your finger down - if something shows up that tell you that your finger scanner is working.

If you are rooted, I would do a nice backup and start fresh (factory reset).
Random bits of leftover data are usually what cause little annoying bugs like that. Also for the battery, use a wake lock app to see if any app/service is constantly waking up the device, and not letting it sleep

Nope , not rooted, never was. i update when the notification came and that is all. I did two resets and still the same.(all of them were "clean" resets , meaning i unselected the option to restore all my data.)

Hmm.. So you updated over WiFi? Like the ota? Since you have already reset, I would flash the phone stock 4.3 using either a toolkit you find here, or through fastboot if you have the know-how.
Because doing a wipe clears data, but if there is a problem with the actual system files you need to reflash it

Hello,I have the same lag?
Anyone else have noticed this?
Yes, I've got the same problem. It took so long the other day that I missed the call completely.

anyone have an solution?
First thing I would do is a hard reset - A pain I know, but doing so you can check whether it is potentially a Hardware issue with multitouch/touch etc.
Once you've done that, if it's still exhibiting the same behaviour check your screen behaviour on touch reactions on normal day-to-day use. There may actually be an app for it. (the Note 3 suffered some touch problems, not saying the S5 has them but have to check to be sure) .
If it is deemed a software glitch and a reset fixes it then you should be OK. - However if it's a touch screen bug I'd suggest returning/swapping it.
I'm more inclined to believe it's a software glitch, and a factory reset will indeed solve the problem.
Oke,thanks
Same issue! Did a factory reset but didn't help. Send it to local service center, they keep telling me there is no issue with the phone and that when it happens I should record a video as evidence of the problem. So much so Samsung warranty! Plus I have encountered ransom reboots when answering the phone.
Totally unhappy with S5. It is terrible. S4 and S3 were very stable.

i did noticed that too..
on mine if you put directly your finger in the circle and drag it works 1st try..
i still didnt have time to hard reset to be sure..
I noticed this too. I find that you have to hold your finger on the green answer and slide slowly. It's definitely a software problem that will hopefully be fixed in an update.
Factory reset makes no difference as done this for another problem I was having.

Don't suppose anyone has found a solution to this yet? Or any alternatives to the stock dialer that might perform better?
I also get a lag between selecting a text field and the keyboard popping up which is very frustrating. Had expected more from a brand new phone
I had this problem at first as well, but after the latest update it fortunately disappeared, I did a full wipe as well.
Same problem here! Partially solved with enabling home button to accept calls....
Same here....its a pain in the ass ?

I disabled the lockscreen animation and that helped making the device more snappy. Here are some more usefull tips http://phandroid.com/2014/04/25/samsung-galaxy-s5-first-14-things-to-do/.
I also have this lag when I'm trying to respond. It only woks on the 2nd attempt.
There's definitely a knack to answering a call, which can be quite annoying. Cannot understand why they didn't just leave it alone. Would rather answer my calls with a quick swipe to the right.

[Q] Swipe + Pattern to Unlock

Hey all,
So went from the S3 to the S5 recently and have noticed one thing that sucks about the change.
I can no longer use swipe + pattern for the lock screen.
I have setup just pattern unlock, which should be fine, however, one thing I have noticed is, the power button is often bumped in my pocket and this makes the lock screen available...
Then, to make matters worse the new screen is soo sensitive, it starts swiping patterns all over the place in my pocket! (or trys dialing emergency numbers)...
This was never an issue with the S3 when I had swipe + pattern (or very very infrequently was).
Because you had to make it past the swipe to do anything else, and it was only once in a while that it would make it past the swipe.
Now, I could enable just swipe with the new phone, but, two things, I then have zero security and when it does unswipe, it will do who knows what with full access to the OS.
I would love to get dual lock back, is there anyway that people know of?!?
Any help would be very very appreciated!
Aaron.

Flickering screen only when playing videos

Hello everyone,
I have my i9500 for about a year and had no problems until now ... the problem started around two weeks ago. whenever i play a video (it happens on any player including youtube app) the screen starts flickering (it never flickers when you do anything else!). I wanted to know if anyone has seen this and if there is a fix for it.
thank you for anyone who can help
I have seen it before and reboot the phone fix the problem.

Go to Settings, More tab, Developer options (if it's not enabled please google how to enable), Force GPU rendering
I found this fixed it in my S4 Black edition.
If this solution doesn't work for you then also try to clear the cache partion.
To do this, Hold power, home and volume up until the phone shows [Samsung Galaxy I9500 blah] then release only power button. you are now in recovery mode. use volume buttons to scroll to the correct option (clear cache partition, i think) and press power to select it.
Then reboot. Hopefully this will work for everyone.
Fix for screen flickering upon video playing
I just got a brand new s4 i9500. And when I play videos from YouTube, whatsapp through Samsung player or vlc etc my screen starts flickering like crazy and then blacks out.
To fix I went to developer settings and enabled a function called " Turn off hardware overlays"
This instantly solved the problem of the flashing screen during video playing.
Hope this helps.

Galaxy S5 Randomly Corrupted

Monday morning my device working great. Then randomly my finger print scanner stopped working. I also noticed my SD card is no longer working, says it's corrupted and asking to format. I now have to access my phone via a pattern and for some reason it is VERY slow to show the screen after pressing the power/home buttons. I cannot install any applications, and alerts me my device is running out of storage even though there is 500MB+ remaining. It's now also very slow in response.
I tried checking the finger print scanner settings but alerts me that and error has occurred and to restart the device. - doesn't work..
I've had my device for two years and never has an issues.
Device is rooted but still has stock.
Model: SM-G900P
Kernal: 3.4.0-9634333
Android Version: 4.4.2
Software Version: G900PVPU1ANCB
I also want to mention that I got a text message the other day saying that I'm eligible for an upgrade from Sprint... Day later phone starts acting up. I'm sure restoring the phone or installing a custom rom might fix this, but I'm wondering what would cause this.
Thanks
Try booting into recovery and clearing the caches, often cures random problems like that
500Mb is not a lot... I would back up your SD contents, format it like its asking, then put your backup back on it, low space would certainly explain the lag and what not, not too sure about the fingerprint scanner though.

Perhaps it is some sort of virus or malicious attack on my device?

Didn't install anything. Really just use my phone for text, email, and calling. It's really bizarre. I think I'll just have to back up and restore or get a rom.

Did you try my above suggestion? If you're open to it then yes, I would factory reset.
