[Q] [Help] Front camera not working i9500 - Galaxy S 4 Q&A, Help & Troubleshooting

Hi I own a galaxy i9500 (kitkat)! Every time I try to take a photo with my front camera, my phone freezes , and a warning box appear ("camera fail").
All this start to happen after i get my phone rooted, i ve been reading a lot, in many places i ve told that could be hardware issue but, im almost sure is something related to software o camera firm (i really hope that! I live in argentina and the camera replacement is really expensive and hard to get).
i search in google and i get some firms to update another smartphones, but nothing for S4, im really noob so hope you can help me.
Hope you can help me with this, if you have this problem and you fix it tell me how!

Try flashing a stock firmware with odin (plenty of guides available on site).
Once everything is stock then see if camera is working, if it is then was a software issue if not working then its hardware and a repair maybe in order.

Did you remove all knox related apps after rooting?

Could someone plz help me out with my Wizard's camera?

Haya everyone.
I am really lost for a solution here.
My wizard's camera has stopped working properly.
It used to work fine, but since recently everytime I want to use it, the pictures come out all screwed up.
I've attached two samples below.
I tried just about every camera patch there's available, but none of them seem to have any substantial effect.
I also tried different JPG settings, different sizes(that worked a short while) and even different Camera applications like coolcamera..
None of them seem to solve the problem.
Anyone have an idea what the problem could be?
Tnx a bunch, just really annoying I can't even use my wizard for sending mms....
Everything just looks wierd...
plz help me out here....
I've had a very similar problem with my old non-smart phone, I took it in to the service center and it was a hardware problem... I hope I won't disappoint you but if it hasn't happened after a ROM flash, camera software change or something - probably your camera is just broken, anyway you can check that in your local service center too?
ehhh.. it is simple settings prob imo. do full backup and hard reset to be sure.
Noob question
Tnx for your reply..
I don't think it's a hardware issue, since the preview of the camera is good.
I'll try a hard reset, but could anybody tell me how I cab perform a full backup?
Sorry for a noob question...
I use SPB Backup. It has been working fine for me untill now, and you have the chance to restore e. g. only pim.

Sensors and MCU not working

Hi guys,
New owner of a S4 (GT-I9505 international) here with a problem. 2 days ago I noticed the screen wasn't rotating anymore. I used to rotate it portrait/landscape in applications like Camera or Internet (browser). The moment when it started to bother me was when looking at pictures with the phone in portrait and the image was landscape. Trying to rotate the phone didn't help. It was frozen. I called a buddy of mine who has some experience with Samsung devices and told me to verify the "Auto-Rotation" settings. It was all OK and enabled. Then he suggested turning the phone off and pulling out the battery and SIM card for 5 minutes and putting it all back. This didn't help either. Finally we got to the point where he told me to enter *#0*# in the Phone dialing application. As you might already know, this code gives you access to the "testing" hidden utility. There I tested all the options available. Everything was fine except for the Sensors and SensorHub Selftest.
In the Sensors section, all the tests failed, starting with the Accelerometer and ending with the Temperature. I uploaded screenshots taken during the tests. Please remember this started 2 days ago. Before this it was working perfectly. I don't recall making and major changes like updating any OS components or installing/running stress utilities related to sensors or device behavior. After doing some research online and reading about other people's similar problems I got to the point where I started to suspect a problem with the MCU (Micro Controller Unit). This component, according to Samsung, controls all the sensors and reads raw data from them without accessing the AP (Application Processor) this way extending the battery life. I believe the problem is here because it seems odd that none of the sensors are working all of a sudden. Can this component put the sensors into a sleep state and shut them down completely? Might this be the case here?
Below are the solutions I tried in order to revive the MCU and finally the sensors. I was all without success:
1) Turned off the phone and pulled the battery and SIM out. Put the back in after about 5 minutes. Result: sensors not working.
2) Reset to factory-settings from the settings option while the phone was in the working state (turned on). Result: sensors not working.
3) Rooted the phone, installed Clockwork Recovery, made a full system and applications backup and then installed custom ROM (two actually: PACMan, Google Play Edition (4.3)). I did this in order to exclude a problem related to drivers in the stock Samsung ROM, even if it was logical that Samsung being the owner and manufacturer of the device might have the "best" drivers and applications for inquiring the device components/sensors. I am aware this ended the warranty for me, but can I know it can easily be undone. Result: sensors not working.
4) Restored the original stock Samsung ROM. Result: sensors not working.
The utilities used for sensor testing were: Sensor Kinetics and Sensor Tester. Both can be found in the Play Store. On my wives phone, which is an old HTC Desire, both utilities picked up the available sensors and created graphs with the results. On my S4, I only got blank charts/graphics/results. In Sensor Kinetics for the Gyro for example, the message was "Waiting for the Gyroscope sensor...", just that, stuck.
If there are any other guys (or ladies!) out there who encountered this awful experience, please reach out and tell me if you found any practical solution, any other then just taking the device back to warranty. I'm open to any suggestions.
Best regards,
Andrei
Most likely a defective device ... can't you claim warranty and sent it back?
Sounds like hardware failure. This would be an issue for Samsung to solve.

Unfortunately I bought it second-hand and it does not have any warranty. I guess it's one of those moments I wish I had patience and gathered more cash to buy a new one from the store. Anyway, it's my bad luck. I had it working perfectly for weeks after buying it. I will use it like this for the time being..
i´ve got the exact same problem since yesterday...
i think i´ll take it to the shop for warranty
I've got the exact same issue. All sensors are having the same issue. None are working,
I found out because my camera app was not switching between landscape and portait any more. All pictures are saved as landscape...
Called Samsung Netherlands and they told me to wipe my phone (still latest original stock ROM) and try again.
Making a backup now using Kies... and will hard reset it afterward and check the sensors.again.
Probably not going to work... So I have to send it in...

Hi there. I had same problem with sensors and MCU test failed, so i took phone to service. They said its hardware failure and replaced main board. Im picking phone tommorow and we will see...
Hi guys,
I took mine to a local phone service, not the official one, but they are an affiliate. They could not figure out exactly what the problem was so they replaced the logic/main board just for testing. It was all working fine. They called and informed me of the findings. Given the fact I don't have warranty for it, they suggested to send it to our main service in Bucharest where they have a more sophisticated testing equipment. It is possible to get a more precise answer regarding the defective component and maybe a less pricey solution to the problem. At this time, the only viable option is to get a new logic board in place, which is about to set me back 250 USD. I will get an answer from Samsung in Bucharest by tomorrow or the day after tomorrow.
I will get back to you with my final solution... hopefully something not so expensive
@darklord, @eweu: please post back you findings. Maybe in the future when some other unfortunate owner finds his way in here, will have a better understanding of whats on the plate for him.
Thanks,
Hard reset did not work as expected. Going to drop it off at a local official repair center....
S4 Sensors failing

After installing some other ROM's and playing with different CSC's I have no sound and even no wireless and only Edge speeds on some ROM's. Restoring from backups, wireless came back and HSDPA+ also, but no luck with sound what so ever. Now, I have a tablet more or less. Thanks Samsung, this is great!

I have the same thing here
all sensors are broken because of SensorHub BIN FW Version: AT0199999
then i try to update firmware with *#2663# it failed.
I have the same problem with my S4 GT-I9505.
Suddenly the device do not auto-rotate, and no air gestures with gyroscope and accelerometer are working.
The SensorHubTest end with FAIL.
Mid december I got one OTA firmware update and I didn't notice any problems first.
A few days after newyear I notice that my auto-brightness adjustment did not work properly.
Can't remember if auto-rotate didn't work when I notice the auto-brightness problem.
But finally I am here because I searched for sensors problems.
I did the SensorsHub Test with *#0*# and it ends with FAIL.
It seems that there is a problem with the 4.3x firmware.
With 4.2x all was fine.
Can anybody confirm my thoughts - that the firmware is broken and not the MCU itself?
What can we try? Downgrade? I read that one was lucky with "factory reset" but it didn't helped to revive the MCU of my device.
Thanks for reading
and answering

Hi, i am a owner of a sch-i545 phone, and i have the same problem with the phone: no response of any sensor and a fail on test (or upgrade firmware) of the sensorhub.
At this time i was tried a lot of solutions: i was flashed stock firmware, custom firmware, and of course a factory reset (by the way, the first time with this problem was when i did it a single factory reset), its still broken the communication with the sensors.
I get back to life the phone when i upgrade the phone from 4.2 to 4.3 (sadly) and get lost when i update the binaries in super su (previously rooted with vroot).
Yesterday i give the phone to a technician (a close friend of another best friend), he will test the phone on this weekend to determine what is the problem to try to fix it.
When He fix this phone, i will post any news!
Regards.

Thanks for your answer. I have hope that the next firmware will fix it.
What is strange that none of any reseller/privers know this problem. It seems that also Samsung has no knowledge about this special error.
Well if the next firmware didn't fix the problem, I can replace my model with a working one, that is what the guy at the phone shop offers to me.

Same Problem Here
Hi guys, I'm new to this forum so be nice :angel:
I am having the same problem in that none of the sensors are working which indicates that it is a connection issue or the actual hub not working or the firmware and not the individual sensors themselves. I have thought about this and looked around and to me it seems like there are only 3 possibilities for the problem:
1) The SensorHub BIN FW Version is out of date and needs to be updated manually (not through *#2663 as it doesn't work)
2) There is a connection issue e.g. the cable from the sensorhub to the motherboard is loose or broken
3) The sensorhub is broken (not the sensors)
I will try to find the firmware files and see if I can do a manual update. If that fails I will open up the phone and see if the cable is connected/broken. If I still cannot solve the issue, I will have to take it to the shop and hope I can fix it off warranty (I bought it second hand)

Thanks Dan for your reply.
I assume that your S4 shows the same behaviour as my one and the phone is still working fine.
The sensorhubtest failed and your light sensor for automatic adjusting and the sensor for turning the display are not working.
What is really strange that I went to a vodafone shop in Hamburg and ask them if there is any other one having problems with the S4.
You know the answer? They where wondering and telling me that this is wierd and they heard the first time of such an issue from me.
I showed them the device and showed them how I test the sensors. *#0*# funny they didn't know this combo
I hope that you succeed and share your knowledge,
with best regards.

[Q] Touch screen problems... not registering touches properly

So I really hope that someone can help me here as I seem to have a big problem... I'll try to write this out from the beginning...
Ordered my phone from Hong Kong. It is a D802 model. 3.4.0 kernel, d80210b software 32gb (likely the HK version right?). I knew that it was upgradeable to kitkat and so I downloaded the LG mobile support tool and plugged in my phone. I set the country and region to UK and set it to upgrade the software. Then I let it do what it does. At the end of the process the phone was stuck in bootloop on the LG screen with the indicator light switching between blue and green.
I then tried to fix it using the LG flashtool, but it wouldn't go into download mode and went to fastboot. I figured that it was stuck in fast boot and so I did the laf.img fix that is out there to try to restore download mode. The laf.img file I used was for a 16gb D802, not a 32gb like mine. I'm wondering if that is what created the issue that I have. Anyway, this allowed the phone to start in download mode and from there I flashed the software to Hong Kong d80210b 32gb.
This is where I noticed the big problem that I am currently experiencing and need help with. My phone screen does not register my touches in the right places. If I try to tap a location on the screen (an onscreen button) it will register the touch somewhere else completely. I thought that it might be an android version issue, but I upgraded to European open D80220D_00 (it doesn't seem to specify 16gb or 32gb) using LG flashtool 2014 and the issue remains the same.
I am unable to use the phone completely and I assume that the issue is deeper than the android version. I would really like to resolve this issue somehow. Does anyone have any idea? I'm thinking that if I could force a complete re-install of everything that might fix it. I was told by a useless LG rep (over the phone) that I would have to give my phone to my service provider and have them send it off to a technician to re-install the software, but I figure anything they can do I can do as well... right?
Any help would be appreciated.
Thank you!!
Seriously, all this knowledge and no one can offer me any help? Is there maybe some driver on the phone that is bad? Where would I find that? How would i replace it with a good one? Do I replace the Kernel? I don't really know how to go about this. Any help would be great.

You may not see the replies you want because alot of times your questions have already been answered and some of us have moved on to other phones etc and no longer visit these forums.
Search....
Your problem sounds like a faulty digitizer
I appreciate the response and info.
As far as searching goes, I did, for hours. I spent my long weekend here and all over the web looking for a solution with any possible number of keywords. I didn't come up with anything.
Faulty digitizer would make sense, although it appeared to be working prior to the upgrade... I would be happy for a faulty digitizer as that should be covered under warranty.
Thanks,
Mike
so sorry to burst your bubble but i don't think its hardware prob i have the same prob as you , ppl say update ur touch S/W and i know u cant cos u cant even dial 3845#*802# to do it , i also spend 2 days trying to fix it with no luck

I am willing to bet the phone is not bricked.
Try switch it off, (remove battery and put back in if necessary).
Then all at same time press power on, volume down and home button. When it vibrates let the buttons go. this should get to download mode.
If you see that yellow triangle you can be saved.
Then you need to get a Stock rom from Sam Mobile, for your model of phone. SM910F ???
Download program called PC Odin.
The rest you will see on you tube etc. How do I flash stock rom on Galaxy note 4.
If your lucky you will have a perfectly good phone. :laugh:
Either way you have nothing to lose.. If Download mode can be reached, there is a fix for your phone.
Hey sorry for late reply,i just went to the "experts" who had somekind of "box" callef device and he fixed it for me , octopus box or something. So i sold the phone and got a moto x plau xt1562. I didnt like the touchwiz vibe anyway. Love the stock android experience.

Can't take pictures: If I do, the phone reboots

Hello everyone,
I've been experience a very ugly issue with my S7 Edge.
SCENARIO 1: When the sensor works (meaning when I can see in the screen what the camera "sees") and I try to take a picture, the camera throws an error message saying "Unknown error occurred", and then the phone reboots:
SCENARIO 2: In other occasions, the camera starts with a complete black screen and immediately throws this error:
One of the two scenarios above always happen, which basically means I'm never able to take a picture.
What I've tried so far:
1) Upgrade from Marshmallow to Nougat.
2) Reset settings.
3) Full phone reset (cache + data).
4) Phone reset from recovery mode (cache + data).
5) The issue are present in safe mode as well.
6) I tried downloading other camera apps. Errors again.
7) Tried changing the storage location from SD to Device. Didn't work.
8) Video recording works!!!!!
Is it a hardware problem in your opinion? How can a software issue still stay after a hard reset? I'm not sure because in SCENARIO 1 I can see that the sensor works, plus video recording works!
Any help is greatly appreciated!
FIXED by using ODIN and flashing Nougat with the CSC file
Maybe try flashing full stock rom through odin or smart switch since there might be a problem to the system files itself.
In my opinion though, this seem like a hardware problem.

I also think it's a hardware problem. I'm just gonna send it back to Samsung.

I've been having the exact same issue for months now. On 6.0, 6.0.1 and 7.0 as well.
Please let me know what Samsung tells you. The problem for me is that I bought the phone from amazon (8 months ago) and live in Argentina.
One thing I can't understand is that camera worked fine for the first couple of months. Also find really strange the fact that I'm able to take pictures with flash ON. Have you tried it?

I tried some days ago with the flash ON, and it didn't work (if I remember correctly). I didn't waste too much time, and as soon as I found out about the issue I sent it to Samsung for repair.
I have it back since today afternoon, and what I read from the attached papers is that there was a malfunctioning piece which they replaced. The list of operations Samsung did is:
- Boardswaping
- Software update (I doubt about this one as my phone was already updated)
I really think you should contact Samsung directly, and not Amazon. Here in Europe they have a good repair program: after max. 3 business days you get your phone back (and they will do the pick-up, and delivery). Maybe it's the same in Argentina.
Good luck!

Do you know which board did they swap? The main board? :S
Argentina doens't handle international devices. I'd have to take the phone to de US .
I'll try to get it repaired here anyways.
Thanks again por the info.
