This may be the most rare thing that happened to me on my Smartphone life.
Suddenly my LG G4 stop rotating its screen automatically. Couldn't take a photo on widescreen or see a picture... only vertical format for everything. After trying to see if it was any of the latest apps, I uninstalled them and nothing... download Sensor Box and apps of that kind, ask for help to the Kinscreen app creator (as it never show any angle of the phone near 0º) and got to a conclusion: my gyroscope and accelerometer were dead. The phone still was ok, but I could not live without the possibility of rotating it, as I use that feature a lot for my work.
After a coupIe of days trying to solve the problem, I was faced to buy a new smartphone. My choice was an Samsung Galaxy S7 Edge, as I missed the amoled screens (had it last time on an Motorola Razr I, but then LG G2 and G4).
As you may know: the LG G4 has a microsim as the S7 needs a Nanosim, but as I was not so sure about it I checked. Pulled out the battery of the G4 and then realise that I was right: I needed to ask for a Nano sim when buying the new phone on my carrier.
Once I bought the new smartphone, I was setting my screens and configuration and had both phones side by side. Tired of the process, (hours of it) I decided to take a break and by accident I lay down the G4 that I had in my hand in the widescreen mode... and then I was left to see how the screen DID ROTATE that time... So... I checked everything and find that the only possible explanation was the fact that I had pulled the sim out and back again the days before, but never checked screen rotation as I never would had thought that it could fix that!
Now what the hell does the sim has to do with accelerometer or gyroscope?
Needed to share in order for everyone to know. I'm happy with my change but I would not have done it if it wasn't for the screen rotation issue.
And that's how I'm off with the G4.
Kind regards,
Hello Leonel, it's hard to believe removing the SIM has fixed what appears to be a hardware issue. My guess is that the sensor got stuck somehow and you opening up the back cover have shaken it back to life. Either that or it was a SW error and the removal of the SIM has reset something at SW level.

If he hadn't tried to change firmware(reflash lollipop for example) you can't say it's hardware issue. Sensor showing 0° isn't always right as software is responsible for sensors to work. If software fails you might think that it's hardware issue, I had similar experiences this year with my Galaxy s3. Flashing latest KitKat firmware helped it and it worked like a charm

more and more often my wife's S4 will turn into a black screen with the time at the top of screen...this will happen at random times she says, checking texts or looking at gallery pic's.
she has a generic phone case with a magnet to close the full cover (not a windowed cover.) BUT, like me, she leaves this full cover open (bent backwards and the magnet holds it that way) ALL of the time. i'm thinking the phone decides to go into Sview mode or something?? is there a way i can turn this feature off, or fix this problem another way??
BTW, she is running Android 4.4.4
thanks for any insight! --- art
bump?
Seems like you should be able to turn it off somehow. However, it might be a software issue in the case a data factory reset should fix it. If it's a hardware issue then I would take it to my provider or Best Buy to look at it.
i removed the case yesterday and it hasn't happened ... yet! hopefully that fixed it. thanks for the reply Stoney!
Similar to this problem for the S6 Edge:
http://forum.xda-developers.com/galaxy-s6/help/magnetic-sensor-compass-problem-t3109583
When reboot the device, the compass/magnetic sensor is not calibrated. Once I dial the *#0*# and then chose the sensors, and rotate the phone on the 3-axis, the magnetic sensor becomes calibrated, the number 0 and red line becomes number 3 and blue line in the black circle. However, if I decide to reboot, have to do it all over again, have to rotate the phone on the 3-axis to recalibrate the magnetic sensor.
It seems like the problem still persists on the S7 Edge, am I the only one?
Thanks,
JP
I have exactly this same problem on my S7 edge in Australia from Optus - compass re calibrated then when off and on again it needs doing again every time. It looks to me as if at least some S7 edge may have inherent compass sensor or software issue. I will try and replace it via shop but they said it may take many weeks to get a replacement once returned if out of stock as they would need return it to somewhere to check it...

I'm wondering if they are not all the same the S7 Edge, seems as if this was the case with my S6 Edge, almost everyone had this problem and Samsung wasn't doing much for it.
It seems as of this is the case for my wifes S4, my S6Edge and now my S7Edge.
Can anyone else confirm this? It's as easy as rebooting, then dialing *#0*# and then under Sensor...
I'm having the same problem on my S7 Edge.
Optus, Australia.
Maybe it's Exynos only, and SD don't have this issue?
My compass wasn't calibrated when I checked. Now is. Need to check if GPS works better now.

You'll loose your calibration once you reboot the phone...
How do you calibrate the sensor?

You rotate your phone along the 3-axis until it's calibrated
I do not believe this is a problem or issue! You need to calibrate each time you reboot. The same thing applies to the iPhone (blah!)

You think? It could be the case, as my S6E as well as my S4 do the same thing...

Never had to recalibrate on any of the three iPhones I owned. And certainly not on the 6s Plus I used before getting the s7.

Well you are right about the 6s as I just tried it. I don't think I even opened the compass on my 6 but after every restart on my 5 and 5s I definitely had to re-calibrate after a restart. Might be because I was jail-broken though. No idea then, hopefully someone who knows about the actual electronics may chip in...
Hi. Has anyone had an issue with the compass being very jittery after it has been calibrated?
When I reboot the phone, the compass works fine and is stable unless I calibrate it again. It is my second S7 Edge and I have had the exact same problem on both devices...
i've read the s6 thread and did the *#0*# thing and works!
(for those too lazy to read the link, basically press *#0*# on the call screen and it will bring up the "tests" screen
press the sensor
and will see the bottom, the status of the magnetic sensor
if it's not blue and has number 3 , than it's not "calibrated"
to calibrate, do the 3-axis thing (rotate the phone on 3 axis: turn it upside down height-wise, flip from side to side length-wise, twist it depth-wise) and the sensor will turn to number 3 and colored blue line)
(to exit which ever screens, just double press "back" button on the phone)
but my question is... (for those who've done it) seems like it has to be done (calibrate) on this "test" screen? can't calibrate if it's not this test screen?
Same here. Frustrating to need to recalibrate after reboot. Was the problem ever resolved with the S6 or should I just accept and learn to live with the issue?
this (calibration loss after reboot) was the case for every android device i owned so far since years!
so this is normal, and cant and wont be fixed!

I did not have any issues with my original HTC One, G3 or OnePlusOne. But, I guess it's going to be a fact-of-life.
Galaxy s7 edge
So i found the answer guys to fix searching for gps and gps not working. Running samsung galaxy s7 edge, also with optus but that doesnt matter. Soball you need to do is calibrate your phone, now you can download apps but if you use the built in app that comes with the s7, it works better
Step 1. Swipe the edge notifacations to bring up side display.
Step 2. Go into the settings, by touching the clog on the bottom left.
Step 3. Tick the widget for the compass, ruler.
Step 4. Go back to the home screen and swipe to bring up the side display.
Step 5. Go to the compass widget and in there, there is a calibrate button to click on and complete the calibration by spinning your phone on a axis as displayed and your done.
You wont have to redo it each time you restart like the other ways i have seen. I have contacted samsung about this, hopefully they fix this stupid issue.
My fingerprint scanner has stopped working, after I upgraded to Android 7 (Nougat).
I took it into my Samsung store who said it was a hardware issue, it failed the self diagnostic test.
However they refused to fix the issue under warranty because the screen is cracked.
The screen has been cracked for over 5 months now, so I hardly see how they are related.
Can anyone way in on this?

Well if the screen is cracked, and your phone is still under warranty, then surely they should be fixing that too ? Samsung sound pretty useless to me, and use every excuse under the sun for not fixing things, try boot to recovery and factory reset, this can sometimes fix faults after an update.
EDIT: after updating mine to androind N, the fingerprint reader is working fine, infact so far ive got no problems here at all.
Yep a long as it is a UK model and under one year old Samsung should change the screen and fix the touch sensitive button. As long as you don't have a great big dent in the case that caused the cracked screen...... I just ordered new back cover for mine as it's a dual SIM and Samsung won't repair it under warranty. They quoted £65 to change the back cover and I purchased it on eBay for £20.
I will heat up the back cover and change it myself tomorrow.

Try to go back to MM.
Download latest MM version from sammobile.com and flash it with Odin
Then you will know if it's SW- or HW problem

s7 edge fingerprint sensor error
Wanted help regarding my s7 edge fingerprint sensor. It responds just fine sometimes but most of the time it gives an error. I tried the solution of clearing cache , pressing power and volume down button together to soft reset it. But nothing worked. The funny part is that it will respond for a few while after rebooting ( restarting ) it but when it gibes the error it stops completely until restarted again. Did not drop it. Didn't place it in water. The problem did start after updating from marshmallow to nuogat and even after getting two security patch updates. Don't know what to do. Can anyone plz guide me how to use *#0*# code to check fingerprint sensor because when i check it it sometimes give that intializing failed. Sometimes if i don't put my finger on the sensor it says it passed and when i place my finger it only shows first box passed while the rest of the boxes fail. I searched everywhere on internet for but in the end came back to xda and decided to ask u guys. As i did got alot of help from u guys on my s2 and note 4. I hope that someone might try to help.
I don't know the answer, but I can confirm a similar issue with my S7 since upgrading to nougat. Also I seen to get a few apps force closing. My device is stock and not rooted. I got so fed up with the finger scanner not responding I switched back to only a pin code for a week. Now I switched back to finger print and only set up one finger print memory........now for a week it send to be working, but still getting force closes of the play store app.

Try to reinstall the rom stock. If the problem persists, then it is a hardware problem. Your sensor went to the bag.
Hello all.
First of all, sorry for my English. After few years of good perfomance, the LG G2 D802 with stock mod started to perfom slowly like a film in slow motion, e.g.. it takes a second to show each character in the screen that i am writing now. In addition, when the display turns locked it is impossible to unlock it without reseting the device.
I tried with a hard reset but the problem didn't solved. The superuser android test for the proximity sensor passed ok (I think). Have you seen this before? Can anybody help me with this?.
Edit. The poperty high temperature off enabled maybe let it run a bit faster but still with long delay. A few times the device starts to work as fast as it was new but this situation is for a little while, an incoming call or similar returns the device to the "lag" mode.
It is amazing, now the phone runs like the first time, seems unbelievable it runs better than ever, after battery charge but I havent done anything special ... So at this point it is a hardware or a software issue?
Android version: 4.4.2.
Kernel: 3.4.0
Soft. D80220h-EUR-XX
Conpilation KOT49I.D80220h
UPDATE: Problem returns as I expected. So I have open the cover and check connections, all seems ok but I left a small piece of paper above the proximity sensor just in case, it dint work.
Ocasionally the screen performs a kind of flickering, e.g for a few seconds I can see the top half of the screen just in the bottom half of the screen... any idea for next step? nobody is using LG G2?.
UPDATE : I have Flashed stock rom lollypop 5.0.2. And it seems that now the unlock problem is solved, but the lag remains,it is crazy, two seconds from push letter until it appears on the screen...
Maybe it seems a hardware issue, now I am considering this steps:
1) Flash kk again 4.4.2 and hard reset. Just in case, but no hope that it works.
2) if it is a hardware issue, it can be a problem with flex cable or display or digitizer or proximity sensor or motherboard or other I don't know or a mix.
3) Hit the mobile against the wall
At this point, Did anybody deal with something similar?
I'm new to this forum, so I posted in general this problem I'm having since I don't know which category fits for this.
I know this forum is for software-related topics, but I've found hardware questions as well, so I guess this should be fine.
Basically, some time ago my phone started having this problem, which I suspect is hardware related, which is what they call screen burn.
Funny thing is, people usually say this problem is permanent, but in my case it's just temporal.
Sometimes my screen is working just fine, and suddenly starts flickering. If I try to switch apps, a "ghost image" of the other app stays there in the background, and until the screen refreshes, it takes time, or maybe I have to switch my screen on-off again, etc.
Another times It turns white, but I still can use my phone properly.
I've identified it's just a screen issue, because as I said, I can actually use my phone fine, but I have this flickers and ghost images. These ghost images are actually the most annoying problem when they happen.
To do some testing, I downloaded a burn-in test app to check every colour, and I've noticed that most colours work fine, but just the white and grey were weird? Like, maybe in the top of the screen the colour wouldn't show, but in the rest of the screen it was working.
Other times, the screen starts to display "colour lines" in front of everything, and after some time they disappear.
Want I want to know is, is this a hardware problem, or software? I guess it's hardware, I'd find it weird to be software.
If so, changing the screen would fix this ghost images and flickers? I haven't tried changing a phone screen before, but I can just buy one and there are videos for my model on how to change the screen so I could do it.
What I want to know is, how to fix this, and If replacing the screen would do. I honestly am against the consumerism trend of throwing away phones, so I at least want to try.
Thanks.

Hi...
so it could be software or hardware based.
first i would make a full backup and then try to completly reset the firmware and check if the issue is done
if not...it could be the screen or the mainboard or the connector to the mainboard.
at first i would try to change the screen to a new one. mostly the screen have problems. if that not work it can be the mainboard...for a buying a mainboard i would look at ebay for a completly damage devices just to remove the mainborad there and to buod in to your Device
hope that helps you

I commented my problem with a friend who studied CS with me, and he told me after seeing the phone that in his opinion it's likely the screen. I think so too.
It's ebay a decent play for buying a screen? Or better aliexpress? I've seen screens for huawei p10 lite in aliexpress

Hi...
Idk if ebay or Alie would be better. I would take a look wich one could send it fastest to me and if it is original Part or from another manufacture.
Hello, I've been experiencing same kind of issues in recent months and I'm interested how the story continued and did fixing the screen was the solution?
Thanks in advance.
