Flashlight is not working. Not even when using the camera - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi All,
Just wondering if anyone have this issue? Initially the light was intermittently working on the flashlight app but when using the camera was fine. Now the light totally doesn't work even on the camera mode, even if I set as forced flash, it won't work.
This is what I have done: -
(1) I tried a full system hard reset and tried without the installing any updates or applications and still It didn't work.
(2) Booted up in safe mode and tested the light, it does not work.
The phone is N910G and running on unrooted stock 6.0.1
Anything else I could try?
Thank you everyone.

[Q] Auto Screen Rotation went dead

Hello all,
My Iconia A500's auto screen rotation just suddenly went dead on me. Flipping the lock toggle near the volume buttons on and off doesn't do anything.
I've tried resetting the device via the reset button, factory reset it via the settings menu as well as the recovery menu (oh yeah, it's rooted, currently using thor's CW recovery v.1.5). I've also tried installing another ROM, deleting the cache partition and dalvik cache, fix permission, all to no avail.
I don't think its faulty gyro since I can still play NFS just fine. Its just refusing to auto rotate the screen.
Any of you guys ever experience this? Or maybe have any ideas I can try out ?
Thanks in advance!

I did, just to see if it can fix the issue (the auto rotation went dead while i used a rooted stock rom). why?
Oh, I'm aware that Thor's newest ROM doesnt support the hardware autorotation toggle. I've tried the software toggle without any effect.

Samsung S4 GT-I9505 touch lights doesnt work after update

Hello! I have a strange problem after the last update of Android 5.0.1 Somehow the touch light buttons (those near home button) doesn't work at all.
What can I do ? I flash the ROM, wipe everything, nothing seems to work.
I open to suggestions or if the is app that could fix this let me know!
Thanks in advance
I'm having the same problem but I'm not sure if its because of the last update or not.
I'm using an app called Back Button to workaround this for now.
Would also be interested in other solutions.
I have the same issue too but after a factory reset, touch light work

Sensors Broken after ROM Change

Hi, i'm cross-posting this for visibility.
So, i'm completely lost. I was playing around with ROMs and mods (the RAM build.prop, for example), and now all my phone's sensors seem to be stuck.
I have reflashed back to completely stock ROM, taken official sprint update. Tried modded ROM, done factory resets, cleared/wiped everything, and still the issue persists.
It would appear my Gyroscope, Accelerometer, Proximity Sensor, and Compass are all not responding at all.
Right now i'm on rooted stock AOJ6.
Does anyone have any ideas? Maybe a corrupted sensor properties file or something similar like that? I'm completely at a loss.
Any help is appreciated.
Guys, it fixed itself. I booted into safe mode, restarted and all the sensors are working again.
I doubt it had anything to do with safe mode, as the sensors weren't working in safe mode.
I have no idea what could have done it. I wish I had a real answer for you.

Do not disturb not working

Hey guys,
I have a strange issue. Namely, every time I wish to access the Do Not Disturb mode, the Settings app force closes. All other settings submenus work fine, but this one does not for some reason. I am running on fully stock 6.0.1. build number MMB26K.G928FXXU2BPE6.
Any ideas as to what I can do, except a full software reset, or even a ROM re-flash over Odin.
Thanks!

[HELP] stock camera app auto focus not working

As the title says, the autofocus function on the camera doesn't work anymore. The way it works is like it's stuck on 'macro' mode, changing to manual mode and manually trying to focus further distances doesn't work.
I've already reset the device to factory settings, but it still persists, which leads me to believe it's either hardware related ( not likely at all, the only time I dropped the phone was 2/3 days of getting it in oct2017 and only got a crack bottom screen part ) or software related (but at a rom level, i've noticed it a couple days ago after updating to february sec. patch).
I would like to not get dirty into modding the phone and installing custom roms, but, I can get to do it (thinking something like LOS would be a good fit) as I've fiddled with other xiaomi devices before and what not ( and if that fixes it ).
Here are some results of the photos taken for now...

PS: It's been a while since I've got my hands dirty with installing custom roms and what not, although not everything is unknown to me for this device ( I've unlocked the bootloader before, and know what happens when I'll need to unlock it again, etc... )
Edit: just noticed my sig says i'm with Oreo, but I'm with Pie (5-feb patch).
Portrait mode works?
Try stock rom installed in fastboot mode

Yep, "depth" option works fine. even using the wide angle sensor works... it's like it's stuck focusing macro, and what's even more odd is manual mode not working too (if it was a bit of dust on the lens or something like that, manual mode would "ignore" that)...
Do you have links for fastboot stock android pie rom ?
No, sorry, just use search function.

I have the same problem, can you solved it?
