OnePlus 3T won't recognize Rear Camera, or turn on the Flashlight - OnePlus 3T Questions & Answers

Okay, so here's what I've tried to fix this problem, and I'm still drawing blanks. Here's the problem - the phone acts as if there is no rear camera whatsoever, nor led light on the back for a flashlight. Selfie (front-facing) camera works as intended.
1) Clear Cache on app.
2) Multiple different camera apps

}
- no change
3) full factory reset - no change
4) Aftermarket ROM - LineageOS - no change
5) installed brand new camera purchased new from witrigs - no change
6) Z-Device test
Weird that it shows front facing (secondary) camera isn't working, but front-facing works fine. If I try to save a z-device log, the app crashes every time. And this is a fresh install.
There was no inciting incident or anything done to the phone, no fall or water damage or anything along those lines. I'm running out of ideas here, what else can I do/try to get this thing working?

So I've just spent the past couple of hours trying to make that work. No luck on SO many steps. I imagine it's because the phone is not bricked? Is there another tool that would potentially accomplish the same thing?

This unbrick guide can be used even if the phone is not bricked.
What steps gave you problems?

Apps storage problem

Hello,
I'm not here to complain about the "Other Storage" problem, but a similar one:
I manually flashed my Lumia 920 with NCS and, of course, the cloud backup helped me to restore the application and all the rest. Unfortunately, my Whatsapp and Viber conversations didn't backup themselves, so I lost all of them and don't know why (this was a big problem, but not the main problem i'm gonna talking about).
The problem here is that all my apps now fill A LOT of more space than before (I attach you some pics so you can see). I decided updated to Amber and GDR2 last night hoping that would solve the problem but it did not.
Any idea?...

The application installation packages are stored on the phone (Not deleted after installation like any other phone, causing a massive expansion in file size. This might go down over time (WPCentral says GDR2 fixes this issue), but this isn't very likely.

[Q] Fingerprint Issues

I tried setting up my fingerprint and get this error. Phone is up to date, tried factory reset, clear cache, and rebooting like it says. It is still broken. I called t-mobile, and the tech said it is a known issue and to wait for a patch. If it is known, has anyone else here seen this?

I've gotten same error. I've stopped using the fingerprint security for that reason. I've noticed it doesnt recognize my fingerprint all the time.
Just seemed buggy to me, its like i have to place my finger carefully in the similar manner i did when setting up the fingerprint.
A someone who has worked on fingerprint scanners of all kinds, while it could be a samsung issue, it is also possible the fingerprint scanner is not picking up your fingerprints if they are too shallow. This is a common issue. This can actually happen.

Are a couple of easily googleable instances of this.
The best suggestion is compare to someone's working fingerprints as a way to be sure its the phone and not your fingerprints. Hope that helps.
This happens as soon as I press the fingerprint button under Security settings. I can't even attempt to register one.
Yeah sounds like a hardware issue. I'd get an exchange

Get it replaced. My iPhone 6 had the same issue and Apple said it was a faulty sensor. Those things are very touchy.

N920T Home screen size distored

Hey everyone, I've got an issue I've been trying to get figured out with no luck & I'm hoping someone can point me in the right direction. As it says in the title I'm on the Note 5 32GB from t-mobile, it's running 6.0.1, and is rooted with TWRP recovery. Now on to the issue.
Yesterday I rebooted my device, and when it came back up the home screen shrunk. What I mean is the icon/folder area and the screen indicator dots are smaller causing a significant dead space area between the dots and my bottom bar. I have included two photos, one untouched and one with yellow highlighting illustrating the area I am talking about.
In an attempt to remedy this, so far I have done the following:
Checked that one handed operation is disabled (it is)
Checked and changed screen fonts & font size
Changed the home screen grid options
I've even went as far as doing a system reset in twrp erasing everything and starting over
With that I have been unsuccessful in getting this fixed. I am hoping someone can help. In my research the only information I have found to this point talks about the settings I listed above as attempts, and I haven't seen this problem come up at this point, so please don't blast me if I've missed it, and you know where I should look, I am more than happy to read any information provided.

I've shared the photos with an image tag from my onedrive account, if they aren't working please alert me and I'll try to find another way to share them.
Not working. Curious though. How is the rest of the system? Setting and whatnot set to normal? Did you flash a ROM?
Sent from my SM-N920T using XDA-Developers mobile app
Everything is default accept my theme, which changing it didn't affect it either. It's a stock rom and systemless root with TWRP recovery. I was thinking I screwed up a setting also which is why I tried to do a reset.

as you can see, everything is dark and the white circle is my light
ive looked up on why the camera could be bad but it seems like people are only asking about the red circle or the loss of drm keys
ive tried wiping dalvik/cache and cache but same thing
i flashed the latest rom/arm 6.0 pico gapps/supersu/xposed

Hard-Bricked OnePlus 3T – Managed to Install Successfully with MSM – But Black Screen After OnePlus Logo (Only Access to Fastboot)

Hello,
I've successfully managed to install OnePlus3T_28_A.86_191104_repack through MsmDownloadTool V4.0.71 where the Status of Communication is "Download Complete".
{
"lightbox_close": "Close",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After this, when the phone boots, the OnePlus logo shows up for a little while – and after that, a black screen. I can only access fastboot – and that's about it. The phone is locked, etcetera, so I can't flash via adb/fastboot. When I try to access recovery mode through the fastboot menu, the screen becomes black too.
Worth mentioning I've also successfully installed through an older version of MSM before this. But same results. The version is the following OnePlus3T_28_A.23_161027 and the MsmDownloadTool V3.0.6.
What are the alternatives? Is it good game? If someone could pinpoint me what to do next would be glorious. The hard-brick guides seem to always point to the MSM way of things.
Thanks in advance!
Alright so I've been digging a bit deeper.
Stumbled upon a bunch of different YouTube videos that had similar solutions.
Most of them were squeezing, tapping and doing different motions onto the phone. Like pressing down the screen at different angles with some pressure, etc. Also from the back, the buttons to loosen them, etc. I'm sure I've missed some of the methods mentioned in the video.
However, the squeezing on the screen and the back actually made the phone go past the black OnePlus logo into the boot animation -- and I thought that was it. Apparently, it hung up half-way through.
The last method they mentioned was to put the phone in the freezer in a zipper bag and TRUTHFULLY it worked after being in there for 10 minutes. The phone booted up, went through the installation setup and it worked for a while... until it didn't.
Apparently, my battery does not charge and it's stuck at 0% all the time. Seems a bit suspect. Will dig further into it.
