cannot connect to camera- camera error - G2 Q&A, Help & Troubleshooting

I searched the internet and saw many people who have that problem on 4.2.2 but never on LG G2. I have that error sometimes but after a restart the camera works again. Any way to solve this? What is causing this problem? Software or hardware? Does anybody have that problem on this phone? I'm on europe open d80210a software. Thanks!

Only experienced this on Stock-ROMs. CM never had this problem afaik (at least not me when I was on CM), so I'd guess it's software-related.

That is strange, stock rom suppose to be the most stable, am I wrong?
Is it possible that I'm the only one with that problem?

No, you are not the only one. I have the same issue ad I have to restart the phone to get camera works. Also, I searched internet and seems other LG G2 users have the same issue.

I looked the internet too but did not find anything about that problem with LG G2

I found that if I had snapchat open on the camera and locked my screen it would give me this error and I would have to restart, maybe it's happening in other apps that use your camera?

[Q] Hero camera crashes

i always get camera crashes on my hero when i enter the camera app or any app that uses the camera for the second time when it has been closed. it's fine for the first time but reboots the phone on the second.
i was wondering whether anyone else had this problem or has found a fix for it?
It cant be a hardware fault because it seems to be fine whenever i downgrade the firmware below 2.1, also, the camera app doesn't crash when the phone is on charge.
(it does the same on every rom i try including stock)

[Q] phone does not wake up

Sometimes, when i try to wakeup my phone using home or power button, the capacitive keys light up but the screen is black.. I have to press power button to "sleep" and wake it up again... any idea? It was like this since I got it.... I updated recently and the problem still persists... it's not a big deal but a bit annoying at times.

It may be due to firmware bug or some installed app.
You didn't tell what rom you are using (stock or custom). And also check for installed apps that you suspect.

It's a hardware defect. Mine was like this too since 11th april. After changing the motherboard to the newer, 1.1100 version, the problem is competeley gone away. It's waking up every time correctly.
We had a topic about this earlier...
Hardware defect? Are you sure? I dont have a warranty. Bought it abroad. I was hoping it was just a software glitch. I am on stock unrooted

I'm totally sure because i had this bug from the beginning. I was trying all firmware updates, factory reset, etc. It's not related to the fingerprint sensor or any app installed or not.
Ok i have no choice. Will try the solutions i read from google, seems to he a common issue

All i can say is that the old motherboard was 0.800 according to the phone info app, and the new one is 1.100 .

Camera trap with 240fps!

Hi,
The problem here is related to camera, not with my phone, but my cousin's one, whenever he switches to 240 fps video recording, the phone crashes, forcing him to reboot.
As regarding my 6P, I'd never faced such issue. I looked online, and found few people complaining about it, many of them considered replacing the defective unit. *which is difficult in my country*
Does anyone here have any kind of solution for such problem? :crying:
Has he tried doing a factory reset and make sure he's on the latest version?

I'm sure it's the latest version.
But it's a used phone *almost new* and he did factory reset before doing anything.

So, it had been resolved by Feb update?
Check Apps
I had same issue.
The reaqson was in LiveWallpaper which crashed device camera.
Another one had this issue because of one static wallpaper.
Check your apps & walppapers. You also may try to turn on Safe Mode to exclude 3rd party apps from loading.

Any solutions? I want to know is it software or hardware problem?
edit: Specs
Marshmallow 6.0.1 G900HXXSACQAA/G900HOJP1CPL1/G900HXXU1CPCA

Waouuuuuuu....
Never seen that before.
Backup, flash new firmware and reboot.
If problem still present, it's a material problem.
Good luck mate

Seems to be a standard problem. I have it too.
Internet forums are full of this problem.
Buy another phone than Samsung.

I've seeb it alot actually. I mean the wake up problem. But noone seems to fix it yet. If anyone did please tell me
Has anyone test this with older Android 5?
The "Weird" Screen in Low Brightness is AMOLED Burn-in due to intensive use, My S5 Have this problem too.
Try changing the HW overlay / Force GPU rendering in developer options, others have said that works for them, it seemed to for me also but only temporarily. I have had to stop using auto brightness.
Device not waking up is very irritating, even double tap the screen to wake has the same problem, doesn't seem to be the buttons themselves. If you have a custom rom or other way to set double pressing the power button to launch the camera it works as a workaround for me.
Thank you for all the answers guys.

Flashed Wanted ROM, it's still the same. It was better at start tho and somehow it freezes less in battery saving mode.

Settings keeps stopping

Had anyone here faced such similar problem? On my G7 I have such bug, but I refuse to hard reset . Maybe it'll come back after reset
Maybe there's some solution or maybe some one knows what app is the source of this bug?
These are different phones. Have you posted in the G7 forum?
I had this issue on my g6. Wiped it completely and did a clean install of latest stock ROM. Fixed it and now I have no issues.

Try to clear data and cache of the settings app, also G6 != G7.

I rebooted in safe mode. In this mode settings work just fine. I cleared cache of settings but AFAIR it won't let me clear data neither in safe nor in normal mode.
G6 != G7 , but, well, LG phones have much more in common than differences. Anyway, guy quoted below had the same bug in G6

Yeah, that's what I still refuse to do. But it seems that eventually I'll do it, but not before my G7 would have get Pie. While it's on Oreo I let it keep crashing.
Anyways, it's LG big issue, to have such a HUGE bug in their ROM. Settings in fact is probably one of most used app on a phone. And it's lame to have bugs in such fundamental soft for such a flagship company. I never had such bug in any of my 6 LG models be4
Just a thought... Do you by any chance have a port of gcam 6.1+ installed? On my G6 h870 certain versions of the port caused settings to crash constantly.

Nailed!
Mate, where were you so long? You're soooo helpful. Uninstalled Gcams and problem is now gone. I believed that someone will fix my porblem and you make it.
Well, it must be widespread problem considering how many people keep installing GCams and yet seems as no one knows about it. Strange IMHO
