Cannot connect to camera

When I first start the camera app after a reboot I get the message "Cannot connect to camera". If I try to start the app again it works fine every time until the next reboot.
I've tried a factory reset which worked for a few reboots until the message started happening again.
I'm running the latest stock rom and can't figure out what's changing to cause this.
Any ideas?

Had you got that problem on earlier versions of stock ROM?

Sorry, I haven't had the phone long enough to have an older version of the stock rom.

Even I had this error once, I had to reboot the device to get that fixed.
This was the 1st time it happened.
One thing is it happened while shooting a 720p Video.

I don't think it's software problem, probably camera is damaged, or its flex cable. I had the same problem for a moment after disassembling my Play but I forgot to completely connect flex to the connector.
I think the only way to fix your problem is to bring Your Play to authorized service or (if your phone has warranty) send it to SE.

It could be but it just seems odd that its only the first time using the camera after a reboot. Try the app a second time and every other time its fine.
I would have though if it was the flex cable it would be all the time or happen randomly.

Well.

I'm having an issue like that right now. However, I started getting it after I messed with a ton of system files and the framework-res.apk
Did you do the same? I'm working on figuring out what went wrong, it's definitely a software issue for me.

Possible Problem and Solution
Hey guys,
I noticed something really curious after having an extensive conversation about a few r800's and a Moto Cliq XT about camera issues and I've isolated what might be the problem that people are unknowingly creating.

Having the LED/Flash/whateveryouwanttocallit light as a widget toggle in Android 2.3.x seems to use the same line of code as the camera. Or something techy like that. IDK. I was about to fix it after a ton of annoying work. But the easiest way (and fastest really) that I came across was just turning the widget off. Removing it completely. In fact, just get rid of that entire feature in 2.3.x and save it for like, IDK, 3.0+
Really hope this helps that random person out there who needs it.

[Q] Server error occurred. Restart Camera.

The video camera function on my camera is no longer working and I’m not sure why. This phone is less than 5 weeks old and I have already taken videos with it. This upsets me because I have a 4 month old that I love to record especially when it comes to his firsts. The led flash light comes on when I push the video button, the screen switches and freezes. The message saying error prompts and when I close the camera, the led light will remain on until I reopen the camera. Hopefully you can help me figure this out, many thanks!

I install S5 Video App but it does not work properly in my note3. Can I use it in my device?

Which indicates you have been making changes to your phone related to video. Did you remove that or are you still using it.
Without knowing what your phone condition is in, it is very possible that other changes you have made is causing the problem as well...

Most don't need to update their modem and if you installed software that modifies how your phone works, you might try turning them off or uninstalling them to see if they are the cause of your problems.

u could try booting in safe mode and test if theres any app or tweak that is causing it. or u could enter Service / Test / Hidden functions by dialing *#0*# on your phone dialer and u gonna get to the service mode and check camera itself. also theres another one of those USSD codes that brings u to check the phone gadgets hardware /firmware version to see if it same as the camera app... u could also do a full factory restore from recovery screen if nothing else works remember to do a backup first @ titanium backup.. or if you have fair tech skills u could remove the back cover and remove the battery plate and check if tje battery connectors are in place im sure u could find a note 3 tear down video around.. i had the same problem but with the frontal camera and ended up been the camera was defective and replaced it and worked like charm

I know this thread is kinda old, but since it is on the first page on google's query, I'll post a solution here (found on another site).
The solution is to turn off the phone and remove battery for 10-20 seconds. This should resolve the issue.
Some users report that the issue occurs when you charge your phone via PC or laptop USB port. So, to avoid this, prefer original charger.

thanks
thank you for replying even if the post is old! it simply worked while i was about to sell my phone ! good thing i saw your reply first!

Did you ever find a fix?

Screen goes black watching videos.

So, brand new thing I have ran into recently is that no matter what app I use when I turn the phone horizontal the screen goes black and I can't see the video. Any tips to fix this? I am rooted with xposed.

Is there a screen protector or cover possibly causing this issue?
Have you restarted? (Had a similar issue and restart fixed it)
Sincerely,
ASUS_USA

There is at least one other thread about this. Try the search to see if they found a fix. I had something similar, but only with mp4 files, no matter which app I used. Partial or completely black screen, but the sound was fine. It went away for me with the last firmware update.

No case on there for me.

Hi,
I encountered this problem and have a thread on this (http://forum.xda-developers.com/zenfone2/help/video-playback-issue-ze550ml-2-18-40-7-t3139304). Basically, I had to perform a factory reset in order to fix it. Hope it helps.
Cheers.

Hi, did you managed to fix the problem and how if you did?
I have already performed factory reset with the last update 9/7/15 but still have the same problem.

Is it video files or does this also happen with YouTube and other streaming apps?

Just videos, camera videos that I took and others, Youtube works normaly

Asus Splendid was the problem, it was disabled and after enabling and updating it works normally.
If someone have the same problem ...

Video turns black - unfreeze Splendit and autostart

Thanks a lot. That safed me hours of searching! I was just starting to think about the videocodec and all other things I changed..... Would have led me in the wrong direction.....

LG G4 Touch Screen issues. Ghost Touches?

I've been able to replicate this issue on my G4 (815T Australian model) on a daily basis, just on the instagram app though.
I recorded a video of it. Slowmo part shows the issue
https://goo.gl/photos/F823e125PQckCPLp6
The screen seems confused and it just scrolls the other way even if my thumb wasn't touching the screen.
Factory data reset did not fix anything.
Are you able to replicate this LG G4 owners?

I don't use Instagram, so can't help with that app, sorry.
But if you go into Developer Options, and turn on "Show touch data", it might help add some more info to the discussion. It will show a trace on the screen of what the phone's touchscreen interpreted from your last tap/swipe.
It would presumably show a swipe up, and then back down, when you're getting these ghost touches that change the scroll direction. But perhaps it could also help show if swipes are interpreted the same way in other apps. It might help you learn a little more about what the phone is seeing, at least.

Thanks for the video and everything but why a new thread? Plenty of videos on the main thread.
Is another thread really necessary?

Might be, because this only happens with IG. I've got the exact same problem, only with IG and its very annoying.

Apologies, first time I posted it I was thinking it was just Instagram-specific.

You can try to change the touch feedback time from short to medium under settings/accessibility/motor & cogination. This will reduce the touch feedback time. Give it a try, and see if it gets better.

Question, do you have Google keyboard installed? Because I just removed Google keyboard and installed SwiftKey and it looks like the problem is gone....

Nope, I use Swiftkey from the beginning. Only LG stock keyboard is installed.

Mm, I've got LG keyboard freezed with TB and after changing from Google keyboard to SK, the problem is gone

Interesting. Not keen on rooting though. =\
So you reckon it's just a software issue?

Well this problem is only related to the LG G4 and IG for me...I don't have any other touchscreen problems with this phone. So for me I guess this is not hardware related. During the day I just had 2 small "ghost touches", way better than before. Will see how it goes the next few days...
Edit :
after a view days, it looks like it didn't solve this issue. Today I notice the ghost touches were there again in IG

Force GPU rendening under Developer options somewhat helped.
The new v10f on my Australian G4 didn't fix the issue as well.

Any updates on this? I had same issue. N this is a replacement unit after 2.5 weeks of waiting
Just day one and this ghost touch come up.

I also have this problem
Did you solve the problem?

I am facing similar issue.between...i am not using ig.

I've had this issue as well (not just IG) and sent the phone back for servicing. It was sent back to me with a report showing that they'd done a few things but the problem is still there. I'd been thinking I'd send it back in once more and ask them to have another look. I'm getting ghost touches everywhere and quite a bit, it's very annoying.
Someone mentioned there was another, large thread about this issue but I can't seem to find it, can anyone point me to it?

Hi, I posted this in a new thread yesterday as I couldn't find anything. Never thought to search for 'ghost taps' duh.
Every now and then when just doing normal things on the my phone it totally freaks out and all by it self it suddenly starts to tap random parts of the desktop, slides the pages, opens apps, closes apps, goes into calculator and a bunch of buttons are pressed randomly. It's almost like someone has hacked my phone and is trolling me by just tapping randomly on the phone.
Just today when looking at Facebook it closed the app, scrolled down notifications, data was turned off and wifi turned on.
I thought it might have been my screeen protector, bit of moisture in it or something. Took that off and still does it. Took out the battery for a minute and still does it.
It happened a few months ago then nothing for ages and now it's started again this weekend.
Thought it might have been only when connected to data but has now done it when offline.
Any one got a solution? Does a custom rom fix?

Camera not working - ROM |MX ROM|7.8.0

Hey guys,
i have been running Resurrection Remix on my z1c for a long time, it has been quite nice, till the random reboots started and i had massive battery drain. I waited 2 Updates and tried to fix it using some extended methods which i gathered in this forum.
Problem is, i found a good ROM (http://forum.xda-developers.com/son...nt/rom-z5mx-rom7-5-0extended-battery-t3227779) but now i am having huge troubles with my camera. A new install didn't fix the problem, another Camera app didn't solve it either.
The Problem is, the cam doesn't react properly, it has no automatic focus function or even shoots any pictures.
When i try to take a picture, it just freezes and doesn't react anymore. Just locking the screen and closing the app through recent apps will solve the frozen screen. I would have posted this in the same thread as the ROM, but i am not allowed to, since normally i don't post, since all the problems are usually solved by looking through the Threads,
thanks in advance!:good:

When you flashed Z5 Feature|MX ROM|7.8.0|Extended battery did you put a stock Z1C LP FW 23.4.A.1.216 on first.?
If you just put it onto your SD card and flashed it, then it's no wonder you're having problems as Resurrection Remix is a CM based rom. You need to have a stock folder/partition structure in place before you flash 'Z5 Feature|MX ROM|7.8.0|Extended battery'
The other thing you could try is DRM FUNCTION RESTORATION FOR UB DEVICE, maybe the camera is complaining about the lack of TA partition.
