Black screen when recording videos - LG V20 Questions & Answers

Do you guys experience a black screen for 1-5 seconds when you take videos using the stock camera using auto settings? This happens when the photo size is set to 4:3 and the video resolution is set to 16:9.
Examples (it is worse with SD card):
Internal

Can you guys test this for me?
I need to determine if this happens to all phones or just mines so I can decide to exchange /repair it.
My device is US996 7.0
EDIT: OREO update seem to fixed it. but there is still a slight delay .

Try clearing your cams cache. Other than that...sounds like your phone or software. Also try a different cam app if issue persists.

I tried factory resetting and safe mode. But it still happens. It only happens if I use stock cam using that exact setting using auto mode. Doesn't happen when both is set to 16:9, manual mode or other camera apps like g cam and open camera; there's no black screen but the delay before it record may be still there, but I'm assuming that could be normal.
I'll try updating to oreo to see if it fixes it.
Atm, I requested an RMA for incase I can't fix this in stock.

It don't do that for me...I'm on ls997 classic ROM. Stock or this V30 port I'm running don't do that. Gcam is an odd one...but that's expected.

I updated to oreo and the black screen is gone. There's still like a 1-2 second delay with internal storage (timed it) when I press the record button and when I see the record icon shows up. Should i assume that is normal with this phone?
I probably have to live with that...

Droid X Camera Not Working After Update?

Got the Droid X on 7/15, everything was great, got the system update, now the camera won't work. Black screen only, even though both the Camera and Camcorder apps behave like they're working (with a black screen). Cannot take pictures at all, can take video, although no image is shown and playback of videos is a completely black screen.
I look in the camera and it looks like the shutter is open, although I'm not 100% certain what a closed shutter would look like. I think I can see the lens.
I did a full System Restore, the problem did not go away.
I've tried the camera app from the marketplace, facebook, etc., all treat the camera in the same way: just a black screen.
Trying to take a picture, the focus noise doesn't even sound.
This was working prior to the update, albeit in a laggy manner. Should I return my Droid X, or is there some other software / use fix I have not tried?
Thank you in advance!
No one else is having this issue?
This is the first i personally have heard of this issue.
I would take it back and see if they can exchange it.

After the update I would try to go into the camera but it would say that it couldn't open it. A couple hours later it worked no problem. I recommend a factory reset to se if that helps and then try to exchange.
Edit: sort I didn't se that you already tried to reset it. Yeah it is time to take it back.

I've tried a soft and hard reset and no luck. But a quick search on the Motorola forums brings me to conclude that this could be a major problem that if it doesn't happen to you now, it might just happen later.

I have two droid X phones. My Camera quit the first time I tried to use it after the update. My daughters died 2 days after she updated. Verizon fix is to send me a refurbished phone. My fix is to get rid of motorola and verizon as soon as possible. Any help would be appreciated

Mine did same thing... i pulled the battery while phone was on per the tech on the phone and it has worked fine since.
I have noticed this on rooted droid x's. Factory wipe didn't really resolve any of the camera issues. Re-loading with SBF resolved the issue sometimes, while other times, a simple cache wipe resolves the issue.
I dont know if this will work, but its just a suggestion that fixed my camera. My camera/camcorder app wouldn't open, so then I went into the gallery and deleted a corrupted image (It was all strange looking, a black square with lines on it, and also wouldn't open in any programs). Once I removed this image from my SD card the camera worked. Worth a try I guess...
Also try using another app to open the camera, like Vignette, in order to see if it is a hardware issue or a blur camera app issue.

Camera testing

While checking the camera I noticed a few symptoms:
[-](Taking photos at night/low light): with/without flash sometimes the photo saved with 1pixel white line (sometimes 2 pixels), the line is random and change to each photo - at the top starting left / left starting buttom (depend on which way you take the picture), here is a sample of picture with this line (circled) at the buttom.
I've found it happens sometimes while taking picture in low light/dark/night, have no idea why is that and what the reason of this.
[-]Another thing while taking picture at low light/dark background with flash: dosn't matter how you focus (auto focus/manual-touching the screen/long press on the button) seems like you should take a few photos of the same image to get a 'satisfactory' picture - I took few pictures on the same place and got some too 'flashy' photo, some too darky (seems like the flash was too fast) and some was what I've expected (OK), at the dark pictures seems the +2 exposure didn't help (didn't notice any difference between 0 to +2, but there is a difference between -2 to 0) -> seems you getting different photos on same shot image and must take few shots to get what you expect to get.
[-]The picture that seems to save after taking a shot sometimes looks different then what its realy saved, for example you taking a picture with flash - its looks like its saving a too lighty/flashy-full flash picture but when you open the gallery you see the picture is fine.
[-]HDR mode: sometimes when its getting focus (manualy or automatically) its not possible to change the focus and any attemp to manual focus (while touching on places on the screen) is do nothing and seems its stuck on the last focus.
[-]Video: sometimes seems its stuck on focus - after focusing on macro/closer image and taking time (if so) to release the focus to infinity, if it dosn't release the only way to fix it is to renter the camera app and record video again.
[-]At day light / regular conditions - great and sharp photos but seems its more grainy then other cameras, especially photos with sky (the sky).
Overall its a great camera, all the above are not something that should disturb someone, I didn't forgot its 'just' a smartphone camera, you can always get better results using 'SnapSeed' app
Does anyone else notice these (or some of these) symptoms and have any knowledge how to get it better or solutions or maybe insights about these symptoms? (the using of camera) would like to get some information...
Anyway - do you recommand other Camera applications? I tried Focal - seems its still have a lil bugs, FV-5 (on my S2) ...
Thanks!
Today I've notice a bug [seems like a real one this time]:
When took a photos: low light + flash (macro focus if its matter), while I took few pictures one after another the camera app got stuck and reboot the device.
I've tried it without flash and didn't got reboot, then its happens again while I've checked at the same condition (low light and flash on).
Also notice that none of these photos (that freeze the app and reboot my device) are saved correctly seems like its 'break' pictures that didn't saved well...
Anyway after I manualy reboot the device and tried it again it wasn't crash/freeze/reboot device.
Just mention that I'm using the stock camera app at stock rom 4.2.2 without root or anything...also my device was on for few days (without any reboot).
Does anyone have any idea about this bug or other symptoms that I had mention at the 1st post?

I have the same problem as you are describing. I have reproduce it on stock 4.3, cm 10.1.3 and cm 10.2.
I just reproduced it after I took like 100 photos. The Phone just rebooted after a short hang.
Maybe this is a hardware fault on some devices. When did you bought your Phone? Mine is the white one just a week old. Rev 11. If that says something.

Seems like the flash heat the cpu or something like that...happened again today (without purpose) after few focus with flash few photos with flas..at regular photo without flash (straight after) it got stuck and reboot the device.
Then I tried to get it again but now with Camera360 app, lots of focus flash,photos with flash,without....seems works fine.
Maybe a stock app problem, guess anyway its the flash (another guy got reboot after using flashlight app).
There is any app that I could determine the CPU temperature even after reboot/turn off (like GSAM graph or the built in Battery graph that show all day and not only when you turn on /reboot device and start a new one every time)?
Btw - the device is only month old (from play uk), my serial# start with 304k, whats yours?
Yesterday night I had this again, only 2 photos with flash, take a look at the gallery and got freeze then reboot.
The device was cold [also wifi was off this time, I didnt tought its something to do with it anyway just mention] so nothing about hot cpu...
It might be something with the stock app and/or stock gallery app [maybe the swipping thing from camera to gallery and vice versa], as I tried again camera360 with lots of flash, focus flash and lots of photos and seems it was fine.
Very weird.
What camera app do you guys recommands?
I think it's an issue with the AOSP camera app. My rev. 10 211k Nexus 4 does this sometimes when taking a picture with flash on. It hasn't done it with a flashlight app ever though. I haven't encountered this issue with Focal, but I don't like Focal much.

Yeah, seems like its something with the stock camera app... I really like the stock one, Focal is almost the same with some more options but it isn't stable yet.
I found camera360 doing great job but I like the stock-clean design more...
Anyway I hope the new KitKat version will fix it.
BTW - any reason/idea about the first symptom that i've mentioned in the first post? [the white 1pixel line], and about the stuck focus on HDR mode?

I've got a rev 11 White too, I've got a strange Issue, if I take a photo with the stock rom with flash on with and without touch to focus everything seems to be right; If I take a photo with a CM based ROM without touch to focus I obtain an almost black picture, could it be an hardware issue?
And one kiddish doubt , why we can't take 16:9 pics ? Any idea ? Or it is possible and am I missing something ?

I've notice it too, also with stock, I mentioned it as well - seems like we need to take few photos of the same thing to get and chooce the better result, I've found it sometimes the flash is too fast and its taking the photo just before the led turn off or before its turn on fully... something like that. but its on flash photos most of the time.
Try taking 10 shots of the same thing, you could notice a difference between some of the pictures. (BTW I think its happens with and without touch focus; it dosn't matter)

I guess some other camera app (3rd party) would have this option... anyway I'm still waiting for any recommand about a good camera application...

Camera not found

Sometimes when I'm shooting photos, camera freezes for few seconds and I can't take any photo or video, sometimes the UI disappears. And if I check in the gallery app I don't have the last ones. I have to reboot or to wait few minutes to get the photos back in the gallery. It happens using internal or SD card memory, and wiping cache or data doesn't fix the problem. I noticed that Aida64 can't find the camera in devices tab. Anyone with same problem? Or any solution?
Hate to say it, but that's a hardware issue. I would try factory reset just to see if that helps, but I suspect it's hardware, and you should return it under warranty.

You can try check "original camera": Press *#0*#, Mega cam.
If no problems, you can hardreset the phone. (I think that's a hardware issue).

Tried and no problems. I flashed few days ago the official firmware because i had this problems previously, but nothing changed. Is that the same as hardreset?
I noticed that sometimes phone freezes while deleting photos from gallery, no matter if they are in SD or internal storage.
Something wrong your phone, and I believe it is hardware defective. You shall go find the shop you buy or send for service.

To fix software, Flashing is final method. So it is hardware issue. U should return it under warranty. Ok

flickering observed in panorama mode

hi guys, just got my U Ultra last week. just tried the panorama feature today and observed that were flickering lines in panorama mode and it can see it flickering throughout the whole panorama I screen. the flickers then appear as lines inside the actual picture. this flickering wasn't observed in other camera modes. Did anyone encounter the same issue or I have gotten a lemon

Hey there,
is this in normal panorama? or selfie panorama? I havent noticed it on either, but there was an update to the HTC camera app (not a system update), where there was an improvement made to selfie panorama (I dont know exactly what it is), perhaps try installing the new app and see ifg it works for u?

Hi, it's normal panorama, I saw the issue after the app update. Didn't actually use panorama before so Wanstead sure whether it was causes by the update. Didn't see this issue in the selfish panorama or video modes though

I had to return my first U Ultra (Blue), as it had various issues, screen freezes, flickering on the home screen.. and when taking photos outside on a sunny day, it was blowing the "sunlit" areas out with a white misty ghosting effect (probably faulty focus / light sensor unit), however, after changing to the Black version.. its all been fine now.
Might seem silly.. but if youve done the update... open Camera, goto Settings and "Reset to Defaults" then goto Settings > apps > Camera and Force Stop, then Clear Cache and Clear Data, then restart your phone.. reset your camera back up .. and try again..
Lets know how you get on

S8 weird camera problem

Hi guys, I have been dealing with s8 camera problem for months now and decided to ask before I smash my phone into the wall.
Problem looks simple, I start recording and it randomly stops. Its followed by quick flash(the one that you see when switching the camera on) and looks like camera is restarting. It happens after 2,5, 10 seconds or sometimes doesn't happen at all. I recorded a video of my baby and after 20s I found out that recording stopped and I didn't get anything. I tried to use a camera in safe mode, seems to be working fine there.
Does it mean that some apps interfere with camera app? Also tried cleaning the cache which didn't help. Is there a way to find what apps are causing the issue? Is factory reset best option in my case? I would add that I can see those weird flashes even when I'm not recording and camera is simply switched on.
I would appreciate any help guys. Thank you.
Do you try some other camera apk ?

Yes, they worked fine and didn't have any issues. I would like to use an original app tho because I find it much quicker and less complicated. Wonder if it's maybe related to Samsung cloud sync. I'm just too scared to factory reset lol
So you are saying that U never tried to solve the problem by doing a factory reset? That should be second thing on your list, after restarting. xD
