Camera crashed. Lost everything.

I'm so mad right now.
My camera app crashed even after several reboots forcing a Hard reset.
I lost all my data and the camera app still crashes.
I can't describe how mad I am.
I press the camera button and it shows for a sec. It then immediately returns to the home screen.
I'm gonna contact Microsoft first thing in the morning.
I might lose a job because of this.
The hard reset didn't fix anything. It still crashes .
Can someone link me the he fastest way to get to Microsoft to help me fix this stuff.
I'm seriously going insane. All me stuff is gone and since its impossible to take a backup I'll never get it back.
Die, Microsoft. Die.
You just made me lose heaps of things because of a camera flaw.

Thanks for letting us know:
1. What you were doing when it crashed.
2. What type of phone you have.
3. Whether or not you're using a 3rd party MicroSD card in the slot.
4. What actually happens when it crashes (phone freezes, app just closes, middle finger graphic comes up on the screen, what does it do?)
5. Were you on WiFI, EDGE, 3G, GPRS?
6. Are you sure the device isn't defective (And/or prematurely failing on you? In this case, the OS has nothing to do with it - can happen on any phone running any Smartphone OS)
7. Other trivial information that can cause us to come to better conclusions.
Instead, you plummel us with bad grammar, vulgarities, and a rant that will certainly accomplish nothing due to #s 1-5.
BTW, you should back up all important information on any device. Laptop, Tablet PC, Desktop PC, Smartphone, Thumb Drive, etc. It's not Microsoft's fault if you lose you fault due to data loss. Important information should be backed up and IIRC Windows Phone 7 is capable of keeping the Camera Roll Sync'd up with SkyDrive.
I give you 3/10, though.
Ciao!

You might try Windows Phone Support on twitter. They usually reply pretty fast during business hours.

A side note, if you've got a job that depends on your ability to take pictures, you might not want to depend on a phone's camera and use a dedicated camera.

@Side Note: Still shouldn't matter. Anyone that takes (EDIT) photos for business use with their phone camera should have the SkyDrive Camera Roll Backup/Sync enabled and you can set your Photo Gallery to Private.
The OP's situation is completely avoidable.

This is either a very bad troll or you're a complete moron. I can't decide.

damn my camera app crashed too yesterday after i was changing some settings.
i turned off light and changed the measurement adjustment.
it crashed when i tried to focus the object. black screen, crash.
so happy a restart fixxed it, i better dont mess with the settings for some time...

Yeah, besides, Microsoft did not MAKE you do a hard reset of your device.
If you read the manual and understood what you were doing before you did it you would have known that a Hard Reset puts the phone back to its initial state.
You must have also disabled image syncing onto Zune which would have backed up your photos everytime you plugged it in or Wifi synched it. Could have also auto-uploaded the pics to Skydrive and had a lower resolution copy on there.
Can't blame Microsoft for this. Yes, the camera should not be broken, but most times a soft reset will fix any software issues.

Bah, sorry.
I was kinda drunk when I posted this.
I was at a party.
But to answer the questions:
1. What you were doing when it crashed.
Nothing. I tried to take a picture by holding the camera button whilit was still locked.
2. What type of phone you have.
HTC HD7
3. Whether or not you're using a 3rd party MicroSD card in the slot.
No, I did not modify my phone
4. What actually happens when it crashes (phone freezes, app just closes, middle finger graphic comes up on the screen, what does it do?)
It shows the zoom bar on the right, then immediately closes and shows the start screen.
5. Were you on WiFI, EDGE, 3G, GPRS?
Edge
6. Are you sure the device isn't defective (And/or prematurely failing on you? In this case, the OS has nothing to do with it - can happen on any phone running any Smartphone OS)
Nope, there's nothing wrong with it other than that.
7. Other trivial information that can cause us to come to better conclusions.
Not really, I never did anything special to it.
All I did that evening was texting, calling and updating my status on Facebook because the power blacked out, three times.

Ok, so after the third hard reset the camera works again.
But now all the pictures I take are rotated 90 degrees
I think there's definately something wrong with the camera app.

Sounds more like a HW problem to me (wouldn't be the first for a HD7) as it doesn't happen to everyone else.

Yeah, sounds like a bad HD7 to me too. My first HD7 was an awesome phone, if by awesome, the standard you use is how often it simulated Windows XP by crashing on me.
Returned it and got a new one and it's been smooth sailing so far.
Send that POS back and replace, blame HTC not MS and don't do your business while drunk otherwise it won't be the phone's fault you lost your job.

i don't know which is worse, being unable to identify the cause or blaming something else other than the cause

Honestly, I'm actually surprised somebody hasn't posted Die, Badboy70. Die. because of this post, XDA is maturing. Anyway, your Zune auto syncs your photos by default, I'm assuming if you do this for a living, you'd know not to turn this off. So, I'm going to go out on a limb here and say that you're FOS for saying you're losing a job because of this. I'm betting more on you being a 14 year old who's phone is malfunctioning due to a hardware problem and had to come rant about it instead of asking for help.

Your excuse of being drunk just validates the first part of my phone. You won't know your device is defective without a professional looking at the camera hardware. Just becase nothing else is messing up doesn't mean the camera isn't defective. Considering it worked, and then didn't, especially on factory settings leads me to believe this is hardware related, if it even exists at all. I would try to replace the device.

It's more likely to be a defective HD7 ...

Doesn't a hard reset delete all the data off your phone? So instead syncing it to your PC and extracting the photos you decided to delete. It may be MS fault that your Camera app crashed, but its your fault the data is missing. Why didn't you back your photos up on your computer or even to skydrive? Couldn't had been to important if your didn't.

Note 4 Suddenly Having a Multitude of problems. Hardware Issue?

Hello, I have had my Note 4 for quite some time now and have not had any issues with it up until the last month or so.
At first it started out as just a hiccup every now and then, an example would be when I play music via bluetooth to my Jeep CD Player, I would sometimes have to turn bluetooth off then back on to get it to connect or reconnect.
Now things are getting out of hand. Here is a list of problems I have on a daily/hourly basis and seemingly at random times. I cannot reproduce any of these problems (except the NFC problem) on demand.
I have noticed that rebooting the phone will clear up these issues (except NFC) for a short time, SOMETIMES. Other times a reboot does nothing to help the situation.
Keyboard Lag
Sometimes when I press the keys the phone vibrates indicating a key press and magnifies the key that is being pressed, but fails to enter anything in the text box/input field. For the record I am using Swiftkey. I have noticed that this happens most often when I open an app via "popup notification." For example, if I were to receive an IM or SMS I would tap on the notification that pops up, which then switches to/opens the corresponding app. It is then I will more often than not have this issue. To remedy this I have to close and re-open the app, sometimes several times causing the keyboard to open and close, several times... Sometimes when I TAP a key, the phone will behave as though I have held the key down or performed a "long press." This issue is not exclusive to the keyboard, it often happens anywhere on the screen and with any app, usually indicating that I have been "long pressing" for about 1-2sec at a time.
NFC Does Not Work
One day while I was at work I attempted to add the office printer via NFC. To my surprise I was unable to turn on NFC via the "quick settings" drawer. In the quick settings panel the NFC icon would light up, as if it were turning on, and then just turn right back off again, this happens consistently. I went into setting to enable NFC that way and I am stuck with a slider that is actually in the "on" position but greyed out, I am unable to interact with it.
Bluetooth Connectivity
I have a JVC CD player in my Jeep, I often use YouTube or Google Play Music when I drive. Usually I do not have any problems connecting to the CD player at first, but after about 30-60sec of playback the audio goes blank. The app says that it is still playing however no audio can be heard. Then it will suddenly come back on after about 5-10sec, and here is where it gets strange. After the audio comes back on after this "hiccup" the playback is fast, as in it is playing at 2X's it's normal speed, makes the vocals sound like chipmunks. This will continue indefinitely until I turn on the screen, unlock the phone, then shut the screen off. Then the audio goes on playing fine. This happens with both YouTube and Play Music, while using YouTube the video gets sped up as well. I also experience issues with connectivity where sometimes at random the phone will just disconnect from the CD player, and refuse to reconnect until I have rebooted the phone, or if it does reconnect I get no audio until the phone is rebooted. I notice that this ONLY happens when connected via bluetooth. If I turn bluetooth off while this is happening music will play over the phone's speaker perfectly normal. My CD player has a hands free feature, and I do not seem to have any issues with phone calls, it's only with music playback do I have problems.
Originally I thought it was my CD player acting up, however in light of the other problems, and the fact that I tested it with my tablet and two of my friend's phones without issue, I don't think the CD player is the problem.
Sluggish/Glitchy UI
Sometimes when the phone really freaks out, the UI behaves very strangely. Sometimes notification Icons will hover above the running app, other times the whole screen will lock in place for a few seconds. Sometimes if the screen is locked up, I will shut it off, then turn it on, shut it off, turn it on. However as I press the power button to turn the screen on and off, nothing is happening, the screen just stays black while the "back" and "recent apps" buttons light up at the bottom. Then when the screen does finally come back in it will flash on and off quickly in accordance with how many times I pressed the power button. While all this is happening, if I hold the power button to turn the phone off, the power/reboot menu will appear without incident. Sometimes when I am swiping to unlock the phone, it does not register the full swipe. Basically it acts/appears as though I lightly touched the screen and moved my finger a half inch even though I have drug my finger all the way across the screen. To remedy that issue I have to SLOWLY drag my finger across the screen and then it unlocks without incident. I have also noticed that when I go to "swipe away" a notification, especially one that has "information" in it, it will swipe off the information but leave the notification there and display the app name the notification was from. An example would be, if I just installed an app (for example YouTube) from the Play Store, the notification will say "YouTube has been successfully installed." When I swipe either left or right to remove that notification, a "white ghost box" or "overlaying top layer" with the "successfully installed" text in it will slide away. However it leaves behind a green box/notification that says "Google Play Store" and that remains until I shut the screen off and turn it back on.
NFC Will Not Turn On
I simply cannot get NFC to turn on, the slider is in the ON position but is greyed out as I mentioned earlier. I would post a picture but I guess there is a 10post rule before I can do that. I have given up on NFC, mostly because I rarely use it, so it's really not that big of a deal.
Initializing the Camera
I use an app called "Telegram" instead of SMS messaging, thus I use Telegram to share pictures with friends. Sometimes, again I am not able to reproduce this problem on demand, the problem comes and goes seemingly at random. The camera will take more than 30-60sec to initialize, while I am waiting for it I am stuck with a black screen. If the camera doesn't initialize, shutting the screen on then off will take me back to the telegram app. I never get an error message or anything. Other times when I try to use the camera it pops on instantly and works flawlessly. Originally I thought this was a problem specific to telegram, however in the name of science I tested it with the default camera app and get the same results.
USB File Transfers
I'm not really sure this is specific to my phone, but whenever I transfer files from my PC to the phone or from the phone to PC, it is PAINFULLY slow. It's even painfully slow when the PC just displays what is in the folder. However I can't say for sure this is related because I never attempted to transfer files until I started having these issues, at which point I thought it would be a good idea to start backing things up.
Gets Stuck in 3G Mode
This happens rarely, not even sure that it's related but I felt that it was worth mention.
What have I done to try to remedy this problem you ask?
So far I have performed a non-root ADB nandroid backup, just in case factory resetting the phone didn't work.
I have factory reset the phone 2 times, I see no improvements.
I have cleared out my SD card/removed SD card
I removed and/or shut off bloatware apps (Yes I tested the phone without removing/disabling bloatware, still having the same issues)
Wiped cache via Recovery
I am not sure what else I can really do to fix the phone, I am starting to think that this is a hardware issue. I should mention that there was no significant event that I feel would cause these malfunctions. System update installed and worked perfectly up until this last month, I have not dropped the phone from significant height, the phone has an otterbox anyway. I have not gotten the phone wet, it has not been left outside, this phone has not seen any abuse what-so-ever. I just started having these problems out of the blue and they seem to be getting progressively more frequent and longer lasting. If I don't get any ideas from here I am going to try to get Verizon to replace the phone via insurance, however I don't have high hopes for that because I have grandfathered unlimited data and this is not the "original" phone that I had when I added the insurance option, so I am not sure it's covered.
Does anyone have any ideas on what could be causing this or anything I can do to correct it or try to troubleshoot it?
Any help is greatly appreciated!
Phone Information is as follows:
Samsung Galaxy Note4

I realize that this is a long post but whenever I ask for help I like to be detailed. If I left out any information that might be helpful please let me know.

Unfortunately, it looks very much like components on your logic board are going bad. Sometimes a few specific things will go bad that don't actually make the phone unusable, but make it act similar to what you are explaining. It wouldn't be worth the money you'd have to pay someone to track down the bad components and replace them. If you really like the note 4, I would just make a full backup with kies while you can, buy a new phone and restore your backup.

All of Kies backups do NOT restore to a new phone! Only contacts, messages and call logs will restore on a new phone. Use Samsung Smart Switch or Helium. Good luck

No response bugs

Some background info.
I bought my pixel XL from the Google store and I believe it came with the 63L build out of the box. I have since made it a point to completely wipe and fastboot flash the latest image Everytime an update is release, right now I am on the 26U build. The only thing I have done to my phone (and these bugs happen before and after) is bootloader unlock and root.
The bugs.
Every once in a while, my volume controls will quit working. I notice it happen more if I cast to my Chromecast and play a song or video (seperate) on my device. I'll hit the volume button and literally nothing will happen. To fix this I usually have to turn the display off, wait a few seconds, wake it back up, then the controls work fine again. I do not believe it is a hardware issue because i can fix it Everytime it happens.
The second bug, probably the most annoying, is that my nav bar will become completely unresponsive occasionally while in landscape orientation. Say I'm watching a video on YouTube in full screen, if I swipe to pull out my nav bar and hit the home/recent/back button, nothing will happen. I will see the animation however no vibration (feedback) or a action occurs.
This happens in games, YouTube, web browsers, doesn't matter as long as my phone is in landscape mode. Also note that when this happens, my device refuses to rotate back to portrait. This leaves my only solution (same as the volume bug) to turn off the display, wait a few seconds, and then I back on. Sometimes, however, this don't even work, and I'll have to jump straight to settings from my lockscreen to force the phone to portrait where the functionality of the nav bar returns.
I've contacted google, they run me through the typical steps "delete cache, have you tried a reset, update to the latest software", but nothing fixes it. They have told me repetitively it's not a common problem and it's not a problem that's worth rma'ing over.
I've been discovering my pixel has many small issues that no one else has. Such as the horrible transfer speed explain in my earlier thread, these bugs above, refusing to charge when the device is off, etc.
Has anyone had similar problems?

@noidea24,
I've had none of those issues. In fact, my Pixel XL has been flawless.

Not good. I guess I'm going to try and force a RMA.

Sorry to nit, but when I read the statement above I can't help but wonder if you actually did a factory reset. Reason I say that is you stated "have you tried a reset" and you didn't explicitly state that you did.
I kind of doubt the responsiveness stuff you're referring to is hardware related, it's probably software.
Whether or not a rogue app is affecting your device or a root app is impossible to determine without doing a factory reset and carefully adding one app/change at a time until the problem comes back. It's a PITA but that's what I'd do first to rule out hardware, and I'd simply run email and messaging apps unrooted for at least 24 hours to rule out hardware issues before I start loading up my favorite apps.

A factory reset is far from a pain in the ass, and yes, i have done it many times. the only things that makes it suck is when i have to transfer files back to my device because (as mentioned) i have terrible transfer speed from pc to device.
i have literally done everything i can to make this devices worth the price, and things are only getting worse. Since the post (later that night) i factory flashed once again, and re locked the bootloader. No root, No extra apps, hell, the only apps i had on my phone to begin with were facebook messenger, and that pixel car racer, i dont use anything else. ive had an even worse bug come in where my phone completely freezes when opening google camera and swiping to the video section. ill have to hold power until it force resets.
ive been with xda since my Motorola droid, Ive built roms for the community for my lg g2 and my nexus 6. hell, i even built kernels for my 5x (not public), so im a little past your average user complaining about some things that dont work due to user error. these are legitimate device flaws and malfunctions, and i was simply asking if anyone else has experienced them. and since it seems no one has, i have deemed my device faulty. now i have to come up with $600 for a service hold to get it replaced.
My experience with Googles first official flag ship has been pathetic, and im hoping that this replacement device i get (eventually) will persuade me not to go back to my 6p.

Well if that's the case then yeah I hope a replacement device will solve your issues. Sounds like it will.
Didn't mean to rile you up, just looking for clarity.
Good luck!

LG K10 settings issue running android 6.0.1

My LG K10 every once in a while will start making intermittent sounds similar to the old "Pong" game. There are no text messages or window or alerts that pop up when this happens, it seems to happen randomly and sometimes the sounds come through in rapid fire succession if I am driving around town. It tends to wear down my battery faster whenever this occurs. I check to see if any functions are active by hitting the square at the lower right corner of the screen and nothing shows as running.
Also when this happens a volume setting bar shows up as a pop up at the top of the screen, if I try to mute it, it does not allow me to. If I move the slider bar all the way to the left to kill the volume, the next pong sound moves the bar over to full volume. When this occurs I have zero control of the audio output volume of my phone.
This is extremely annoying and I am about to smash this phone into a thousand pieces. Questions, is this the result of a virus? Or is this the result of someone else taking control of my phone? Is this some kind of "feature" of which I am supposed to be thankful? Is there any way on this planet to put an end to this hyper annoying BS?
This is my first Android phone, I was an iPhone user previously. I am seriously considering getting rid of this and going back to iPhone. Please help.

Yes tried admin, there are no admins other than Android Device Manager.
I have not added any apps since I bought the phone.

To me it sounds like half functional malware. Did you bought new phone from shop, or used one from someone else? However the best way of solving would be to flash stock firmware, you have tutorial for that on this forum.

I bought the phone from the T-Mobile store as a brand new phone and have not installed any apps. I assume that flashing the FW means I'll have to backup all my contacts, correct?
And thank you all for your answers I appreciate it.

Well you can backup them just in case. But they should be synced with Google so they will appear on phone once you login with Gmail account.

Assuming I have a gmail account which I don't. So backup it is. Can I do it by attaching it to one of my computers via USB, backup that is. Thanks.

Yes you can, but first you will have to make backup file on phone, or you can backup contact with some LG PC software. Also you can backup to Dropbox/mega/drive via share option from contacts. Let me know did you solved problem via flashing stock firmware.

Glitch in S20 layout?

Hi everyone, I hope someone here can help me.
I'm experiencing a bug on my phone that's bothering in several situations.
Apps in landscape mode switch to portrait and come back to landscape (or not):
http://imgur.com/gallery/vfgSCPn
Voice notes in WhatsApp get interrupted:
http://imgur.com/gallery/yXIlFbI
(you'll see that the navigation bar briefly goes white)
I've factory-wiped my phone, gradually reinstalled the apps and double-checked that there are no weird or potentially dangerous apps.
The tricky part here is that I can't find a pattern, as it randomly happens (for instance, my keyboard went down when writing this actual post).
Has anyone else experienced this problem with their phone? Any idea on what I can do? It's really hurting my experience with Samsung.
Thanks!

You might try another Android version.

Clear system cache on the boot menu.
You can try a hard reboot as well.
Test the sensor(s) that controls that (it could be an intermittent failure, the worst kind to diagnose).
Does manually locking it to landscape mode stop it?
If it's a brand new phone, get it replaced as this is not a normally seen glitch.
Reloads generally don't cure settings or hardware issues and useless it's an old load or has a worm, trojan, etc are generally a waste of time.
As invariably the original issue just gets triggered again... eventually.
