How to resolve "Unfortunately camera has stopped in Samsung Galaxy A21" - General Questions and Answers

I have experienced that when I start a camera app it just went to stop by displaying a "Unfortunately Camera has stopped" warning. I have restarted my device and again try to open the app and still, frequently it went stopped. How can I resolve this error to start capturing again?

Sometimes it will be caused, when you install the third-party camera app or when an app is not supported by the device hardwires. If it is not working after restarting, just try these steps.
1. Uninstall the other camera app
Sometimes when you are using other camera apps it may block the main camera app on your Android. If non of the camera app installed skip this and move next action.
2. Clear cache and data of the Camera App
By clearing cache data camera will restart with fresh mode and still not running delete the app data and it will resolve your problem.
3. Clear or wipe system cache.
For this purpose go to “Settings”, select “Storage & Memory”, and tap on “Cache data”. Now You can click “OK” to confirm. Otherwise, you can perform stock recovery and the delete system cache.
4.Update your software
Sometimes the pending updates may require proper functioning. So try next time with the installed updates for Samsung Galaxy A21
5.Flash Stock ROM
If you have flashed any custom or ported ROM then make sure to install stoke ROM. If you already have stock ROM download flash ROM by given instructions here.
6.Install Google Camera App.
If all of the above solutions do not work for you try to install the Google Camera app and set it as the primary camera app. Try it after disabling the stock camera app through the settings.
First, you may need to hold on to the app icon and tap on the info option. Then you can press disable the camera app.
Alternatively, you can go to settings, select Application List, and tap camera.
7. Reset your device
If all of the above steps are fail on positive resulting, then finally you can Reset the android device. Before that create a backup of all personal data on your device to ensure the data's existence after resetting. To do that Go to “Setting”, select “Backup & Reset”. Then tap Factory data reset. Now you can Reset the Phone. Read more...

[Q] can't prevent apps stopping

greetings,
I have a new GTablet, started with Tap UI version 1.0-2763. email began stopping, so installed clockworkMod Recovery, did backup, installed update.zip, which turned out to be Tap UI v 1.1-3588. email and more stops, so no help. Also, new problem -- even though System Storage sees \sdcard2, the photo, music and video apps don't see the card. So:
1. how can system be cleaned up to prevent app stopping?
2. how to get the apps to include \sdcard2? (Answer: do a Factory Data Reset)
Thank you

[Hint] Guide to flawless ICS leak

Not sure if all this is required, but after following these steps I have no problems with home or search, calls or SMS, nor Google Play or any FC.
This guide assumes you already made a nandroid backup of your existing ROM and are ready to flash ICS Leak.
1) Flash ICS Leak via Odin .. Do not flash custom recovery yet.
2) Let it boot. When you get to the AT&T screen with Next or Cancel, choose Cancel (even if you use the service AT&T is offering)
3) Uncheck location on Google page and click next
4) Wait for app installation
5) Do a factory reset from within Android
6) Repeat 2-4
7) This time power off and reboot into Odin
8) Flash your favorite version of CWM
9) Reboot into recovery
10) Use CWM wipe data/factory reset
11) Repeat 2-4, except this you can set up both AT&T PC Setup and Google Location if you wish (no point before since we'd be wiping the settings)
12) Enjoy working ICS
Note about the market: The first time you run the Market it will download the new Google Play Market in the background. The next time you run the market, it will install itself. Sometimes this causes FC. If your market crashes after this, go to Applications in the settings and clear Play Market's data. All should be well after this.

Glad I Could Help
btw..for those who are more visually inclined: you can go to YouTube and search for market fix or playstore fix. This fix has been around for years.
Usually doesn't happen with a clean flash...dirty flashing without proper wipes or reset will do that

before flashing a rom, it's a good idea to wipe cache, format system, data, dalvik and then factory reset.
this will give you a fresh start and minimal problems...one may get away with less...but it can be a hassle after you set up and find issues later

Applications start crashing after Oreo update (S7)

Last night i upgraded from nougat to oreo and applications start to crash.
And in some games i can't even log in with facebook / twitter. Everytime time i hit the login with facebook/twitter button, the game crash.
Torrent application not showing any text / pic.
The battery is not draining fast, but faster than nougat's.
Some application don't make to their page. Some do, but few seconds later *crash*.
Octopus' (keymapping app) service is running but the app always crashes when i try to run it.
SmartThings, sometimes bluetooth keyboard and mouse stop working.
I tried factory reset on setting, clearing cache on recovery mode. Nothing works.
I appreciate any help!
Uninstall and reinstall the apps, or clear data and not just cache in app manager.
Personally I always do a clean wipe on new OS versions partially because of this reason, you bring up old data from the previous version and often causes issues.

I did factory reset through setting menu, should i try hard reset?
Ah I thought you meant you reset the app settings. But yes a factory wipe in recovery is going to be more thorough than one through settings.
Other wise you can do a full flash in Odin using the stock firmware files, that method doesn't trip knox / warranty etc
