Backup image

Android OS is totally different than a PC OS.... As explained above, that is your only option.
IF you don't want to root your device, you'll need to backup everything separately. Google photos will automatically back up your photos and videos...
Google contacts will automatically back up your contacts.
The Play store will automatically back up your apps.
And you'll need to find a sms backup app that can save your messages.
Keep in mind you'll lose your app data also.

Help Note 4 issues

Yeh, think it's worth trying a backup and factory reset, given what you've said. But it's still restarting etc, that could be inductive of a hardware problem, or given the age perhaps it's the battery is kaput?
Thanks for this, I have run a few 'repair and diagnostic' apps and the battery seems OK. It was new a couple of years ago. I will do a back up with Smart switch I guess and see what happens

Help "Android/Data" empty. Why?

Game apps and such. I remember i was able to install mobile games and see their files in "Android/Data". I want to know how to access them.

Then you need a rooted device, and/or an app that will allow you to see and then manipulate those files.

MTK is a file manager/explorer than can do this.

I have had some limited success even on non-rooted devices with MTK.

You must first extract the apk file of the app, and then copy it.

Then you can use the copy as your disposable testframe.

Keep in mind that it is not lawful to modify many apps.

Samsung A50 Data Recovery

How do you use a fingerprint without knowing your security code? Every phone with a fingerprint reader I've used will periodically ask for the code to verify that it's really you (since fingerprint is regarded as weaker security than a PIN or password)?

I assume from the question that you've not synched any of your data? For example if you stored your contacts as "Google" contacts they will automatically be backed-up to your GMail account unless you have changed settings to stop this. I think Samsung used to do the same with Samsung accounts, but as I never created a Samsung account even for my Samsung device I'm not certain. I would however suggest checking your GMail contacts via a browser to see whether they have been backed up already (and maybe also check things like Google photos as well).

Otherwise, unless you set the phone up so that it would allow USB debugging without unlocking the screen (and you'd probably know if you had) you are probably stuck unless you can remember your code.

Hii

My phone is making a vibrant sound when some one is calling me but I can't hear it what's the problem in my phone
so you can't hear the vibration? or you can hear the phone ringing? or you can't hear the person who is calling you? is your sound turned down as suggested by @Dannydet? do you have the phone set to ring or just vibrate? can you give us more details?

Mine bitcoin on your Android device

I guess no one could have expected it, and it's still a long way from home! Where are all the disbelievers that were advocating against Crypto and Bitcoin with passion? I was dead sure that 30k would be reached sooner or later and now it's about to hit 100k. Give it some time, and it will go there as well at a point! I have little BTC but I'm still planning to add more to my portfolio with the new miner I bought from evominers.com and now I think I have a great chance of becoming even richer in the near future!

S21 5g hands-on reviews

Interesting to see all of these. They've shown me that it would not really be worth going to the s21 from the s20, much less the plus. I love my s20 plus, and I LOVE the price they got the s21's down to, and while it is not technically a downgrade, there isn't really anything to convince me it would have been worth trading in one for the other.
But, going to the s21 ultra from the s20 plus? YAS :D
