I've had my Samsung A50 for around 3 months and here's my list of problems and despite recent update and factory reset - symptoms persist!
1. The Android System USB Connected/Disconnect notification non stop after charging. This results in heavy battery drain
2. When the above happens so too is my phone screen unable to turn off - press lock button and it locks but keep still keeps the screen on. This occurs way past the time out period.
3. When battery gets low the low battery notification flicks non stop until I put it on charge
Samsung has only advised I take it to a repair centre. My issue is that I bought the phone outright when working in Malaysia but am living in Australia.
I purposely bought this phone so that when my carrier receives the 5G version of the S10 I could start a new contract as I was due for a new phone in April and my 2 year old S8 was rather busted.
I have had so many Samsung devices including pushing my entire family onto them as a b loyal ambassador but I must say this experience has really put me off as other phone companies offer global warranties
Unfortunately issues can arise when an imported phones hardware fails or the software glitches due to how Samsung apply their manufacturing warranty @Dave87
This is one of a few reasons I personally decide not to buy a phone from another country.
However you could try a Samsung Experience Store or Samsung Service Centre to see if they'll help.
That or if any household Contents insurance covers you for replacements etc.
My advice comes from being a UK Samsung Phone Owner.
I have no affiliation with Samsung.

I think is a bug in the last update beacause there are some people with this bug, if this problem still alive with the new update I go to assistance.
I have a problem where I go to type something and the phone will put a random word at the beginning of my sentence. I've finally figured out what it is. If the last word you typed was a misspell, but you closed your keyboard without letting it correct it, then the next time you pull up your keyboard, it will insert the now corrected word into your textbox. Only sometimes though, I havent been able to accurately recreate it.
