I have the A25. I got the update 2 days ago in South Africa

 you will get it soon. Just pray 

I also got the update

Maybe u need a better phone or you can wait for One UI 7 to be released on the Samsung A25 and see if this update will sort your issue

I have the same phone as you although mines is working perfectly....my phone last 2 days with a full charge.... are you using a Samsung approved charging cable with the charging block? And try to see if ur phone might have a virus...you can scan your...
