I have posted on here before to try and fix my snapchat problem but to no solution and i am here again due to a new reason. I am having a problem on my samsung s20 plus whilst gaming where if i minimize a game to answer a text or something and i go back into that game it starts to lag horrifically even if the game and the messaging is the only apps open. The phone gets extremely warm to the touch whilst running the game as well when it used to not do on other light gaming apps like the ones i play.
My other problem is also snapchat, this app when it is on mobile data doesn't want to notify me if i get a snap, the annoying thing is being a student is that most of the time my phone is on mobile data so if i am missing a training session for rugby in school and my friends snap me i don't recieve the notification. I have put up with this issue since I started using it on mobile data after the first lockdown but it has started to really annoy me now. I have gone through connection settings and mobile data usage and that to try and fix the problem but it hasn't worked.
I also faced the similar snapchat gamming issue in my device I recently bought it from here and know its not performing as well as I expected please guide me about this situation.
