Regarding MTG Arena for Android.
Memory is NOT my issue because my tablet has plenty. But during download and installation of the update released August 19th, 2025 my tablet froze up several times during the download. Once I got to about 512 Meg remaining to be downloaded, it finished without further issues.
However after the initial match during game play, the game now kicks itself out of the active mode during the moment that a new opponent is selected. Tapping the game's window to reopen brings up a black screen with frozen game. Exiting the game entirely and reloading doesn't bring you back into the match. You have to stay out of the game for several minutes until that nebulous opponent is declared the victor by your absence before you can successfully log back into the game and resume it.
So far, it hasn't crashed yet on the initial match played. Only the second or third one in.
