How often does this happen? When did it begin happening?
Graphical glitches - all the time.
Random freezes - at least one time at the session.

Is this a once-off issue or has it been a consistent issue? Does it only happen in specific circumstances?
Consistent issue for both.

Steps to make it happen again
Graphical glitches - run game.
Random freezes - fight at least once in story or skirmish mode and keep playing at any way for 5-20 minutes.

Is anyone else experiencing this issue?

I have a strong suspicion that this is due to the device being used, as it is an older model phone with lower level specs that isn’t optimised for the graphics needs of the game
