Android Tablet or Phone Running/Not (Parkstone BH14)

Hi guys. It's a long shot, but I'm trying to get hold of 1 or a couple of older or redundant Android phones or Tablets any size. My boy is studying Mobile App Development and Software Engineering at college and could use a couple of unused Android devices for his home studies to help speed up his work etc. Anything considered running Android 12 or newer. Cracked screen or non working is fine as he can attemp to fix or simply leave the screen cracked if it functions. He can collect and reset it in front of you wiping any personal effects with a factory reset etc. He lives in Parkstone and can collect.Thank you.
