For a phone, though, I haven't shopped around. My phone for tsum is an old iphone 6 and I rarely use it to actually play the game.
I think the most important thing to do is to try something inexpensive and then find other means to give it support, rather than going for something expensive with the intent for the stand itself to give you the stability that you need. I support my stand with a depleted jug of laundry detergent that's filled with water. That's heavy enough.
