Wall Display Device Suggestion?

I have some old iPad 4s on the wall now and they have issues with displaying custom icons for some reason. I guess there is a bug in custom_ui and it doesn’t work well with the iOS 10 device - the iPad 4.

What is a replacement device that would be fairly inexpensive that will display everything on the HA dashboards without any problems? Was looking at the Amazon Fire HD 10 for $150, but not sure if that’s a good choice or not.

Thanks!
