Downloaded on 2 note9s. Phones worked amazingly until 3 days ago. Both phones have graphic flaws, no longer able 2 longpress select. Both phones overheat even on ice packs. Had to remove. We are removing app permanently. After removing & re-downloading 3 phones, they still overheat to the point of not being able to touch them. I have pictures of the shadowed screens. We have no problems with any other apps & see this only using this app. Having a lithium ion battery, I'm not taking any chances.
