I also need help, I have the same problem, accept it happened right after I won a battle, here's everything on what happened; I searched up on how to mega evolve my Pokemon, Google said you had to make the Pokemon you want to mega evolve hold a mega stone and then tap use during battle. but when I tried to make a Pokemon hold a mega stone, it didn't work, so I thought, "okay, might as well register the mega stone and tap select during battle, I guess." Didn't work, so after I demolished the opponent, I started to repeatedly tap the select button while it was still transitioning me out of the battle, and it opened up me inventory, I closed it out... And got this screen.And I honestly don't know what to do, I tried saving it, re-loading, closing it out, re-open the app, and then repeat the process a million times!!! Also some important information, I'm not using a switch, I got this game on my Amazon Fire Tablet using Aptoide, a remake, but still emerald.Any ideas? Also, no one is allowed to say, "Oh, just restart the game." BECAUSE I CAUGHT THE LEGENDARY POKEMON LATIAS, SO I WILL DO ANYTHING TO SAVE MY POKEMON, I WILL RESET MY PROGRESS, JUST AS LONG AS THERE IS A WAY TO SAVE MY POKEMON...
