Alright, first, I should point out that I'm not a developer or hacker, I've never worked with adb and so on, which means I didn't mess with advanced system settings or anything like that. I'm posting here because I don't know where else to post. Still, I am on the more tech savvy side, so if the solution involves using something like Terminal Emulator, I might be able to do it.

So, I'm trying to install Tekken mobile on my phone (Galaxy S8 Exynos version, Android 7.0, rooted with Magisk and I also have TWRP). When I search the game in the Google Play store app, it doesn't show up. I have to search the play store in the browser and open it in the Play Store from there. If I press install it downloads normally, but then, a few seconds into the installing phase it gives me an error 910. If I try to sideload it, the apk installer fails to install it and says that the package conflicts with an existing package by the same name. But the game isn't already installed on my phone. The whole story is: I actually had the game installed and needed to update it, but the update would fail every time (Google Play Store error 910), so I uninstalled it and tried to reinstall it, error 910 again, I tried to sideload it and the packages are in conflict for some reason, even though the game isn't installed. Can anyone help me fix this?
