My phone keeps closing apps, pausing games on its own and putting the keyboard away. Help!

[Android Central Question]

This has been happening for almost a week. I'll go to watch something on YouTube or on Twitch and my phone will go back to the home screen. I'll go to play a game and it will pause my screen in one place. Even as I type these details, my phone keeps putting my keyboard away as if i clicked the back button. I have a Samsung J7 and i dont know why my phone is doing this. Someone please help me!

Never mind everyone! I just found out the reason why this was happening. I had deleted an app from my phone, but apparently it wasnt deleted for some reason. I went to the Play Store after catching the app trying to open an ad and found out it was still installed but wasn't appearing on my apps screen. Thank you for those who at least read my problem!

Welcome to Android Central! Glad you figured it out. Can you tell us what the app was, so that others can avoid it as well?
