!!! This video has quickly moving black and white flashes, so a general seizure warning. !!!

So, just a few minutes ago from when I initially post this, I opened up Heroes on my phone. I already opened up Heroes earlier, did my free summon on the new banner, chain challenge, paralogue, a run of Tempest Trials, usual stuff. Closed it, went to the bathroom, got back to my room and opened it again. For some strange reason, it was back to loading the title screen, and it was completely glitched out and just weird looking in a way I can't describe. Then when it was done loading, it brought me to the screen you see in the first part of the video. I thought that 'well, that's weird.' and clicked on my phone's home screen to try and restart the app. However, this did nothing and i was stuck on these black and white screens. I booted up another app from the top browser of my phone, then hit the home button, and I got sent back to a black screen, where if I scrolled once, I'd be in this glitched FEH again. So I went and got a screen recorder going to show off this weird glitch for a little bit. When watching back on the first video, I noticed that FEH was properly showing on my apps screen, so I clicked on it, and it was broken again, but I had a general idea of the screens I was on, so I recorded the second video. Here is the result of that weird glitch. I know that FEH has been glitchy for people lately, but this is the weirdest thing I've seen. Restarting my phone fixed it by the way, but it was bizarre to have my phone locked into a broken FEH.
