I conceded?

I just had this happen where I queued into a ranked match. I'm sitting there waiting for my opponent to flip the coin. All of the sudden the red screen comes down but instead of my opponent conceding it was me? I'm 100% sure that I had not even touched the screen at all during that period. The same thing happened a few days ago but I had hit the settings icon on the top right, so I assumed it was a misclick although it did feel strange at the time. This is annoying because I keep getting the other bug where you can't see your cards during a item search so I haven't even been able to hit greninja yet. I have no idea why this would happen since my internet connection should be plenty fast enough. Has anyone else seen this before?
