HTML5 Videos crashing System UI I was watching videos on m.youtube.com and got this System UI error. Video kept playing, until I pressed ok and everything crashed and 5 seconds later i see the lock screen. I unlock with my fingerprint and anytime I put play it does the same. I tryed other videos and the same thing happens, restart fixed for 5 mintues then I re got the glitch and any other html5 video doesn't work anymore. Also sometimes the home, back and recent apps button and the top bars disappear after this glitch before the screen going black etc. Youtube app works fine though...

P.S. This happened on a Wiko UFEEL Prime running the latest update (6.0.1 [21]) I don't think it can be the hardware because I have 4GB of RAM and a 1.3GhZ octa-core processor.
I found a fix: also if @Geert-Jan Graulus is correct i would let it be a last resort as i keep lots of important stuff on my phone.

My fix: download another browser, like firefox, dolphin, etc. this worked for me. chrome sucks anyway
