Yes, and the result was just the error popping up again before sending me to the home screen.
I might just replace the phone at this point. It's not worth taking it to be repaired.
I followed the steps on that site and it put me in safe mode.
Also that phone doesn't look like mine but I turned it off, help power+volume down until the logo popped up, then held them again.
Re: System UI stopped responding LG S5
No. it opened to my home screen with less apps and said "safe mode" at the bottom of the screen. I couldn't tap anything.
Re: System UI stopped responding LG S5
I followed the instructions on the link you sent me and it put it in safe mode. I'm not sure what else to try to get it in recovery?
