Title of the thread says it all. Jet Black iPhone 7 Plus 128gb. I've been using it for about a week, no issues. (Minus an annoying lag whenever I back out of any app.) However yesterday, I had an issue where I lose all functionality in the home, volume, and lock buttons. Today I had the same issue pop up. It lasts until I try to do a hard reset, where nothing happens for a few seconds and then everything tries to function at the same time. Volume spikes go up and down. IPhone takes a screenshot, lock screen goes in and out, and then everything returns to normal. Anyone else experience this yet by chance?
