I got my GX4 in February. The day after I got it, it just randomly shut down. Home button flashing, screen will not come on, will not manually restart. After about 5 mins, it started back up. All was good for another month or so.. Then I needed my shopping list in Walmart (I use Keep), and wouldn't you know, phone does it again. Most recently, while at work, I picked it up to get directions for a customer, and it was just off too. I don't know why, any help?
Also, first time I had no apps running and believe I was trying to use calculator. I always wipe my apps after use so they aren't in background.
