First some background: I've only had Motorola smartphones. I never had a single problem, so I didn't hesitate to buy another one when I wanted to upgrade. My most recent was a Moto X 2nd Generation which--after four years of perfect service--started having battery problems. After buying a replacement battery and tools...yeah...these old eyes weren't about to attempt the repair on my own. So I bought a new Moto Z² Force Edition instead! Now that's where it starts getting weird. The very first time I used its default camera app to take a picture, it crashed. Like 'restarted the phone by itself' crashed. Odd, I thought. Then I installed my normal camera app, A Better Camera Unlocked, took some pics with it, no problem, so I chalked it up to a fluke. But then other stuff happened, including screen burn-in (which I didn't even think was still a thing!), despite never leaving the screen on and idle for long periods. So in May, I got off my lazy ass long enough to call Motorola and ask for a replacement (it was under warranty), which arrived a couple days later. And guess what? No weird problems! It's been a month+ and everything's as I expect with a Motorola phone. I think I simply got a lemon with the first one. And, if anything, this whole experience actually made my loyalty to Motorola even stronger. There was a problem, they resolved it quickly and painlessly, and I'm happy with my phone. Can't ask for more than that! PS I still use the Moto X--I just keep it plugged in all the time. No problems, and it's over 4 years old. ETA PPS: I totally forgot to say that the replacement phone's battery lasts HOURS longer than the lemon's! Like 8+ hours longer, under the same usage conditions. Nice!
