I haven't had it for very long and therefore don't know as much on the durability of the phone, but my previous Flip 4 was great for 2 years before it started having issues. (The phone had a literal dent in the metal) So far, however, everything has been better about the Flip 6 except one crucial thing: the ability to swipe down on the fingerprint sensor to bring up notifications. This feature was one of the things that kept me from getting a non-flip phone out of love for the versatile power button, but now I'll probably go looking elsewhere for my next phone unless this is brought back. Other than that major issue, it's a good phone.
Love this phone, this is my second flip, I literally wore the other one out. I like how this one is small and does not take up alot of room in my pocket. I also love how it can be folded and set on something flat for family pictures. Just an all around great phone, I love Samsung!
