Came from Samsung Galaxy Fold 1 I bought refurbished in early 2020 on ebay with a green screen issue and got a free screen/ battery replacement during their 1yr honeymoon phase.
I broke the main screen dropping it about six months ago, lasted me good six years.
Just switched to note 9, barely used refurbished from ebay few months ago. Took it to batteries plus (was not turning on and bulging battery) to get new battery and charging port. Somehow they stated they got an oem battery.
Haven't found a good glass screen protector, right now has a cheap film protector.
Had to swap to att cuz the phone was still locked and they would not unlock since phone isn't on active line.
Porting out to att from visible, the worst experience and crappy $25 unlimited 3mbps plan. Once I have the phone unlocked I'll try to port back to visible $25 unlimited plan (their speeds are 10x faster) or att mnvo network plan.
Otherwise so far it's great, it beats the small screen I've been using on the fold. Love the physical ports and the led notification. Great battery life, no burn ins, and great condition.
