AT&T is one of the Worst mobile carriers for Android hardware. I had a Samsung S6 EDGE+ sm-g928A variant. 32gb in Gold Platinum. The problem is AT&T loads so much bloatware on the phone, it makes it almost unusable. You cannot root this phone. Additionally there hasn’t been an update issue since December of 2015. It’s now May of 2016!
Amazon Trade-In’s offers you cash in the form of Amazon gift card for your old devices. This is a great way to recycle and reclaim value for items that would otherwise just be collecting dust.
In an effort to use products that are more sustainable, I have banned AT&T phones from my life. I will continue with a Blackphone 2 and One Plus Two.
