The Samsung Galaxy Note 4 was the last Galaxy Note to feature a microSD card slot and a removable battery. In 2015, Samsung removed those features from their Galaxy S and Galaxy Note line of flagships, unfortunately. Many users loved having those two features on the Samsung flagships, and well they'll have to settle for the Galaxy Note 4, which is currently on sale over on eBay for just $399. That will get you the unlocked AT&T variant. However, if you are on Verizon, the Verizon variant is going even cheaper (under $300 actually). Making it a great deal for those that are on Verizon.
Samsung's Galaxy Note 4 might be getting a bit long in the tooth, but its specs can still stand toe-to-toe with today's latest and greatest smartphones. Like the Galaxy S6, or the Galaxy Note 5. Here we have a 5.7-inch 2560×1440 resolution display on the Galaxy Note 4. It's powered by Qualcomm's Snapdragon 805 processor along with 3GB of RAM and a fantastic 16MP camera around back. Not to mention the removable 3200mAh battery that is powering the Galaxy Note 4. Now this is the AT&T variant, but it will work great on both AT&T and T-Mobile, for those that are looking to use it without signing another contract or having to pay installments for the device.
