The BLU Vivo XL4 is a 6.2-inch Android handset with a MediaTek Helio P22 processor inside, next to 3 GB of memory and 32 GB of internal storage space. Sporting a generous 4,000 mAh battery (thankfully featuring 5 V/2 A fast charging) and a 13 + 2 MP main camera setup, this handset can be acquired from Amazon for US$149.99.

Please be careful if you are interested in purchasing this phone. I have had two different Blu phones over the last few years, the R1 HD and now the Vivo xl3 plus. I have no issues with the phones themselves. In my experience, they were just as advertised. However, the real issue is with Blu support and development. In all my years of experience with them, I have never seen them update any phones, even though they advertised the fact that they would. In fact, with the xl3 plus, they promised in their Amazon ad that they would be updating the 7.0 nougat with 8.0 Oreo. So, if you buy the xl4, just know that you're stuck with 8.0. There's no updates coming, regardless of what they say. Buyer beware!
