IM Score: 15
If you want to go big, then 6.0 inches Gionee M6s Plus is a way to go. Unlike the most smartphones on the list of best Android phones with expandable memory in 2017, M6s Plus has a dedicated memory card slot allowing you to expand your memory with a microSD card up to 128GB (some sources say 256GB, so don’t take this as written in stone). You’ll also get octa-core processor, 6GB of RAM and 12MP primary – 8MP front camera combo. When it comes to storage, there are two versions you can get. One has 64GB of storage, while other has an incredible 256GB storage capacity.
