ZTE Max XL is great because it has fingerprint sensor, however many customers complain about average performance which is especially true given that it costs $99.9.
LG X Power is great because it has decent performance with RAM 2GB, however many customers complain about low resolution camera which is especially true given that it costs $84.
The Acer Liquid Z410 is one of our top picks, owing to nice design. However, we knocked off a star because of screen size 4.5". Still, with good performance it easily makes it into our list of recommendations.
Samsung Galaxy J3 Emerge at a price of $92 is one of our favorite smartphones below 100. Boasting nice camera and good battery life, it's only let down by small RAM 1.5GB
Looking for a Smartphones below 100 with decent performance.. AND solid design and build quality? Then you need BLU R1 HD. One of the best in its category, this comes highly recommended.
