Ulefone BE X is another smartphone under $100 with very good hardware like octa core CPU. Except MTK6592M it has 1 GB of RAM and 8 GB of internal memory with microSD card slot. It has 4.5 inch qHD LG IPS OGS screen which looks great.
It comes out of box with installed Android 4.4 and it has 8 megapixel main camera with LED flash. Ulefone BE X has a really nice design and it looks really cute. I think you will like it and in my personal opinion this is a great choice for buying in this price range because the price is only $89.99. If you decide to buy it you can do it here.
