The BLU Life One X is perhaps the cheapest, decent Android smartphone you can buy right now. Today, Amazon has it as part of their Gold Box Deal of the Day for just $99. Normally this thing sells for about $149, effectively making this 33% off, today only. You'll want to hurry as this price will end at midnight.
What we have here with the BLU Life One X is a 5.2-inch HD IPS display, powered by a quad-core processor, 2GB of RAM, 16GB of storage, a microSD card slot, along with Android 5.1 Lollipop. It does use micro USB for charging and not USB Type-C. The BLU Life One X also does support LTE, something that most of their phones don't do. However it does support bands for T-Mobile and AT&T, which means it will also work on their MVNO's like Straight Talk, Simple Mobile and many others. Here are their 4G Bands 4G LTE, (2/4/7/12/17), 4G HSPA+ (850/1700/1900/2100). It comes in both black and white, we did review the BLU Life One X last December, and found it to be pretty decent for under $100, and at this price, it's hard not to recommend it, especially for someone that just needs a phone that works.
