MobilityArena Buyer’s Guide Verdict

The specs and features of UMIDIGI A3S are quiet decent for the price being offered. The double-sided 2.5D curved glass and metal frame design, along with 2GB of RAM, 16GB storage, and a 3950mAh battery is a repectable combination for the price.

Having “global LTE bands” means that the A3S is one of the few smartphones that can be used in almost any country in the world – including countries with network carriers that deploy CDMA wireless technologies.

There are not a lot of phones in its price range that offer the value that it does. At the very least, it is an Android phone that you should give a serious look.

The 3GB RAM variant, UMIDiGI A3X, is also good value for money. Users who want smooth app launching and switching should spend the extra $10 to purchase it.
