UMIDIGI A3 Overview
UMIDIGI A3 has a bright and clear (resolution of 1440x720) 5.5 inches-inch display and dimensions of 147,2 x 70,2 x 8,5mm. It also only weighs 186g. The main specifications are the MediaTek CPU - MT6739, 16GB storage and 2Gb RAM.
The UMIDIGI A3 release date is September 2018. The Omnivision OV12870 rear camera with a 12Mp sensor takes great pictures, and the 8Mp front camera is designed for selfies. The price of the smartphone is very cheap and this cost is the best deal right now, so it is worth buying and this will be a good purchase for anyone who is used to using Android 8.1 OS.
The UMIDIGI A3 has Dual SIM card slots, you can have 2 numbers from different carriers.
Internet speed will be standard because there is no 5G support.
UMIDIGI A3 has support for expandable storage, so you can insert SD cards as soon as you need to.
A standard headphone jack will save you money since you can connect any 3.5 mm port headset without adapter.
You can’t make mobile payments with UMIDIGI A3, because it doesn’t support NFC.
You can't use it as a remote control, because it does not have an infrared (IR) blaster.
UMIDIGI A3 already comes with a 3300mAh battery without the need of fast charging or wireless charging. Most competitors do not have this feature.
The device is not waterproof. We do not recommend taking it into the shower or the bathroom, or using it in the rain or snow.
