The Xiaomi Redmi 4A is powered by a 1.4Ghz quad-core Qualcomm Snapdragon 425 processor, and though not ideal, it is what you should expect at this price point. The phone has two variants. One is a 16GB variant while the newer one is a 32GB variant. The 16GB option comes with 2GB of RAM while the 32 GB variant comes with 3GB of RAM. The internal storage can be increased up to 128GB via a microSD card. As far as the cameras go, The Xiaomi packs a 13-megapixel primary rear camera and a 5-megapixel front camera for all selfie needs. The body is made entirely of plastic and has a uni-body design. It looks like a decent metallic finish thanks to the uni-body design but feels rather light and slippery. So a screen guard and decent phone cover should also be included in your list of expenses when you purchase this phone. Overall it seems that Xiaomi could have done a better job with the body and the specs, but then again, a price point this low can only get you so much, and by no means are these terrible specifications for a phone at this price.
The Xiaomi 4A comes with Android 6.0, and the Xiaomi Android ROM does an excellent job when it comes to the 4A. There are a lot of baked in Xiaomi goodies to enjoy, and the Xiaomi style, even on a budget LCD screen looks gorgeous. You can make use of the Xiaomi theme engine and tweak pretty much every UI detail. The user has been provided with quite a bit of control to improve the overall experience. The contrast is manually adjustable. The Redmi 4A also has an automatic brightness which is a big deal for a phone at this price point.
The phone is powered by a 3120mAH non-removable battery. While the battery may seem decent, it does fall short when compared to other phones. The phone could have come with a higher powered battery, but having said that the phone does have decent battery life. Apart from 4g and VoLTE the 4A also supports Bluetooth 4.1, WiFi, GPS/AGPS, and GLONASS. The phone is also equipped with a hybrid dual SIM slot which can hold one Micro-SIM and one Nano-sim or a microSD card at one time. When two SIM cards use the primary SIM card supports 4G calls and data while the secondary SIM supports 2G calls only. The sensors included with the phone include a gyroscope, accelerometer, proximity sensor and an ambient light sensor.
The Redmi 4A sets the cat amongst the pigeons at this price point, and you should expect this phone to be somewhat popular. The 4A offers a lot of features; the camera is relatively decent, the polycarbonate body, battery, and software are very satisfactory. The phone seems like a decent option for first-time smartphone buyers or anyone who is on a budget but wants a phone that packs in a decent performance and comes with some suitable features.
