Oppo has been able to leave its mark in the smartphone industry. Be its massive advertising campaign or its unique marketing strategies, people have started buying their smartphones. They have been producing budget segment smartphones too, apart from their high end flagship devices. Adding yet another smartphone to its long list of smartphones, Oppo launched its “Oppo A31” smartphone. The phone featured as an entry level smartphone, a segment famous for its cut throat completion.
The Oppo A31 is a decent looking smartphone with its smooth front and back panels. About the general geometry of the phone, the volume rocker has been provided on the right edge of the phone and the power button has been provided on the left edge. The speaker has been provided on the bottom part of the back panel. Three soft touch capacitive buttons are provided on the bottom part of the front display. The external dimensions of the phone are 131.9 x 65.5 x 8 mm (5.19 x 2.58 x 0.31 in) and it weighs around 135 grams. The phone is available in two color variants i.e. White and Blue. Talking about the display provided in the phone, it comes with a 4.5-inches IPS LCD capacitive touchscreen has been provided in the phone that provides a screen resolution of 480 x 854 pixels. The display does a decent job and serves its purpose. Though the screen looks a little warm, the viewing angles as well as the sunlight legibility are decent. Overall, the phone has an average design and decent display.
The phone is powered by a Quad-core 1.2 GHz Cortex-A53 processor mounted on a Qualcomm MSM8916 Snapdragon 410 chipset. The processor provided in the phone is capable of providing a decent performance, but then again one cannot expect it to play heavy 3D games and videos without encountering some lag. The Adreno 306 GPU provided in the phone makes sure that games and videos easily. The 1GB RAM provided in the phone gets the job done, however, the phone simply cannot handle serious multi-tasking. The A31 is designed to be an entry-level phone so we weren’t expecting the phone to perform top-class either. The phone comes with 8GB of internal storage, which can be further expanded up to 256GB using a dedicated microSD card slot. The phone runs on Android platform, v4.4 i.e. KitKat with the help of Oppo ColorOS. The Oppo A31 is a dual sim phone that supports 4G/LTE networks.
The phone features with an 8MP primary camera that is backed by autofocus and LED flashlight. The front shooter on the other hand features a 5 MP Selfie camera. The primary camera comes with features like Geo-tagging, touch focus, face detection, panorama and HDR. Taking a look at the overall picture quality of the camera, we can say that the images captured by the camera are decent. The images captured by the rear camera capture a lot of details but are not exceptional. The images captured in dim light conditions are not good as a lot of noise seems to creep in the photographs. The 5MP selfie shooter can take decent selfies, but would be more useful for video calling. The videos are recorded on the phone at frames like 1080p@30fps. The loudspeaker provided in the phone gets loud enough and a 3.5mm audio jack is also provided in the phone.
The Oppo A31 comes with a non-removable 2000 mAh Li-Ion battery. The battery promises Standby time for up to 240 hours and talk time up to 420 mins. In real life conditions, the battery runs for a day with moderate to heavy usage. The battery doesn’t support quick charging but supports multiple battery saving profiles. The phone comes with WLAN Wi-Fi 802.11 dual-band, Wi-Fi hotspot, Wi-Fi Direct, Bluetooth version 4.1, A-GPS and micro USB v2.0. The phone comes with sensors like accelerometer and proximity sensors. The messaging section of the phone has been kept as the SMS (threaded view), MMS, Email with an HTML5 Browser and no java facility.
