Frequently Asked Questions
What is the battery life of the Oppo A31?
The Oppo A31 has a 4230 mAh typical battery (4100 mAh minimum), which gives it enough power for a full day of typical usage—calling, social media, and video. When used heavily (gaming, video streaming), battery will drain faster. The phone charges via 10W micro-USB and does not support fast-charging beyond that.
Does the Oppo A31 support fast charging or high-speed charging?
No, it doesn’t. The charging rate is standard 10W via micro-USB, which means charging from near empty to full takes longer than phones with fast or super-VOOC loaders.
How good are the cameras on the Oppo A31?
It has a triple rear camera setup: a 12 MP main sensor (f/1.8), a 2 MP macro lens, and a 2 MP depth sensor. The front (selfie) camera is 8 MP. Daylight shots are passable for basic photography, but low-light performance and video detail are limited.
What display, build and durability features does the Oppo A31 have?
The A31 uses a 6.50-inch IPS LCD display with HD+ resolution (720×1600), giving about ~270 ppi. The front is protected by Gorilla Glass 3, while the back and frame are plastic. There is no official IP rating for water or dust resistance.
What software does the Oppo A31 ship with, and what update support is available?
It ships with Android 9.0 (Pie) and Oppo’s ColorOS 6.1. There is no strong evidence of significant OS upgrades beyond minor patches; many users report the phone remains on ColorOS 6.1 years later.
What are common issues or known limitations with the Oppo A31?
Users report relatively slow charging and that the phone lags under heavier multitasking. Also, storage glitch issues have been reported (e.g. deleted files sometimes still taking up space). The camera lacks advanced stabilization or features, and low-light shots are weak.
What network, SIM, and connectivity options does the Oppo A31 support?
It supports dual nano-SIM (dual standby) and 4G/LTE networks across many bands. Connectivity includes WiFi (dual-band), Bluetooth 5.0, a 3.5 mm audio jack, FM radio, GPS/GLONASS. There’s no 5G, and NFC is absent in many regional variants.
What is included in the box with the Oppo A31?
Standard inclusions are the handset, USB-A to micro-USB cable, basic charger (10W), SIM ejector tool, and user documentation. A protective case is not guaranteed in all markets; confirm with local Silkroom Electronics stock.
How secure are its unlocking & biometric features?
It has a rear-mounted fingerprint sensor plus a 2D face unlock (using the front camera). The fingerprint sensor works reliably in normal conditions, though not instantaneous. The face unlock is convenient but less secure compared to more advanced biometric systems.
