I have a oppo A 83 mobile phone. Ihas many features like : 5.7-inch IPS ( 1440 x 720 pixels) , octa core Mediatek Helio P23 processor, 3GB RAM, 32GB storage, microSD slot for storage expansion ( up to 256GB supported) , dual nano SIM slot, 13MP f2.2 rear camera with LED flash, 8MP f2.2 front camera, 4G, VoLTE, dual band WiFi, Bluetooth 4.2, GPS, Android 7.1.1, 3, 180mAh battery etc.The A83 is Oppo’s first sub Rs 15, 000 offering with an 18: 9 aspect display. They have the premium Oppo F5 which features a 6-inch screen, but this budget A83 has a 5.7-inch display. The benefit of this is that the size of the phone is about the same as a 5.2-inch device which makes it easy to handle. Add to that the fact that the phone is just 7.7mm thin and weighs 143 grams. We loved the matte finish on the back as it gives the phone a better grip and feels great to hold.
The screen impresses with slim side bezels, vivid colour and excellent brightness — it is easy to read under direct sunlight too. It comes with a preapplied screen guard which is always a welcome addition. The screen resolution of 1440 x 720 pixels keeps content fairly crisp but there are now cheaper phones with 6-inch, 18: 9 screens that have a higher resolution of 2160 x 1080 pixels. This immediately started making the A83 feel overpriced. It is reliable.
