Oppo appears to have hiked the prices of Oppo K14, Oppo K14x and Oppo A6s smartphones in India by up to Rs. 4,000. The likely reason behind this price change is the rising cost of memory chips. The Oppo K14, Oppo K14x and Oppo A6s ship with the MediaTek Dimensity 6300 chipset. They feature 6.75-inch displays and dual rear camera units headlined by a 50-megapixel primary sensor.
