As per a new leak, the OPPO A15 will be powered by a more powerful MediaTek Helio P35 processor (instead of Media Tek Helio G85 chipset). Moreover, the base variant will have 3GB RAM and 32GB of inbuilt storage.
Need to wait for further confirmation on the other variants of RAM/storage options.
The Amazon leak also reported that OPPO A15 will have a 6.52-inch display with HD+ resolution and 5mp selfie snapper. Even there’s a correction regarding the battery. It will be backed by a 4,230 mAh battery.
