Display and Design
Oppo has equipped the A78 4G with a 6.43-inch AMOLED punch-hole display running at a 90Hz refresh rate and a resolution of 2400 x 1080 pixels. The screen is protected by Gorilla Glass 5, offering solid resistance against everyday scratches and minor drops. An in-display fingerprint sensor keeps the front face clean and uninterrupted. The phone is available in two colour options — Sea Green and Black Mist — giving buyers a choice between a vibrant and a more understated aesthetic.
Performance: Snapdragon 680 and RAM Expansion
At the heart of the OPPO A78 4G sits the Qualcomm Snapdragon 680 octa-core processor, running Android 13 under Oppo's own ColorOS 13 skin. The phone ships with 8GB of physical RAM, but Oppo's RAM Expansion technology can borrow up to an additional 8GB from the internal storage, effectively pushing the available memory to 16GB. Paired with 256GB of onboard storage, users have ample room for apps, games, and media without worrying about running out of space quickly.
Camera: 50MP Primary Lens with Portrait Mode
Photography on the OPPO A78 4G is handled by a dual rear camera system. The main shooter is a 50-megapixel sensor with an f/1.8 aperture, designed to let in plenty of light for sharp, detailed shots. It is paired with a 2-megapixel portrait lens to add depth and background-blur effects to close-up shots. On the front, an 8-megapixel selfie camera takes care of video calls and self-portraits.
Battery and Charging
The OPPO A78 4G houses a large 5,000 mAh battery, comfortably handling a full day of mixed use on a single charge. When it does need topping up, the phone supports 67W SuperVOOC fast charging — one of the faster charging speeds in this price bracket — meaning you spend significantly less time tethered to a wall outlet.
Price, Availability, and Free Gift
The OPPO A78 4G is available in Indonesia in a single memory configuration: 8GB RAM + 256GB storage at IDR 3,599,000 (roughly ₹19,500 in Indian currency). As a launch incentive, Oppo is bundling the OPPO Enco Buds 2 wireless earbuds free with every purchase of the A78 4G. For more phones from this brand, explore the full brand section on our site.
