The OPPO Reno4 presents a coherent mid-range formula: a slim 165g body, a 6.4-inch OLED display, a 48MP rear camera and fast wired charging. It is not trying to establish a single extreme specification. Instead, the supplied hardware points towards a balanced phone for buyers who value screen technology, camera flexibility and manageable physical dimensions.
A focused display and design
The 1080 x 2400-pixel resolution gives the OLED panel a detailed foundation across its 6.4-inch surface. OLED is also a clear part of the phone’s identity, making the Reno4 a straightforward choice for buyers who prioritise the display type itself. At 7.7mm thick and 165g, the dimensions indicate a relatively restrained physical design on paper, while the glass front keeps the construction from being entirely plastic. The plastic frame and rear, however, define a material trade-off: glass is used only on the front rather than throughout the exterior.
The Galactic Blue and Space Black finishes provide two specified colour options. That is a modest but clear presentation, with the product’s design emphasis resting more on slimness and weight than on an expansive materials specification.
Camera hardware with two rear viewpoints
The rear system combines a 48MP main camera with an 8MP ultrawide camera, giving the Reno4 two distinct lens roles rather than a single fixed perspective. The main camera’s f/1.7 aperture and 1/2.0-inch sensor size add useful technical context to its primary camera specification, although those figures alone do not establish real-world image results. A 32MP front camera rounds out the imaging hardware for buyers who place value on a high-resolution selfie camera specification.
This is therefore a camera arrangement with breadth in its listed hardware: a higher-resolution main unit, an ultrawide option and a separately specified front camera.
Sensible core hardware, defined connectivity
The Snapdragon 720G uses an octa-core CPU reaching 2.3GHz, paired with an Adreno 618 GPU and 8GB of RAM. Those components give the phone a substantial on-paper platform for its category, while Android 10 with ColorOS 7.2 supplies its stated software base. Storage is 128GB, a clear allowance for locally held content but also a fixed ceiling buyers should account for.
The 4,015mAh battery and 30W charging specification form a practical pairing. OPPO states that the charging system reaches 50 percent in 20 minutes, giving the Reno4 a defined rapid top-up capability without requiring assumptions about endurance. The decisive connectivity limitation is equally clear: this is a 4G-only handset, with no 5G support.
