Oppo A77 5G test: an inexpensive smartphone and record autonomy

The Oppo A77 does not overbid in photos. On the back, there is a double module consisting of a 48-megapixel sensor with wide-angle optics and a 2-megapixel depth sensor. No ultra wide-angle here, therefore.

The Samsung Galaxy A33 5G has a fairly similar main sensor. Both devices use the technology of the pixel bindingwhich involves merging four pixels into one, to capture 12MP shots.

Main module: 48 MP, f/1.7, eq. 26mm

By day, the Oppo A77 delivers a shot of good quality. The rendering is very contrasting and reveals a little more detail than that of the Galaxy A33. Samsung’s mobile opts for a more saturated colorimetry, which should nevertheless flatter the retina when viewing on screen. Nevertheless, the South Korean model forces a little too much on the digital smoothing, and sometimes gives the impression of lacking sharpness.

This spoils for both smartphones as soon as the light runs out. The Oppo A77 once again retains a very slightly higher level of detail and contrast than the Galaxy A33, even if a particularly visible digital noise appears, and the tint of the image turns yellow. The more pronounced smoothing of the Samsung has the same effect as the day shot: the image lacks detail. Note, however, that the scene remains readable on both, which was not the case with entry-level devices a few years ago.

48 MP mode

It is still possible to take photos in 48 Mpx via a turn in the settings.

Whatever the lighting conditions, switching to full definition is of little interest. The gain in detail is minimal and the colorimetry unchanged. It may occasionally be used to resize a snapshot.

Front and video module

An 8 Mpx sensor whose lens opens at f / 2 is housed in the notch at the front. It allows you to take rather satisfactory selfies, provided you do not move. The level of detail is good, the colorimetry quite natural, but the sensor still has trouble managing the highlights.

The smartphone is capable of filming in Full HD at 30 frames per second. It is clearly not aimed at videographers, but it is still possible to achieve decent shots despite limited stabilization.
