Oppo R1x Review
Adequate image quality and tons of features
Oppo has outfitted the R1x's main camera with a 13-megapixel Sony Exmor RS IMX214 sensor. In general, we liked the imagery, though the lack of OIS meant that once lighting became less-than-favorable, we had to keep our hands exceptionally still in order to not blur the photos. Most photos look neutral in terms of white balance, objects in focus are sufficiently sharp, and digital noise is easily visible, yet within tolerable limits. On rare occasions, however, you might end up with a slightly blurry image – if your hands aren't steady enough, or if the camera fails to nail the focus at the right point.
Recorded videos end up being colorful, but not very detailed. Even normal movement tends to distort or tear up the objects, making them hard or just unpleasant to follow. The clips end up having a pretty high contrast, resulting in dark spots in the scene being completely blacked out, and light sources being blinding white. Audio is also not the best, as it lacks depth and is slightly muffled. In general, you will probably avoid relying on the R1x as a video recorder.
The selfie snapper is a 5 MP one and we found that it does a good job at capturing face details. Switching to the frontal cam will automatically put the camera app in “Beautify” mode, giving you a choice of 8 filters to apply to your mug shot.
A nice picture, but sub-par sound
The 720 x 1280-pixel resolution lends itself to a good viewing experience, providing a good amount of detail and sharpness on the 5” display. Watching a movie was slightly irking, as we were haunted by the feeling that we could never get the brightness set to perfect viewing conditions, and we assume this was due to the display's slight lack of reds and uneven gamma. That aside, when checking out pictures, viewing clips, or playing games, all looks good on the Oppo R1x.
The speaker can't be relied on for proper audio reproduction. It has a pronounced hump in the mid frequencies and a definite lack of depth, so don't expect to be getting any pleasureful ear-filling sound effects, drums, or bass. Otherwise, it's loud enough and does its job right when it's time to deliver alerts and rings.
