Budget phones are cheap for one reason. Despite the way companies try to spin them, they will always lack any hardware that enables this or this feature. Sometimes such hardware happens to be something we usually take for granted. Like surrounding sensors that allow phones to automatically adjust brightness depending on the environment. Samsung’s budget Galaxy phones do not have it, but it seems that the company has found a rather curious way to get around that constraint. All it takes is to take a selfie.
No, do not worry, the phone does not take a snapshot of your face and sends it to Samsung’s servers. However, it will use the front camera to take a quick picture, whether your face is there or not. And according to Samsung’s message, the image will not be stored anywhere, not even on your phone.
Here’s how it will work. If you turn on the previously absent Auto Brightness feature on phones that do not have an ambient light sensor, the phone will take a picture every time you unlock the phone. That image will be analyzed to determine the light ratio at the given moment. Probably the image will be discarded immediately.
Although it seems to be a smart way to compensate for the loss of an ambient sensor, the way of adjusting brightness can not be so smart. It will match the lighting ratio analyzed from selfie with the brightness levels you have set. In other words, you must train it manually for a while before it starts doing things automatically.
Currently, the update that included this feature has been rolled out only to the Galaxy J8. Hopefully, it will also come to other phones in the Galaxy J series, but given this is Samsung, it’s very uncertain.
