Google Pixel 4a Ambient Sensor Shows Issues: Fluctuating Readings on The Sensor May Cause Problems in Adaptive Brightness Control

The Pixel 4a is yet to come to regular people but seems like certain reviewers see some issues already. The newest, budget device from Google was a hit amongst the reviewing class. This is primarily because of the amazing image sensor onboard and the budget price tag. Not to mention, Google also added a better battery which actually solves most of the issues previous Pixel devices used to have. But, what can be said about the device itself. It is true that coming in at $349, the device is pretty good for the price. Though, we should also focus on certain corners the company would have cut to actually bring the price so down.

In a tweet from Ron Amadeo, who also read reports online, the person claims that the brightness sensor for the Pixel 4a is flawed. Of course, Google uses AI very liberally and thus phones would be more reliant on the usage than the lighting conditions to train the device. But, there seems to be an issue with the sensor itself.

The video embedded with the tweet shows the sensor compared to another device. The raw brightness readout app shows how the sensor would read light to adapt its screen brightness accordingly. This shows quite a huge problem as the device’s sensor fluctuates readings constantly in a stable setting. The author of the tweet comments that this would obviously affect how the AI is trained in the background as well.

Now, it is unsure whether the sensors are at fault or if there is a glitch in the software side. Either way, Google will have to solve this issue which would render these devices having variable battery times, according to the fluctuating brightness adjustment.
