It has been a widely reported and worst kept secret that Pixel 4 would be the first Pixel smartphone to come with multiple cameras. Google is all set to break its trend of using only a single shooter on the back panel and now, a new XDA Developers report sheds some light on what kind of sensor we should expect in addition to the standard sensor.
The report is based on the Google Camera v6.3 source code references suggesting that Pixel 4 could come with a 16-megapixel telephoto sensor. It is the same app version which was leaked along with an unreleased Android Q beta build last week. The references to a new sensor type were found within the code meant for Pixel camera app's Super Res Zoom feature.
It should be noted that this particular feature is internally referred to as sabre which is what is used within code lines. The XDA folks spotted a new reference “SABRE_UNZOOMED_TELEPHOTO” which they were quick to take note of. During further investigation, they were able to unearth new camera sensor IDs which are missing in Google Camera v6.2 code lines.
These newly spotted camera sensor IDs are Front IR, Front Wide, and Front Regular along with Rear Regular and Rear Telephoto sensors. The team believes if the "IR" in Front IR stands for infrared, then it could be related to some kind of infrared-based facial recognition technology.
As for the possible telephoto camera resolution, it has been discovered by 9to5Google folks during their own investigation. They spotted a text line, “Telephoto image has dimensions ( ), but should have dimensions 4656×3496, 4656×3492 or 2328×1748.” This is what led them to believe that we could see a 16-megapixel telephoto camera on Pixel 4.
But as we always say about features spotted or anticipated through Android app APK teardowns, one should not take anything for guaranteed. There is always a possibility that none of these might come true for any reason. We would be sharing more details with you as they will surface.
