Pixel 3 sensor calibration, please can you share your experience?

Could people kindly do a simple test for me on their Pixel3 and ideally if they have another handset of any type. Can you turn on the grid within the camera app, take a picture of a level object (such as a PC monitor) with the handset placed on a level surface and tell me do the gridlines look level with the subject you are looking at.

i have had two Pixel3 handsets and both have the same issue which i strongly believe is a gyroscope/orientation sensor issue.

See issue below, the object is level (as it should be) on the OnePlus 6T (as it is with an essential phone and pixel2) and slanting badly on the Pixel3.

This augmented with a test when i play RealRacing and the car steers left when on a level surface leads me to the sensor theory but it's now on two handsets and i wanted to know if the issue was more prevalent but perhaps people have compensated subconsciously.

For info my handsets are the Clearly White 64Gb and both were from Three UK (delivered 40 days apart).

I failed to see how orientation sensor has anything to do with grid line or photo sensor.
 
The grid is drawn equally to the screen. Nothing to do with orientation sensor status though. The only use of orientation sensor is to detect whether you are taking a portrait or landscape orientation photo. So that will be 0 or 90 degree. Any orientation sensor will do, even the badly calibrated ones.
 
Just guessing but I think the OP is using that as an alignment aid. I personally don't use s grid.

Yes correct, i'm just using the gridlines as an illustration to show that when the phone is level the camera app has the picture at an angle. Hence the phone and the software (such as the camera app) believes it is level when it is not and i have to hold the Pixel3 at an angle (3-4 degrees) to get a level photo. This ties in with the issue on the game where the steering method is the phone sensors and when the phone is dead level it steers left.

Thanks, if that's the case why does the unlevel picture tie in with an issue when playing games where the phone is level but a game such as RealRacing thinks it's tilted left (and thus steers left). The software is taking a reading from a sensor on the phone to check whether it's level or not. This might not be the orientation sensor but another one and i think the camera uses the same one.
 
Have you made sure that the camera lens (not the phone body) is perfectly centered on the object you're using for your test? P3 lens is about as far away from the center of the phone body as possible. Have you also tried turning the phone a little to the left or right to see how that turns out?

From your pictures, it looks like the bottom one is not turned "flush" to the subject. A slight turn of the phone to the right looks like it would level it to the grid.

I don't have an answer for your issue with RealRacing.

Not related at all. From the pic you posted, I guess your phone is not perfectly potinted to the object and hence it is not capture the leveled line. The lens on the P3 is on top corner and the picture shows your right side of the phone is forward a little. Hence slanted line.

But it still has nothing to do with your orientation sensor. At best, it shows your photo sensor is not aligned properly. But I'd suggest you try again. Make sure your phone is perfected porpendicular to the line you try to capture.

The sensors should not have any impact on the camera except for image stabilization.
