Point question

[JackZhang1994]

Why is the point so unstable? It doesn't stop moving in the screen, and then it shows off for a while, and I don't have a mobile phone. Can you answer my question? Thanks~

Please check your phone whether has compass and accelerometer sensors

Here regist a sensor listener. And it can go into this method.

In OnDraw(Canvas canvas) method, I set a log. And this is the result. A large change in coordinate points, and why?

[JackZhang1994]

My device is MEIZU M5, and another is One Plus 5.

Because I set SENSOR_DELAY_GAME flag in sensor register listener, it probably depends on devices, but I think sensor trigger and frequently update value for each 37-39 mili seconds

Well, what I mean is x:826~863 y:154~201 but I didn't move my device.

[JackZhang1994]

Ehnnn, what I mean is... When I fix the cell phone, the value of X and Y is still changing, the range of the change is 50. What is the cause? Do you have a way to solve it? And another question, when I set up difficult altitude, the location of the point is always in the center of the screen, just like no altitude. Can you tell me why? Thank you very much~

[ShantiRanjanDas]

Yes, I have also the similar situation. The points are moving and are not on a particular position, While I move my phone they also move, but they must be in one position.

For my case, i had no problem with Xiaomi Mi A1 running Nougat. After updating to Oreo this started happening...
