[SOLVED] Any idea how to know if real sensors exist ?

[lemonisdead]

Hello,
This message is a bit oriented and I do apologize for this. I recently wanted to test an app using the gyroscope on my Oukitel (which is described as incorporating that sensor on the manufacturer's web site) and got the "-1" value... I tested it with some other app and the sensor was missing.
In the same time, I did see that the magnetic sensor did not return any value. And saw that the manufacturer do sell a pack incorporating a VR set, so the device should have a gyro (I think).

Well, so I decided to buy another phone for my testing, described on the manufacturer's site and the reseller's site as having the g-sensor. Guess what, it didn't. Same topo as the first one, the g-sensor wasn't existing and the magnetic one returned no data.

So, I bought a third one, from another brand, and it returned the values I was expecting to get.
The main difference between it and the first two was the chipset : it has a Qualcomm and the others a Mediatek.

So, I am trying to understand if the manufacturers do lie about the capacities of their products or if there is, perhaps, another reason ?

Thanks for any information (my google searches did not provide many information).

Have you tried contacting the seller or producer?

Yes I did before requesting a refund and returning the products each time. Their replies were that the product did include the missing sensors.

If a faulty device could be the reason, I should be the less lucky person in the world. But perhaps is it the real reason

MediaTek has gotten some bad news lately. MediaTek says it only applies to their KitKat phones.

"MediaTek software has a "backdoor" that allows a user - or a malicious app - to enable root access. The problem, as Case explained, is a user or a malicious app can change the usually restricted and read only properties on the device, which "can trivially lead to privilege escalation to the root user.""

The "g-sensor" is the accelerometer, and not a gyroscope. If you are taking about the oukitel k6000pro then I don't think it has a gyroscope.

I really have to warmly thank you @Widget because it was not obvious for me that it was only the accelerometer. I was talking about the K10000 and Doogee X7Pro but your reply has cleared my lack of understanding.
Many thanks
