My phone fell down yesterday and afterwards I couldn’t rotate it anymore. Also when watching 360° Videos, I cannot look around anymore. I installed an app to get sensor data, and it’s not showing an accelerometer – and there should be a rotation sensor as well, right? Did that chip unplug when the phone fell down, so that the device is not recognizing it anymore? Maybe it’s just broken? How can I find out, and is it possible to replace that unit? Thanks guys!
After opening the phone (which is a breeze) I realized that the sensors seem to be on-board. So I tweeted to BlackBerryHelp and they told me to install a analysis app, which reported the sensors to be broken. That way I could send the phone in and have it repaired.
