Hi to all. I need to add a function detecting when the phone is horizontal. I downloaded from GooglePlay some programs that do exactly what I want, so I argued that I can implement something about my problem, accessing Gyroscope sensor, that seems to be the only sensor able to detect phone position. With my surprise, while the downloaded apps work on my phone, the B4A example found here says that no Gyroscope sensor is available. I did nothing but compiling the example found here. I tried probably all the examples found in this forum, and no one works. Actually they are (very) old. So maybe Android changes are responsible for this situation or am I missing something ?
