Tablet [Q] problem with gyroscope, light sensor and auto rotation

Firstly , I would like to apologize if I posted in the wrong place ... I'm new to the forum. I would also apologize because I am Brazilian and I'm using the google translator .

I searched the forum and have not found a solution to my device , then searching the web I saw many users praising the XDA , so I came to seek a solution to my problem here , I hope you can help me !

My tablet Galaxy tab 2 7.0 " suddenly stopped working the gyroscope , a light sensor and the screen does not rotate in landscape mode . Already done everything and does not work . Only play with apps in store . Before but now it worked normally .

I downloaded an app called phone tester to test my sensors but only appears "waiting for data ... "

Is there any way to enable these features ?
