IF you are rooted then
Use es file explorer and change the build.prop line carefully.
First click on root explorer and again give permission to m/w
Then in system/build.prop change this line.
ro.sf.hwrotation=180,270 or 0 also can help.
If there is sensor file problem then ask the developer for bug fix.otherwise above solution m8ght help
