[AC Question]

A few days ago I noticed that when I go into landscape mode my huawei p7 did go into landscape but to the wrong way so I downloaded an app and my x goes from -20 to +20 when I'm holding it straight! I already tried dropping it but that doesn't work so I hope i can get an answer here.

if this happened after a fall it could have damaged something but it may just need to be calibrated. I'm not sure for your model but for android in general look in settings>display & gestures, and there you should find a G-Sensor calibration option. Try that. If that doesn't fix it you may be able to find a reset option for it inside the phone, but you'll have to Google for the access to those functions. Usually the code is something like ##64219## and then send, from the dial pad/keypad. Be careful if you go this route looking for anything, because changes in this area can have serious affects on how your device works and responds.

FYI the code mentioned is generic and doesn't necessarily refer to any device.
