Many times, it so happens that your Android phone’s auto rotation stops working. And there are quite many devices that do not provide the option of calibrating the G-sensors. What do we do to solve this? Here is a solution I happened to come across by hit-and-trial.
Requirements : a rooted phone, better if it has CWM Recovery. Those who are not understanding a word from either of the above, please stay from this article.
Steps
1) If u do not have a working CWM, then you will be required to download an application called Titanium Backup / Pro.
2) Allow the application the SU (Superuser) right.
3) Select the options menu, tap the option that says Clear Dalvik Cache.
4) Reboot you android and this should work!
Same can be done using Link2SD (PlayStore link provided : app is free).
Now those who have a working CWM and do not want to download any app, go to the recovery mode, select advanced using volume rocker buttons to scroll and power button to select, similarly select Clean Dalvik Cache.
This should help in getting back your auto-rotate.
If this does not work, then create a backup of all your app using Titanium Backup, factory reset your device.
And if neither this work, I am afraid, service center is the only resort. And to see how your Android can be tuned into a webcam, follow our post here.
