For a project I am modding a Samsung Galaxy mini plus (GT-S5570i) and I want to change the orientation of the lockscreen to be always horizontal. I know that there are multiple apps that can lock it to horizontal. The problem is that after booting and before launcher comes up, the lockscreen is shown for a while and all apps will be activated afterwards. Therefore, I always see the lockscreen in the portrait mode within this period.
I had modified the xml layout of the framework-res.apk and succeeded to change the text inside lockscreen (changing the "swipe to unlock") but changing the layout into horizontal does not work.
Also because it is android 2.3.6 it is not possible to completely disable the lockscreen.
I want to know what and how to modify the framework to make the lockscreen be always horizontal.
