I recently discovered the slow-motion mode on the camera(I know, took some time), but then I noticed that it records only at 800x450(weird resolution, I know), so in my own mind I was like, maybe the camera .apk in system/app contains the resolution info, and maybe I could change it on the computer.
So I copied the camera app to sdcard, and opened it on pc, and changed the resources.arsc file a bit inside the apk. and copied the .apk back to sdcard(ofcourse I backed up the original file to another folder).
Then I proceeded with deleting the original application, which worked, but what didn't work, was installing the modified application, I copied it into system/app, and restarted the phone, still doesen't allow installing it, then I thought that okay, if it doesen't like my modified apps, then I won't install it, and I'll install the original back, copied the original there, checked permissions to be the same as other apps, and restarted the phone, and still didn't let me install it.
So.. does anyone know a way to install the camera app back, without flashing a new rom?
Running original ROM rooted 4.4.2 i9505.
If anyone can come up with a fix for this, I would be happy.
[Edit]: Seems like I fixed it, I checked permissions again and rebooted again, and sure enough, the camera app was back in app drawer.
My question still remains, can the app be modified by someone not as dumb as me, to record the slow-motion video at higher resolution, like 720p atleast, surely the s4 has enough power to record it at higher resolution.
