This is still a problem for me; significant camera jitter on S6 Edge.

This stinks. Unity is not giving us any information on this issue and it is NOT fixed.
Create a scene with some 3D blocks with 1 unit gaps between them. Drop in a camera. Add script to camera that moves the camera using translate. You can do this in Update, LateUpdate, FixedUpdate change Time.xx to fixed, smooth etc. Change the vsync on or off. Set application fps or not. Nothing matters. Build this to an S3, S4 or whatever major android device and guess what jitter, jitter, jitter every few seconds. You notice it mainly if you watch the dead space between the cubes. Ruins the effect of a smooth side scroller.
transform.Translate( ( Vector3.right * 3 ) * Time.deltaTime );

NOT fixed in 4.6.1 for Android builds. Even a most basic example of a few sprites translated with Time.deltaTime in Update will stutter on Android.

That is my experience as well, BLASTERJOKER. Turning vSync on gives me 30 fps on iOS to start with. But after a few seconds I get down to 15 fps or lower. What works best for me is setting targetFramerate to 60 and turning off vSync, but that still stutters...

My experience is that this has not been fixed with unity 4.6.1. Still jittery/ has hiccups for android. Any one else still have this problem?

I tried to set the Quality settings to "Fantastic" and it helped a lot, but still not perfect smooth motion, but much better.

I used a special time smoothing method and it works on iOS. But on Android, this problem persists no matter what.
So far, I have used Transform.localPosition changes in Update, FixedUpdate; lerping in either of them and eventually looked at the 2D Platformer sample and used their other method of rigidBody2D.velocity in FixedUpdate.
Results are notably better in the editor but on Android - there are still perceivable hiccups (not as bad as before). This is for an extremely simple game with less than 10 sprites moving around and being reused. Even on a test project with just 3 sprites, the severity of the issue is the same.
Seen on Galaxy Tab 3 7" and Nexus 7 2013.

Might be related to the same issue described here:
http://forum.unity3d.com/threads/jittery-camera-movement.256420/ and
http://fogbugz.unity3d.com/default.asp?619093_dtpufuedu1bpuv84
The report mentions WebPlayer only but it's noticable on anything where the framerate isn't in the hundreds.
