Cause of move twitching on Unity3D?

Question

Android

I have been suffering with a problem for a long time, when I move an object, it twitches intermittently, in small jerks. Found several people with the same problem and no result.
Game 2D, Android
Tried: change Vsync; put physics; use different properties Time.deltaTime\smooth and remove them altogether; tried Dotween; tried on other computers, on other mobile devices; tried both FixedUpdate and Update; I tried Lerp, doing it on coroutines, etc.
Tried on different computers and devices. Tried on an empty project with regular cubes. I also rolled back to version 4.6, everything also twitches.
And the result is still the same. Periodically twitches

transform.Translate(Vector2.right * Time.deltaTime * speed);

Answer 1

I had a similar "sub-pixel" twitching. When the frame size was several times smaller than the screen size and increased with input. At the same time, the camera movements did not occur by an integer number of pixels and were rounded in one direction or the other during rendering. And after the scale, it was already twitching by several pixels, and not by one, and it was very noticeable. "Repaired" by rounding the camera coordinates to whole pixels.
I don't know if this is your problem, but it might help.

Answer 2

remove it, and there will be no sharp movements
