Averaging is the right algorithm. The tradeoff is averaging lots of
readings makes the movement smoother but slower to respond (lag). try
averaging 8,16,32,64 samples. When it gets too slow, back up one.

In addition to averaging.
You can also investigate tresholding.
Display your icons and don't move them unless there is a minimum
amount of displacement. You'll need fine tuning here, it will
compensate for small movement of the hand while looking through the
phone.
Don't forget parralax in your w

Oh and I forgot,
The other option you have that would be very accurate but requires a
biggest computational and battery overhead : Form recognition.
Using specific points on the image and following them will give you a
much better tracking(after effects style) on small movements.

First of all, thanks everybody for their answers. I've been in
journey, that's the reason because of I haven't answered before. I've
tried average and tresholding, althougt not too much extensively.
Special thanks, Yahel, the parralax is very important. I've seen that

I posted my code in this thread:

That code is for a band pass filter. Refer to the linked article which gives
the formulas for low pass filter as well.
