For $\varphi:< S > \times X\to X$ and home. $h:X\to X$, what is size $d(\varphi(s,x), \psi(s, x))$? $\psi$ generated by $h\circ \varphi_s$?

Let $\varphi:G\times X\to X$ be a continuous action of finitely generated group $G=\langle S \rangle$ on compact metric space $X$. Also, assume that $h:X\to X$ be a homeomorphism with $d(h(x), x)<\delta$ for all $x\in X$.

Assume that $\psi:G\times X\to X$ is generated by $h\circ \varphi_s$ for all $s\in S$.

Q1. What can say about the size $d(\psi(s, x), \varphi(s, x))$ for all $x\in X$?

Q2. Is it true $\psi(s, x)= h\circ \varphi_s(x)$? If it is true, what can say about equality $\psi(s_0s_1, x)= \psi(s_0, \psi(s_1, x))$?

Note that $\psi(s_0, \psi(s_1, x))= h\circ\varphi_{s_0}\circ h\circ\varphi_{s_1}(x))$
