How to add \subsection{Review} in the form 1.1 Review  instead of a ball like this?

If you just want to show the plain subsection number, you could use the predefined \setbeamertemplate{subsection in toc}[subsections numbered] template.

If you'd prefer the subsection in the same style as the section, you could define your own template:


\documentclass[14pt]{beamer}
\usetheme{Warsaw}

\makeatletter
\setbeamertemplate{subsection in toc}
{\leavevmode\leftskip=6.5ex%
\llap{%
\normalsize%
\begin{pgfpicture}{-1ex}{-0.7ex}{1ex}{1ex}
\pgftext{\beamer@usesphere{section number projected}{tocsphere}}
\pgftext{%
\usebeamerfont*{section number projected}%
\usebeamercolor{section number projected}%
\color{fg!90!bg}%
\inserttocsectionnumber.\inserttocsubsectionnumber}
\end{pgfpicture}%
\kern1.25ex}%
\inserttocsubsection\par
}
\makeatother
