H5 page adapts, why does Android have a bigger screen and a smaller page?

the flexible.js, design draft is 750px, which displays normally on 6 and 7p. On Android, you will find that the page has become very small. 

<head>
    <script src="http://g.tbcdn.cn/mtb/lib-flexible/0.3.4/??flexible_css.js,flexible.js"></script>
    <meta charset="utf-8">
    <meta content="yes" name="apple-mobile-web-app-capable">
        <meta content="yes" name="apple-touch-fullscreen">
        <meta content="telephone=no,email=no" name="format-detection">
    <title></title>
    <script src="http://libs.baidu.com/jquery/2.1.1/jquery.min.js"></script>
    <script type="text/javascript" src="index.js"></script>
    <link rel="stylesheet" href="index.css">
  </head>

the plug-in on this side of ide sets 1remmemor75px, which should not be a problem. Ask God to save the child

Javascript css html
Nov.29,2021

as far as the current code is concerned, it is obvious that viewport is not written in the meta tag

just tested why I use the same

as you do.
http://g.tbcdn.cn/mtb/lib-flexible/0.3.4/??flexible_css.js,flexible.js

but did not generate

viewport content= "initial-scale=0.5, maximum-scale=0.5, minimum-scale=0.5, user-scalable=no"

tested and found that this seems to be a bit of a problem in the case of a slightly larger ipad (remember that the maximum width was 750, but now there seems to be no such limit).

you can try this

! function (eMagnet) {function n () {t.bodyroomt.body.style.fontSizeroom12roomo+ "px": t.addEventListener ("DOMContentLoaded", n)} function d () {var estrangi.clientWidthpac10 px. FontSizeSecrete+ "px"} var iDevicePixelRatio | | 1; If (n (), d (), e.addEventListener ("resize", d), e.addEventListener ("pageshow", function (e) {e.persisted&&d ()}), o > = 2) {var a=t.createElement ("body"), s=t.createElement ("div"); s.style.border = ".5px solid transparent", a.appendChild (s), i.appendChild (a), 1=s.offsetHeight&&i.classList.add ("hairlines"), i.removeChild (a)}} (window,document)

Update: I just saw that the official document has advised you to give up the scheme you are using. Replaced by https://github.com/amfe/lib-f.
