首先感谢一下alexdon的翻译
1&2.我使用的是中国联通的网络，之前使用三星的手机都是可以正常使用这些功能。这明显就是手机厂商适配问题。
3.由于中国的网络无法连接谷歌，也无法使用，谷歌商店以及其他任何服务。所有软件都是从第三方网站或者是系统自带的应用商店下载的。基本上大多数软件都会为了获得推送，把进程挂在后台持续运行。甚至还有些软件会在后台举办狂欢派对，相互唤醒以便消耗电量。即使你开了内存优化以及节电优能的全部优化。把应用程序，都设置为限制后台运行，并且把存在的进程全都删除掉。他们还是会自动启动并在后台运行。主要原因是中国的软件大都不规范，这款手机缺少自启动管理功能。
目前业界普遍的做法就是：过于活跃的程序，将限制自启动，在内存即将占满时将自动删除后台软件进程。偏偏就是索尼移动，他们选择让手机卡顿，死机。好让我们知道他们的系统做的有多么不堪。
4.当时买这台手机主要是因为索尼的手机外观非常独特，没有刘海，屏幕上也没有被打孔。在19年和20年都是非常罕见的。鬼知道买回来会出现乱七八糟的问题。毕竟门店的体验机用起来非常的流畅。每次遇到问题，客服只会要求你恢复系统或者送到维修网点检测，好让他们收取你服务费。至于普通手机缺少的功能，他们总是会这样解释：我们的手机就是这样设计的，没有这项功能。
这款手机在中国的市场过于小众，他们甚至到目前为止都没有为中国版提供软件更新。只能说索尼公司至今都是无所作为，他们根本不在乎消费者。.
Thanks alexdon for the translation first
1 & 2. I'm using China Unicom's network. Previously, Samsung's mobile phones can use these functions normally. This is obviously a problem for mobile phone manufacturers.
3. As the Chinese network cannot connect to Google and cannot be used, Google Store and any other services. All software is downloaded from third-party websites or the application store that comes with the system. Basically, most software hangs processes in the background to get push. There are even softwares that host carnival parties in the background, awakening each other to consume power. Even if you turn on memory optimization as well as all optimizations of the power saving excellent. Set the application to restrict background running, and delete all existing processes. They still start automatically and run in the background. The main reason is that most of China's software is not standardized, and this phone lacks self-starting management function.
The current common practice in the industry is: excessively active programs will restrict self-starting, and background software processes will be automatically deleted when memory is almost full. Just because of Sony Mobile, they chose to let the phone freeze and freeze. Let us know how uncomfortable their system is.
4. At the time, I bought this phone because Sony ’s mobile phone has a very unique appearance, no bangs, and no holes on the screen. It was very rare in 19 and 20 years. The ghost knew that there would be a mess when it was bought back. After all, the store experience machine is very smooth to use. Every time you encounter a problem, the customer service will only ask you to restore the system or send it to a maintenance outlet for testing so that they can charge you for your service. As for the features that ordinary phones lack, they always explain this: our phones are designed like this, without this feature.
This phone is too niche in the Chinese market, and they have not even provided software updates for the Chinese version so far. It can only be said that Sony has done nothing so far, they do not care about consumers at all.
