在Android系统中探索时，我发现了一个有趣的设置，位于运营商配置管理器中：一个标志（KEY_INFLATE_SIGNAL_STRENGTH_BOOL），用于始终向用户报告比实际信号强度高一格的信号。这个设置在Android文档中没有说明，但存在于源代码中，任何运营商都可以使用。值得注意的是，AT&T和Verizon已经在他们的网络上启用了这个标志。我不确定是谁要求将其添加到Android中的，也无法在git历史记录中找到相关信息，但我们可以在每个运营商的CarrierConfig中看到它，其中包含所有网络设置。运营商总是声称拥有最大的覆盖范围或最好的网络，但这种做法，以及虚假的5G标志，无助于建立信任，特别是考虑到神奇的手机天线，使得所有这些欺骗行为都变得不必要。

Poking around in Android the other day I found this nugget in Carrier Config manager; a flag (KEY_INFLATE_SIGNAL_STRENGTH_BOOL) to always report the signal strength to the user as one bar higher than it really is.

It’s not documented in the Android docs, but it’s there in the source available for any operator to use.

Notably both AT&T and Verizon have this flag enabled on their networks, I’m not sure who was responsible for requesting this to be added to Android, nor could I find it in the git-blame, but we can see it in the CarrierConfig which contains all the network settings for each of these operators.

Operators are always claiming to have the biggest coverage or the best network, but stuff like this, along with the fake 5G flags, don’t help build trust, especially considering the magic mobile phone antennas which negate the need for all this deception anyway.
