把2G和3G信号调大两格或满格

春风不识路发表于 2023-04-29 11:50 894

之前git log看过去除4G通话以及去除2G、3G还有4G信号的问题，目前对信号的需求做的比较少，刚好今天做了一个调大信号格数的问题，其实信号强度还是不变的，只是让使用者看起来信号变好了，信号格数变多了（黑心的厂家），下面看修改方法; 在8321_git_13\alps_mssi\frameworks\base\telephony\java\android\telephony路径下有下面几个文件，分别是2G、3G还有4G 图片描述这几个文件代表的分别是： CellSignalStrengthGsm.java是2G信号 CellSignalStrengthCdma.java里面是使用CDMA2000通信技术标准的3G信号 CellSignalStrengthTdscdma.java里面是使用TD-SCDMA通信技术标准的3G信号 CellSignalStrengthWcdma.java里面是使用WCDMA通信技术标准的3G信号 CellSignalStrengthLte.java是4G信号代码修改如下：

这里面的值范围改的越大，信号显示的格数就越满（实际上信号强度没变，都是骗人的），mssi路径是Android13，mtk对自己的代码和谷歌分开了，但是framework不影响，此方法应该是11到13通用的
