我最近开始接收与"@" 字符结尾的大量消息。我问为什么他们说他们不这样做。我们都使用Android，都使用Textra，我也在其他短信应用中检查，我的末端仍然有"@" 符号。它不是每个消息，只需随机。什么可能导致这个错误？
I recently started receiving a lot of messages ending with the "@" character. I asked why and they said they weren't doing that. We both use android, both use Textra, and I checked in other SMS apps too and there were still "@" symbols on my end. Its not every message either, just random ones. What could possibly cause this bug?
