我已经将我的Galaxy Note II升级到Android 4.3，如果在编写SMS时打开菜单，则不会有没有计划的消息选项。它在哪里消失了？
I've upgraded my Galaxy Note II to Android 4.3 and if I open the menu when writing an SMS there is no scheduled message option anymore. Where is it gone?
Other users have also reported that this feature has disappeared.
One alternative would be to use SMS Scheduler, or GO SMS Pro (my fave SMS app).
I was upset at this at first. But, because I rely so heavily on scheduling messages and didn't want to clog up my memory with yet another app just so I can schedule messages, I looked harder. The option is actually still available, it's just been moved. The new location makes absolutely no sense, which is probably why everyone thought it had been removed. Here are some screenshots to show how it's done now.
These images show the conversation I have set up with myself to test various message related things. In the images, you can see the final test message is set to delay (indicated by the little clock). That message just went through while posting this, so I can verify it did work. I no longer feel the need to dump Samsung, and hopefully now neither does anyone else. :-)
Check out PVLL. The app lets you schedule texts in the future.
It also has an automatic delay of 5 seconds before sending, called the "5 second rule", so that I can cancel any errant texts that I send.. Works for me. And there's a sharing layer on top of SMS that lets you share your conversations easier. I use it instead of taking screenshots or cut and paste.
