Android Question How to delete all SMS in one shot -no select all option in Android 9

google gives android to phone manufacturers. they do what they want with it. numerous cases mentioned here of manufacturers' not supporting a given feature. there's always a factory reset. then write your own sms app, make it the default and no more concerns about messages.

Only the default SMS app can do it.

You can create a new app and set it to be the default messaging app, delete all messages and then set a "real" one.

Well, that's exactly what I wanted to do but I had no clue !
Couldn't find any example or code snippet.

That is why, I had asked about this in #1 itself.
Probably, I had not conveyed my intention properly.

P.S
I have already tried the deleteSMS example using SMSPlus library of https://www.b4x.com/android/forum/threads/smsplus-libinclude-delete-sms.19380/
The deleteSMS function seems to return TRUE always, irrespective of the ID that is passed to it. It doesn't seem to delete anything.
The interesting thing is that its READ function works well. It has read all my 1175 messages !

This worked in the past: https://www.b4x.com/android/forum/t...ut-notification-android-4-4.37171/post-227969

Why such an elementary feature is not provided in Android?

I agreed, that does seem odd.

Looked at three different Android phones here, running 7.0, 5.1.1 and 4.2.2 and the default sms app, and all could delete all messages in one stroke using menu commands like "Delete all threads" and "Delete conversations" + "Mark All".

If you post a screen dump of your Android message app main screen and menu, perhaps what is not obvious to us will be obvious to others.

Your phone does have messages to delete, right? Perhaps if there are no messages, then the menu command is not offered.
