I have a HTC vivid and need to delete about 30,000 texts. Every time I try to do it, it freezes my phone. The same thing happens when I try to create a backup.
There is a way to delete all SMS and MMS (and call logs) all at once.
In Android, SMS are normally received and stored by the package com.android.providers.telephony. That package’s common name is “Phone/Messaging Storage” in Android 4.2.2 and “Dialer Storage” in Android 2.3.7.
If you clear all data of that app, all it’s databases are cleared and SMS/MMS are gone. You can “force stop” and then “clear data” with the app manager, which you find under
- Settings→Application settings→Manage applications
If you have an alternative SMS app, note that most of them side access the “standard” database anyway. – This is technically not clean, but has the huge advantage that you can swap SMS apps at will, because the SMS storage stays the same.
Here the step:
- Backup All SMS using "SMS Backup & Restore" app to your externalCard
- Your devices must be rooted
- Open root explorer, go to /data/data/com.android.providers.telephony/databeses/mmssms.db
- if you want you can copy the current "mmssms.db" to externalCard for backup too
- Delete current "mmssms.db" file
- Restart phone
- Now all your sms will disappear, if you want restore just some of sms threads, you can restore them using "SMS Backup & Restore" app from the backup sms data that already made
Hope this help
You might also try using a phone manager via your PC that works over Wifi, such as AirDroid. You should be able to delete from there, but not all of them at once I don't think, but in batches at least...
If a factory reset isn't acceptable, you might try an app such as Handcent, which allows you to set a limit on how many messages are kept for each sender. Set the limit to 29000 and see if it trims them down in a reasonable time. If that works, try dropping the limit 2000 at a time until you get to the number you want. This won't work if your messages are from many different senders.
