How can I quickly delete ALL texts on an unrooted phone? On a rooted phone, I merely delete /data/data/com.android.providers.telephony/databases/mmssms.db and then reboot.

Is there anything similarly quick that can be done on an unrooted phone?

I have a phone that has upwards of 50k texts and every app is hanging when trying to delete a single conversation.

(Android 6.0.1)
Not near as quick, but SMS Backup &amp; Restore app and other SMS management apps can do this, also many SMS messenger apps can do this as well, but without root you cannot do it manually.
