I recently took my iPhone SE for a battery replacement. As with any other iPhone service, I was asked to backup everything. I did the backup in iCloud which includes everything that the backup allows.
I usually type in my native language using the English QWERTY keyboard, so I use tons of custom words in my every day conversation. 3 years worth of custom words were stored, and upon restoring the device from the backup after the service, POOFFF my words are gone! It is so frustrating that I need to type my custom words all again for auto-completion.
Does iOS really take backup of the custom words?
If not, is there any way to manually save and restore the iOS custom words dictionary?
