§ Moving apps to the storage card doesn't back up the apps. If you
do a factory reset, your phone loses the apps. You'll need to
reinstall them.
§ When you remove the storage card and insert it in another phone,
the apps on the storage card won't be installed automatically to
the other phone. You'll need to reinstall them.
Messages Back up your text messages to the phone storage or storage
card, or save them as an email attachment.
Contacts § Save contacts and other personal data to your online
accounts so you can just sync them when switching to
another phone.
§ If you have locally stored contacts in the People app,
export them to the phone storage or storage card.
Files Manually copy and paste files by connecting HTC Desire 612
to your computer as a disk drive.
Other data § If you added new words to your personal dictionary in the
onscreen keyboard, back up the dictionary to the storage
card or save it as an email attachment.
