how do i export text msgs and contacts to laptop
If the contacts on your phone are being synced to your Google account, they’re already available to you from a computer. Just point your web browser of choice at contacts.google.com. Otherwise, I’ve used this app to back up phone contacts: MCBackup - My Contacts Backup - Android Apps on Google Play.
For backing up text messages, I like this app: SMS Backup & Restore - Android Apps on Google Play. The backup file may be sent to cloud storage (Dropbox, Google Drive) and from there transferred to a computer. Alternatively, you may email yourself the backup file as an attachment.
if contacts are sync with Google account you can access them online here
(an export is under the more in the side bar)
