Hello found that grapheme USB back up doesn't necessarily do 100% job. Any suggestions I am trying to connect USB c on old phone to USB c on new phone and just do tether complete data transfer copy any suggestion on how to do it?

    I haven't tested the Seedvault backups yet, but you regularly hear people in the forum complaining about problems.

    Personally, I am a fan of a clean installation and try to transfer as few settings as possible.

    I would therefore:

    old device:

    • make a short text file (or make screenshots) about user profiles and all settings that deviate from the standard system settings and where you created individual settings of all apps (which permissions are granted, storage scope, etc.)

    • if you can't do this via an account (e.g. Play Store): create a short list of all installed apps

    • if possible / necessary: use the export function of individual apps for the settings that you have spent a lot of time configuring (e.g. podcast-playlist, list of RSS feeds, settings of an laboriously configured third party launcher)

    • create a backup of messenger chats, photos, documents and other personal files and contacts (if only stored locally)
      -

    • keep your old phone alive - for some banking apps or messengers it might make moving things a lot easier if you can confirm the action on the old device

    • Drag the backup to a stick or computer

    new device:

    • fresh, clean reinstallation of GrapheneOS via web installer
    • create desired user profiles
    • if necessary, reproduce your prefered system settings as on the old cell phone (move along the text file or screenshots)
    • reinstall apps and import settings if necessary
    • adjust the permissions and privacy settings for each app
    • transfer files, photos, chat history backups and contacts

    It is of course more time-consuming than an automated backup solution - but my experience (I haven't been with GrapheneOS for that long) with other cell phone manufacturers in the past was that the transfer hardly ever worked as smoothly as promoted and i endend up configuring things.

    And -as a nice side effect - if you go through all the settings and menus again after a fresh installation and think carefully about what you have set and why, you will probably find some things you're glad to adjust or change.
