Put the u1 firmware on phone last night and then used the Samsung vvm from the note 10 thread around here and kept getting unsupported... when I went into the galaxy store the update was there but kept failing to install. I deleted the one from the note 10 I installed and it updated the preloaded app and now it works.
Do you have the link for the apk? I searched the note 10 forums and cannot find it.
