Yesterday the Samsung Gear Manager application got updated to version 2.1.14062401. Unfortuanetly there is no changelog available, which seems like the standard thing, but I do hope that Samsung does get into the habit of releasing changelogs.
Its a bit early for any definite results, but it does seem as if the Gear 2 Smartwatch does seem to be handling battery power and the stability of the bluetooth connection a little bit better. I did previously have a contact synchronisation problem which seems to have been resolved.
If you don't get prompted to update, then go into the Samsung Apps and search for Gear Manager to update. If you do happen to have a changelog, then please use our contact us page to tip us 😉 and please let also let us know in the comments of your findings.
