The Samsung Z3 (model SM-Z300H) has just received its next Maintenance Release firmware update, taking it to version Z300HDDU0BOL4 for users in India. This update is only 3.6MB, which some might consider not worth updating, but any improvement is a worthwhile improvement I say.

The previous Indian firmware update Z300HDDU0BOL2, which was released 3 weeks ago, was also quite small at 41.4MB, but this is tiny 🙂 There is no changelog and nothing obvious I can see this update bringing us, so most likely for performance and big-fixes.
