Samsung's mobile phones, including Note 3 and S5, have been upgraded to 4.4.2 system without any news of system upgrade. However, a recent Samsung system upgrade roadmap shows a total of 13 mobile phones upgrading KTU84P (that is, Android 4.4.4), of which S5 and Note 3 have been completed and are expected to be pushed this month.

Other devices mentioned in this table include S4, Note 3 Neo and Note 2, which is quite old, and is expected to be pushed in November. In this table, no S3 is found in the same period as Note 2, but the date on this table is still October 5. It is not ruled out that more Samsung mobile phones can be added to the list of upgrading 4.4.4.

As for Android L, Samsung may not take action until Google releases its official version.
