As you guys may know, Samsung takes some time to update its devices to the latest version of Android but always delivers the most stable and bug free build after a ton of R&D. It’s rumoured that Samsung will be releasing the Android 4.3 update for the Galaxy S4 sometime in October/November but we didn’t wanted you guys to wait that long, so we obtained a test firmware for all you Samsung fans out there.

Also, since HTC released Android 4.3 for the Developer Edition One, we just had to give some Android 4.3 love to the Galaxy S4 (GT-I9505) users. We would like to thank our insider because without our insider’s help we would not have been able to provide you folks with this firmware.



We have been testing this Android 4.3 test firmware since a few days now and can say that it’s really stable and the performance has received a significant boost, it’s much faster and lag free than Android 4.2.2. Samsung Knox and Samsung Wallet are present in this test firmware, Samsung Knox works like a charm but Samsung Wallet can’t be downloaded from Samsung servers at the moment. Also, there is a new Reading Mode which optimises the screen for reading, but only a few specific applications are able to use this feature, and there is a new improved keyboard as well. Most of the changes are under the hood, except a few minor UI changes here and there. Now the most interesting part, this firmware has improved colour reproduction of the display quite a bit and the text looks even sharper than before.

Keep in mind that Android 4.3 update is still under heavy development and Samsung may add more features before rolling out the official update itself.
