Samsung U.S. has posted the latest highlights and recipients of Android 4.4 KitKat software upgrade. It includes the Galaxy S3 and Galaxy Note 2 among several devices receiving another major update but not every model. The 1GB Galaxy S3 model is rumoured to be an exemption for the update.
The Galaxy S3 was considered future-proof but now its hardware components reached aging point that not all variants of the yesteryear flagship smartphone are receiving Android 4.4 KitKat update.
Sprint enlisted Galaxy S3 as part of the upgrade plans for Android KitKat along with Galaxy Note 2, Galaxy S4 Mini and Galaxy Mega. U.S. variant of Galaxy S3 features 2 GB of RAM which also 4G/LTE capable that makes more sense to update compared to the GT-I9300 model.
Update Window Period
Another reason aside from hardware compatible is the 18-month update window period followed by Samsung. Galaxy S3 GT-I9305 was released back in September 2012 and if you count 18 months, software support expires in March 2014.
Galaxy S3 GT-I9300 was released back in May 2012 and already reached its expiration for any further upgrade plans. Owners of the I9300 model will have to upgrade to S4 or stick with Android 4.3 Jelly Bean forever unless custom ROMs are used to update it.
Contrast with Galaxy Note 2
It sounds discriminating on part of Galaxy S3 I9300 users not having Android KitKat update but Galaxy Note 2 backs up the update window period for that model. Galaxy Note 2 was released around the time as with Galaxy S3 GT-I9305 and remains eligible to get another major update in April even though the software support already expired this month which will be its final firmware upgrade.
