The promised June jump to the latest Android version of former Samsung flagships Galaxy S3 and Galaxy will likely suffer a disappointing pushback no thanks to the new TouchWiz version, a new report said.

The likelihood is the GS3 and the Note will not chew in Jelly Bean 4.2.2 anytime soon and millions of owners of these Samsung smartphones can pin the blame on the Asian tech giant's Android-based skin, SamMobile said in a report.

Note that TouchWiz was expectedly upgraded by Samsung engineers when the Galaxy S4 was unveiled earlier this year, incorporating new Premium Suite offerings and sensor-driven Smart features.

The same bump ups, however, will mean that more re-coding are required to ensure that Jelly Bean 4.2.2 will work without glitches with TouchWiz. That translates to additional waiting months for the official Android-Samsung file updates to hit the millions of active GS3 and Note 2 worldwide.

Officially, the two flagships still run on Jelly Bean 4.1 many months after their respective release dates last year. And they will have to wait further as SamMobile insisted that the 4.2 treatment for these handsets will not arrive in the next few months.

Samsung wants to integrate the new TouchWiz with the latest Jelly Bean, hence the delay, the same report said.

No specific target date was mentioned to the Jelly Bean update deployment but the safest bet is between September and October, Android experts said.

And chances are Google will have dispatched Jelly Bean 4.3 or Android 5.0 (aka Key Lime Pie) over the next few months and many Galaxy smartphones will remain stuck with Jelly Bean 4.2 or earlier versions.

The situation underscored the nagging fragmented updated process of the Android mobile operating system as device manufacturers and telcos struggle to keep up with Google's clockwork update schedule.

This is in direct contrast with Apple's iOS upgrading system, in which iPhones, iPads and iPods in global circulation quickly absorb new software fixes and improvements as soon as they are released.
