Why we cant get upgrade of jelly bean on Sony Xperia sola And Sony Xperia U ?


               Sony confirms to give Jelly bean upgrade to Xperia T, Xperia TX and Xperia V during February and March. Also Xperia P, Xperia J and Xperia go will be upgraded from the end of March. but Unfortunately Xperia arc S, U, sola, miro and tipo are upgraded beyond Ice cream sandwitch.
               When we se sony xperia J it is single core 1 Ghz processor power by Adreno 200 Gpu And 512MB. The Sony Ericsson Xperia Arc Also 512MB ram and more powerful Adreno 205 Gpu which is more Powerful Adreno 200. Sony Xperia sola and Sony Xperia U have More Powerful Dual-core 1 GHz Cortex-A9 and more Powerful Mali-400 than Adreno 200 And same Amount of ram(512MB).

              So Reason for not upgrade is The More powerful Gpu at lower amount of Ram. how can 512MB ram is less in Xperia arc S, U, sola and not inXperia J.

             The dedicated Gpu,s in mobile allocate some amount of Ram as a graphics memory. The lower Adreno 200 only allocate about 100MB memory out 512MB so remaining 400MB+ goes to run Android OS.  If Jelly take about 200MB to 250MBto Run on xperia J their is plenty Ram available to run 150MB to 200MBto run apps to Smoothly like a butter.

             The dedicated Gpu's of Xperia arc S, U is Mali 400 or Adreno205 which are more powerful than adreno 200. Since Power of Mali 400 or Adreno205 required better amount of graphics memory than adreno 200 to run good gpu performance on phone. The Mali 400 or Adreno205 allocates about 150MB to 200MB or even more also since we remain with 300MB+ memory. If sony launches jelly bean update on this it take about 200MB to 250MB the phone gets only about to 50MB to 100MB which is less to run multiple apps if we run 2 to 3 apps the phone starts to hang.  On Ice cream sandwitch os uses less ram than jelly bean about 100MB to 150MB we got plenty of ram about 150MB to 200MB to Run more apps than jelly bean. People get more problem by upgrade while running multiple apps at same time such music listening , facebook, sync, downloading etc. The Xperia arc S, U loss their butter smooth interface while running multiple apps due to lower memory. People get in trouble due upgrade and not get satisfaction like Ice cream sandwitch on Jelly bean.So decided  to Keep on ICS.

        The Xperia  miro has Xperia tipo and tipo dual Same Ram 512MB And Adreno200. Here the main problem is processor which is 800 MHz Cortex-A5 processor which is lesser by 200MHz by Xperia j's 1GHz Cortex-A5 processor. Their is no problem of ram in sony tipo, tipo dual and miro but poor processor performance make them fall back. Even with 800 MHz Cortex-A5 processor their is no problem in running Jelly bean sony must concern that beacause Samsung Galaxy mini 2 has same ram(512MB) Same 800 MHz Cortex-A5 processor and Adreno 200 Gpu
they launched upgrade of Jelly bean to this phone.
