After Windows Phone release the path of NoDo update to brought copy and paste function on WP 7 phones, it took about 3 months to roll out to all WP 7 devices. Recently, Fuzilla written an article to call Google accelerate the speed of Android 4 updating.
Since then only one device with original Android 4.0 � Samsung Galaxy Nexus released, the only one another device � Nexus S received the update.
Google announced ICS Android 4.0 Ice Cream Sandwich a couple of months back, and so far it has managed to ship a single device with this new OS, the Galaxy Nexus. The second device to get an ICS 4.0 update was the old Google Nexus S, but OTA updates for the Nexus have been suspended due to technical issues. There is still no third device with ICS on board and we won�t see any for at least a few weeks.
Companies are now announcing their own ICS upgrade schedules. LG says that their top devices get ICS in Q2 2012 (April 1 to June 30), while others will have to wait a few more months. Sony Ericsson should have ICS around Q2, if not earlier. Motorola and Samsung are reportedly scheduled to start updating their devices in Q1, but the process will inevitably drag on well into Q2. Worse, Samsung won�t roll out an ICS update for the Galaxy S, which sold in record numbers last year and it�s still a pretty nice phone with an affordable price tag.
In best case scenario, we might see some Android 2.3 to 4.0 update in Q1 but the best chance is to see some new phones launching with Ice Cream Sandwich at the Mobile World Conference, in Barcelona in last days of February.
Apple has IOS 5 in all of its phones capable of supporting the new OS for months now and at least the top two iPhones today, if not the top three, will get an update to the next version, guaranteed. Microsoft is also doing a pretty good job in the update department with Mango.
By the time LG and Samsung roll out updates for the Optimus 2X, the world�s first dual-core phone and the best selling Samsung Galaxy 2 phones, Optimus 3 should be launching as well as Samsung Galaxy S III. In some countries, LG rolled Android 2.3 just a month ago and by that time, Google already announced and showed Android 4.0.
But there are different devices with Android system in different mobile phone brands. The time is really so hard to control.
