Android 4 (aka Ice Cream Sandwich) update issues for Nexus S devices

Wednesday, December 21st, 2011 | Gene Teo | Comments Off on Android 4 (aka Ice Cream Sandwich) update issues for Nexus S devices

Recently Google started updating Nexus S smartphones to Android 4.0.

There are reports circulating that Google is occasionally pausing the update process while they monitor progress and feedback. If you are affected by a pause, when you go to Settings > About > System Updates you will be told “Your system is up to date”, even if you’re not on Android 4.0.

If you were able to download the update, click the “Reboot and Install” button, and then see “Your system is up to date” (when again, the update to Android 4.0 hasn’t happened), this is apparently a different problem – see the picture below, and that’s pretty much all the information we have at the moment.

From the Google Mobile Help Forum

Updating millions of phones is hard, and there are a lot of slightly miffed outraged people out there wanting this update. If you haven’t been able to update, just wait until any bugs have been fixed, and the update process resumes. You will get a more reliable patch as a result.

In the interim, prepare for the update by backing up any important files from the USB storage area of your phone. Just connect your phone to your computer via USB cable – it will show the file storage area just like a USB drive.

To get the best upgrade experience many will factory reset their phones just before or just after the upgrade. You can backup your application data, WiFi passwords, and other settings to Google servers so they can be easily restored after a factory reset. On your Android 2.x phone go to Settings > Privacy > Back up my data

Samsung Galaxy Devices to get Android 4 (aka Ice Cream Sandwich) in Q1 2012

Update 9 Mar 2012 – it begins!

Hot on the heels of Google releasing an upgrade to Android 4 for the Nexus S, Samsung has announced that their Galaxy product line will get their Ice Cream Sandwich (ICS) upgrade in the first quarter of 2012.

The products that will get the upgrade are:

  • Samsung Galaxy S2 (sometimes written as “Galaxy S II”)
  • Samsung Galaxy S2 LTE
  • Samsung Galaxy Note
  • Samsung Galaxy R
  • Samsung Galaxy Tab 10.1
  • Samsung Galaxy Tab 8.9
  • Samsung Galaxy Tab 7.7
  • Samsung Galaxy Tab 7.0 Plus

Of course, it’s the Galaxy S2 owners who will be most excited – and there are many of them! In New Zealand, Samsung has a 28% share of the smartphone market, compared to 13% for Apple. In contrast, Apple has the tablet market all sewn up with 79% market share, vs. 15% for Android.

Sadly it seems that owners of the still-excellent Galaxy S (the predecessor to the Galaxy S2, released in March 2010) will miss out on an upgrade to Android 4/ICS – it’s not mentioned at all in the announcement.

The end of Internet Explorer 6

IE6 market share as of November 30 2011 from www.ie6countdown.com

Internet Explorer version 6 (IE6) was first released with Windows XP in 2001. A decade later, around 8% of computers connecting to the internet are still using it. This is a problem because old software is a security risk, and in the case of IE6 creates an additional workload for web developers, who have to take extra steps to make sure their website works with an old browser.

However, the end is near. Some days ago Microsoft announced that starting in early 2012, they will start automatically upgrading IE6 to the most recent version supported on the computer being upgraded. The goal is to reduce IE6 usage to less than 1% globally.

If you are still using IE6, make plans to upgrade as soon as possible. Old software does not “wear out”, but it does become obsolete. And because outdated software makes it easier for an attacker to take over the computer it’s installed on, using it contributes to internet crime and malware transmission.

Screenshot of the Twitter post with the update news

Over the weeked Google announced via twitter that the next version of Android (version 4) is being deployed to Nexus S smartphones. Android 4.0 (codenamed “Ice Cream Sandwich”) has some design changes, and makes better use of swiping to interact with apps and notifications. See the excellent Wikipedia article for a more comprehensive list of features. Also, there is now built-in support for taking screenshots – press Power and Volume (Down) at the same time to automatically save one.

Reviews of Ice Cream Sandwich are generally very positive. If you have a Nexus S, just go to Settings > About > System Updates to get started. It is about a 130MB download, so make sure you’ve got a good WiFi connection before starting.

Privacy Monitor

The Information Security Office is dreaming of a White Christmas this year.

Especially now that we have a Privacy Monitor …

Following on from the post on Instructables.com that showed how to hack an old LCD monitor by removing the polarised film and re-inserting it into a pair of glasses (http://www.instructables.com/id/Privacy-monitor-made-from-an-old-LCD-Monitor/) we did pretty much the same thing to create our Christmas Decorations this year :-
