My reasonably smooth upgrade to Ice Cream Sandwich

Filed under: Android, change, compatibility, Google, Samsung, WordPress — David Wood @ 9:42 pm

I’ve been looking forwards to the new experiences that would be unlocked by installing “Ice Cream Sandwich” (Android 4.0) in my Samsung Galaxy Note, in place of the Gingerbread (Android 2.3) it originally contained. But I’ve been delaying the upgrade.

I’m a big fan of new technology, but my experience teaches me that upgrades often bring disruption as well as progress. Upgrades of complex software systems often unintentionally break functionality, due to unexpected incompatibilities with the old platform. And even when functionality is improved, it can take some time for users to learn a new interface: old habits have to be unlearned, and new “intuitions” acquired. That’s why I’m sometimes a technology laggard, as well as a technology enthusiast.

But today is the day. The new platform is mature, and is no longer “bleeding edge”. It’s been on the market for a few months. Several of my Accenture work colleagues have already upgraded the Galaxy Notes they use, without reporting any issues. And some of the applications I now want to test (applications developed by work colleagues) rely on functionality that is present only in the newer platform – such as improved Bluetooth. So this morning I resolved: let’s do it today.

In summary: the experience was smooth, although not without glitch. So far, I am pleased with the outcome, although I’ve experienced surprises along the way.

The first surprise was that I had to go looking for the upgrade. I had expected I would automatically be notified that a new version was ready. After all, a similar system works fine, to automatically notify me of the availability of new versions of the apps I’ve installed. And – see the following screenshot – my phone had the setting “auto update: check for updates automatically” enabled.

However, my experience was that I had to explicitly press the button “Check for updates”.

That button helpfully recommended me to ensure that I was on a wifi network. Good point.

The update would happen in two stages:

  1. First, the new version of the software would be downloaded – all 349.38MB of it
  2. Second, the new software would be installed, in place of the old.

The download system estimated that it would take 16 minutes to download the new version. It told me I could keep on using the device in the meantime, with the download proceeding in background. Having kicked off the download, and watched the first 10% of it complete fine, I switched tasks and started browsing. In retrospect, that was a mistake.

As the download proceeded, I read some tweets, and followed links in tweets to Internet pages. One link took me into someone’s Google Plus page, and another link from their took me to yet another page. (By this stage, the download was about 60% complete – I was keeping an eye on it via a notification icon in the top bar of the screen.) I then tried pressing the Back button to undo the stack of links. But as sometimes happens, Back didn’t work cleanly. It took me “back” from one page to the same page, with a minor shiggle in between. This kind of thing sometimes happens when a link includes a redirection.

This is where personal habit took over. In such cases, I have fallen into the habit of hammering the Back key several times quickly in succession. And that seemed to work – I ended up back in the Twitter application. But a few minutes later, I realised that the upgrade notifier icon had disappeared. And the download was nowhere to be found. I think that one of the Back buttons must have ended up going to the download window, cancelling it. Woops.

No problem, I thought, I’ll restart the download. It will presumably continue from where it had been interrupted. But alas, no, it started at the beginning again.

The second time, I resisted the temptation to multi-task, and let the download complete in splendid isolation. Around 20 minutes later, the download was complete. I thought to myself, Now for the more interesting part…

Before completing the installation, I ensured the mains power lead was plugged in, to avoid any complications of a battery failure half-way through rewriting the operating system part of the phone. At all costs, I did not want to end up with a “bricked” device (a device that cannot restart, and has as much life as a brick).

The upgrade proceeded. The screen changed several times during the process. At one stage, a progress indicator seemed to become stuck at around 80% complete for ages – so that I wondered if the system had crashed – before finally slowly inching forwards again.

Once the phone restarted, it run through yet more steps of the upgrade. It told me it was “Optimising application 1 of 82” … “Optimising application 82 of 82”. Then it said it was “Upgrading Contacts database” and “Upgrading Agenda database”. Clearly a lot was happening behind the scenes.

Finally it showed the familiar SIM unlock screen. Except that it wasn’t exactly the same SIM unlock screen as before – there were small but noticeable changes in the layout. Likewise with the device unlock: the ‘OK’ button is now in a different position from before. My fingers will need to learn a slightly different physical sequence, to unlock the device.

A bigger surprise was that all my customisations to the seven different home screens were lost – they had all been reset to defaults. It’s no big deal – I can gradually change the screens back to what I personally find convenient. And a good clean out is probably not a bad idea.

There are lots of pleasant surprises too. For example, there’s a handy new “Restart” addition to the dialog that is shown when the power switch is held down:

Here’s another example of an unexpected change: I found by trial and error that screenshots are now stored in a different directory on the phone – \phone\pictures\screenshots rather than \phone\screencapture – and are (it seems) stored in a different way: they’re not written to disk until some indeterminate time after the screen capture has finished.

That change caught me out twice over: first, because I could not find the screenshots (as copied into this blogpost) in the place I was accustomed to finding them, and second, because the files I tried to upload into WordPress were zero bytes in size. (WordPress helpfully advised me to “upload something more substantial”.)

In case this sounds like a litany of complaints, let me hasten to clarify that I find the entire process highly impressive. A huge quantity of software has been transferred wirelessly onto my phone, including countless changes from before. It’s a technology miracle.

What’s more, I didn’t pay anything for this upgrade. It’s a free technology miracle.

But I am glad I waited until the weekend before embarking on this upgrade, rather than trying to squeeze it into the middle of a busy work schedule. Significant change deserves significant time.

  1. Good to hear this worked. I’m still waiting for my chance to upgrade , not until December :-(. I was slightly put off the ‘Note’ as I was told it only shipped today with Android 3.2, whereas the Galaxy SIII ships with Ice Cream Sandwich. Still got my eye on the Galaxy Nexus Tablet in the meantime.

    • >I was told it only shipped today with Android 3.2

      Android 3.x is only for tablets, not smartphones – and not for the Note either. It shipped with Android 2.3, aka Gingerbread. See also http://en.wikipedia.org/wiki/Android_version_history

      >I was slightly put off the ‘Note’…

      I wish I could say, “Look at my example, it’s relatively easy to upgrade, therefore you would have the same experience”. But it all depends on whether the Note you would buy would have lots of operator customisation. In that case, there may not be an upgrade available. Operator customisation significantly complicates the upgrade path, as the customisations all need re-merging and re-testing. In my case, I had a vanilla Note, without any operator customisation. (I bought it without any operator contract.)

      >Still got my eye on the Galaxy Nexus Tablet in the meantime

      Agreed, that looks like an interesting device. The rumoured forthcoming “Note 2” has my attention too – see e.g. http://www.t3.com/news/samsung-galaxy-note-2-release
