ICS Power Management

Moving to ICS on the Samsung SII has been underwhelming for the most part - partly driven by the fact that the UI has been kept relatively stale by Samsung, and made worse by the fact that ICS while powerful, has more than a few hiccups during operation.

But there is one aspect that ICS is really good with - memory management. ICS comes with a Honeycomb inspired task switcher that also doubles as a task killer. Flicking an application in the task switcher kills it, releasing the memory and plausibly making battery usage better.

Well at least that was the theory, till I tried to put it in practice and presto - it worked! Check out the screenshot showing a run time of a day and eight hours with more than 40% of the juice still to go. Yes, the usage was not as heavy as I normally do with the phone, but still a 32 hour run time was not something I had frankly expected.

Finally - ICS for Galaxy S2

AT&T had been hinting at the Ice Cream Sandwich upgrade to the Samsung galaxy SII for a while now. Last week it even went so far as releasing the update and then rolling it back after some customers were able to get it.

Looks like whatever kinks Samsung had in producing a custom version for the US market seems to have been taken care of and my phone is now running ICS. Here is a screenshot.

The upgrade process itself was smooth - took all of about five minutes once the backups and such were completed. The only nit-pick, was that you had to install Samsung Kies to actual do the update instead of doing it over the air (OTA). But considering this was a major version upgrade, I did appreciate the backup opportunity Kies presented.

First impressions - not that many actually. Because the version of ICS is a Samsung customized, AT&T pre-loaded version, it is not that different from the Gingerbread copy. But, just beneath the surface there are differences. The biggest being the smoothness with which the interface seems to be working. And of course the subtle UI elements, like in the settings menu. It seems like someone actually spent time thinking about the end user while putting these together.

More details later, but for now, screenshots of the upgrade itself.

Camera speed on Android

Check out the photograph above. This was taken while traveling in a car. Of particular focus are the lines on the road - they are actually straight, but show up as curved in the photograph.

When cameras were first added to cell phones, they were small, slow and blurry. The sensors were tiny, the lenses were basically plastic and the processors were slow. While the megapixel count has gone up, the optics have gotten better, the biggest bottleneck still remains the processing speed.

At least the Android platform has taken an interesting approach to overcoming this processing speed bottleneck. It seems the sensor is read in sequence, line by line, starting from the top. The advantage with the approach is obvious - the camera can process one line at a time, keeping the picture sharp and well processed.

The side effect is the effect showing up in the picture above. The straight lines on the road, show up as curved because the car moved in the time between when the first line of the sensor was read and the last.

Impulse Purchase

At long last, my Nokia 5800 has been retired from active service.

It has been replaced by my new Samsung Galaxy SII. And all this happened within a matter of a few hours.

I had been eyeing an Android phone for a while now. My first choice would have been the vanilla Nexus series - but they tend to be far too pricey and missing carrier specific frequency capabilities on their wireless chipsets. The next choice was the Galaxy series from Samsung. And that is when I saw this deal from RadioShack:

While this was about $50 more than the Black Friday deal from Radioshack, it was still a full $100 less than the discounted price on AT&T's website. And it hit my key checklist items.

• A tried and tested phone chassis - the Galaxy S II is the second in the highly successful Galaxy series.
• Minimal UI customization - unlike the HTC Sense UI, TouchWiz UI is relatively lightweight and optimized for speed.
• A known upgrade path to Ice Cream Sandwich.
• No known carrier hindrances to phone capabilities.
• Speed and responsiveness.

The Galaxy SII hit all points on the checklist - making the decision to switch surprisingly quick and painless. And RadioShack was not that bad an experience, as far as the tactical switch went. On a side note, I need to remind myself that RadioShack is probably a better option for buying electronics when I want something outside the standard mainstream products.

RIP: my ageing Nokia 5800 - you were a trailblazer, and were better than you had any reason to be. Yet, the trail was left cold after you, for no fault of yours. You will be missed.
