Thoughts on Android 2.3.5 for the Galaxy S

As I mentioned before, I’ve been using for some time now the Android 2.3.5 update for the Samsung Galaxy S and it deserves some comments.

Good news first:

– The previously reported Android OS battery drain bug is apparently gone! This just means the phone does not drain the battery all by itself in a dozen hours or so, which was a huge problem. The Android OS process is now at a more reasonable 6% share of the overall battery consumption.

– The browser scroll now works properly as in any other smartphone in the market

Unfortunately, there’s a few problems with this firmware:

– As I said in the previous blog post, the TouchWiz launcher crashes randomly.

– The phone process is also crashing a lot, especially soon after the end of a phone call, as you can see in the picture below.

– The browser may now present a correct scroll behavior but the stability is worst than before, which is not good because the browser was never the most stable app in Android.

It wouldn’t be so bad if it did compensate the lack of stability with improved performance, but running the SunSpider javascript benchmark returned a result of 6505.1 ms which is a regression compared against the 6305.4 ms scored by Android 2.3.3.

Apparently stock browser javascript performance optimization is not a priority for Samsung, neither is improving the stability of the official firmwares they release for the Galaxy S.
