After updating my Samsung Galaxy SII to Jelly Bean a couple of weeks ago, Samsung pushed even newer firmware (I9100XWLSD) to my phone which is the best of all official Samsung ROM’s to date: with the update JuiceDefender was able to squeeze over 50 hours out of my Samsung Galaxy S II battery:
Last week I flashed my Samsung Galaxy S II with the official Android 4 firmware from Samsung. Here’s some information and semi-random thoughts about the upgrade and my Ice Cream Sandwich on Samsung-experience so far.
About the upgrade:
I didn’t use KIES, the official Samsung upgrade utility as it claimed there was no upgrade.
More interesting, from a security point of view, are “encrypt device” and “encrypt SD card”. Should give that a try.
The data usage app is really great, allowing you to monitor and manage data usage for the entire device and on a per-app basis. “Data Usage” is, as far as I’m concerned, one of the hidden treasures in ICS!
I rooted the phone with CF-root to be able to install SetCPU.
SetCPU, which I had previously used on my HTC, seemed to work all right at first, but it sometimes put my phone into a deep sleep during phone calls or when idle, with nothing but a forced reboot to wake it up. I uninstalled SetCPU (and am still looking for a similar tool to save battery mainly).
I also installed AdFree Android, which adds known ad-domains to your hosts-file, having them point to localhost. Only for rooted phones, but it works like a charm. More privacy and better battery-life will be yours!
