The Samsung Galaxy S III is one of the best selling smartphones to date. As expected, it gets a lot of attention here at XDA due to high interest by both users and developers alike. For those of us who want to fully customize our devices, there are countless custom ROMs like CyanogenMod, AOKP, and Paranoid Android, each with advanced settings built-in that allow us to tweak many aspects of the UI. Though if you want to stick with the default TouchWiz-laden OS shipped with the device and still want to be able to tweak certain UI elements, there’s no shortage of mods for that either. XDA Senior Member gharrington has recently released one such mod that allows you to tweak several aspects of the status bar clock of the stock Galaxy S III firmware to your liking.
The mod adds options in the default Date and Time settings that let you center your clock on the status bar, show or hide AM/PM and the day of the week, or even hide the clock entirely. There is also a (work-in-progress) option to choose the size of the AM/PM display, but it isn’t currently functional and the developer has promised to fix it in an update.
While it is built for the XXELLA firmware, this mod should also work on LKC, LL5 and possibly other firmware versions as well—along with any modified ROMs based on these firmwares. As always, you can find more information and the download link in the forum thread.
