The Xperia S from Sony is the first dual-core phone from the company. The handset packs in a stellar 4.3-inch screen with 720p resolution, a brilliant 12MP camera, and a stale version of Android…Gingerbread. Sony has promised that it will update the Xperia S to Ice Cream Sandwich sometime in Q2 of this year, after it updates its 2011 line-up of Xperia handsets to Ice Cream Sandwich.

Even though the Xperia S runs on Gingerbread, it comes with an updated version of Sony’s Mediascape UI/UX, which includes a new dialer app with Smart dialing and an updated Music player. The new Music Player comes with an updated UI, Equalizer support, integrated support for SenseME (Sony’s own SoundHound/Shazam alternative), MP3 tagger, a new widget, and much more.

At the moment it is unknown whether this new music player will be included in the Ice Cream Sandwich update for the Arc, Arc S and other Xperia handsets. Until then, an XDA member, datagubben, has managed to get the Xperia S music player to work on the Arc and Arc S running the official Android 2.3.4 firmware.

Below is a step-by-step guide on how you can install the Xperia S Music player on your Arc or Arc S running Android 2.3.4 -:

You need to have root access along with CWM Recovery installed

Step 1) Download this zip file. Extract the contents of the zip file inside a new folder and transfer it to your Arc/Arc S memory card.

Step 2) Install the APK files with the following names – ‘MusicWidget.apk’, ‘SemcMusic.apk’, and ‘Soundenhancement.apk’.

Step 3) Reboot your phone in Recovery mode and install the ‘Soundfx_Xperia_S.zip’ file. Restart your phone after flashing the zip file.

Step 4) Now copy the ‘FBMusicLike.apk’, ‘SemcdataMetaCleanup.apk’ and ‘AudioEffectService.apk’ into /system/app. Also, edit the permissions of these files to rw-r–r–. You can edit the permissions by long pressing the files, and then selecting the Permissions option.

Step 5) Uncheck and then re-check the ‘Facebook Inside Xperia’ and restart your phone after this.

Bingo! You are done! You can now enjoy the Xperia S music player on your Xperia Arc/Arc S! Head over to this thread on XDA forums and thank ‘datagubben’ if you want to appreciate his hard work.
