[Xperia Play Android Development] CosmicDan:
Development suspended until (if) CM10 gets to a faster and stable state. If you want a fast, fully working new MIUI experience, check out my other ROM.

​

Here is an alpha release of MIUI4.1 based on CM10 for the Xperia Play. It is built upon CM10-FXP137 and MIUI Jellybean for the Nexus S.

I am using this ROM as a daily driver now and it seems to be very stable. But since CM10 is still alpha, there may be some bugs still. Future updates may also require a factory reset, so be aware of that.

A CDMA version will come soon, as soon as CM10 is confirmed working on R800x I will work on it for MIUI.

Make sure you read the blue section "Special Notes/Partially working" below before using! It contains very important existing issues and work-arounds.

Working (tested):

Calls / Text / 3G / Data

Audio

Wifi

Camera

ALS / Auto-brightness

Web Browser (from MIUI 2.8.24)

Google Play Store (fully)

Google Now (no Voice Search)

Music/Gallery/Screenshot feature (Menu+VolDown)

Location/Maps/Compass

Gamepad

Touchpads (On most games, thanks to farenheith)

If you find a game that still doesn't have working touchpads, report it in farenheith's thread. Known games reported still not working:

- Dead Space

Not working:

Torch (unknown issue)

Wifi Tether (CM10 issue)

?

Partially working/special notes:

After call is ended, audio is not routed back to loudspeaker. Sounds will be very quiet! You need to either replug headphones or reboot the phone to fix it... sadly this is a CM10 issue and I can't fix it.

In Notification Panel, the Clear/Options button in top-right corner goes off the screen. Change font-size to "Small" (in Settings > Display) to fix this for now.

Google Play Store might not show installed apps or purchased apps after signing in for the first time. Simply 'Clear Data' for Google Play Store to fix it.

When screen is off, VolUp does nothing and holding either Vol button will only skip music tracks forward

?
