Symptoms: Upgrading from 2.4.13 to any later build of MIUI, the voice search/voice transcription function in the google search Widget and Android Keyboard disappear after upgrade. Installing the official Google voice search app from play store does not bring the mic button back to the android keyboard. Source of problem: MIUI 2.4.13 had the apk: Voice Search 3.0.1 all later versions of MIUI no longer have this .apk and can't find it in the official play store to download. Only version available is older google voice search from june 2011 which doesn't have the new ICS type as you dictate function. Temporary Workaround: - Under MIUI 2.4.13 use Titanium backup to backup the Voice Search 3.0.1.apk - Upgrade to latest MIUI version - Check Android Keyboard ((previously "Android keyboard 4.0.4-255454), in latest MIUI build "Android keyboard 4.0.4-2.5.18). Mic button does not appear on keyboard. - Use Titanium backup to restore the Voice Search 3.0.1.apk - Retest keyboard, and mic button now working again. ICS type as you dictate working again.
