The Google Play Store received a silent update today. Version 3.5.16 should find its way to you in the coming days and reportedly fixes a few issues some users were having with 3.5.15 like force closes and/or disappearing purchased apps. I checked my Galaxy Nexus and sure enough it was updated although Gingerbread running devices like the Galaxy S 2 and my brother’s G2X had yet to see the update.
No matter, the app has been pulled by the folks at AndroidPolice and is ready for the download. Just sideload and install like any other app and you’ll be good to go. Enjoy.
