Some Android users have noticed an updated version of the Google Play Store has started to roll out today. The update takes the Play Store up to version 4.1.10. The previous version that was publicly rolled out, and which most people probably have installed, was 4.1.6. With such a small increment in the version number, this is likely just some bug fixes. Some early reports indicate it may address some location issues and some text layout problems.
If you want to give it a try, you can download the .apk using the link below and then manually install the new version. Otherwise, be patient and your device should update itself eventually.
