Yep...First download the latest version of the Play Store.
The new version is horribly pale green and personally I don't like it.
Anyway it's version 4.0.26 and you can get it from:
After downloading, you will have to go into your Security settings and tick the option for "Unknown Devices" allowing you to install apps from outside the Play Store.
then install it from your Downloads folder
It looks quite good actually if you use facebook a lot.
Didn't allow it to always load "always" instead of Sense 5 so I could switch it off.
I uninstalled it today actually...
Tell me what you think.
I have a Vodafone Contract HTC One...It gets rid of all Vodafone recommendations too...the version I had installed previously was 3.1 something...way behind the stock version...As it treats it as an upgrade you can always uninstall Play Store too if you want.
