Having trouble accessing the Windows Phone Store on your Windows Phone 8 handset? You aren’t alone it seems. Wpcentral reports that “error 805a0193” is displaying for many users attempting to grab an app from the store.
Unfortunately, there are no details from Microsoft as to what this error message is about, what’s going on and when it will get back up and running. Interestingly enough, Xbox LIVE’s status page seem to be working fine and doesn’t indicate any issues being reported with any service.
Hopefully Microsoft gets it all straightened out soon. Do you have a Windows Phone 8 handset, are you currently experiencing this error or not?[ source ]
