Microsoft is investigating a glitch on some of its Windows Phone 7 handsets which is causing huge chunks of 'phantom' data to be sent and received automatically.
The glitch deals a serious blow to Microsoft’s ambitions to storm the smartphone market with its flagship Windows Phone 7 portfolio.
Windows Phone 7 users have reported on various forums that up to 50MB of data being sent from their phones, without their permission. The problem seems more widespread in the U.S.
One user reported: ‘I went and looked at my AT&T account online and noticed that my phone was sending huge chunks of data seemingly in patterns. For instance on November 21-24 it sent between 30 and 50MB of data at 10:41pm each day and Dec 1-4 it sent between 30 and 50MB of data at 9:41am each day.
'On December 23rd I turned on airplane mode so my phone could no longer send data. I turned airplane mode off briefly on December 23rd and the phone sent 400MB of data. I called AT&T yesterday, December 28th, but they said that there was nothing that they can do to figure out what was happening on my phone.’
A Microsoft spokesman said the company is investigating the problem.
