Microsoft investigates 'phantom' Windows Phone 7 data


Recommended Posts

Microsoft has told BBC News that it is investigating why some handsets running its Windows Phone 7 software are sending and receiving "phantom data".

Several net forums detail complaints from people that say their phones are automatically eating into their monthly data plans without their knowledge.

Some have complained that their phone sends "between 30 and 50MB of data" every day; an amount that would eat into a 1GB allowance in 20 days.

Most complainants are based in the US.

"I received an e-mail from AT&T saying that I was close to my 2GB data limit which truly shocked me as I feel I do not use data that much," a phone owner called Julie told Paul Thurrott's supersite for Windows.

"I went and looked at my AT&T account online and noticed that my phone was sending huge chunks of data seemingly in patterns."

Another said that they had noticed that the phone's "idle data usage is around 2-5MB per hour".

"This seems quite excessive to me - what exactly is being transferred? This even happens at night when I'm not getting any e-mails at all," they wrote on Howard Forums.

Some have speculated the problem may be related to the phones sending "feedback" to Microsoft about the software's performance or that the phones are using a 3G connection even when wi-fi is available.

"We are investigating this issue to determine the root cause and will update with information and guidance as it becomes available," said a Microsoft spokesperson.

Windows Phone 7 was launched in October 2010 to acclaim by manufacturers and users.

It is considered the company's first credible challenge to rival operating systems from Apple, Google, Research in Motion and Nokia.

At the recent Consumer Electronics Show in Las Vegas, Microsoft boss Steve Ballmer said that the firm would soon release "a series of platform improvements" in response to users' feedback.

These will include copy and paste capabilities and performance improvements when loading or switching between applications.

Wow, this is a serious fail on Microsofts part. Windows Phone 7 was not ready for prime time, they rushed it.

At least we've got two good phone OS remaining, Android and iOS.

Apple has made quite a few monumental mistakes as well. That said this can't happen. I hope MS and AT&T are ready to refund all customers affected.

here is my usage on the phone starting two days ago. nothing seems to be out of place on my network (t-mobile)

There have been a few reports about similar occurrences with iPhones on AT&T's network a few months ago... see the common denominator?

here is my usage on the phone starting two days ago. nothing seems to be out of place on my network (t-mobile)

Now that's interesting... Maybe MS isn't to blame after all? But how can they force data onto a device?

Are you using WP7? I wonder if this is an AT&T thing then?

Wow, this is a serious fail on Microsofts part. Windows Phone 7 was not ready for prime time, they rushed it.

At least we've got two good phone OS remaining, Android and iOS.

Windows phone 7 here and no "ghost" data.. and i wouldn't touch a droid with a 10 foot pole and our house is glad to be free of iOS forever.

It was but all the Android fans like Subject Delta and alexweb obviously wanted another opportunity to troll.

Ha ha funny that -.- But at least get my username right next time okay? :p Back to the topic, don't how this could be a network thing, I mean there's no AT&T software in the phones.

AT&T doesn't provide any crapware with WP7?

Ha ha funny that -.- But at least get my username right next time okay? :p Back to the topic, don't how this could be a network thing, I mean there's no AT&T software in the phones.

AT&T Windows Phone 7 devices come loaded with AT&T FamilyMap, AT&T myWireless, AT&T Navigator, AT&T Radio, and AT&T U-verse Mobile :p Whether any of those apps update in the background I have no idea, never seen them in action. Butt so far all the reports seem to be from AT&T users

<img>

are we sure its not a 3rd party app yet? that much data being send / recieved from a core OS seems outragious.. I can see some push updates / notifications but thats about it!

Hard to say what the cause could be, ut if Microsoft are investigating it, that means that it's an issue

I swear this was already reported...

I looked, and couldn't find any other topics about this

It was but all the Android fans like Subject Delta and alexweb obviously wanted another opportunity to troll.

Yep, because we all know the BBC are prone to posting unverified and false news stories (Y)

Sorry if this kind of thing spoils your Microsoft love in, but it is real news.

I've seen none of that with my Samsung Focus on AT&T. My guess is a third party app updating itself a little too often. None of AT&T's apps have any reason to update themselves in the background and its too limited to too few people to really be anything other than some random app.

I have yet to encounter this problem and I consider myself a power user on my Samsung Focus with Rogers... 3x email accounts setup, downloading apps daily, taking pictures which get uploaded to windows live and facebook using my data plan... It all seems to be fine!

when I'm in wifi-range, turn off 3G, it's a nice little feature.

Unfortunately looking at the reports, even if 3G is off, the data waits until 3G turns back on to be sent, so it won't help anything :[

    • OpenAI is rolling out a major upgrade to ChatGPT memory by Pradeep Viswanathan OpenAI is rolling out a major upgrade to ChatGPT's memory, making the system more capable, current, and scalable across long-term use. Memory allows ChatGPT to remember useful details about users, including their preferences, projects, and constraints. Instead of starting every conversation from scratch, ChatGPT can use this context to provide more relevant responses in future chats. OpenAI first launched saved memories in February 2024. That feature allowed users to explicitly ask ChatGPT to save information into its memory, such as travel plans or writing preferences. However, this system had limits because it depended heavily on users giving clear instructions to remember something. Additionally, saved memories could become stale over time. In April 2025, OpenAI expanded memory by allowing ChatGPT to reference past chat context outside the saved memories list. This was powered by a background process called “dreaming,” which automatically curates memories from chat history. This made ChatGPT better at learning from natural conversation without requiring users to manually save every detail. Today, OpenAI announced a more capable and compute-efficient memory architecture built on top of dreaming. This new system improves ChatGPT’s ability to carry forward useful context, follow user preferences, and remain accurate as time passes. According to OpenAI’s internal evaluations, the new system improves factual recall from 67.9% in 2025 to 82.8% in 2026. Preference adherence improves from 55.3% to 71.3%, while accuracy over time improves from 52.2% to 75.1%. The best part of this new system is a new memory summary page where users can review ChatGPT's memories. Users can even update details, correct information, or give instructions on what topics ChatGPT should bring up and when. This new, improved memory system is available to ChatGPT Plus and Pro users in the US starting today. It will roll out to more countries, as well as Free and Go users, in the coming weeks.
    • I work for a video production company in Australia. The camera operators shoot footage and then pass the SD card over to the editors. Much easier than handing over the entire camera. Plus, on a busy day you can hand off the SD card and then pop another in for the next shoot. Or, you might have used multiple SD cards because you need the extra space for a long shoot. I also use USB cables and wifi for transferring footage, but in many cases an SD card reader is the easiest method.
