Hello everyone, here are some current news stories events involving smartphones today.
As always enjoy.
iOS Bug Crashing iPhones Simply by Receiving a Text Message
Apple says today it has a fix in the works for an odd software bug that has been able to crash users’ iPhones when they receive a text message with a specific string of characters. The bug, which involves having users send a string of symbols and Arabic characters to a victim’s iPhone (show below).

Sending this text string to a user’s iPhone causes the device to crash and then quickly reboot. Afterwards, if the Messages app was opened in list view, it will continue to crash when you try to open it going forward. If it was opened to the conversation view, however, the app will open. But when you try to enter in another conversation, the Messages app will crash again.
Tracking Metro Riders Using Accelerometers on Smartphones
We know that we can be tracked using GPS data from mobile phones, which can triangulate location from nearby cell towers.
The reason that metros are so prone to this type of attack is that they run on fixed rails, for fixed distances, unlike the more complex combinations of multilane highways and roads across which cars or buses zigzag.
Given the fact that each metro system has a finite set of twists and turns and distances that culminate in a unique “fingerprint,” accelerometer data could be used to trace us, the researchers say.
From the paper:
The cause is that metro trains run on tracks, making their motion patterns distinguishable from cars or buses running on ordinary roads. Moreover, due to the fact that there are no two pairs of neighboring stations whose connecting tracks are exactly the same in the real world, the motion patterns of the train within different intervals are distinguishable as well.
As far as surveillance goes, accelerometers beat GPS or cell service, which both drop out in tunnels.
The research paper, titled We Can Track You If You Take the Metro, comes from three researchers at Nanjing University’s Computer Science and Technology department.
They point out that this isn’t the first time we’ve heard that accelerometers can be used for purposes other than their intended use.
Office Lens Android now available at Google Play Store
Office Lens turns your Android, iPhone or Windows Phone into a pocket scanner that works “flawlessly,” delivers “crystal clear images” and does an “excellent job of transcribing a printed page. The handy scanner app recognizes the corners of a document, whiteboard, electronic screen or any rectangular media and automatically crops, straightens, enhances and cleans up the image, then enables saving to OneNote or OneDrive for easy retrieval from any device. Apple users can also get the full version of Office Lens in the App store for free.
It offers the following capabilities and features across all three phone platforms:
- Converts images of paper documents, electronic screens and whiteboard notes into Word documents, PowerPoint presentations and searchable PDF files for easy storage, editing and reformatting.
- Enables images to be sent via email, making it easy to share whiteboard notes with work colleagues, submit scanned business expense receipts or ensure family and friends have copies of important paper documents.
- Captures business cards and generates contacts, which can be sent to OneNote and added to your phone.
- Recognizes the corners of a document and automatically crops, enhances and cleans up the image.
- Identifies printed text with optical character recognition (OCR) so that you can search by keyword for the image in OneNote or OneDrive.
- Inserts images to OneNote or as DOCX, PPTX or PDF files in OneDrive, providing options to save, export and share the image. (It’s easy to decide where to save images and keep them organized.)
