Light could be the key to solving one of the big problems of faster mobile Internet. But the technology, which uses spotlights to send out signals, has some limited range of uses. The technology developed by pureLiFi works on a simple principle: ... rather than using radio waves to transmit data (as does WiFi), it uses light waves. A demo of the system uses ceiling spotlights which blast out light in a cone shape. To the human eye it looks like an ordinary constant light supply. In fact it's actually flickering at incredibly high speeds to create a pattern. 5G Signals Hurt By Walls A plug-in ' ... (view more)

Google has apologized for remotely switching on "battery saver mode" on some Android phones. It says it was an internal test that was mistakenly rolled out. Battery Saver is an optional mode first added to the Android system in 2014. It aims to find ... a balance between reducing battery drain and maintaining convenience and functionality.

It also disables ... (view more)

Samsung Provokes Debate with Claims that Smartphones Are The Most Secure for Cryptocurrencies Last month, leading Samsung author Joel Snyder penned a blog post in which he made the bold assertion that smartphones encompass the best security for ... owning, trading and managing cryptocurrency.

Google has been tracking mobile device users movements even when they have "Location History" switched off. It turns out users need to turn off a less well-known setting to stop tracking altogether. The issue doesn't just affect devices running ... Android. Some iPhones are also affected if they have Google apps such as Maps or Search running. In theory, switching off the Location History setting on your device or in a Google account will prevent the company tracking and storing location information. The immediate effect is visible as the timeline feature in Google Maps will stop updating. ... (view more)

Officials in Europe want all phone companies to use the same technology for charging mobile devices. If the rules go ahead, it could mean Apple has to ditch its custom 'Lightning' port, and Qualcomm's 'Quick Charge' (used by Android devices). The ... European Union is running an "impact assessment study" to decide whether to push the policy and if so, whether to seek a voluntary agreement or impose rules. If it opts for the latter, manufacturers might decide it is easier to use the relevant charging port format worldwide rather than make specific handsets for Europe.

Samsung phone owners say they were shocked to discover photos from their phone were being sent to random contacts. An update to SMS text messaging appears to have caused the bug. One user says the entire contents of his photo gallery was sent to his ... girlfriend's phone via text message. His own phone had no record of the messages being sent and the first he heard of it was when his girlfriend asked him what was happening. Other users report similar issues, with no obvious pattern as to who received the images other than being in their contacts list. Reports suggest the problem is with the ... (view more)

Samsung looks set to release a phone with a giant foldable screen. But rumors of the price are varying wildly. Reports suggest that the phone will fold out a little like a book. When open, the screen will be more than seven inches across, meaning it ... resembles a small tablet computer. When folded, the device will be the size of an ordinary smartphone and, although a little thicker than most phones, should fit easily in a pocket. The idea is that the design would dramatically change what's viable with a phone. For example, working on document editing would be much more bearable for the user. It ... (view more)

Infopackets Reader Steve G. writes: " Dear Dennis, Thank you so much for your article on How to Disable Full Screen Popup Ads in Android ! Lately I have been inundated with full screen ads appearing on my smartphone and I have no idea where they are ... coming from. I tried your suggestion in the article, which says to wait for the full screen ad to appear, then press the app button on my phone to see where the ad is coming from. The problem is that these full screen ads don't have a title, so unfortunately I can't tell where the ad is coming from. You also suggested using a firewall but I am not ... (view more)

Infopackets Reader Sam G. writes: " Dear Dennis, I work from home and also own an Android smartphone, which I use to communicate (via text messages) with friends and family. Because I am home all the time, I use WiFi on my phone instead of data. ... Therefore, I purchased a very cheap 'pay as you go' data plan for when I'm away from the office. The problem is that my data is being eaten away by apps on my phone whenever I'm on the go. I have tried disabling 'background data' on my Android phone to limit which apps can use data, but this is incredibly time consuming because each data permission is ... (view more)
