An embarrassing glitch has reemerged on iPhone, judging from complaints online -- a bug that dredges up old web searches many would like to keep private. Some Apple users are discovering that their devices are displaying old adult content at unwanted moments, despite their best efforts to clear their browser history, tabs and cookies, even after making sure to view risqué content in'incognito mode' only. 'I have a fairly new iPhone and this is happening,' one Apple fan confessed. 'Old porn vid stuck in Firefox preview mode, only happens in landscape [mode] though.' Another user told horror stories of their iPhone displaying old adult content while'people have been looking over my shoulder as I am showing them something.'

Users of the latest iPhone Pro models are just getting to grips with the functions of a mysterious black circle next to the cameras on the back of the latest iPhone models. A recent Reddit post with 1,400 upvotes saw a user circling the mysterious circle and asking simply, 'What's it for?' The circle is only found in the latest iPhone Pro models and certain iPad Pro models - and it's actually very useful, enabling some of the device's coolest apps and features. The dot, which is built into the camera array, is actually a LiDAR scanner (it stands for Light Detection and Ranging). The black'dot' can be seen here on an iPhone 14 Pro (Apple) The sensor enables the Measure app to work out people's height (Apple) Put simply, it's a depth sensor which uses lasers to work out how far away things are.

Apple launched the first developer beta for iOS 15.4, which provides an opportunity to test upcoming features planned for the iPhone. Among them is the ability to use Face ID while wearing a mask. Currently, the only way to unlock iPhones with Face ID and a mask on involves owning an Apple Watch. The iPhone has an option to unlock the phone with Apple Watch. Once enabled, users wake their iPhone then glance at the screen to unlock it.

In the last two years, true wireless earbuds have made quite the leap. There's no doubt the popularity of Apple's AirPods helped make these headphones a mainstay, but companies' ability to offer reliable connectivity, great sound and active noise cancellation (ANC) in an increasingly smaller form factor has hastened widespread adoption. You can also get features that used to be reserved for premium models on mid-range devices. Of course, the popularity means that new earbuds are popping up all the time and the list of options is longer than ever. To help, we've compiled the best wireless earbuds you can buy right now, including noteworthy features for each selection.

Apple confirmed a theory many users have had for years: the iPhone gets slower with age. The confirmation comes after Reddit users noticed their devices were getting slower as the batteries in their iPhones got weaker. Apple heads into the new year with some unusually downbeat news: its new iPhone X isn't proving to be quite the sales darling that some of its previous smartphones have been. Shares of Cupertino tech giant were down 3% in early trading Tuesday after several market analysts forecast lower than expected demand for the latest iPhone, with its edge-to-edge screen, face-recognition software and lofty price. Apple could cut its sales forecast for the first quarter of 2018 to 30 million units, down from an initial target of 50 million, according to a report in Taiwan's Economic Daily News cited by Reuters.

In its quest for hardware perfection, Apple can't seem to resist testing the balance between making things easy and making them secure. Sure, a six-digit passcode is virtually impossible for a thief to crack before his repeated attempts lock the phone, but it demands an unacceptable fraction of a second for you to tap it out. Even TouchID requires a home button that Apple has deemed unsightly. Now, in its continuing war on inconvenience, Apple has replaced TouchID in its new flagship iPhone X with FaceID, a system where your face acts as password. In doing so, it's about to give an unproven biometric security technology its biggest field test yet.

USA Today's Ed Baig tries out Samsung's new smartphone before it hits store shelves. Samsung Electronics' Galaxy S8 and S8 smartphones are shown off during a media day in Seoul, South Korea, (Photo: Lee Jin-man, AP) NEW YORK--Samsung's Galaxy S8 and its larger sibling the S8 are strong new smartphones I can highly recommend. The devices, which hit stores Friday (for around $720 on up), aren't perfect. Cool-sounding features like iris and facial recognition were extremely spotty for me. Water and dust resistance are great, but other phones now share these traits.

The idea of talking conversationally to computers has been a long time in the works. Science fiction is so often a self-fulfilling prophecy as it provides a vision for humans to chase after with technological innovation. For those of us who have watched voice-based computer interactions evolve, we have seen it go through many manifestations as it grew up. We now find ourselves in a world where using voice to interface with a computer is commonplace on a regular basis for the masses. While I'm not quite confident we have reached an inflection point, I am confident we are at least on the cusp of one with voice-based user interfaces and the vision of the Hal 9000 (The AI assistant of Arthur C. Clarke's Space Odyssey series) and Jarvis (the voice based AI assistant of Iron Man).

I'll be honest: Even though I'm supposed to be a technology expert, I've long resisted using Siri and my smartphone's voice commands. All the errors were frustrating and often seemed to eat up more time than just typing in commands and opening up apps manually. These days, though, I've found myself using Siri more often. Speech recognition has gotten a lot better, and Siri has gotten a lot smarter and more powerful. You can do virtually anything via your phone's voice commands, from posting to Twitter to finding the best pizza pie to figuring out just how deep 20,000 leagues really is.
