Product-related reviews are based on users' experiences that are mostly shared on videos in YouTube. It is the second most popular website globally in 2021. People prefer to watch videos on recently released products prior to purchasing, in order to gather overall feedback and make worthy decisions. These videos are created by vloggers who are enthusiastic about technical materials and feedback is usually placed by experienced users of the product or its brand. Analyzing the sentiment of the user reviews gives useful insights into the product in general. This study is focused on three smartphone reviews, namely, Apple iPhone 13, Google Pixel 6, and Samsung Galaxy S21 which were released in 2021. VADER, which is a lexicon and rule-based sentiment analysis tool was used to classify each comment to its appropriate positive or negative orientation. All three smartphones show a positive sentiment from the users' perspective and iPhone 13 has the highest number of positive reviews. The resulting models have been tested using N\"aive Bayes, Decision Tree, and Support Vector Machine. Among these three classifiers, Support Vector Machine shows higher accuracies and F1-scores.

This year's iPhone could do away with the "notch", swapping it for a small hole for the camera and putting Face ID under the screen, according to a new report. The design would be the first major change to the front of the iPhone in years, as well as requiring technology not yet seen in any iPhone. In recent iPhones, all of the hardware required for facial recognition and the front-facing camera are nestled in a notch at the top of the display. The screen wraps around the side of that notch, but the black components are visible at the top. The new report suggests that the more premium versions of this year's iPhone 14 would instead take some of those components and put them under the display.

Apple has released its latest firmware updates for iPhone and iPad. One of the more notable features Apple is adding in iOS 15.2 and iPadOS 15.2 is the Voice Plan for Apple Music. For $5 per month, subscribers can access the full library of songs, playlists and radio stations via Siri. On iPhone and iPad, you'll be able to access an App Privacy Report, which provides details of the data that Apple and third-party apps accessed during the previous seven days. The report shows how often apps use things like location, photos, camera, microphone and contacts, as well as their network activity. Also new is Apple's Digital Legacy feature.

Apple is easing restrictions on how its products are repaired following an iOS update that now lets third-party repair shops replace broken iPhone 13 screens without consequence. Originally the Face ID would be disabled if a service provider not authorized by the tech giant did the repair, but now the new iOS 15.2 beta has stopped the facial recognition system from cutting out. In a video showing the new operating system, iCorrect notes that following a DIY screen swap an'Important Display Message' warning appears that means the iPhone is unable to verify the new display is a'genuine Apple part.' The update comes just as Apple announced its upcoming Self Service Repair program on Wednesday that will let customers fix their own iPhones and Macs by ordering necessary'Apple approved' parts and tools. Originally the FaceID would be disabled if a service provider not authorized by the tech giant did the repair, but now the new iOS 15.2 beta has stopped the facial recognition system from cutting out The change, first confirmed by The Verge, is a huge win for the right to repair movement that has been putting pressure on Apple to let customers choose their own repair shops to fix broken devices.

Apple says it will release an update to address an issue related to iPhone 13 screen repairs that could disable the device's Face ID feature. Details on the issue were first reported by tech site iFixIt, which reported a small chip paired to the iPhone 13's screen renders Face ID inoperable when the screen is repaired. The site said the change would have significant impacts on users or repair shops aiming to replace screens on the iPhone 13. "One of the most common phone repairs that could once be done with hand tools now requires a microscope," said iFixIt. "This means you won't be able to fix your iPhone screen yourself without sacrificing major functionality." In a statement emailed to USA TODAY, Apple spokesperson Nick Leahy said "a solution will be available in an upcoming software update."

Scientists have found a way to make'soft robots' using balloons that change shape when inflated with air. This new technology has been used to create a robot with a gripping hand, a flapping fish tail, and a moving coil that can be used to retrieve a ball. In contrast to conventional rigid robots, these soft robots are "naturally geared to interact with the soft stuff, like humans or tomatoes", assistant professor of chemical and biological engineering at Pierre-Thomas Brun at Princeton says. This could make them significantly more useful for harvesting food, taking items off a conveyor belt, or providing health care – as part of wearable exosuits or under-the-skin devices that could help people with heart issues. The robots are built by injecting bubbles into a liquid polymer called elastomer which becomes rubbery when it solidifies, then inflating the device to make it bend and move.

Soon after the iPhone 13 was released, an iFixit teardown showed that Face ID stopped working if the display was replaced by a third-party repair shop, unless they transferred a microcontroller from the original screen. Apple will soon mitigate the issue with an upcoming software update, so Face ID will still function even without swapping the chip to the new display. "A solution will be available in an upcoming software update," Apple told Engadget. The Verge first reported on the forthcoming fix. Moving the microcontroller from the device's original screen to a replacement is no easy feat -- iFixit noted a microscope is needed.

The Pixel 6 is the most intriguing phone Google has made in years. Not only is it a return to premium design with eye-catching colors and up to a 120Hz screen, it's also powered by the company's first mobile processor -- Tensor. With it, Google is promising serious improvements in AI performance and photography, including better voice recognition and Assistant features. Google also finally upgraded the Pixel's camera hardware instead of just relying on its processing smarts. That's not to say it's overlooked software this year.

With the addition of features like a 120Hz display on some models, Apple's iPhone 13 lineup is many ways a step above the phones the company shipped last year. But when it comes to the question of repairability, the story is more complicated. Conducting a teardown of the device, iFixit found it couldn't get the iPhone 13's Face ID feature to work if replaced the phone's display. No matter what workaround it tried, iFixit could not get Face ID to work again. By its estimation, the display on the iPhone 13 lineup is serial-locked to the device.
