Smartphones can be divided into three price classes – entry level, mid-range and premium class. Resolution depends on display size – the larger the display, the higher the resolution should be.Compared to entry-level phones, mid-range devices run more smoothly, have higher resolution displays and more features. In the meantime, they are increasingly being used in cheaper mid-range devices," van de Sand says.Good mid-range models can be bought from US$300 (RM1,258) onwards. With Android devices, it can happen that no system updates come any more," Emunds says.This is the case not only with cheap devices. For entry-level and mid-range Android smartphones, a search on the Internet can help to find out a device's update policy.
Samsung announces long-anticipated foldable smartphone - Tech News
Samsung announced a major new phone at an app developers' conference in San Francisco on Nov 7 – and it's finally the foldable smartphone we've all been waiting for.During the keynote, Justin Denison, SVP of mobile product marketing, presented a "disguised" device, saying the company did not want to reveal the entire look yet.However, viewers were able to get a quick glimpse of a rather thick-looking phone that folds out to become a fully-fledged tablet, without any sign of hinge or crease on the screen's folding axis.The South Korean tech giant also provide some information about how they were able to create the device.The display is covered not by glass, which is notoriously inflexible, but by what Samsung has called an "Infinity Flex Display," which also uses an adhesive that, according to Samsung, allows the screen to be folded several thousand times without any degradation.The company also announced that the Infinity Flex Display could also be adapted to be rollable and flexible – and that they were ready to begin production of the displays within the next few months.The new phone will also be able to run three applications at the same time in an "multi-active window" that can allow several windows for apps to be open simultaneously.Google simultaneously announced that its Android smartphone platform would support the new folding format for smartphones, pointing to the ability to continue using an app as you switch between compact and folded-out mode. "Android apps run seamlessly as the device folds, achieving this form factor's chief feature: screen continuity," the developers said.Samsung did not reveal when the phone may come out, but experts expect the phone will hit the markets in the first half of 2019.China's Huawei has also announced plans to present a new foldable smartphone in mid-2019, whereas another China-based company, Royole, has already unveiled a foldable phone priced at US$1,300 (RM5,430), which will go on sale in December.
Heart-monitoring smartphone tech could save your life, research shows - Tech News
as mentioned in For the study, researchers tested an app that uses a electrocardiograph (ECG) lead to monitor your heart rate, and found that it was almost as accurate at diagnosing a heart attack as the standard 12-lead ECG used by medical professionals. However, the researchers caution that the Apple 4 smartwatch comes with just a single-lead ECG measuring just one part of the body. A typical ECG monitors heart rates at different parts of the body using 12 leads. This improves the accuracy of a diagnosis because heart attacks happen in different parts of the heart. The FDA noted that the device can fail to detect heart rate issues if the ECG has a bad signal, and that both false negative and false positives could occur in the software.Your old smartphone is a security risk. Live with it - Tech News
That obsolete smartphone stashed away in a drawer or closet may not look like a national security risk, but the Trump administration is contemplating treating it as one. To prevent that from happening, the US Department of Commerce proposes to severely restrict the export of used electronics. Then and now, strong developing-country markets for affordable used devices and parts – working or not – are what draw e-waste offshore. Export controls on used electronics weren't among the recommendations, and that's for a good reason. Who, then, would benefit from restrictions on used electronics exports from the US?
