Reliance Jio has created a wave of disruption in the telecom market once again with its plan of launching a new 4G VoLTE feature phone having a price tag as low as Rs 500.
The big announcement of the launch could be made at Reliance Industries' annual general meeting on July 21, 2017. 


Jio 4G feature phone is said to have a 2.4-inch display, 512MB RAM, 4GB internal storage, microSD card support, 2-megapixel rear camera, VGA front camera, Wi-Fi, GPS, and NFC.

Vivo beats Apple to an under-display fingerprint sensor

At MWC Shanghai, Qualcomm announced its latest ultrasonic fingerprint solution, with the new highlights being its integration underneath OLED displays (up to 1.2mm-thick), as well as working fine even when the device is immersed in water

Ultrasonic fingerprint sensor 

Let’s take a closer look at how this technology works and what sort of advantages it has to offer over current fingerprint scanning technologies on the market.
Rather than existing photographic or capacitive based fingerprint scanners, Qualcomm’s Sense ID makes use of ultrasonic sound, as the name implies, in order to map out the details of the user’s fingerprint. Fortunately, there’s no need to swipe, just touch the finger to the sensor like the top of the line capacitive fingerprint scanners.
To actually capture the details of a fingerprint, the hardware consists of both a transmitter and a receiver. An ultrasonic pulse is transmitted against the finger that is placed over the scanner. Some of this pulse is absorbed and some of it is bounced back to the sensor, depending upon the ridges, pores and other details that are unique to each fingerprint.
There isn’t a microphone listening out for these returning signals, instead a sensor that can detect mechanical stress is used to calculate the intensity of the returning ultrasonic pulse at different points on the scanner. Scanning for longer periods of time allows for additional depth data to be captured, resulting in a highly detailed 3D reproduction of the scanned fingerprint
This is considerably different to even the best capacitive fingerprint scanners on the market at the moment, which are only able to reproduce 2D images. 3D details are much more difficult to forge or fool than 2D versions of the technology, potentially making the ultrasonic system much more secure.
Another added perk of this ultrasonic fingerprint scanner technology is that it allows the fingerprint scanner to still operate through thin materials, such as a smartphone case built from glass, aluminium or plastic. Therefore, the scanner can be embedded under the case, allowing for a more discrete look. Additionally, there’s less chance of damaging the sensor or exposing it to external tampering, and sweat or moisture on the finger won’t interfere with the scanning process either.
The demo started off with a familiar fingerprint registration process, except I had to place my finger on a marked area on the screen, which was just above the old fingerprint button. Once done, I was able to unlock the phone by touching that same spot using my registered finger; and just to be sure, I tried with my other fingers which fortunately failed to unlock the device.

While the solution seemed to work as advertised, I found the fingerprint recognition speed to be noticeably slower -- about one second between first touch and entering home screen -- than the near-instantaneous unlock that I'm used to on most recent smartphones. I was also slightly disappointed by how small the recognition area was. That said, Vivo's demonstrators told me that in theory, the same sensing technology could be applied across the entire screen, but that would significantly increase production cost; instead, Vivo might eventually cover just the bottom half of the screen, which would still be better than what the demo offered.

In another demo, the company applied the same ultrasonic tech to a spot on the back of the phone's metallic body, thus allowing the phone to be unlocked even when placed in water. Since this unlock method could be associated with the camera app, this could come in handy for those moments when you want to take underwater photos or videos while in shallow water. But of course, other companies have solved this use case with a physical shutter button (Sony) or squeeze detection (HTC).
The Vivo reps couldn't provide a timeline as to when we'll start seeing this tech on their devices, but according to Qualcomm, its solution will come in two waves. "Qualcomm Fingerprint Sensors for Glass and Metal" can be integrated into devices powered by Snapdragon 660 and 630, and it'll start shipping to OEMs this month. As for the more advanced "Qualcomm Fingerprint Sensors for Display," it'll work with future Snapdragon platforms as well as non-Snapdragon platforms, and it'll only start commercial sampling in Q4 this year.

Android O Top features

Google has announced second beta version of Android O in Google I/O event with lots of features. The Android O only launch its beta version the full version will be released in August. Let's get started with the top new features.
Google is adding a Picture-in-Picture mode to Android O. With a YouTube video playing, just tap the Home button and the video will pop into a small window that can remain on screen as you navigate other apps on your device. You can slide the video around for best placement, then simply slide it off the screen to terminate. Available now in the Android O Beta.
Notification Dots
Android O users will see a small dot that appears over top of their app icons with active notifications. now that your app has an icon, new tools are available in Long-press the app icon with Notification Dot to get a short list of immediate shortlink actions you can perform. This includes viewing the notification itself right there in a tiny pop-up window. This feature seen the today's iPhone.
Smart Text Selection
We’ve all seen the basic text highlighting features, the copy/paste dialogue in Android, but now there’s more. With Android O, highlighting text includes further features, using Google AI to intelligently act on the words. For instance, if you highlight a phone number, you can just tap to dial. If you highlight an address, a single tap will start navigation. Best of all, highlighting is more intelligent itself, selecting phrases or full addresses, for example, instead of just single words.
Navigation Bar Tuner
Android Marshmallow introduced a hidden menu called the System UI Tuner that let you tweak the appearance of various system icons and menus. Android O has now expanded on the options available here, and perhaps the biggest improvement is that it now allows you to change your on-screen navigation buttons.
If you head to the Navigation Bar menu in System UI Tuner, you'll be able to tweak the layout of your on-screen buttons, and even add a couple extra icons to flank them. Layout options allow you to condense the spacing of the buttons or shift them over to one side, while the "Extra button" option let you add a clipboard button or keyboard switcher to either side of your navigation bar.
Custom Lock Screen Shortcuts
Another great addition to the System UI Tuner is a new lock screen shortcuts menu, which does exactly what you'd think: It lets you add custom shortcuts that will show up in the bottom corners of your lock screen. You can pick any installed app to occupy one of these spaces, and there are several handy shortcuts to choose from, such as one that opens your selfie camera directly.
