Android 5.1 update on your Nexus device, how Google manages updates

Android 5.1 update on your Nexus device, how Google manages updates


Waiting for the Android 5.1 update on your Nexus device? You’re not alone, here’s how Google manages updates
If you keep hitting “check for updates” on your Nexus device, you are just wasting your time, and stressing your fingers. We know, we don’t like to wait for the OTA update either.

Having your device constantly check for updates is about as effective as repeatedly hitting a floor button on an elevator – it’s not. As it happens, clearing Google Service Framework data doesn’t help either, in fact, it will actually hurt your chances of getting an update in a timely manner.

We dug through the interwebs to find some information about how Google manages Android updates, et voila, we found an explanation by Google’s own Dan Morrill, an Android Engineer, on Reddit. He shared these pearls of wisdom a little over a year ago when Android 4.4 KitKat started rolling out, but let’s rehash these things as they touch on both tactics for trying to get Android updates, and explain perfectly why they don’t work.

Taking the latter issue first, if you clear the Google Service Framework data, Google’s servers see this as factory reset, changing the primary ID for your device. Doesn’t sound like a big deal right? The problem is that it invalidates all the app tokens which, in turn, wreaks havoc over notifications. In short, you won’t brick your device, but you are not getting it to the front of the line trying to grab the newest OS update.


As for continuously “checking for updates,” it is not unlike knocking at the door when no one is home. The updates are pushed out in phases. The first phase lasts 24-48 hours, and will reach about 1% of devices initially. The engineers then examine error reports and how the devices are checking in.

If all is going well, then the second phase will push out to about 25% of the install base. Assuming there are no further problems (if any), then the following phase will reach 50%, and so-on over the next couple of weeks.

How does that translate to you the user? Well, if you hit “check for updates” during the first phase, basically you have a 1% chance of getting the update. If your device is not randomly selected to receive the “offer,” then you are on the sidelines until the next phase starts. In Morrill’s own words, “Once your device checks in and gets turned down, that’s it until the next batch. Mashing on the ‘check for updates’ button just causes yourdevice to check in again, and get automatically turned down again. Think about how that makes your device feel! WON’T SOMEONE PLEASE THINK OF THE PHONES?”

As you may expect, the next phase gives your device another shot at hitting pay dirt for the update, but again, once the device checks in, that is it for a given 24-hour period usually.

If it’s any consolation, the “offers” are random, updates are not handled on a first-come, first-served basis. While that means there is no “race” to get the update first, we kind of wish it was sometimes.

Chech this out, Screenshots leaked testing of WhatsApp Voice Calls for the Apple iPhone

Screenshots leak testing of WhatsApp Voice Calls for the Apple iPhone 

 Screenshots leaked testing of WhatsApp Voice Calls for the Apple iPhone

 
Last month, we showed you how to enable WhatsApp's calling feature on your rooted Android phone. The feature should eventually be included with the version of the messaging app available from the Google Play Store. Meanwhile, an Indian iPhone user has taken screenshots of what looks to be the WhatsApp calling feature running on his handset.

Voice calls on the iPhone version of WhatsApp requires that you have version 2.11.17.444 of the messaging app, which is in beta. It can be installed only on a jailbroken iPhone. The version of WhatsApp that currently populates the App Store is 2.11.16, which of course doesn't include the calling feature.

The screenshots show small changes to the UI and a phone icon underneath a user's profile picture. Clicking on the call button brings up a dialer similar to the one on the iPhone. A "Recent" button on the bottom of the page will show a recent history of calls made using the app.

Although we have no idea when this will all be made available for iOS users, it feels like it has been a long ride since we first alerted you to the possibility that voice calling would be added to the popular messaging app. Last week, an Italian iPhone site tested out the feature and posted a video of the test. Even if you don't speak Italian, it is worth viewing just to check out the feature in action. That video is part of our slideshow below. Feel free to check it out!

Samsung, BlackBerry and IBM team up together to produce a high security new tablet

Samsung, BlackBerry and IBM team up together to produce a high security new tablet

 
BlackBerry, in conjunction with Samsung and IBM, has introduced a secure tablet that will launch sometime this summer. The slate will be priced in the area of $2380. Called the SecuTablet, the device is based on the Samsung Galaxy Tab S 10.5. The tablet employs the Secusmart encryption technology that is now owned by BlackBerry after the latter's acquisition of Secusmart last July.

Secusmart's encryption technology is already employed by the German and Canadian government and is used to prevent people from spying on the slate. IBM's contribution is software that enables the user to securely separate work and personal apps on the same device. Hans-Christoph Quelle, Secusmart's CEO, says that anyone who knows how to use Android should be able to work the tablet.

The BlackBerry PlayBook tablet was launched in 2011 and no sequel was ever released. Shockingly, the slate came to market without an email client or a calendar, omissions that were corrected by a future software update. The device was powered by the QNX OS, which was used to build the BlackBerry 10 OS. With the hefty price tag, the SecuTablet is obviously a device for business users; this is a market that still counts on BlackBerry's focus on security.

The Samsung Galaxy Tab S 10.5 features a 10.5-inch Super AMOLED screen with a resolution of 2560 x 1600. That works out a pixel density of  288ppi. Powering the slate is an octa-core 1.9GHz Exynos 5420 CPU. The ARM Mali-T628 MP6 GPU handles graphics. 3GB of RAM is on board along with 32GB of native storage. Those needing additional memory can turn to the 128GB capacity microSD slot. An 8MP camera is on back while a 2.1MP shooter adorns the front of the tablet. A 7900mAh battery keeps the lights on, and Android 4.4.2 is pre-installed.

Google just acknowledges leaky memory, is fix coming to Android 5.1.1 or not ?

A memory leak that was originally discovered in Android 5.0.1, is still annoying and befuddling Nexus device users with Android 5.1. According to the Issue Tracker page on the AOSP website, Google has internally fixed the issue and plans to include it in an upcoming release. That most likely would be Android 5.1.1. 

The complaints are beginning to read the same. Apps, especially Google+, restart on their own. Some active apps disappear in the middle of using them, and free RAM drops in hours to about 750MB-800MB from 1.1GB-1.3GB. Most of the people who sent in a complaint appear to be using the Nexus 5, although other Nexus devices have been cited. Some complaints said that opening apps would increase the amount of RAM in use, but closing apps would not reduce that figure.

Issue 159738, "Memory leak still present on Android 5.1," was closed by Google on Friday. Now, it is just a matter of waiting for Android 5.1.1. Google will no doubt stamp this as "Rush" because no one wants to live with the craziness of a handset running with a memory leak.

Thanks for the tip Rodrigo!

lol, Apple’s digital assistant Siri have mood swings or not ?


Does Apple’s digital assistant Siri have mood swings? 

Apple’s digital assistant Siri have mood swings

 
When it comes to Siri, Apple loves to tout its digital assistant’s personality, recently enhanced with the update to iOS 8.

Apple likes happy. Apple users like happy too. All the major players are vying to add quirky personalities to their digital assistants. Microsoft’s Cortana probably still has some of the best responses we have seen in a while, but that is not to say Google Now or Siri are not without their nuances.

One guy in Southern California was asking Siri some questions on his iPhone 6 when it seemed to him that the digital assistant was not sounding so chipper anymore. Siri doesn’t have a mood ring, and the Apple Watch is not yet available for him to buy and make “her” happy.

That’s when he got an idea, a “mind blowing” idea. He grabbed his wife’s iPhone 6 and ran a side-by-side comparison of how Siri responds to inquiries from each device’s owner. Both devices are identical and running iOS 8.2. The settings for Siri are also identical, female voice and “American English.”

It is far from a scientific test, but we have to agree, Siri sounds far more upbeat talking to its female companion than when it responds to her spouse on his iPhone. Coincidence? Who knows. Do you have a family of iPhones in the house? How does Siri respond to your family members? Let us know in the comments below.
