Android P was first released in March, but it’s still known as “Android P” . Google has not named it yet, But intrestingly, in recent Instagram post from Google, Google has released sets of new 5 wallpapers to their followers. (Yes, google do like Instagram and has 6.2M followers)
Here is the link to Google Instagram: https://www.instagram.com/google/

These wallpapers are more like other Google's fancy wallpaper but among them, one stands different from other . Hope this does ring bells. That could be a hint from Google about the name of next release.

Or Google is just being witty and trolling their followers :)

Interestingly, Google named it Pie

How to open Chrome Browser inside Firefox Browser

I am sure you must have seen the movie Inception by Christopher Nolan. The movie is based on a wild theory of dreaming inside a dream. Though we cannot dream with Firefox but the trick is to open a browser inside Firefox. Yes, you can open a new browser tab in the browser tab. That sounds confusing as the movie was.
Here is a screenshot to simplify your thought.

FireFox Inception

This is what you need to do

• Open Firefox
• Type chrome://browser/content/browser.xul  in the address bar
• Press Enter

Baam! Inception.
Please note: That is .XUL which is XML User Interface Language by Mozilla for building user interfaces of applications like Firefox.

Something to wonder here - how must I have got the screenshot of the webpage in this webpage while creating this webpage.

[Solved] File Pasted on Desktop is not Visible

Like everyone else I also had a problem once with my Windows 7. The Desktop was not getting refreshed automatically. I copied and pasted a file to my Desktop and it was not there. I pressed Ctrl+V and Windows says do "There is already a file with same name in this location". I was surprised, if its there why can't I see it.
After few searches over Google, found the answer to it.

Before we start, A word of caution. Please Create a backup of your Registry. In-case you mess-up (I am sure you wont), backup will resolve.
Steps to Backup Registry:
Click Start 
Type regedit in the search box and click regedit item appearing in the list.
Click Continue, if you're prompted by User Account Control.
From the Left Pane, select Computer
Go to File and then Export and save the registry file.
To restore, just do an "Import" of registry in the registry editor.

Here is what you need to do,

• Press Windows+R and type regedit 
• Right click on HKEY_CLASSES_ROOT
• 
• Click "Find"
• Type dontrefresh in the search box and hit Enter
• Once search is complete, in the Right pane you will see DontRefresh
• The Data value will probably be set to '1'
• 
• Right click on "dontrefresh" and modify the value to '0'
• Reboot your computer.

That's it, this would resolve the issue 

Difference Between Enterprise Wipe, Device Wipe and Enterprise Reset

"Let me do an Enterprise Reset to you device" OR "Let me Wipe your device remotely."You might have heard these words from the IT team if you or your company is using an Mobile Device Management (MDM) application like VMWare AirWatch(older name) or UEM WorkspaceOne.

What does these applications do: They actually provide Mobile Device Management (MDM) service i.e they can manage millions of devices from one place. They can install Customer required applications, files to the device without any intervention required from the device user.
So essentially when a device is enrolled to such service like VMWare AirWatch, it allows the MDM service to access limited area of a phone. 

 [Please note that these services usually don't have any access to the user phonebook, users messages, phonecalls or any personal information. (Moreover, that would be against the Privacy Laws) ] . Once enrolled, a Corporate/Company/Organisation can send Enterprise related data to the devices necessary for their employees to function optimally at the workplace. The data or file , applications would be Enterprise Data and does not belong to user.
And if an employee leaves the Organisation, Organisation has all the rights to delete Enterprise Data and set the device free for user if the device/phone is BYOD(Bring Your Own Device). In this case, The admin of MDM service provider would initiate Enterprise Wipe command.

Enterprise Wipe: 

An enterprise wipe unenrolls the device from MDM service and strips off all enterprise content, including email accounts, VPN settings, Wi-Fi profiles, secure content, and enterprise applications. In this case, Device does not reboot once the Enterprise Wipe is completed. In short, it deletes or removes selective data owned by the company without deleting everything or deleting user data.

Enterprise Reset:

ER enables you to reset a device similar to an enterprise wipe, but with one important difference. Applications,Profiles and files/actions which are set to persist on a device are not removed and automatically get reinstalled on a device following the first reboot after an enterprise reset. Device gets automatically re-enrolled as it was earlier. Its available only on Zebra and Motorola, Honeywell Rugged devices. Consumer devices like Samsung, LG does not usually support this feature. This feature would be used when you want to factory reset the device but you still want to keep the data that was there before resetting.

In Short, Enterprise reset will factory reset your device but will persist the MDM enrollment.

Device Wipe:

Device wipe essentially means - Wiping the Device. A Device Wipe reboots the device and removes all data ( includes all personal user information ), email, profiles and MDM capabilities and the phone returns to a factory default state. Its same as that of doing a Factory Reset to your phone from Settings > Personal > Factory Reset.

Once the device is wiped old data on the phone OR the data before enrollment does not exist on the device due to factory reset. Usually, corporate dedicated devices are wiped so that they can be given to the new user.

Please note, device does not actually means a phone. Here, a Device can be a Android Phone, iPhone, Mac systems, Windows systems, Rugged devices.

Update:
Google has come up with new model called A4W/AFW (Android For Work). If you have enrolled your device with Android for Work (Android Enterprise) then on sending the Enterprise Wipe command would un-enroll the MDM agent from the device and performs Factory Reset which would delete everything from the device and makes a device clean like out of box.
Furthermore, there are different enrollment types when you enroll device to MDM in modes like  DA (Device Admin) , AFW - DO (Device Owner), AFW - PO Profile Owner i.e Work Profile , COPE (Corporate Owned Personally enabled), EWP (Enhanced Work Profie)
If you need to understand more about the Work Managed Device and Work Profile Device. You can check here

Update 2.0:

Google now has recommended to their partners to push down the companies and customer to move away from Legacy Device Admin mode. 

Update 3.0:

With all above still available, Google has come one up AMAPI (Android Management API) which is Cloud Platform API from Google that can integrate Google Android UEM functions with different EMM Clients. In Android Enterprise Setup, you can enable the Android Management API framework to manage Android Enterprise devices without the need to have a client app to be installed on the devices for device management. Refer: https://developers.google.com/android/management for more info.

How to solve WIFI not working if WPA_supplicant.conf is modified or changed.

I ran into the problem one day when I was just playing around my Android phone's wpa_supplicant.conf file.
I happily rooted my phone and went to /data/misc/wifi folder and edited the file using root explorer and saved it. Till this point it was all looking so easy. I rebooted my phone and I was surprised after the phone came back from boot.
My Wifi was not at all switching On after replacing the wpa_supplicant.conf file.
Tried many things but did not solve the issue. I was going to factory reset my phone but after long search
 I found the solution to WIFI not working.

The reason was, when we edit the wpa_supplicant.conf file while saving the ownership to file changes, as we will be editing the file as a root.


You can see from the screenshot, the ownername and ownergroup are changed to "root" instead, they should be "wifi"

Below are simple steps to resolve wifi not working:

$ adb root
$ adb -d shell

# cd /data/misc/wifi
# chown system.wifi wpa_supplicant.conf
# reboot

Speed-up your Chrome Browser to load page faster

As you may know, Chrome is one of the popular browser available to us and it is also among the fastest browser. You also might have used it or maybe you are using it now as well and can feel the difference of speed compared to other Web Browsers.
The fact which you might not know is, Google Chrome uses DNS prefetching and speedy (SPDY) protocols instead of HTTP. DNS prefetching and SPDY protocols helps to load the webpage in advance which reduces the time to load the page.
If you are reading this page means something went wrong with your Chrome browser. After using it for many days it tends to slow down. Lately, it has been observed that Chrom has been consuming high amount of RAM even if there is only one tab opened. Offcourse, it does lot in background so consuming high memory is not a surprise.

So, here are the things which you can do to fasten your Chrome Browser application for your desktop machine. This should work for other browsers too.

1. DISABLE THE  PLUGINS or ADD-ONS 

Having many plugins enabled in your browser can slow down it easily as it consumes time to load each and every plugin and moreover it consumes you RAM usage as well. So the best option would be to load the important plugin which you really need and disable the rest. I presonally prefer running zero plugins.
This is how you can disable it.


a. Open Chrome Browser and enter the following address into address bar

chrome://plugins/

b. Now you can Un-tick all the plugins which you think are not at all useful to you.
Please do remember that few plugins like Adobe Flash is required for many websites to display content so you should not disable it and there are some other plug-ins which can help your browser to increase performance.

2. DISABLE EXTENSIONS

a. Open Chrome Browser and enter the following address into address bar

 chrome://extensions/

OR

Click on Wrench icon on your toolbar > Tools > Extensions.

b. Un-tick the extensions which are not needed or can be deleted as well if not required.

3. CLEAR YOUR BROWSING DATA

Browsing data consumes good amount of space. Everytime you visit a webpage, some amount of data from the webpage will be saved on your system so that when you visit the same page again, the data can be loaded quickly. But if your not clearing your browser data, the data continues to increase thus slowing down your browser.

Although cache and cookies are really made to speed up chrome browser but sometimes it happens that they are responsible for decreasing your browsing speed and lagging while opening webpages.


This is how you can clear the data

a. Click on Wrench icon
b. Go to Tools > Clear browsing data.
c. Choose Time range in the dialog box and click on "Clear browsing data"

OR

a. Go to Settings
b. Search for "Clear browsing data"
c. And appropriately select the data that needs to be cleared.

4. Disable any ToolBar you have added to your Browser

Toolbars are your worst enemy. They stay on your browser and do nothing. Toolbars can really slow down the system and the browser. Moreover, I feel toolbars should not be installed at first place.

The Above tips works well for the other browser like FireFox and Internet Explorer as well. Only the path to change the settings will vary.

Hope you like the tips shared. Please do add any other tips if you have in comments.

You can set the Chrome to Dark mode . Check it out here

Make your Mobile phone camera a Webcam

During this Corona virus Pandemic (Covid19), people have been asked to work for home and you will feel the need of having a webcam some or the other day. Teleconferencing gets easier when you see the other person face to face rather than having the voice converstation.
Not everyone has a laptop and not everyone has a Desktop PC with a Webcam. Now a days, not having a camera/webcamera is a big deal. Attending Zoom Calls,Skype Calls, Facebook Live streams and many other applications and website demands you to have a webcam.
When I say a webcam , its just a camera which can stream you over internet, hence the name 'web camera' aka webcam.

So, here I am going to tell you about a simple application that I have tried and tested to make your mobile phone as webcam and save money.
As I am talking about Skype video call, I think I should call this post of mine as "How to use Mobile phone as a webcam"


IP WEBCAM
This one is simple yet elegant application which you can install on your android phone from the Play Store.
IP Webcam turns your phone into a network camera with multiple viewing options. View your camera on any platform with VLC player or web browser. Stream video inside WiFi network without internet access.


Features include:
• Video can be uploaded directly to Dropbox, SFTP, FTP and Email using Filoader plugin
• Several web renderers to choose from: Flash, Javascript or built-in
• Video recording in WebM, MOV, MKV or MPEG4 (on Android 4.1+)
• Audio streaming in wav, opus and AAC (AAC requires Android 4.1+)
• Motion detection with sound trigger, Tasker integration.
• Date, time and battery level video overlay.
• Sensor data acquisition with online web graphing.
• Videochat support (video stream only for Windows and Linux via an universal MJPEG video streaming driver)
• Cloud push notifications on motion and sound, cloud recording for motion-triggered records, online video broadcasting powered by Ivideon.
• Extensive baby and pet monitor features: night vision, motion detection, sound detection.

Here is the link for IP WEBCAM. Install the app on your smartphone and Launch it.
There are plenty of things which are there in the mobile app, which you don't need to worry about.

Next Step is to Download the configuration software.
Download from https://ip-webcam.appspot.com/

After installing the PC app and launching it, below screen will be shown
Click on Auto Detect.



If everything works fine, the camera will be available in Windows software. If something is wrong, please check your firewall rules and your network by visiting your network camera in a web browser.

Try restarting your PC if it does not work.
After restart, launch any application
say Skype and you can then configure your skype with the IP Cam.
In Skype, Go to Tools - Options - Video Settings .
Here You need to choose, MJPEG Camera
And Baam!!! all done.

You can see your pretty cat over your PC by using your phone.

In the similar way, you can config any Streaming application . You just need to use MJPEG camera as a webcam source.

Another App I remember which you can use is, 

DroidCam. It also has mobile app and a PC connectivity software.

In here you will find all sorts of sound effects, historical speeches, nature sounds, music, classic radio shows, video game quotes, movie and TV quotes, science quotes and more.

You can use these as inspiration to make audio loops.
They are also pretty interesting to simply browse around & listen.

Here is one more post which will remind you, Not to let the mobile phone battery discharge completely.
In fact, this habit of fully charging mobile batteries was considered pretty good with the older Nickel-Cadmium (NiCd) batteries. This is because of something called the Memory effect, which essentially causes them to lose their maximum energy capacity if they are repeatedly being charged after only partial discharges.

But now every phone is coming with Lithium-ion (Li-ion) batteries which no longer has such issue.

So, there is no point in charging and discharging them completely every single time and if you do this may account in reduction of the battery’s efficiency.

So below are some efficient practices for charging of Li-ion batteries :

• The 40–80% rule: Try maintaining the charge range in between 40%-80% in order to prolong the battery life to maximum.
• Even if you do charge it to 100%, never leave it plugged in i.e do not overcharge your battery
• Try keeping the phones in cool environment, as heat drastically degrades the performance of Li-ion batteries
• Fully discharge it once a month, as this helps in rejuvenating the battery’s accuracy of estimating the remaining time for complete discharge.

Above points hold good for your Laptop or any other device if its using Lithium-ion batteries

There was a post which I had posted recently about "Ok Google" where all the list of quick tricks were mentioned about how to use your smartphone smartly :)

But, Imagine Google itself giving a set of tips and tricks to make your android phone work efficiently and seamlessly, it has happened.
 I was going through android.com and landed up on a page which actually tells about the tips.
There are all sort of tips presented for Camera, Battery , Customization, Security with the simple to follow steps.

You can refer all of them at
https://www.android.com/phones/tips/

Requirement

Enable USB debugging on your smartphone .
(For that developer option should be enabled)

2nd thing you need is, adb drivers install on you pc.
Incase you dont have, google is the answer ;)


Now here the tricks starts.
You need to install Vysor on your Chrome Browser.
Download it from here 

Then install Vysor app from Google play on you phone.

Once all installations are done, you are ready to go.
Connect your smartphone to Computer to proceed for playing PokemonGO.

The moment you connect the phone, Vysor app will get installed on you phone too(in case you did not install)

The screen of your phone will appear on your computer .
You can then open the Pokémon GO app on the phone.
You will see it played in a window on your monitor.

Now you can wait for Pokemon to come to you and you can easily catch them using mouse instead of dragging your fingers on your mobile screen
And its easy for you to do multi tasking, you can use your computer and can play in between.

If your mobile screen goes off, and you have a new Pokemon near you,  the phone will vibrate and letting you know that , its time to Catch'em all.

How to Test your Headphone and Speaker

Found a  nice Audio testing Website which I wanted to share with you all.


There are plenty of Audio test files which you can directly run over your browser and then you can put your Headphones or Speaker to test.

Record Actions performed on your Android phone Screen


Say, you want to record the screen of your android phone i.e you want to record what actions did you perform. Its very simple.

Pre-requiste for this trick would be:
You must have an adb tool (it comes with android SDK)
You can get the tool by going through this page.

Open command prompt
Type below command and press Enter

adb shell screenrecord /sdcard/<filename>.mp4

That's all you need to do. Till this above command is running, all the actions performed over your android phone will be recorded in the path you have specified (in this case, /sdcard folder)
To stop recording stop the above command by pressing Ctrl+C.
You can play the video made with any player supporting mp4 format.

If you want to pull the file onto your system , you need to type

adb pull /sdcard/<filename>.mp4 <DestinationPathonSystem>

How to Charge mobile faster

Recently I came across with an nice android app called "Ampere".
Yes, it displays the current flowing into your mobile i.e while charging and also the amount of current being consumed by your smartphone while discharging.
With this app running on my mobile, I ran an small experiment.


Here are my observations,

Scenario	Charging or Not	Min Current	Max Current
Laptop - USB long cable	Laptop charging	770mA	840mA
Laptop - USB long cable	On battery	750mA	780mA
Laptop - USB Short Cable	On battery	1150mA	1180mA
Laptop - USB Short Cable	Laptop charging	1150mA	1180mA

The same goes when charging using the chargers.

With long USB cable the charging current was 890mA and with short USB cable it was 1460mA.

Charger rating was Input--0.6A, Output -- 6V- 2000mA

Its clearly seen,there is difference of 400mA  and that's a bummer if you use long USB cable.

It can be easily concluded from above table as well that using Short USB cable to charge will definitely decrease the  charging time i.e will charge your mobile or another device quicker.

And also, it does not  matter whether your laptop is charging or not the power being drawn from the USB port of laptop remains almost same.

You can also download the app from here Ampere Android app
and can understand how fast your mobile is charging with the cable you have or do you need to replace your usb charging cable.
