Top 9 Best Voice/Video Calling apps for Android phones

Image result for voice app
Most of the apps categories in Google Play Store are overcrowded by thousands of apps vying for attention but there are a few exceptions too. Voice/Video chatting (voice calling over internet) is one such category which has a very limited number of apps. And out of these apps (which have this special function – allowing users to actually “chat”), only a selected few are up to the mark in terms of voice calling quality and hassle-free performance. Voice calling over internet is just like network dependent phone calling, provided you have a reasonably fast internet connection (which most of us have these days). The only catch in these apps is that the app must be installed on both ends (caller and receiver) and both devices must be connected to internet for free calling. Anyway here are the top 9 apps for voice calling (over internet) on an Android phone/tablet –
Skype – is perhaps the most popular app in this category which allows you to make free voice and video calls (Skype to Skype) and cheap international mobile calls (Skype to any number). The best part of Skype is that its a cross platform app available for almost all mobile and desktop OS. You can get Skype free from Google Play
Official Google Voice app – Google Voice for Android is an impressive app with which you can send free text messages and make voice calls all over the world. Download Google Voice free from Play Store
Google Voice for Android
Google Voice
Line – Line is a relatively new entry in this category but in a short time it has become hugely popular especially among youngsters. Line has a feature-set almost similar to WhatsApp and WeChat plus the added advantage of free voice calling. Download Line free from Play Store
Viber – Viber is a popular, cross-platform messenger app allowing users to send free text messages, video messages and to make voice calls. You can get Viber from Google Play
Fring – Besides text chatting, Fring also allows free group voice calling (upto four persons at a time). Download from Google Play
Tango – Tango supports group voice calling (upto 50 persons) and video calling at a time. Get Tango from Google Play
ooVoo – is a video chatting app supporting voice and video calls (upto 12 persons at a time), photo and video sharing, text messaging. Download from Google Play
ooVoo video call app Android
ooVoo video call
ICQ – ICQ is a messenger app which also supports voice chatting. Download ICQ from Google Play
Kakao Talk – KakaoTalk is another WhatsApp alternative app supporting group chat, voice calling and photo/video/voice message sharing. Download from Google Play
So what’s your pick out of these? and do add any other app you know in this category which I missed here.

Solution to Blue Screen of Death on Startup / Reboot




When blues screen of death showed upon startup, like the picture below, it indicates faulty hardware installed on your computer. In many cases, blue screen of death is cause by a defective battery. It happened to me many times and I found out the battery is empty.  To fix your computer, you need to replace your battery. Open your computer case and then remove the battery by simply pushing the lock until the battery comes out itself.

How to Partition an External Hard Drive




All new disk drives, whether internal or external, require formatting and partitioning before they can be used. Disk partitioning is the process that takes a single hard disk drive and segments it into logical units. You can choose to keep the hard drive as a single volume, or you can create multiple logical volumes. In Windows, the Disk Management tool provides an easy way to create partitions and file system formats on new external hard drives. To access and use the tool, you must have administrative rights.

Alternative Method to Hide Files and Folders in Windows





It seems like people just can’t get enough of the how-to guides on creating hidden folders or locked folders in Windows. I’ve already written two guides on how to hide a folder, one by using a very simple built-in feature of Windows and another by using some Windows scripts. In the latter article, I also mentioned a free program that you can use called Folder Hide to completely remove a folder from visibility. Lastly, I’ve written about hiding an entire drive letter in Windows too.

How to Capture Still Images from a Video or DVD



Watching a DVD movie on your computer or a video you downloaded from your camera and wish you could capture a particular frame as a still image? By default in Windows, the only options you might have are to use PrintScreen or to use the CTRL + I shortcut in Windows Media Player 9 and 10.

Computer Tips and Tricks Everyone Should Know-MUST

 we’ve compiled some of the most handy computer tricks you might not be taking advantage of. Our ultimate goal is to help you become more productive by shaving valuable seconds off your workflow. Of course, you can always pass along these tips to your not-so-savvy friends and family members to help them become better PC users as well.
General Tricks

Windows hidden "god mode" folder Windows offers a centralized Control Panel for all of the OS settings, which makes it easy for users to tweak everything from desktop background to setting up a VPN. To enter this mode, create a new folder with this exact name (copy and paste it): God Mode.{ED7BA470-8E54-465E-825C-99712043E01C}. The folder icon will change to a Control Panel-style icon, and you will be able to jump in and change all kinds of settings. Note: Don't try this on Windows Vista 64-bit as it's known to cause a reboot loop.



Use Problem Steps Recorder This handy tool automatically records any mouse clicks and takes screenshots for you. If you need tech assistance with your computer, go to Run by typing Windows + R, and then type "psr." Use the tool and by the time you are finished, you can send this information, neatly compiled automatically, to the person helping you with the issue. It will make the process of finding the problem much easier for them, which means you will be able to get your system up and running faster.

Find/Delete large files wasting space A handy tool called WinDirStat (Windows Directory Statistics) can be used to easily find which files and folders are taking up the most space on your drive. From there, you can delete them and open up a ton of storage space.



Reduce the number of programs running at startup If your PC is taking too long to boot, it’s probably because you have far too many programs running at startup. Reducing this is easy, it will make your PC launch noticeably faster and lighter upon first load. To change the items running at startup, go to Run using the hotkey Windows key + R, and type "msconfig." A small window will appear (see the screenshot below), select the Startup tab. From here you will be able to turn off many startup programs, which can shave several seconds (or minutes) off your boot time. (Note Windows 8 has moved this functionality to the Task Manager). Try to make sure you research what you are turning off as some processes might be needed by third party programs or drivers you have installed.



Cloud backup important files If you’re working on a critical paper for school, work, or any other major project, make sure you are backing up the file not just locally. You can use services like Dropbox, Google Drive, or any of the other popular cloud storage solution which will do the legwork for you on the background. Of course, you can also throw the files on a thumb drive or external HDD just to be safe but backing up to the cloud can be done seamlessly which is twice the advantage.


Typing Tricks

Delete an entire word Instead of deleting a single letter, pressing CTRL + BKSP will delete the entire word behind the cursor. This makes deleting text quicker if you screw up a whole word.

Move Cursor to beginning of the next or previous word Moving the cursor around manually while typing is a great way to make your work take longer than it needs to. To speed of the process, move the cursor around with keyboard shortcuts. To move it to the beginning of the previous word, use CTRL + Left Arrow. To move it to the beginning of the next word, use CTRL + Right Arrow. In OS X you can accomplish the same using the Option key.

Making sub and superscript text If you need to make sub or superscript text (think exponents for superscript), press CTRL + = for subscript and CTRL + SHIFT + = for superscript.

Paste plain text of what was copied When you copy text from any source, programs will usually copy any formatting that comes with it. To paste this as plain text, press CTRL + Shift + V instead of the standard CTRL + V, and the system will paste unformatted text.
Note that many programs follow this parameter (Chrome, Firefox, etc.) but not all, particularly Microsoft programs like Word or Outlook. For those there's a few alternatives that go beyond copying and pasting in Notepad: 1) CTRL + ALT + V will show a 'paste special' dialog box. 2) CTRL + Spacebar will remove formatting in already pasted text. 3) Download Puretext and choose a hotkey to always paste plain text with it.


Keyboard Shortcuts

Copy only active window to clipboard Normally, the Print Screen key copies the entire display (or two displays if you got them), ALT + Print Screen only copies the currently active window to the clipboard. Whether taking a screenshot to diagnose a problem, or just because you want to show something to a friend, this will come in handy.

Fix those little mistakes Did you know you can undo almost any action? CTRL + Z is the ultimate hot key, and for sure you knew about it already, however note that undo doesn’t just apply to typing. If you accidentally delete or move a file, you can hit CTRL + Z to bring it right back to where it was. In Chrome and Firefox you can also undo closing a tab using CTRL + SHIFT + T.

Cycle through open windows Pressing ALT+TAB allows you to cycle through currently open windows. This makes switching back and forth between running processes quick and painless. If you want a more stylish method of cycling through open programs, Windows + TAB will do the job for you.

Interrupt all processes CTRL + ALT + Delete is one of the most common PC shortcuts, and one almost everyone is familiar with. The important thing to note is that it interrupts all processes, including the one that is bogging down your system, which can mean the difference between needing to restart or not.



Close the current program Typing ALT + F4 will close the program that is running. This is useful as it saves you time mousing over the "X" and clicking. People will often use this as a joke, telling you to press ALT + F4 to fix a problem. Don’t fall for it unless you want to close what you are doing.

Minimize all windows Sometimes you have a bunch of stuff running, and you want it all to go away so you can get to the desktop. Simply pressing Windows + D will minimize everything you have up, which will save you some time pressing the minimize button for each window. It should be noted that Windows + M offers similar functionality, but there is no undoing, so Windows + D is the more favorable approach.

Open the task manager directly If you want to bypass the interrupt that happens when pressing CTRL + ALT + DEL and jump right to the task manager, typing CTRL + Shift + ESC launches it directly.

Close the current window/tab Stick of moving all the way to that X button? Press CTRL + W and the current window will close. (Don’t do it now, or you will miss the rest of the tricks!)

Bring up the system information window This is so much quicker than digging this out the traditional way... Just press Windows + Pause/Break and the System Information panel will be ready to go. This might be the only use for the Pause/Break key you will ever find, so enjoy it!



Better multiple monitor control There are several useful keyboard shortcuts for controlling open windows on multiple monitors. Pressing the Windows Key + Arrow Keys will cause a window to quickly snap to each side of either monitor. Alternatively, hitting Shift + Windows Key + Arrows will cause the window to jump to the other monitor. Lastly, pressing Windows + P will allow you to quickly set up a second display or projector.


Web Browsing Tricks

Automatically add www. and .com to a URL You can shave off a couple of seconds typing in a URL by simply click CTRL + Enter after you type the name of the site. Need .net instead of .com, press CTRL + Shift + Enter instead.



Jump to address bar There are a number of ways to jump right to the address bar from anywhere in browser. Pressing CTRL + L, F6, and ALT + D all accomplish this goal.

Bring back a closed tab We covered this already, but it's super useful. Accidentally closed a tab? Simply press CTRL + Shift + T to reopen the most recently closed tab and get back to what you were doing.

Use private browsing The uses for not having cookies and history saved are obvious for certain activities, you know, like shopping for gifts on a shared computer (of course!). Pressing CTRL + Shift + N will launch a new private in Chrome, CTRL + Shift + P will do it in Firefox and Internet Explorer.



Cycle through open tabs Pressing CTRL + TAB while in a browser will flip between each one. This can be much faster than moving the mouse and clicking on a tab. CTRL + NUM (1, 2, 3, 4, n..) will also take you to certain tab in that numeric order.
File Management Tricks

Rename a file quickly Right-clicking and selecting rename is not very efficient. Instead, simply press F2 while a file is selected to change its name. To alter the name of another file, type TAB without deselecting the current file.

Rename files sequentially in Windows You actually don’t need to download any programs to perform a batch file rename in Windows. Instead, you can select all the files you want to change, right-click the first one in the list, select rename (or use F2), and type in the name. This will automatically change all the other files with the same root name with a suffix: (1), (2), and so on.



Select multiple files using the keyboard To select a bunch of files using your keyboard, you can press Shift + down arrow to select a single file or Shift + Page Down to select a large group of files at one time.
Security Tips

Run programs on an infected PC Often times, malware will prevent a computer from running certain programs. Changing the name of the .exe file can often override this. If that doesn’t work, changing the extension to .com is another useful alternative, and the program will still be able to run in spite of the extension change.

Read installers Even major programs can install toolbars and other unwanted pieces of software during installation. Take a few seconds to read each step to make sure you are not agreeing to install something other than the program you were actually seeking. Far too often people just push next over and over, and end up with a browser covered in various search bars that just aren't needed. In the worst of scenarios, these can have nefarious intentions.

Lock your computer if you get up Sick of your "friends" going onto your computer at work or home and posting things on your Facebook/Twitter page on your behalf? It’s certainly an annoyance, but an easy one to prevent. Windows + L will lock your system right away, requiring a password (if you've set one) to log in again.


Program-Specific Tricks

Photoshop: Drag the marquee without losing the ability to size it The marquee tool is, at its most basic level, designed for selecting a part of an image. It’s used constantly in Photoshop, and there is a handy trick many users miss. While dragging it around, you can press space, which will allow you to size it while moving it. This saves time by letting your perform two key functions at the same time.

Steam: Move games to another drive or partition By default, Steam installs all games to the same HDD or partition, but what happens if that fills up? The solution: download Steamtool Library Manager. It makes it easy to move games to another hard drive without messing with the functionality of Steam.



VLC: Fix unsynced audio and subtitles In the popular media player VLC, if your audio loses sync with the video or subtitles, there is an easy way to fix this. Simply pressing J or K will move the audio forward or backwards. Similarly, to sync the subtitles you can press H or G.



The combination of using these tips and tricks on a daily basis will most certainly make your computer life much more enjoyable, or at least more practical. And so, did you learn a thing or two that you didn't know before?
