Is the security software in Android a scam?

Q. Is LookOut security software in Android is a scam? I heard in the reviews that some said it's a scam and it's difficult to remove., is that true? What is the best, safe, and effective security software for my Android 2.3?

A. Android is the most popular mobile OS in addition to iOS at the moment, but it�s one of the most insecure platform as well. A case in point is San Francisco based software vendor Coverity released a report last year saying that there were a huge number of bugs in Android kernel, among which 88 are high-risk defects. The latest is called Auth Token bug, security researchers have found that in Android 2.3.3 and earlier version there is an Auth Token leakage. When the user log onto a Wi-Fi network using Client Login, the Auth Token contains unencrypted password can be obtained by the hackers easily which put user private data at risk including Google Calendar, Google contacts, Twitter and Facebook account.

So it�s absolutely necessary for Android users to install security apps to protect their sensitive data. However, there are a wide range of them � some better than others, and all come with different feature. Here we introduce some best yet free security apps for Android phones.

Webroot Mobile Security Basic

Webroot is very popular among Android users. It comes in both paid and free versions. Paid version has more features, however their free versions covers some of the basic capabilitiy like block and remove malicious apps, protect contacts and passwords, call and SMS blocking and secure web browsing etc.

Lookout Mobile Security

Lookout is committed to mobile security, their security app for android lets you backup and restore your private data so you do not have to worry that any of them goes missing. It also scans your Android phone for malware to keep them out of your phone. In the meantime, Lookout releases a mobile lost and found app called Plan B. If you read my blog often, you will remember I introduced it in my previous post. Basically you can install it to your Android Smartphone and show its location on Google Maps.

Lookout mobile security comes in two versions, free and premium. Generally, the free version provides the basic security service for your phone and in most cases it�s good enough. You do not need to upgrade to the paid version until you need extra features.


What is the difference between "rooted" and "Unrooted"?
Q. I have a Virgin Mobile Optimus V and it's an android. I know that rooting is the same concept of jailbreaking an iPod, or an iPhone.

But specifically, what do you get with rooting your phone compared to not rooting it?

A. when u have rooted your phone,

a)you can remove the system apps which came preinstalled in your phone
b)u can overclock your cpu.,,,, lg optimus has 600mhz processor which overclocked upto 806mhz
c)u can access various android system files
d)you can install new kernels in your optimus v,,i.e if you install the mik-os kernel, then the cpu spike problem can be removed(when playing games the phone lags when u touch the screen)

e)by rooting, you can install various custom ROMS(android versions) in your device.,,,android gingerbread 2.3 versions are also available,,,,check out the xda-developers forum


What does Android phones have that others don't?
Q. It has apps, that's one thing I know but tell me, are all apps free? What kind of apps are there? Tell me what they come with and what it has in the phone already. Basically tell me everything you know about it. I want to buy one from virgin mobile, do I have to pay extra just because it's an android? Thanks :)

A. Android is an operating system that was launched by Google about a little less than 7 years ago.
Android is now the leading OS in smart phones market share,android is running on 38% of all existing smart phones,while the second is IOS and running on 27% of all smart phones.
U can find the page with all these statistics at the source.

Now,Android itself is running on Linux kernel (which is something involving computer OSs,so let's not go further deep into that),and that is actually an advantage because the linux kernel is open source and any system running on the linux kernel is open source which means that the user or the developer can change anything with the system files or adjust the kernel itself or any part of the system he'd like to change,all in order to deliver better performance,and that's why android versions are too many and the roms for each android phone are almost endless.

Android is mainly considered the best smart phone OS out there because u can customize anything with the screens and the launchers so that u can do things faster,better and more efficiently while using the phone.

Android has tones and tones of apps (latest statistic records that the android market has over 300,000 app with an average daily growth of 63+ apps),and android apps are very useful to anyone for every day life,u can use them to do anything,such as alarms,agenda,remotely control your pc or laptop,play music and videos,download movies,music files and documents,browse the internet on-the-go,and pretty much evertything u can do with your mac pr pc and even more than that,just on the go and at the palms of your hands.

If u doubt that you'll actually like android or if it's the best choice out there for you,then you shouldn't worry,as almost 400 million android users can't be wrong.
U can try the OS before buying any phone running android,these are the options available to you:
1-U can test drive any android phone at any carrier store;like AT&T,T-mobile,vodafone and others.

2-U can buy an entry-level android phone like,which is a name for cheap phones that yet feature all the goodies of android,like: HTC Wildfire,HTC Wildfire S,Vodafone 845,Vodafone 858 Smart.

U can check the source links for the android market share statistics and all the info about android at the second link.

P.S:this answer was "copied" from another question (answered by me as well),with a little addition this time,if u want to see the original answer,then it's the third link at the source.
Hope I've helped.


Why isn't there any other distributions for mobile devices besides android Android?
Q. Android is an open source distribution based off of the Linux kernel. In the world of Linux there open source policy allows people to create thousands of distributions such as Ubuntu, Debian, Fedora, etc. So what is stopping people from doing this with Android?

A. There are, there was Moblin, Maemo, Meego (Forked from Moblin and Maemo)

There is Openmoko Linux, Tizen (Forked from Megoo), Jolla (The new Meego).

There are some others, though I have not kept up with them.

Oh... and there are some Android forks as well, i.e., the Military hardened version of Android http://gizmodo.com/5882546/us-military-to-get-secure-android-handsets & Open Android http://code.google.com/p/open-android-alliance/ and some others http://news.yahoo.com/three-android-forks-exist-today-135000744.html

Will the newest invisiblek kernel work on a stock rooted HTC Incredible?
Q. I really like this kernel and like the stock Android 2.2 interface but is it possible to use this kernel without a custom rom? It says it works on Asop so is stock 2.2 asop?

A. I cant speak for the Kernel but yes ASOP is another name for a stock android with out any custom UIs such as SENSE or TouchWiz


Pretty sure the Incredible is NOT an ASOP device as it comes with Sense UI

How long does it take to compile android?

Q. ICS and later. I set up a VMware machine with access to 8GB of RAM (I got a total of 16GB) and access to 4 out of 4 cores and 50GB of HDD space.

How long will it take to compile android + a kernel?

A. Depends entirely on the power of your system. Which you didn't really include. You included how many cores - but not what type, and not the speed of your hard drive... both of which are important bottlenecks.


what does it mean when a tablet is OS?
Q. I just bought a tablet and I'm trying to identify it. All i know about it is that when it turns on it says "android tablet kernel OS" what does that mean? Please help.

A. It means that the operating system installed on the tablet is an Android-related OS.


What is the contact information for the manufacturing company of an Android 2.2 Tablet PC?
Q. I bought an Android Tablet 2.2
Kernel version: 2.6.32.6 jade@linux-server2 #207
Build number: V2.061
My tablet is not working correctly. The touch screen is not sensitive, you have to repeatedly pound the screen. And it WILL NOT charge. The red light stays on, and if you unplug it, it immediately goes black. Who do I contact or what do i do?

A.


Can an android tablet be booted from a usb port?
Q. I was wondering if I can run one of those light weight linux distro installed on a usb flash drive on one of those android tablets.
1) Is there a cheap tablet PC (under $200) that can be booted from a usb port?
3) Can I find a lightweight linux distro that has all the drivers for that tablet?
Thanks for replying.

A. First of all, Android is Linux. It's a custom Linux kernel with a special software layer on top. And the customizations to the kernel and the software layer sitting on top of it are pretty important for it to run on the rather specialized smartphone architecture.

Second, a kernel has to be compiled to run on a certain architecture. So you'd have to find a version of Linux compiled for an ARM processor. That's not much of a problem. Several distributions, including Ubuntu, have ARM kernels. But then you'd have to have kernel modules for the drivers of the smartphone hardware, which... isn't nearly as likely. And you'd probably need a specially-designed interface, since Gnome or KDE really wouldn't work on a 4-inch touchscreen. And all of that would also have to be specially compiled for the kernel. And that's before we start with the application software. And by the time you got all of that working... you'd essentially have Android.

And even if you could do all of that, you'd have to have some way of booting from the USB, which you can't since smartphone firmware boots the kernel directly, without any sort of bootloader like you have on a personal computer.

If you want Android to be more Linux-y -- whatever that means, since the Linux experience differs greatly based on the graphical interface (assuming you use one) -- you can install a terminal emulator and even the bash shell. If you play around with it a bit, you might be able to install some command-line Linux software. But even then, it wouldn't be terribly useful, given the limited ability to enter text on a smartphone.

How can I optimize my battery life on a rooted android phone?
Q. i recently rooted my phone, and now i want to improve its battery life. what are all the possible ways i can do this?
i underclocked it but i want to know if i can do more. i also heard you can do it involving kernels, if so how and which kernel?

A.


Does anyone know how to connect a flashdrive to a android phone?
Q. I have an android LG Optimus Slider (virgin mobile). and it would be vary useful if i could use my flashdrives with it so if anyone knows what apps/programs i would need or the hardware hook up. i have no problem with making some sort of adapter for the data port on the phone i just need to know how. or if anyone knows where i could buy some sort of adapter. and would i need to root my phone. all help appreciated

A. The easiest way to start is to grab a USB OTG adapter. If you can't (or don't want to get one), find a female USB A --> microUSB cable. On this cable, open the microUSB side of the adapter and solder pins 4 and 5 of the microUSB port together.
When you have your USB OTG adapter (or modified microUSB cable) you can then run the commands to load the necessary kernel drivers. Everything here is already on the rooted PlayBook, so you won't need any extra files. The commands are as follows:

slay RIM_usbmgr-Winchester
slay io-usb
slay devb-umass
sleep 2
RIM_usbmgr-Winchester -m0s
io-usb -domap4430-mg ioport=0x4a0ab000,irq=124
sleep 2
waitfor /dev/io-usb/io-usb 4
devb-umass cam pnp blk automount=+hd6t6:/accounts/1000/shared/usb:dos,automount=+hd6:/accounts/1000/shared/usb:dos

The only line you really need to pay attention to is the last one as it shows where the flash drive will be mounted after it's connected. You can specify different mount points for different partitions by separating them with comas (in the example here hd6t6 and hd6 are shown).
for more queries you can go through a website http://www.learnmax.co.in/android-training.html ,hope you wil get your solution.

Q. I am interested in developing google android apps and i am from india, but in google i could learn that in india, android apps applications cannot be sold or used? What should i do now?

A. Many of andriod applications are free software and the base system of andriod is also free software (linux kernel) so applications can be developed freely. Assuming you know how to write programs you can develop applications for it freely. This is the android developers site http://developer.android.com/index.html
