Iphone vs Samsung Galaxy

Which phones are better: iPhone or Samsung Galaxy


iphone vs samsung


See, first of all they have different OS (Operating System). iPhone runs on ios whereas Samsung runs Android but even then I will write about the aspects which are important to be known before buying one of these beasts.

These are two different species of smartphones. Each has its pros and cons. The user should decide what suits best for their requirements.

Apple iPhone 

  • Pros :
    • Betters hardware and build quality : Your iPhone will function the same way it did when you bought it maybe a couple of years. It won’t have any issues until Apple decides to update it to an iOS version which will make it so slow that you would want to replace it!
    • Security : Being a closed environment and proprietor OS iOS/iPhone is considered to be more secure than Android when your data is concerned.
    • Apple Eco-system : For those who use apple products like iPhone, MacBook, iPad, etc. Apple offers great syncing capabilities. If you are working on one device and want to switch to another apple device, its all synced up. Great!
    • Status Symbol : Owning an iPhone is a status symbol (at least it was an year ago or so). People take great pride in showing off the iPhone and the Apple logo - even the cases have a cut out to show the logo.

  • Cons:
    • Price : The iPhones are way costlier than what features it offers. This holds true for buying unlocked iPhones in countries like India. They newly launched iPhone with base version starts at about INR 60,000/- and above.
    • Restrictions in hardware : What is a pro is also a con in this case. Apple offer fixed storage space for iPhones (SD card expansion not allowed)
      Apple charges too much amount for an iPhone with larger storage capacity.
    • Lack of customization : The iOS does not have any scope customization. The layout is almost the same since inception.
      You cannot add themes or change the look of your home screen or icons in an iPhone.
    • Lack of freedom to connectivity : You cannot tranfer files over Bluetooth from an iPhone to another smartphone. It has to be iPhone to iPhone transfer.
      You cannot see the ‘Filesystem’ in an iPhone. Each app will have its own space shared inside and you cannot manage your space as you do in Android.
    • iTunes : This is the mandatory software you must have in your PC or MacBook to sync content from your computer to iPhone.
      You cannot just plug your iPhone into a PC and use it as a mass storage device as you can do with Android.

Samsung Galaxy 


Samsung phones come with advantage and freedom of Android OS.
All cons of iPhone are Pros for Samsung devices.
For those who complain about TouchWhiz - that was true till past couple of years. The Samsung UI from Android 6 is far more refined, fast and has almost no bloatware to slow it down.
Samsung Makes amazing Displays - the Super AMOLED displays are the best for viewing photos and videos on your phone.
Samsung phones are affordable. Anyone can get a Samsung phone starting at INR 8,000/- only and it goes up to INR 70,000/- for the Flagship S8 (for 2017)
So a large number of people have access to and can buy Samsung phones as opposed to iPhone which can be purchased only at higher costs. The cheapest iPhone today is iPhone 5S (16GB) which is a 4 year old device.

So, one should consider the above facts and go for the brand which suits best for their needs and financial capabilities. 


" All depends on what you want your phone to do with your phone. If you want to customize your phone by changing many of the factory settings such a screen colors and changing the look of icons etc. Samsung is your phone.
 On the other hand if you want to get a more secure phone that does not allow you to customize your phone Apple has got to be your phone. Apple is the most secure phone in the world because of this simple fact that apple will not allow anyone into there operating system and as such receives far fewer hacks than any other phone on the market. 
Another security point worth considering is that Apple’s App Store vets all developers software thoroughly before allowing their particular apps to be offered for sale through there store, hence you are 99% percent sure that you will not buy an insecure app. On the other hand the Google Store (for Android Apps) does not implement this procedure, and hence apps could be allowed on their store that introduce malware, viruses or ransomware onto your phone.
 Another of Apples big selling points is that they will never sell any of your personal details on to anyone, this can be proven when no less than the FBI were not allowed access to the San Bernardino Bombers phone with Apple refusing to assist them in this matter because of their stringent privacy policy. Unfortunately by Samsung allowing you to customize  your phone this opens up back doors that hackers will find and use.
 It is also worth mentioning that Samsung don't use their own Operating System instead they chose to use Android which is an open source operating system which means the code can be altered. There is a fine line between allowing customization of the phone at the same time keeping your phones and tablets secure. 
I am not saying that Samsung phones are a bad phone they are excellent as are Apple phones in fact their is very little to choose between them when comparing quality. I personally use an Apple phone and iPad because I have the view that security is the number one feature in a phone or tablet, on the other hand many people would argue that their number one priority is the ability to customize their Phones. 
Everyone is entitled to their own choice. Putting security to one side there are other differences between the two, Apple design their own hardware and their own operating system, the only manufacturer in the world to do so. Apple phones/tablets components are specifically designed to work with each other hence you achieve such things as better RAM memory management, as per example an iphone with 4MB of memory will still run faster than a Samsung phone with 8MB of memory.
 This is because Samsung design their own hardware (which is excellent) but use an off the shelf operating system (Android) as do almost all other phone manufacturers. Subsequently the hardware and the operating system are not designed to specifically work with each other. It is a rarity for an Apple phone to get a virus or such, so much so that it becomes big news if that happens and virtually impossible to get a virus on an iPad because the hardware is built in sections, one section not being allowed into another this stops he propagation of a virus to infect all the other sections within the phone. 
Comparing like for like they both sell at around the same price so that need not come into the equation. Samsung have released their 2019 phones already but we shall have to wait for Apple to release theirs to compare the latest 2019 phones. To conclude both manufacture excellent phones, to me it is a simple decision Security or Customization "

    Windows vs Linux

    Linux vs Windows: What's the Difference?

    Windows Vs. Linux:

    WindowsLinux
    Windows uses different data drives like C: D: E to stored files and folders.Unix/Linux uses a tree like a hierarchical file system.
    Windows has different drives like C: D: EThere are no drives in Linux
    Hard drives, CD-ROMs, printers are considered as devicesPeripherals like hard drives, CD-ROMs, printers are also considered files in Linux/Unix
    There are 4 types of user account types 1) Administrator, 2) Standard, 3) Child, 4) GuestThere are 3 types of user account types 1) Regular, 2) Root and 3) Service Account
    Administrator user has all administrative privileges of computers.Root user is the super user and has all administrative privileges.
    In Windows, you cannot have 2 files with the same name in the same folderLinux file naming convention is case sensitive. Thus, sample and SAMPLE are 2 different files in Linux/Unix operating system.
    In windows, My Documents is default home directory.For every user /home/username directory is created which is called his home directory.

    KEY DIFFERENCE

    • Linux is an open source operating system so user can change source code as per requirement whereas Windows OS is a commercial operating system so user doesn’t have access to source code.
    • Linux is very well secure as it is easy to detect bugs and fix whereas Windows has a huge user base, so it becomes a target of hackers to attack windows system.
    • Linux runs faster even with older hardware whereas windows are slower compared to Linux.
    • Linux peripherals like hard drives, CD-ROMs, printers are considered files whereas Windows, hard drives, CD-ROMs, printers are considered as devices
    • Linux files are ordered in a tree structure starting with the root directory whereas in Windows, files are stored in folders on different data drives like C: D: E:
    • In Linux you can have 2 files with the same name in the same directory while in Windows, you cannot have 2 files with the same name in the same folder.
    • In Linux you would find the system and program files in different directories whereas in Windows, system and program files are usually saved in C: drive.

    Windows Vs. Linux File System

    In Microsoft Windows, files are stored in folders on different data drives like C: D: E:
    But, in Linux, files are ordered in a tree structure starting with the root directory.
    windows and linux file system
    This root directory can be considered as the start of the file system, and it further branches out various other sub directories. The root is denoted with a forward slash '/'.
    Types of Files
    In Linux  everything is a file. Directories are files, files are files, and devices like Printer, mouse, keyboard etc.are files.
    Let's look into the File types in more detail.

    General Files

    General Files also called as Ordinary files. They can contain image, video, program or simply text. They can be in ASCII or a Binary format. These are the most commonly used files by Linux Users.

    Directory Files

    These files are a warehouse for other file types. You can have a directory file within a directory (sub-directory).You can take them as 'Folders' found in Windows operating system.

    Device Files:

    In MS Windows, devices like Printers, CD-ROM, and hard drives are represented as drive letters like G: H:. In Linux, there are represented as files.For example, if the first SATA hard drive had three primary partitions, they would be named and numbered as /dev/sda1, /dev/sda2 and /dev/sda3.
    Note: All device files reside in the directory /dev/
    All the above file types (including devices) have permissions, which allow a user to read, edit or execute (run) them. This is a powerful Linux/Unix feature. Access restrictions can be applied for different kinds of users, by changing permissions.

    Windows Vs. Linux: Users

    There are 3 types of users in Linux.
    1. Regular
    2. Administrative(root)
    3. Service

    Regular User

    A regular user account is created for you when you install Ubuntu on your system. All your files and folders are stored in /home/ which is your home directory. As a regular user, you do not have access to directories of other users.

    Root User

    Other than your regular account another user account called root is created at the time of installation. The root account is a superuser who can access restricted files, install software and has administrative privileges. Whenever you want to install software, make changes to system files or perform any administrative task on Linux; you need to log in as a root user. Otherwise, for general tasks like playing music and browsing the internet, you can use your regular account.

    Service user

    Linux is widely used as a Server Operating System. Services such as Apache, Squid, email, etc. have their own individual service accounts.  Having service accounts increases the security of your computer. Linux can allow or deny access to various resources depending on the service.
    Note:
    1. You will not see service accounts in Ubuntu Desktop version.
    2. Regular accounts are called standard accounts in Ubuntu Desktop
    In Windows, there are 4 types of user account types.
    1. Administrator
    2. Standard
    3. Child
    4. Guest

    Windows Vs. Linux: HOME Directory

    For every user in Linux, a directory is created as /home/
    Consider, a regular user account "Tom". He can store his personal files and directories in the directory "/home/tom". He can't save files outside his user directory and does not have access to directories of other users. For instance, he cannot access directory "/home/jerry" of another user account"Jerry".
    The concept is similar to C:\Documents and Settings in Windows.
    When you boot the Linux operating system, your user directory (from the above example /home/tom) is the default working directory. Hence the directory "/home/tom is also called the Home directory which is a misnomer.
    The working directory can be changed using some commands which we will learn later.

    Windows Vs. Linux: Other Directories

    In Windows, System and Program files are usually saved in C: drive. But, in Linux, you would find the system and program files in different directories. For example, the boot files are stored in the /boot directory, and program and software files can be found under /bin, device files in /dev.

    iPhone 11 Summary



    The iPhone 11 is a successor to the iPhone XR and the name represents a reset in Apple's naming strategy to emphasise that this is the "default" iPhone for everyone. Powered by Apple's own A13 Bionic chip, the iPhone 11 trio are the fastest smartphones you can buy today, with the closest competition at the time of filing this review being last year's iPhone lineup.
    Perhaps the biggest improvements are in the camera department, achieved by both software and hardware changes. On the rear, you get Wide and Ultra Wide 12-megapixel cameras that produce excellent image quality in nearly all situations. Night Mode makes Apple competitive in low-light photography, and then some, which means the iPhone can finally compete favourably with offerings from Google, Samsung, and Huawei when it comes to night-time shots.
    Just like the iPhone XR, this phone will offer you all-day battery life and iOS brings with it the promise of timely updates, something most Android OEMs falter with even today. However, it's not a perfect phone.
    The screen is the same low-resolution panel that we saw last year, and Apple continues to bundle a 5W charger with the phone, which is just appalling. While the former is something most people won't notice thanks to the panel's excellent colour accuracy and brightness, the latter is a pain point you will need to live with every day, unless you decide to buy a faster charger separately.
