- Brand (optional)
- Price
- Specifications (very important)
The first thing that should be removed from the mind before buying a smartphone is the smartphone brand. Actually most smartphone companies make smartphones from flexible approach. That means, any smartphone brand. But the camera will be from Sony, the AMOLED display will be Samsung. And Google's Android and processor make a smartphone from a company. In such a situation, while buying a smartphone, the attention should be paid to the specifications rather than focusing on the brand of the smartphone.
Before buying a mobile phone, you should decide your budget, how much price (price) you are able to buy a mobile phone because it can categorized yourself and you will get help in selecting the best phone.
Example: If you have to buy a mobile phone from 10 thousand to 12 thousand, then in case you have fixed your budget, then you will only have to review the review, specification and brand of the phone of 10 - 12 thousand.
Specification is the most important when buying a phone, so when buying a phone, only the specification should be paid attention. The specification will decide whether the phone is good or bad.
After deciding the budget, you will have to decide for what purpose you want to buy the phone (excluding features like phone calls, messages, emails).Such as photography (camera), video recording (rear & front), gaming, internet, storage, etc., you can select one or all of these features.
- Display screen
- Processor
- Operating System
- Memory
- Camera
- Battery
If you buy a new smartphone, then you should first know about its screen size or resolution etc. in the specification. Because the better the screen, the better you can use it. There are many types of screens in mobile phones, so it is very important to know which screen is better for you?
Companies bring their smartphones with different displays according to the budget. Smartphones are available in the market in the same and different budgets equipped with different displays. Without being confused, today let's talk on the type (type) of the display. So that you have better knowledge about the display, priority of the display before purchasing the smartphone.
There are 5 types of mobile screen available in the market today :
- TFT-LCD
- IPS - LCD
- OLED
- AMOLED
- Super Amoled
Thin film transistor techniques were commonly used in LCD mobile phones. TFT LCDs offer decent image quality, high resolution. Their viewing angles are not as good. Also, it is not clearly visible under direct sunlight. Also, larger TFT displays consume more power and are not battery-friendly. But these are cheaper options, due to which companies prefer to give them in budget phones.
IPS refers to in-place switching. Common IPS LCDs are considered much better than TFT. View this display from any angle, everything will look clear. That is, viewing angles are better in them. Another feature is that IPS-LCD displays reduce battery consumption. Due to their presence in mobile, the battery life increases. Obviously these displays are costlier than TFT LCDs. Apart from this, colors appear more accurate in them.
At the same time, colors are not as punchy as compared to amoled screens. This is the reason that companies usually prefer these over expensive smartphones.
OLED stands for Organic Light Emitting Diodes. This is a new technology that is being used in mobile and monitor nowadays. It is technically filled with carbon-based organic material between 2 conducting sheets (cathode and anode). It is then closed from both sides. When an electric pulse is applied on both these sheets, light is produced from the filled conduction in the middle. The brightness and contrast of the display depend on the electric pulse. When comparing OLED to LCD, they are much better than them. Then it is about any aspect like color, response or brightness.
AMOLED stands for Active Matrix Organic Light Emitting Diode. It is also a variety of OLED display, which has caught pace. It is also given in expensive phones. Like the OLED, it is also a high quality display, which has attractive features like better color coordination, light weight, battery friendly. The most important feature of this display is that its blacks are deep. In black, the black color appears to be completely black. Apart from this, colors are quite punchy.
Recently Samsung has used this display in smartphones like A6 +, J6. Actually there is an advanced version of AMOLED, which Samsung has prepared in the name of 'Super AMOLED'. Actually, it is a version of the OLED display made by Samsung. By the way, some experts believe that Super AMOLED has more punchy colors than AMOLED.
- Capacitive touchscreen
- Resistive touchscreen
Capacitive touchscreen technology consists of a glass layer coated with transparent conductor. As soon as the capacitive touchscreen gets human touch, pressure is created.
It is a kind of electrostatic field and by this a change in capacitance is identified. It is then identified by the processor chip of a mobile. In the next process, it is passed on to the mobile software, so that the touch identities started working.
The resistive touchscreen has 2 layers with a conductive material in between. It acts like a resistance. When the finger is touched on this display, a circuit is made as soon as the touch is between the top and bottom, the material between them. This touch is identified by the processor chip of the mobile itself.
After passing from there it is identified by the operating system of the mobile. Resistive touchscreens are less responsive than capacitive touchscreens. It sometimes requires something like a stylus or a pen. This technology is no longer commonly used in smartphones. You can now find this screen in an ATM machine.
Often people are confused about which screen is good, LCD is good or Samsung's AMOLED. Actually, LCD display has more brightness. But the AMOLED panel saves battery. Also the colors look quite good in it. In such a situation, if you have to choose between LCD and AMOLOD, then AMOLED should always be selected.
To protect the screen, it is coated with a variety of techniques to prevent the phone from falling or from scratch in any manner. Apart from this, some techniques also protect the phone from getting dirty.
This technology manufactured by Aashi Glass Corporation prevents the screen from being damaged. This is a technique very similar to Corning Gorilla Glass. In this, a layer of hard and thin glass is used which protects the screen from rubbing and scratching.
Whenever talking about the screen of the phone, the safety of the screen in it is also important. In such a situation, the screen available in the phone nowadays is coated with Gorilla Glass. Gorilla glass is a type of aluminosilicate glass shield which is damage resistance. Using this, the display of the phone can be saved from scratch.
With this display, you can save your phone screen from getting dirty and dirty. Sometimes, when using the phone dirty and smooth hands, its screen becomes dirty. In such a situation, this problem can be avoided if the screen of your phone is covered with olio phobic coating.
Whenever it is about the screen or resolution of the phone, the screen size and its resolution are used in it. When you buy a phone, you often find that the screen resolution of the phone is obscured. But there are hardly any people who would know what the screen resolution is and which resolution is better for the phone display. So tell us that the display resolution of any phone, computer or mobile phone is the number of different pixels involved in its dimension.
Every image on the screen of a mobile phone is made up of many small dots called pixels. This pixel shows the clarity of the image in the phone. The higher the resolution of pixels in the phone screen, the clearer its screen will be. Screen resolution is usually measured based on width x height. For example, if the resolution of a phone's screen is 1024 × 768 pixels, it means that its width is 1024 pixels and height is 768 pixels.
- VGA: 640 × 480 pixels
- FWVGA: 854 × 480 pixels
- HD: 1360 × 768 pixels
- HD Plus: 1600 × 900 pixels
- Full HD: 1920 × 1080 pixels
- Quad HD: 1440 × 2560 pixels
- Ultra HD 4K: 3840 × 2160 pixels
The speed and level of tasking of any smartphone depends on the processor. Processor performance in Android World is usually estimated from the core. The more cores in Android phone's processor, the better the performance is likely to be. If there are more cores, then multitasking will be easier with their help, but there should also be suitable RAM.
Understand the need of the core in such a way that at one time you are playing games on your mobile, listening to songs and the download is also going on in the background. It would be extremely difficult for a single core processor to tackle so much work at once. Multi-core is useful in such a situation. In this way, dual core will always be better than single core.
Basically, a core is a unit or chip that performs a CPU (the computer's internal computation), a single core is called a single core processor. The power of the processor depends on the GHz (GHz), that is, the higher the processor the more GHz ( GHz).
Single core processors used to hang more and more, so to increase its capacity, additional cores (cores) are installed in the processor, based on their number, the names of the processors have to be known.
- One Core Meaning - Single Core Processor
- Two core means - Dual core processor
- Four core means - quad core processor
- Six core mean - hexa core processor
- Eight core mean - octa core processor
- Ten Cores Means - Deca Core Processors
For smartphones, companies like Snapdragon, Mediatek, Exynos (Samsung), Qualcomm and ARM Cortex are making processors, depending on your budget, considering the core (core) and Gigahertz (GHz) of the mobile processor (mobile processor) You can choose the smartphone as per your choice.
The processor is the life of the phone. In such a situation, the processor should be taken special care while buying the phone. Processors of companies like Qualcomm, Mediatek, Helio, Apple Bioni, Apple Bioni, Exynos are present in the market. But instead of the name of these processors, attention should be paid to the size of their chip. Explain that the smaller the chip size, the better will be its performance. The chip size is measured in nano meters. They come in sizes like 12nm, 8nm, 7nm, 5nm. It would be better to take a phone with 8nm or 7nm chipset instead of 12nm.If you are buying an expensive smartphone, then buying a smartphone with a 5nm chipset would be a better option. Apple's latest Apple A14 Bionic chip comes in 5nm size.
Among all these points, this point is most important because if you do not know the frequency of the processor of a mobile, then the speed of the processor will also not be known how many clock it works on in seconds. And the unit to measure its frequency is Hz (Hz), 1Ghz in the processor of a mobile means that it works for 1 second 100 million times. As these numbers increase, the speed of the processor increases
Some important points related to frequency that you should always remember:
- 1 MHz (Megahertz) = 1000000 Hz
- 1 GHz (Gigahertz ) = 1000000000 Hz
- 1 GHz (Gigahertz ) = 1000 MHz
- 1 GHz (Gigahertz ) = 1,000,000,000 cps
- 1 MHz (Megahertz) = 1000000 cps (cycle/second)
A mobile operating system (OS) is software that allows smartphones, personal digital assistant (PDA), tablet and other devices to run applications and programs.
A mobile OS is responsible for identifying and defining mobile device features and functions, including keypads, application synchronization, email, thumbwheel and text messaging.
A mobile OS is similar to a standard OS (like Windows, Linux, and Mac) but is relatively simple and light and primarily manages the wireless variations of local and broadband connections, mobile multimedia and various input methods.
The operating systems found on smartphones include Symbian OS, iPhone OS, RIM's BlackBerry, Windows Mobile, Palm WebOS, Android, and Maemo.
Android, WebOS, and Maemo are all derived from Linux. The iPhone OS originated from BSD and NeXTSTEP, which are related to Unix.
Android OS: The Android operating system is the most popular operating system today. It is a mobile OS based on the Linux Kernel and open-source software. The android operating system was developed by Google. The first Android device was launched in 2008.
iPhone OS / iOS: The iOS was developed by the Apple inc for the use on its device. The iOS operating system is the most popular operating system today. It is a very secure operating system. The iOS operating system is not available for any other mobiles.
BlackBerry OS: The BlackBerry operating system is a mobile operating system developed by Research In Motion (RIM). This operating system was designed specifically for BlackBerry handheld devices. This operating system is beneficial for the corporate users because it provides synchronization with Microsoft Exchange, Novell GroupWise email, Lotus Domino, and other business software when used with the BlackBerry Enterprise Server.
Windows Mobile OS: The window mobile OS is a mobile operating system that was developed by Microsoft. It was designed for the pocket PCs and smart mobiles
Bada (Samsung Electronics): Bada is a Samsung mobile operating system that was launched in 2010. The Samsung wave was the first mobile to use the bada operating system. The bada operating system offers many mobile features, such as 3-D graphics, application installation, and multipoint-touch.
Always buy the phone with the latest operating system. The two operating systems Android and iOS are generally more popular in the market. Android is from Google, whose latest version is Android 11. While iOS is Apple's operating system. IOS provides more security to the device than Android.
Phone's memory includes RAM and ROM. RAM equals the memory (or memory bar) of the computer, while ROM is the device's internal storage, equaling the hard disk of the computer.
The bigger the RAM, the more software the phone runs smoothly; While the bigger the ROM, the more data it can store. Usually, a phone with big RAM is not easy to get stuck. So far, the RAM of the smartphones generally reaches above 2G, the major phones are equipped with 3GB / 4GB, even 6GB and 8GB.
The two types of memory used in a mobile smart phone are as follows:
- RAM
- ROM
Memory where software resides while it is running, along with the data it is using. Both the OS and application software use RAM.
RAM is a type of memory that is very fast, but is volatile, meaning all information is lost when electric power is removed. For this reason, it is useful only for temporary storage of data that requires fast access.
A device will typically have RAM and some kind non-volatile memory to store a copy of all software and data that needs to be kept when the device is powered off, or while that specific software is not running.
Devices with more RAM can run more complex software and/or more applications at one time.
Moving data into and out of RAM takes time. If data needs to be moved out of RAM to make room for other data, this can bring everything to a halt for a moment. Therefore devices with more RAM are more likely to have RAM free when it's needed, which keeps everything running smoothly (faster).
ROM is a form of data storage. This type of memory keeps the saved data even if the device power is off.
The word Read-only identifies it as "read-only memory", since the reprogramming process is generally infrequent, comparatively slow, and often does not permit random access writes to individual memory locations.
It equals a hard disk in a computer, storing various of files, including videos, songs, photos, and system software, etc.
At present, most smartphones are equipped with 16GB, 32GB, 64GB, or even 128GB, 256GB large ROM.
But we have to pay attention that in phones the ROM is not described with ROM but with storage.
The way the phone has increased the needs of the people. In this case, more storage is required. Also, to run the app, too much internal storage is required. If you are buying a budget smartphone, then see that there is at least 64GB of storage. At the same time, 128GB storage becomes necessary for mid range smartphones and 256GB for flagship smartphones. If you play games on the phone or use more and more apps, then it would be better for you to get a smartphone with more RAM. In such a situation, 4GB to 6GB RAM is considered better for a budget smartphone. Up to 12GB RAM is supported in expensive phones.
The camera of the phone should not be chosen on the basis of more megapixels and more lenses. If this happens, then how a good photo can be clicked with a low megapixel iPhone. The guarantee of a good camera is not only more megapixels, but the camera's sensor size, aperture, shutter speed and the phone's processor make the phone's camera better. In such a situation, while taking the phone, all these things related to these cameras should also be taken care of.
The Battery due to more apps and more daily usage, it has become necessary to have a large battery in the phone. It is better to always choose a battery larger than 4000mAh in the phone. Now phones come with higher refresh rate, higher brightness and higher resolution, which consume more battery faster.
