What features to choose in a smartphone ?
People always tend to get confused what features to choose in a smartphone. Don’t worry we will help you out in this.
- TFT (Thin Film Transistor)
- IPS LCD (In-Place Liquid Crystal Display)
- OLED (Organic Light Emitting Diode)
- AMOLED (Active Matrix Light Emitting Diode
- Super AMOLED (Advanced version of AMOLED)
- Tactile/Haptic Touchscreen
- Retina Display
TFT LCDs are the most common type used in the phone manufacturing whereas IPS LCD are much better than TFT LCD as they have more viewing angle than TFT.
LCD are of two types: Capacitive Touchscreen LCD and Resistive touchscreen LCD.
Capacitive touchscreen are more better than Resistive touchscreen as they are more responsive to touch and are used in high-end smartphones.
OLED displays are much better than LCDs as they are lighter, produce great color sharpness, wider viewing angles and have very fast response time.
Retina display is IPS LCD with backlit LED used in Apple Products like iPhone 4, iPhone 4S onwards and iPad series.
Gorilla Glass is not a display screen but it’s a glass covering which forms protective covering over the display screen. Gorilla glass have proved its strength over various factors and it’s a high priority choice for every mobile manufacturing company .
Screen Size is a major factor while buying a smartphone . The basic law goes like this : Bigger is better !
Choose the best display type and the ample size as per your requirements.
Another factor is PPI(Pixels Per Inch). It is pixel density of a display screen. More the pixel density, more the sharp and better image quality of the phone.
It’s a choice to be made. Some phone manufacturing companies provide physical buttons in their products and some provide capacitive buttons .
Physical buttons can be touched and felt like a normal button whereas capacitive button are more like touching a surface of area with pre-determined function.
Processor is the most important factor while buying a smartphone. This is the core reason for fast working of any gadget.
Processor speed is measured in Hertz. Smartphones with higher MHz(Mega Hertz) or GHz (Giga Hertz) processing speed is better. Currently 1.2 GHz is normal speed of smartphones while high-end smartphones have up to 2.3 GHz and upwards.
RAM (Random Access Memory) is the memory where most of the application runs for temporary time interval. It’s a volatile memory i.e. it goes empty as soon as electric power goes off.
The basic rule about RAM is , ‘ More is Better ‘ . RAM above 1Gb is better for normal smartphones.RAM helps in faster indexing of files and folders.
ROM( Read Only Memory) is the memory where you store the App setup files, Music tracks,videos,documents,files. It serves the purpose of storing data.
ROM is of two types : Internal Memory & External Memory.
Internal Memory can be of 2GB , 4GB , 32GB , 64GB , 128GB or more.( The actual memory that you would get to access will be less than the stated values as the device use some of the memory.)
External memory is the memory which you can extend by adding memory cards and external memory devices. It can be 256 MB, 1GB and upwards.
The rule is same for the Memory : ‘ Bigger is Better ‘
Yes , even smartphones can have graphic drivers and GPU(Graphic Processing Unit).
The function of this unit in smartphones is to help faster image processing instead of using CPU for rendering images.
GPU is that special embedded circuit which comes into scenario where high-graphic Games and high-end softwares are used.
Everybody knows why a battery is important in any gadget . Well , the battery is measured in mAh(Milli Ampere Hour). The battery these days have 1400 mAh and upwards for low-end smartphones. High end smartphones may have batteries of 2300 mAh or more. The battery rating matters if you need better longevity of the phone running. Everybody loves their phone to run for a longer time without charging it multiple times, so , choose a smartphone with high mAh rating.
Connectivity in terms of phone sharing its files and apps within a specific range of the phone can be categorized as follows.
WiFi is used to connect to the Internet via Wi-Fi hotspots. Smartphones can transmit 802.11b and 802.11g at 2.4GHz whereas WiFi with 802.11a can transmit at 5GHz.
Bluetooth is short range communication for sending files. Bluetooth version 2.0 is common and Latest Bluetooth version 4.0 is found in high-end phones.
NFC( Near Field Communication) uses electromagnetic radio fields instead of radio transmission like Bluetooth and Wi-Fi. This technology is the latest technology involved in latest smartphones.
Infrared technology is an old technology used for transmission of files. It requires direct line of sight and is a very short range way of communication.
Whether you are a selfie addict or a photography enthusiast , you need a better camera in your smartphone. Samrtphones have a wide range of camera lenses and digital optical technology involved.
There are two types of camera in smartphones: Primary Camera & Secondary Camera
Primary camera is the Rear Camera or Back Camera as termed in normal language.
Primary camera used to be a VGA camera but in normal smartphones it is around 2Mpx(Mega pixels) and upwards. High end smartphones have cameras ranging 8Mpx, 13Mpx and upwards.
Secondary Camera is the Front Camera which comes in some of the handsets. Some manufacturers give secondary camera in some high end smartphones so that you don’t have to turn your phone around and take pictures .Thus ,you can switch to secondary camera and snap pictures directly.
You should also opt for Camera Flash if available in any model.
Warranty is the term for assurance,servicing,free repairing by the manufacturers as per their criterion. Sometimes there are unwanted problems in the handsets which are not specified by the phone companies and these can be resolved by the companies within their terms and conditions within a certain time period. This time period is usually around 3 months , 6 months, 1 year or any Time interval as per the company’s Terms.
While buying a smartphone, you should definitely check for long time warranties and their terms for sales/servicing. A Warranty can save your money in case of faulty handsets .
Extended warranty also is effective in terms of customer satisfaction.
There are many OS(Operating System) in the market right now and many are being rolled out every year. The OS is the main Software which interfaces with Hardware to create a user friendly response. You might get confused what an OS is ,so checkout the examples below.
Examples of OS :
- Windows Phone
- Firefox OS
- Sailfish OS
- Blackberry (QNX)
A smartphone cannot run without an OS.Choice of OS is up to you because it depends on user experience, fast responses, app support, design flexibility, developer support and many other factors.
Grab a smartphone having an OS which suits your usability.
Cost is the biggest factor in buying any thing. The rule is simple , high-end specs or phone with high quality , high capacity parts and softwares would be costly. You should buy a phone which suits your budget as per your requirements from the above points.
The customer is the king in any economy and you are the sole individual whose reviews would be helpful for others helping them to buy a product or not.
Check the customer reviews before buying any smartphone as well as check top reviewer’s review on particular brand.
