A feature phone is a mobile phone that retains the form factor of earlier-generation phones, with button-based input and a small display. Feature phones are sometimes called dumbphones in contrast with touch-input smartphones.[1] They tend to use an embedded operating system with a small and simple graphical user interface, unlike large and complex general-purpose mobile operating systems like Android or iOS. Feature phones typically provide voice calling and text messaging functionality as well as basic multimedia and Internet capabilities and other services offered by the user's wireless service provider. Feature phones have a backlit LCD screen, a hardware notification LED, and micro USB port and have a physical keyboard, a microphone, SD card slot, a rear-facing camera to record video and capture pictures, and GPS. Some feature phones include a rudimentary app store that include basic software such as mobile games, calendar and calculator programs.

Prior to the popularity of smartphones

Prior to the popularity of smartphones, the term 'feature phone' was often used on high-end phones with assorted functions for retail customers, developed at the advent of 3G networks, which allowed sufficient bandwidth for these capabilities.[2] Feature phones were typically mid-range devices, between basic phones on the low end with few or no features beyond basic dialing and messaging, and business-oriented smartphones on the high end. The best-selling feature phones include those by Nokia, the Razr by Motorola, the multimedia-enabled Sony Ericsson W580i, and the LG Black Label Series that targeted retail customers.

 i Phone 11
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.
All in all, the iPhone 11 is an unexpectedly compelling upgrade, thanks largely to the significantly improved low-light camera performance. If you have your eyes set on last year's iPhone XR, spend a little bit extra and get this one instead.

How to fix/solve Presentation Error

What is “ Presentation Error ”? As you start participating in coding competitions, you are fully acknowledged with most of the errors which generally occurs during the program. What to do if you’re facing an error that doesn’t usually occurs i.e., a special type of error known as “ Presentation Error ”. These errors may occurs due to the following factors: 1)   If there is wrong formatting from your side, the answer seems to be correct but the online judge doesn’t identifies it. 2)   If an output results to an integer but you’re   presenting it in the form of string, then it may be a serious issue. For e.g., the program OUTPUT should be 15.76 ASSUME THAT WE HAVE THE FOLLOWING JAVA CODE SNIPPET : . . String ans="15.76"; System.out.println(ans);        //gives a presentation error . . float correct_form=Float.valueOf(ans); System.out.printf("%.2f",...

How to fix/solve Compilation Error in Python

A Quick Overview on Compilation Error A Compilation Error is a special type of error that occurs while using Python as Source Code. The main reason behind this error is that python is an interpreted language. So, the online judge rather than interpreting it compiles the code and hence the error occurs. The best approach to tackle these kind of problems is either use a compilation command or convert the program in single line using the single function containing the whole program For.e.g., Program to convert a character in LowerCase at a specified place. def mains():                    //Driver Function     n,K=input().split()     n=int(n)     K=int(K)     S=input()     print(S[:(K-1)]+chr(ord(S[K-1])+32)+S[(K):]) mains() Input: 4 3 TEAM Output: TEaM Hope this articles ...
