In a recent report, Stockholm student Jazz Johnson revealed a handy backspace feature on the Apple calculator app, which let users swipe backward to erase a wrongly entered number, instead of starting over again. After making his discovery, Jazz made a quick demo showing that iPhone users can just simply swipe left or right to correct a wrongly entered number instead of starting over.

It seems the capability is not very well known to many yet and took to Twitter to share their surprise. According to a source, one Apple user posted: "After all those times I had to clear the entire thing."  A video demonstrating a little-known feature on the iPhone calculator has proven a major hit with Apple users. It appears that plenty of Apple users were completely unaware of the app's swipe functionality and instead of hitting the C key and totally resetting a sum whenever you mistype a number. It's a straightforward bit of functionality that will come in handy the next time Apple users sort out their monthly bills. Moreover, a Twitter user, who goes by the name CENSORED dialogues, posted also a video showing off the swipe functionality which has been in existence on iPhones since the last five years but remain uknown until the latest discovery.

On the other note, Apple this week reported a surprise decrease in iPhone sales for the quarter ending 1st of April, having sold 50.76 million of the handsets during the three-month period. Some analysts believe this is because customers are delaying buying a new device, due to the much-awaited launch of the tenth-anniversary edition iPhone.

However, recent reports claim these prospective customers may have to wait longer than they might expect for the new iPhone.Though the upcoming iPhone is believed to be unveiled in September, mass production might only start to kick off in October, and it may only end up becoming widely available at the beginning of 2018.
