The smartphone and tablet are well developed and being wide used in the world, however, there are still a lot of rooms for improvement.
1. Short battery life
Most of the smartphones and tablets cannot run for an entire day without charging. With the big screens and rapid quad-core processors of smartphone and tablet, they are always power hungry.(Mark Spoonauer,2014) Also, the batteries become thinner to shrink the size of modern tablets and smartphones which lead to short battery life. Nowadays, the smartphone and tablet do what the computer does. They check the app updates, receiving notifications of new email, social network updates. Even the screens are off , they are still running too.(Chris Hoffman,2013)
2. Crackable screen
The screen of smartphone and tablet are easy to appear scratch after using for few months because user’s finger nails scrape the screen . Also, they are easy to appear a big and conspicuous fissure if they had a hit. Many people use screen protecters on their smartphone or tablet to avoid the scratch to appear. However, the screen protector will change the experience of using the touch screen which means that the screen protector is not a good way to solve the problem.( Chris Hoffman,2014)
3. Low compatibility
Smartphone and Tablet is not user-friendly for typing because the character images on the keyboard of smartphone are too small and compare to these small character, the finger is too big to touch the character so it is usual to type inaccurately. Also, it is easy to type wrong because of the inaccurate contact.
