4. It Over heats!!!
This is serious problem for me, this is one issue in an android devices that scares the hell out of me.. Android heats cell phone often. However if you have a good cover on your cellphone you may feel less heat, but if without cover just put your cellphone on your cheek you will find what I mean.
5. Box of Malware On Google play store
I agree that Google play has some nice applications, and most can be downloaded and installed for free. Sorry to burst your bubble, it appears these applications uploaded on Playstore are susceptible to dangerous malware, somehow, someway, spammers & hackers have a way of putting malware on Google playstore. If you download 10 Applications a day, 6 will be substandard or malware, so be careful and see how to prevent Malware on Android.
