The release of the iPhone 4S instead of the iPhone 5 may give chances to competitors – smartphones based on Windows Phone and Android from Microsoft, HTC, Samsung Electronics and Nokia, which will increase their market shares due to more innovative devices.

According to a study by InMobi, 41% of mobile phone users in North America (USA, Canada and Mexico) plan to purchase an iPhone 5 this fall, while half of them are going to do so within the next six months.

According to a recent report by IDC, Apple’s iPad has increased its share of the global tablet market from 66% in the first quarter of this year to 68% in the second quarter. In the same period, the share of Android devices from Google fell from 34% to 27%. RIM gained 5% market share in the second quarter, which was the debut for its new PlayBook tablet.

In March, IDC published forecasts for 2015 for mobile platforms, suggesting that Windows Phone will take second place in the market, Android will remain in first place, and Symbian will almost be forgotten. Recently, another research company, Gartner, also awarded Windows Phone second place in its forecasts for 2015.

According to analysts, sales of Android-based mobile apps will soon overtake the Apple App Store. However, according to other forecasts, the dominance of piracy and malware can finally convince developers that it is impossible to make money on Android applications.

According to analysts’ forecasts, the mobile games sector will develop most rapidly.
