Despite giving users a smooth experience, the poor in the app store has made it impossible for Windows Phone to compete against Android and iOS. However, in the past, Windows Phone had the opportunity to surpass Android.Regardless of the death of Windows Phone operating system for a while, Microsoft founder “Bill Gates” is still very regretful when talking about this operating system. Recently, at the DealBook conference that was organized by New York Time, the billionaire shared interesting information explaining the failure of Windows Phone.Bill Gates said that Windows Phone would have been able to become as popular as Android today, if Microsoft had not encountered the antitrust lawsuit in 2001.According to Bill Gate, “Microsoft was responsible for the monopoly behavior. If we hadn't gotten into that dispute, we'd have been able to focus on developing the mobile operating system. If that happened then you would now use Windows Phone instead of Android."Although the incident has gone for 18 years, Bill Gates still expressed his frustration that year, the US Department of Justice forced Microsoft to take full responsibility. That was the moment Andy Rubin and his colleagues at Android Inc. build Android operating system. Another unfortunate point, Microsoft also missed the opportunity to cooperate with Motorola for a Windows phone.He said: “We were only three months late before Motorola announced their choice, and then the faster person won in every game. Now no one here has heard about Windows Mobile even though it was once worth billions of dollars.”
