The Internet Explorer doesn't shows my history and I can download anything either. What should I do ? I have a Microsoft Lumia 640 phone.
and I don't even have (or want) a Microsoft account in order to download any... and THAT too is part of the reason I'm leaving, I bought the phone, I shouldn't be forced to sign up for an account and use their servers/mail in order to download apps. With Android you do not have to shop through the official store nor do you need a Google account in order to download most apps from other apps stores.
I agree that IE seems poorly implemented in respect to do Windows Phone. However, it sends you failed to do research on the WP ecosystem. Since it is a Microsoft product, logically a Microsoft account is necessary for the app store. This is no different than using Google or Apple products and their respective app stores. Android is a far cry different from MS and Apple in respect that the source code is open source. Therefore there are open source third party app stores that you don't need an account. However even some Android third party app stores require accounts such as Amazon. Another factor you have neglected is the fact that Windows Phone has a very small market share in comparison to android or iOS. That is why app development has been limited.
