Problem making/receiving/disconnecting calls and p...

Question

I was looking for a new phone to replace my old Samsung Star, but I was unable to justify this expense. So, I saw Nokia Lumia 710 with it's GPS software and hardware as part of the package. Windows phone looks so beautiful that I just bought it last march, 23th.
Now, verifying this forum I realize that my problem, some how, exists since January in Europe. As many people here I have problems to end a call, but in my case the call never completes and when I try to disconnect Lumia just does nothing beyond show "disconnecting" forever. The only way to recover control is turning Lumia off.
Its true that my carrier has a very weak signal where I live (at my apartment), but my old Samsung at least make and receive calls. Some times I must move near to the window to have a better reception, but works. With Lumia, different from what I was expecting (a premium Nokia quality signal  - the best possible reception), some times just do not work! Some times people calls me and the phone do not ring. Some times I receive that screen offering me the opportunity to send a message like "I'm at a meeting" or something like that, but I do not have the opportunity to receive that call. This is very frequent since I bought this Nokia. Some times, when I make a call, Lumia pretend to call, pretend that the other person is connected, but, in fact, there is no calling sound. The phone remains mute all the time, there are no call. When I give up, I press "disconnect" and Lumia shows "disconnecting" but nothing happens. To recover phone control I must turn it off to try again. Once I was so angry that I press many buttons and Lumia freezes up completely and was needed to remove battery to turn off.
About GPS, that was my main excuse to expend a lot of money on a new phone: Nokia Lumia GPS is disappointing. Lumia GPS looks like loose satellite signals very frequently. I decided to make a comparison between my Lumia and my wife's iPad. Working totally offline, side by side at my wife's lap, while iPad was able to show immediately every turn I make, Lumia takes long time to realize that. In fact, most of time, Lumia just realize that I turn when I was reaching next corner. I'm using Nokia drive 2 and, in this test, since I don’t have a GPS software at iPad, I just leave Lumia and iPad with the map showing our position. I do not set a destination.
Finally, my last disappointment is about windows Phone and the “one account policy”. Really? They think people will be happy to give up from their messenger accounts or Xbox accounts to use Windows Phone? When I turn on my Lumia for the first time it asks me to enter or create a Microsoft account. I think about and I realize that I don’t want to add payment information to my very old Hotmail/messenger account, so, I create a new one. My mistake because soon I discover that Windows Phone do not let me choose a different account for Messenger or Xbox.
I call Nokia in Brazil to find a solution for my two main problems: making/receiving calls and the GPS performance. The only solution they can think about was reset my phone. I do that a few hours ago. This time I choose to enter my Messenger account to be able to chat with my friends, but, of course, I loose my Xbox id created with the other account.
“One account policy” is so “not smart” that is very hard to understand why they do that. The need to reset the device to choose another account is unbelievable. Mean while, with iPhone/iPad, to change accounts is so easy…
I will test my phone for the next few days to verify if reset solve all my problems, but right now I’m very disappointed.
(I hope you can understand my poor english).

Reset Lumia 710 do not solved my problem. I was forced to send the device to technical support. Even if they was unable to reproduce the problems I faced at home, they did a flash reset (or something) and now my phone always ring when people call and I can end calls without a problem. For now those problems disappeared.
