I would like to ask if there is a way to check if the fact that my internet connection is slow (with 3G and 3.5 I have 1 Mbs or even less, and it used to be 4-5), it's due to the provider or to a hardware problem of my phone. Unfortunately some days ago my phone felt to the ground (about 1 meter fly). I was believing it was intact, but I did the speedtest and I found low values.
