The start-up process is very slow and in the middle, the speed automatically changes into EDGE signal even if the settings are on manual. What to do?
The client switches to EDGE because that's the signal emitted in your area or this could be a filter imposed by the company from where you acquired the device. Many companies choose to limit the speed and connection of their users/customers when they reach a certain amount of traffic data. One possible fix is to reinstall the application and use its default settings without tampering any other options during the install process.
