Hi. I've got a problem with a Droid 3. GMS works fine but when I enable UMTS I get a very weak signal, around one bar. Mobile data sometimes-somewhat works but keeps disconnecting constantly. So it gives me a choice between terribly slow but reliable EDGE and fast but fussy 3G. Neither of them is a compelling option :/ It's not a carrier issue, other phones have full strength in the same area. Has someone here had a similar problem? Do you know of any solution?
