Sometimes I will completely lose my data connection on this phone and when I go Quick Settings I noticed that the "Mobile Network" check box will be unchecked and greyed out so I can't even re-check it to enable the mobile network. This has happened several times randomly and I know that I'm not accidentally unchecking the Mobile Network box. A power cycle will fix the problem but I shouldn't be forced to do multiple power cycles every day.
I'm also having the phone constantly switch from 3G to 1X to no data at all while my phone sits in the same spot on my desk.
I've tried *#*#4636#*#* and *22899 and ##778 and nothing has fixed the issue. I've also enabled data roaming.
Any suggestions?
