Sadly, given that I can't look at your phone I can't trouble shoot it. And I find most folk loathe to pay for support.
I think that's wrong too.
I cannot access my GMail account on my Samsung mobile phone for several days now. I have never had a problem with this previously, and GMail always loaded promptly. Other email accounts, e.g. Yahoo Mail, load fine, & there is nothing wrong with my phone. Was on the phone with Verizon tech support for a long time, and they finally decided the problem is with GMail. But GMail offers no tech support whatsoever. Have found others complaining about the same problem in a GMail forum on Google, but no help has been forthcoming. Anyone know anything about this? I may have to cancel my GMail account if I can't get this problem fixed. Another example of what's wrong with Google??
