I just did an update to my Droid 4 this morning. After that, I took some pictures from my phone, opened my gmail account, attached the pictures, and sent them to another gmail account. No problem- I received them. I did this again, 10 minutes later, and, there are no emails on the phone gmail accounts or on my home computer gmail accounts, or, anything indicating that I sent or received the email. I did this again, and, one hour later, nothing. I synched the gmail acounts and still nothing. Prior to today, there were times that I would send an email (using gmail) from the phone and did not receive the response on my home computer, but, it was there on my cell phone. Other times, I would send an email, and it did not show up as being sent on my phone, but did on my home computer. Please help- this last example was a time-sensitive email and this is not acceptable- I'm assuming that I'm doing something wrong- I can't tell you how many times I'm using the "synch" feature on this phone.
