In addition to the "unstable wi-fi" messages, camera flashes, and delays in unlocking the phone, I now have multiple dropped calls each time I try to talk on my phone (S lll). I can't carry on a conversation this way. I am not due for upgrading until next Nov., so I need to find a fix for this. Is anyone else experiencing the dropped call issue and/or have suggestions on how to fix it? Thanks in advance.
