I just want to make a few observations of what I have experienced after the 4.3 update. I cannot successfully connect to WiFi networks following the update due to a "weak signal". I also could not recharge my battery using a wireless connection due to overheating and no change in the charging status (not a problem previously). I also have noticed that my flash will discharge for no apparent reason periodically. While I understand that with updates there are unforeseen issues, I want to give my personal observations. I look forward to a fix as no WiFi means I am using a lot of data.
