So many problems with this one. WHY did T-Mobile not try this in BETA first? Aside from battery life which dropped even after several days use to about 60% of what it was before on my LG3, WI-FI phone connection is highly unreliable. Even though LG3 identifies a Wi-FI system, and signs in, the little phone symbol won't come up. Disconnect and connect. Turn phone on and off. Finally it connects. BUT THEN it disconnects and you never know it. So you miss calls, messages, etc. If you are in a fringe area and depend on WI-FI, or a building that has poor cell signals, or live high up in a high rise, you are screwed. You can't use your phone. Unless you check all the time that the little phone symbol is on the top line, and when it goes off, repeat everything... phone on and off. Disconnect reconnect to Wi FI system.. Makes MY cell service useless. Since update have missed many important calls, and it has cost me big bucks. SHAME SHAME SHAME on T-Mobile for allowing this update out and telling me to install it on my phone without first finding out in BETA that it does not work on the LG3. After 15 or more calls with T-Mobile IT support, doing a master reset, changing the SIMM card, and everything between, I bailed. No more LG3 for me. Real shame. It was a nice phone.
