Updated my phone to VRUDMI1, which seems to have helped the WIFI, no doubt.
However, there is one annoying thing that has changed with the update. If you are on a call (speaker phone) on the call screen, and say you want to look something up on the web... Hit your home button, while in Speaker Phone, the top bar turns green as you are in a call. So, you browse the web and find what you are looking for, then you go back to pull the top menu bar down to go back to the call screen
Well, the screen turns black and times out as you are trying to swype the top menu bar down. You have have to swipe your hand over the screen 3-4 times to get the green bar to pull down without the screen turning off. Keep in mind, this is while on speaker phone. If I am on a Bluetooth call, or on my wired headset and I do the same thing, I have NO issue. Top bar pulls down easy and the screen never shuts off.
I am often on speakerphone then go to look at things on my phone and I can't get back to the call. This is super annoying and already am hating this. It never did this before.
For the record, I did a factory reset after the update and it did it before the RESET and Does it after the Reset. I am guessing this will stay until Android 4.3. I haven't seen anyone else comment on this change, but it sucks.
