New to the community, but felt I had to comment on the LG G3's signal issues. I upgraded from an htc one m7 3 days ago after a lot of research. All of the reviews I read didn't mention any reception issues, but a couple of forums did, I decided to give it a go and see (heart overruling head maybe). Right from the outset I loved everything about the phone except for one thing, yep - poor signal. With my htc I got full signal at home on 3G all of the time and 2 bars of signal at work on 3G,in my office I get 2 bars on 2g, with the G3 I got anything from no signal to 4 bars on 3G but it was going up and down even when I was sat with the phone in my hand. At work the same story anything from 0 to 2 bars (usually 0) and in my office no signal at all. I tried several times with the sim in my htc and the signal was brilliant. I spoke to LG and they told me to do a hard reset, I did this and it made no difference. So back to O2 in plymouth, I spoke to a guy called Ryan who was extremely helpful. He tried a new sim with no difference and then we tried a new phone too, all of the time the signal was jumping up and down all over the place when my partners nokia and his iphone had 3 to 4 bars of signal. In the end I decided to cancel my upgrade and keep using my htc until the issue is sorted. Not sure if it is a hardware or software problem, if it's software hopefully an update will appear and I will get a new phone , if it's hardware then I don't know what LG will be able to do. Such a shame that there appears to be a big issue. It's all nice having all of the others things on the phone but if it can't do the one thing that a phone is supposed to do, ie. reliably make phone calls then not a lot of point in having it. It all sounds a bit negative but hopefully LG will sort it and I will try again.
