I have recently upgraded my Nexus 4 to Android 5 but it appears to have had a degrading effect on my ability to get a 3g signal. I am frequently getting no internet connection even though the phone signal appears OK. Several times I have turned the airplane mode on and off and occasionally this seems to work but going home on the train, for several days now, I get no internet for most of my journey. This has only been a problem since the upgrade. Is it a coincidence and the network has been poor or has Android Lollipop made my phone rubbish?
Thanks for replying and sorry it has taken a couple of days to reply. There does seem to have been an improvement recently. Unfortunately it is not going to stop me leaving as I feel the lure of 4g calling.
