Really disappointed with the 4.3 update, I expected better from Google. Not feature wise, but testing and stability wise.
First the bug with Netflix locking up the phone, and today I discovered that my Nexus 4 now suddenly refuses to charge via USB when it's switched on.
With the power off, it charges fine. As soon as it's switched on, nothing. "Charging" briefly appears for a fraction of a second, then disappears, and the phone doesn't charge.
A quick Google search has revealed at least a few others having this issue - it can apparently be solved by using the official micro USB cable, but I only have one of those, at home, and wanted to charge the phone at work.
I've been using a Samsung micro USB cable because the official one doesn't seem to be available anywhere (I haven't checked the Play store, because last time I did their charges were ridiculous, but it isn't on the usual sites like Amazon). Until the update, that Samsung cable worked perfectly. Now, it suddenly doesn't.
Not impressed to be honest.
Edit: Found a workaround for the USB charging problem online - if anyone is having the same issue, when the phone is plugged in to USB go to Settings - > Storage - > Menu - > USB computer connection. Then untick MTP and/or PTP. Exit the menu and then unplug & replug your USB cable. The phone should charge then.
