Friggin' had it with the Nexus 4 I've got. Many issues have been cropping up lately and it's pissing me off.
Dialing out to a number, I've experienced where I can't hear the opposite party. Rebooting the phone, and it works.
Some times, when receiving phone calls, the swipe to answer the phone call just does not work! The only thing that works is the power switch, which serves to mute the ring tone.
Again, rebooting the phone works.
Sooooo blooody annoyed with this phone! That's it. Saving up for an Xperia or Iphone.
