Contra
- During a telephone constantly hear noise and I've also extended dropouts. My interlocutor hears me bad - very quiet. Software repair attempts - no success! (Have the latest software on it). Changing the settings (microphone noise suppression and optimize voiceover) has brought nothing.
- On warm day (heat there was no) to shut the power off because of overheating, although I have received no 4K movies ... until now but only happened once and prior to the firmware update
Conclusion:
I will return the unit. It makes everything super except calls.
