- Vibration on the phone does not work at all nor keypad vibrations
- The speaker where you place your ear for a call has a lot of static when on the phone and the volume is low even on max and with volume mods
- the back facing speaker is low even with volume mods on high
- the continuos bad reception it has
- notifications that the sim card has been removed when it has not
So what I'm trying to ask is if i reflash stock 4.3 on it and set the flash counter back to 0 with triangle away, can i call customer service complain that the phone has all these problems and that knox was already broken when sent to me so I can get another galaxy s4 sent to me?
