I bought my wife a D3400 for her birthday a couple of days ago. However since getting the camera it has been locking up intermittently.
Whilst using the camera the green light will come on and stay on, and then the camera becomes completely unresponsive. Pressing any of the buttons or switching it on or off don't make any difference.
Taking the battery out fixes the situation until the next time it happens. Everything else seems to be working fine, and the pictures save to the memory card (and transport to the iPhone via snapbridge).
The camera seems to be on the latest firmware, and we're using a decent memory card that was formatted with the camera (SanDisk Extreme 32 GB SDHC). The battery is also fully charged.
Has anybody had issues like this? Could a mistake using the camera cause the lock-up or does it sound like a technical issue with the camera? I am not sure what to try except maybe trying another memory card.
Thanks
