Hi. After replacing the battery, the camera does not remember the date and time settings. The problem is a dead super capacitor on the board. Original be used XH414HG-IV01E 3.3V 0.08F, in Czech Republic not to be ordered, I use M3R3703T01U 0.07F. Now the camera remember the settings. I be sad that the camera have a problem with touch screen and slow Wi-Fi, and a lot of small bugs in Firmware.
