I have 3 groups of Wyze Cam perfectly running until today. My Phone is Samsung Note 9 . In group 2, Wyze Cam V2 after I installed Sandisk 128GB micro SD cards, formatted them everything worked fine. Then one camera would not initialize and turn on. I tried turning all cameras on and off, rebooting phone, rebooting camera but to no avail. I tried removing SD card and re-initializing camera but kept getting message that phone location was not turned on. It was. I tried going through the process 6 times. Finally got past that error message but now it tells me that my WiFi is not accessible and to go to settings but with no specific info. WiFi is enabled and I recently added additional phones including the one I am having trouble with 2 weeks ago without any problems.
Any concrete suggestions since I am about to return the phone.
