I recently, (APRIL 2020) had a Blackvue DR900S-2CH Dash Camera installed in my car. Everything about this device is quite good except it would fail to reliably connect to the cell phone WiFi. I quickly found the solution. I use an Android LGV30 phone. I went into the cell phone settings and chose Network & Internet portion settings. All I had to do was to turn Mobile Date Off. Then the BlackVue cell phone application held a solid connection when I chose the BLACKVUE WI-FI menu selection on my cell phone. I even drove around a while with my cell phone showing the live front dash camera signal.
Caution: I did find a possible problem with turning off Mobile Date. I drove over to Starbucks to buy a drink and I always pay using my cell phone Starbucks application in the phone. Every time I open the Starbucks cell phone application I must choose “Scan in store”, a small sub menu option. Pressing that small menu button then presents a new screen that the Starbucks people can scan to take money out of my account. It would not work. Was this because I turned off Mobile Data? Or did I loose Internet? I was forced to pay cash! If this happens to you, just turn Mobile Data back on.
Just to check other cell phone menu options out: I went into the sub menu of Mobile Data, after Network & Internet. By pressing on that menu selection, “Mobile data”, I found two sub menu items:
- Mobile: You can scroll down and view all the applications using mobile data. BlackVue is one of them. There are two on/off buttons you can choose. I turned on both Background data and Unrestricted data usage.
- Wi-Fi: You can scroll down and view all the applications using mobile data. BlackVue is one of them. There are two on/off buttons you can choose. I turned on both Background data and Unrestricted data usage.
- Special Access > Modify system settings: BlackVue showed “No” (I have no opinion for this setting except to say that it was set to “No”.
- Special Access > Wi-Fi Control > BlackVue “Allowed” Allow app to control Wi-Fi. It looks like you had better turn this on if not on already.
