VIM3 Android Pie V200103 ROM Release

yes, I understand you, maybe Terry can give more information, contact him directly

by the way, WiFi is turned on by default, turn it off, maybe it gives obstacles

Its been turned off, unfortunately, still not working. @Terry Hi, Im new here :slight_smile: Was going to buy a bulk order of your boards, but this issue is holding me back at the moment. Do you have any info regarding this 4G issue? Should it be working or is there some fix in progress? Thanks!


You can try to flash the new firmware, I updated the 4G module support.


Thank you! Did test with new firmware, but no difference. I have set connection type to automatic and get 3G icon in status bar, service provider is listed correctly, but no data is being transmitted. Tested with your supplied antenna and also different manufacturers of antennas. Connected to M and D connector on 4G module.

When booting into android, I get the message “Phone Services” “Lost mobile data connection. Data roaming is turned off, tap to activate” I switch roaming on but still no data connection." Not sure why it asks for me to turn on roaming when all specs tells me it should work fine in my location. After reboot, leaving the notification alone, it disappears after some time and says connected to 4G with the name of teleprovider present. Still no data connection. One more edit :slight_smile: When network type is set to 4G (preferred) it displays 4G connection. Choosing 3G as network instead of 4G leads to device to go to 3G roaming. Still no data. Selecting Access Point Names under Mobile Network crashes the settings page and jumps out to desktop.
