1. Automatic upgrade: If the battery level is greater than 30%, do not touch the screen when restarting. There will be two words "upgrade" next to the signal in the upper left corner, and then wait for about five minutes for automatic upgrade. 2. Manual upgrade: If the battery level is greater than 30%, click on remote upgrade in the settings, do not touch the screen, and it will automatically upgrade. Do not click upgrade within 5 minutes of booting up, as the backend will automatically query the version at this time.
If the device is not online, you can check it one by one as follows. 1. Try restarting the device first. If it still doesn't work after restarting, follow the steps below to troubleshoot. 2. Is the IMEI entered into the platform consistent with the actual IMEI of the device. (It is recommended to check the device IMEI in the device menu) 3. Check if the SIM card inserted into the device is in arrears, if it is shut down, and if a second real name authentication is required. 4. Whether the device displays a 4G signal and the data icon is normal (the icon with a diagonal bar represents abnormality) without any outstanding fees or shutdown 5. If the signal is not displayed, unplug and reinsert the SIM card, restart the device and check again. If the 4G signal still doesn't work despite normal display, find another SIM card, insert the device and restart to see if it works properly. If it works, it's a problem with the SIM card.
During the device entering power-saving mode, it cannot automatically update its positioning, and functional instructions cannot be executed in a timely manner. It needs to be set to normal mode before it can work normally according to instructions. Please make backups yourself!
If the device is located indoors or in an underground parking lot, it may result in the inability to search for GPS satellite signals, which are either WIFI signals or base station signals, leading to significant errors, which is a normal phenomenon. After the device moves outdoors or leaves an area with poor signal, it will automatically calibrate its position. As long as it is outdoors or in an open area, the error will not be significant.
The front of the device faces outward because there is a ceramic antenna on the front that receives signals. If the front is obstructed by metal, it will affect the normal use of the device.
