If the "network unstable" icon is displayed, that means that your device has lost connection to the game server. Overdox requires you to be connected to the network at all times.
This is to ensure the stability of the game and lower the inconveniences that you may experience while playing a real-time game. One case to note is that there may be a situation where your Wi-Fi or carrier service may show full bars, but your network connection is unstable. If this is the case, you may experience delay, disconnection, or the "network unstable" icon may show up. For a stable gaming environment, we recommend that you play with Wi-Fi provided by your internet service provider or use 3G/4G network.
Also, to prevent combat being interfered by network disconnection, please try following the next steps. Reset/restart your mobile network connection or your Wi-Fi modem. Refrain from closing or leaving Overdox while you're in combat. Disconnect the Bluetooth devices connected to your mobile device and turn off the Bluetooth option.
Bluetooth devices may interfere with wireless signals. Be sure your device doesn't download new updates or start data synchronization. Close the apps running on the background. Try lowering the devices connected to your Wi-Fi. If you run into a network issue while playing the game, try switching to a different network. We recommend switching between Wi-Fi and 3G/4G network.
