I am using a Le Pro 3 WEXNAOP5802101261S firmware version. My current phone is the 3G connectivity issues. I'm always on data connection (3G, 4G) and Wi-Fi, however, when left overnight, when the phone is turned off wifi will not automatically connect to data.
To reconnect me to toggle airplane mode.
Please show me how to fix it.
Sorry for my english is not good.
Thank you very much.
