My iVooMi Me5 Smartphone runs on Android 7.0.
When I use WiFi internet, everything works fine related to Internet except Whatsapp.
Information (Data, Image, Video and Document) exchange on Whatsapp is delayed over WiFi Internet.
It works fine on Mobile Internet.
Moreover, I have other android devices (iBall BraceX1 tablet runs on Android 4.4.2 and Moto Tubo Edition3 runs on Android 6.0.1). There are no such issues on both android devices.
Please let me know, what I need to check for iVooMi Me5 (runs on Android 7.0)?
