Network connectivity Issues

Tightly said

But samsung not caring for us

Provide feedback to samsung developers via feedback section(ask questions section), they need a minimum no. Of feedback from unique users (respect to no. of sales of device across all platforms), to add a premium feature. To provide feedback in samsung members app, Open Samsung Members Application > Get help > Send Feedback > Ask questions. If you want quicker action, write on every channel, whatsapp, samsung members app - ask question and error report, ceo escalation desk, service head desk, call toll free no. , support email of samsung, youtube, samsung content help( google it),samsung live chat,twitter, instagram,facebook,linkedin,etc. It is the power of our feedbacks only , that samsung started to give clipboard in many devices.

Continue giving, we got clipboard and samsung pay mini, we also take ca from Samsung.
