Recently bought a new phone MX4 pro.. Then change the new simcard with "U" which support LTE.

I realise that the signal drop only happen when i am in the office. No server network, cannot call out/in. There is one time it happened, i walk out from office with the phone to open space, automatically it connect and have strong line.

I check with colleague using Digi has strong line in office.

I flash the ROM with latest version, still same. Report to Digi and restart for me still same. Change SIM card with group 40 still same.
Don't know is Digi problem or the hardware problem.


Any Digi user also encounter this scenario totally cannot call and no network with other phone especially got 4g ?

U r digi technician or u really went there to test?
1st of all thanks...

The office is at enterprise 4. Level 4 BAT.

like this?


It is not like completely no line/network the moment i enter into the office
Is like after the phone idle for certain time/online music stream, then no connection.... call in also cannot, like exhausted. i would say sometimes 1 hour, sometimes 30 min, sometimes 3 hour... no certain one.
By the way, my colleague use iphone 5, whatsapp no problem. Mine like a deadphone. I even have the sms by 121 missed calls the moment my line connected.

Ya i know his iphone not connect to 4g.

If say no network or weak network, i dun bother much
But what frustrate me is signal also dun have cause cannot call out/in... That puzzle me.

Possible is my phone receiver not strong?

But Xda has almost non discussion on MX4 pro/Mx4.
