Some Lumia 730 users facing freezing issue while dialing or ending a call


Lumia 730Seems, some Lumia 730 users are facing issues with their devices , when they try to dial a number or end a call. The device freezes and won’t respond and seems the issue is with Mobile+Sim settings. There is a thread over Microsoft discussions, where many have voiced their issue.

Now, some of these users have reached to us and we certainly want to help them. Microsoft moderators have offered solutions which are generic like soft reset, hard reset or using Nokia software recovery tool, but seems the issue still comes back.

One user has solved this issue by putting manual APN settings and disabling Dual-Sim settings.

Hi kumar.
I put manual settings of apn in my phone and turned off the dual call sim settings in network +. Its been 6 days with no hanging issues. Please make sure both settings are fine. Hope to see a positive reply from you.

May be the above workaround helps some. Anyways, here hoping that Microsoft fixes it with upcoming firmware update.

    Dear Kamal,
    Thank you for reporting on this issue. Many 730 users are affected by the same problem. The screen shots they have uploaded match. Those who have complained of this have tried every combination changes possible in settings, hard resets, the software recovery tool – all for no avail. Many are now considering replacing the device or, more drastically, leaving Windows Phone (for what guarantee is there that the replacement will not be just the same? Or that MS will respond with just the same apathy?)

    It’s a shame.

    In the meantime, I’m happy to have discovered your site; it is a very helpful resource for windows users. Keep up the good work.

    Thank you

      P.S. Setting the APN manually does not solve it, nor does fiddling with WiFi settings.
