Testing Menu

[JimmieSmith]

Going in the testing menu from the phone dialer by dialing *#*#4636#*#* and selecting phone information, there are two things that I would like to know the best choices.

1. Should I turn on IMS Registration Required?
2. Should I turn on LTE RAM Dump?

Any help anyone could provide is greatly appreciated.

Thanks!

If it is not selected by default in the testing menu, I believe I would leave them as is.
I haven't looked at the test menu on the XPE yet, but I have fooled around some with it on Samsung S3's and S4's.
What are you looking to do?

So I turned on SMS over IMS and it resulted in no noticed change in SMS or MMS delivery.

Then I turned on IMS Registration Required, restarted my phone, now on day two and I have been connecting to T-Mobile band 12 when band 4 gets too weak.

I have been trying to connect to band 12 in rural areas or other weak spots to no success until I changed that setting. I will test more in areas of where I was roaming but the map shows LTE coverage and update.

Now, just to determine if turning on RAM Dump is OK to do. I turned it on then off again and didn't notice a change.
