[Q] Diagnostics settings

The T-Mobile G2 has *#*#4636#*#* to enter the diagnostics function.
Would there be anyone out there that could give me the best (performance) settting options that I should select with my G2 when in the diagnostic mode? Thanks in advance!

I mostly use WCDMA only. You also can downlaod AnyCut from the market and load the shortcut PHONE INFO and it will do the same thing as dialing those numbers

Also too, why do I use WCDMA only is for it only looks for HSPA+. That way if I'm say in walmart it does not go back and forth on HSPA+ and Edge all the time. If its not 100% HSPA+ than my cell won't connect and waste that little bit of battery roaming

If you're in a city with good HSPA or 3G coverage, use WCDMA preferred. If you're in a city with spotty 3G/HSPA coverage, use GSM auto (PRL). The first will connect to 3G/HSPA if at all possible. The second option needs to reach a higher signal threshold before it switches to 3G/HSPA. I've tested both.

I know this is a newb question but what does it mean when you see all of those numbers and symbols? Is it a number to call or text? I want to know because I say it under the OTA post in order to "Check In" but I have no idea what it means or how to use it.

Its basiclly a code to get into phone information on your cell

You enter it just like a phone call, then it will present the Phone Info menus to you. To checkin, it's the same sort of thing, just dial *#*#2432546#*#*
Hope that helps.

Is there a network mode to toggle 2G/4G on T-Mobile?

Wondering if there is a way in the network settings to force 2G ONLY or 4G?
WDCMA Preferred
GSM Only
Something like that?

Only way is dialing *#*#4636#*#*
And selecting it there.

This app is much faster than dialing:

I use it all the time to quickly change from HSPA to EDGE.
You're welcome.

2G disable

ok 2g Networks are terrible just too slow and i hate using it
Is there a way that i can completely disable 2g netwroks and use 3g only on my GSM galaxy nexus
PS:I'd rather have no internet than using 2g network

[Q] Is there any way to force HSPA/turn off LTE?

I get horrible LTE reception at work, and I know that my battery is paying a heavy price. HSPA on the other hand is great (4-5 bars usually).
On my Galaxy S4 I'd open *#*#4636#*#* and open up the device info and change the Network Type. But, the Nexus 7 doesn't have a dialer. Is there any other way to force HSPA on the nexus 7?

You can install ICS Dialer for example, enter your service code and get into the service menu. I tried, it works.

Yup, that worked perfectly. Thank you!

You can actually do this without having to install anything, though the app might make switching to and from a bit easier:
1. Go to Settings
2. Connections (tab)
3. More Networks
4. Mobile Networks
5. Network Mode
6. Change the network mode between LTE/WCDMA/GSM (for LTE) and WCDMA/GSM (for non-LTE)

How to switch 3G Only

How I can switch my Fire Phone to 3G Only Band? Some App or somthing? Who help? :what:

Go to the dialer, enter *#*#4636#*#* and tap "Phone Information". On the next screen, you can select 'WCDMA preferred' from the drop-down menu. However, I'm not sure if the phone will automatically reset itself back after a restart or whatnot.

Yes. I discovery that. Its simple and easy. Now for me, a very good phone.

Is there anyway to turn off 3G ? for use 2G GSM only mode , I want to use EDGE option since my area has the weak 3G signal.

You follow the same steps I gave in my previous post. Instead of selecting WCDMA preferred, you select GSM only in the drop-down menu.

Thank you it works great without reset the phone.

And easier and lazier way is to install the app "Phone testing", it is the shortcut to the same menu. On Motorola phone the app is required because that dialer combination doesn't work.
