as the title suggests is there anyway this is possible? i have the network mode set to lte/wcdma/gsm auto connect but the issue is that i live in an area with low lte coverage and the phone will not switch to gsm mode even when the lte signal is close to none which causes sms not to be delivered and i don't recieve phone calls and it causes a huge battery drain on idle when i go to sleep and wake up with the phone even off sometimes..the issue is gone when i switch to gsm only but it is a pain to constantly go back and forth between switching networks any suggestions?

Is it normal behavior for the Amaze to take a two and a half minutes or so to find a signal for the mobile network? Also the "network mode" always defaults to "gsm/wcdma auto" even if I select GSM only.
In this time if I pull down the notification bar and go to quick settings, I am unable to check the "mobile network" the checkbox is kinda dimmed out/greyed out.
If I manually go in and search for network, it will generally connect faster.
Just wondering if this is normal or not... so I know if its a hardware issue and I should return the phone for another.
appreciate any comments.
The GSM/WCDMA selection is "normal" behavior for the amaze. (and it's extremely annoying). It seems to be a setting with the ROM and since I rooted and went with Beast, I no longer have the problem.
As for the searching for mobile network, that's sometimes normal. It generally happens when your in an area where T-Mobile is not the dominant signal and prevents you from latching on to a roaming tower rather than T-Mobile.
My SG2 is set up in network mode with GSM/WCDMA(Auto mode).
When I’m home the signal strenght, WCDMA, is -101 dBm 7asu and the voice quality is very bad, almost unusable.
When I manually switch to GSM the signal pops up to -73 and 15 asu and I can talk with a sound quality as it should be.
To me it seems that the phone doesn’t switch to GSM, or too late, when the WCDMA signal is bad.
I have tried quite a few different modems for the SG2 but I can’t see any difference between the versions. Maybe it’s the network provider that manage when to switch?
If would be great if someone could give me some info. on how the switching between WCDMA and GSM works, and the thresholds.
GSM auto (PRL) will favour GSM over 3G.
I am not sure if it will work with your network, but you can only try...........
There are a few apps around that will do it, or you can just use the following:
1. Phone dialer *#*#4636#*#*
2. Phone info
3. Set preferred network type to : GSM auto (PRL)
Edit: I am not sure if it will revert after a reboot.
This post was rather useful info, although different phone and network, principle is the same:

Click to expand...
Click to collapse
1. Disable Mobile data, then wait for 3-5 minutes
2. Enter Service mode, then change network to WCDMA only, repeat it like 2 times.
Done.
Correctly good luck...

my problem is described here -Can others be so kind as to verify if they are also having an issue with receiving voice calls or SMS while their phones are using the 2G network for data access. (3G and wifi either unavailable or turned off.)
We have this issue with Orange and I have tested it on one Sunrise iphone4 and we had the same issue. Which is not surprising since Orange and Sunrise are operated by the same staff. It does work correctly over Swisscom.
I raised this case with Orange over one month ago and they still have given me no concrete feedback as to why their network behaves like this.
(FYI this is a network issue and not related to any phone configuration).
Feel free to harass Orange about this. It might get them to pull their fingers out a bit. When I raised the case it took me about 10 calls to their support plus 2 visits to Orange shops to finally get a technician who was capable of understanding this simple but critical issue.
EXACT STEPS LEADING TO PROBLEM:
1. Force phone to use GSM (2G) mode only or be in an area with no 3G coverage, or if your phone chooses to use the 2G network
2. Disable switching to wifi:
3. Connect to 2G packet data, download email or download webpages: Status Bar-> spinning wheel
4. While packet data is connecting, using another phone place a call to your phone
5. After packet data has connected, using another phone place a call to your Phone
EXPECTED OUTCOME:
You expect the packet data connection to either DROP or be SUSPENDED (depending
on network capabilities) and for the phone to ring indicating an incoming call or SMS.
ACTUAL OUTCOME:
The packet data connection persists and remains active; the phone does not ring
and the call is handled by the network as if the phone was unreachable (for most
users this means forwarding to voicemail).
REPRODUCIBILITY:
always; no exceptions.
This has been tested extensively on the Orange network by me and many other users.
Tested devices which all show the same issue, iPhone4, iPhone3GS, Iphone 3G, several Android models.
Hi!
Just a quick question,
I forced LTE in the service menu but found out that calls and SMS don't get through because they use 3G. The phone switches from 4G to 3g very sensitively, even though a "weak" 4G connection seems to be much faster than a strong 3G.
Is there a way to configure when the phone switches to 3G or is it possible to force 4G but still somehow get calls and messages?
I'm rooted and will try anything
Thanks
I have poor reception where I live and I've heard switching to 2g helps with that. But I don't want to be switching to 4g when I go out and changing to 2g when I get home.
