Bad signal with 3G/H+ - One (M7) Q&A, Help & Troubleshooting

Hey guys.
I figured out something weird what piss me off a bit.
When im using E/2G mobile data i have full signal. But when i use H+/3G i have 1 or even 0 signal and the result is a bad internet connection.
You know what the cause could be? No matter what rom i use, i have it on every rom. (Sense, GPE, slimbean). I attach a Screenshot where you can see my baseband Version.
Thanks

Bad 3g coverage in your region? Did you compared with others devices?

2g / Edge is the original voice network with data added.
3G / HSDPA is a completely different network and offers only a data connection.
So its possible your 2G and 3G connections are so different due to locations of the tower.
Its also possible the antenna in your device might have a problem with the 3G so unless you get another device to test with its an either or.
But at least now you know that 2g / 3g / LTE are in fact different networks.

have you tried to go back to your carrier's stock rom?
If I tried but not working still works only on 3G, I flashed with SmartFlash and nothing as usual

if you want to connect to 2g to save battery you should just try one of the cm7 based roms that have great battery life.
If you want to be in 2g just because you want to or because you don't have 3G coverage in your area, then you should probably contact your carrier (with your stock rom) and complain about it, if possible try a few different phones to see which ones connect to the 2g networks.

Force 3G?

Hi,
I'm with 3 in Ireland and where the 3G coverage is limited, 3 have an agreement with Vodafone to use their 2G network.
This is fine, however frequently I'm connected to a 2G mast when there is a 3G mast available.
Unlike other phones there is no option to select 3G networks only in the options (I have to manually search for networks and then select the 3G one - this takes a minute or 2 each time).
Anyone got any ideas?
Is there an app that will force 3G connection only?
The phone is unlocked and rooted and currently running Orange GB JB...
I found an option in the secret menu ( *#*#4636#*#*) to set WCDMA only - I'll give this a go for a while and see how I get on...

About to do the same, it drives me crazy to spectate that freaking R letter (same Irish 3). But have a question - what happens if no 3G network around (coasts, for instance)? Will it switch to Vodafone network or just stay without any?

Navigate to system/etc/motorola/com.android.phone and edit your default.xml like the attached Screenshot > reboot > profit
Backup your default one, just in case!

I hope this is not too off-topic, but does this xml file has something to with me not being able to chose GSM Auto PRL on my device (unlocked and rooted) using *#*#4636#*#*? (always reverts back to WCDMA only) or does it only change the menu?
Switch back to automatic before you trying to change to GSM

i know it's somewhat offtopic but does someone know if it's possible (i.e. by some lines in build.prop) to enable the national data roaming mode in jb (omars rom)?

[Q] How to get "real" 3G speed?

Hi guys!
I just got my contract with mobile internet in it.
Each month, I get 1GB of data and it's awesome!
But I have some questions/problems with it.
When I connect to the 3G network, I sometimes have an E-connection.
It's pretty slow, but I found out this is some kind of 2G netwerk (called Edge).
Mostly I get an H-connection (HSPA(+)) I think and that speed is fine.
But sometimes it changes from a fraction of a second to a 3G-connection.
I think that is what I really need, but how can I "force" it to always go to 3G?
My carrier supports Dual carrier 3G, so that "should" double my 3G speed.
It would be awesome if you could help/inform me!

H (HSDPA or HSPA) is faster than 3G is faster than 2G.
I also get switching from 3G to H a lot at home were signal is not good.

Owww, like that!
But how can I check if my HTC One is using the Dual Carrier 3G-speed "technology"?

[Q] Force 2G mode when on home wifi

Hi,
I have patchy 3g but a good 2g signal when at home. The problem I have is my Z1 keeps flipping between the bad 3g and the good 2g.
When I'm at home I would like it to be forced to use the good 2g signal only so I would like it if the phone worked from 2g only when it recognises my home wifi.
My original thought was tasker but when I tried it, the radio section is not available, saying not compatible with this device.
Anyone know what else I could use ?
Thanks,
malty

When connected to wifi, doesn't the phone just turn off all mobile data? Mine doesn't show 2g or 3g or any indication of any mobile data being active when on wifi. Unless I'm missing something?

It's not data that's the problem. for calls and texts it is still connected to either a 2g or 3g mast. I need it to be looking for and connecting to a 2g mast only, since the 3g mast where I live is poor signal and is intermittent but since the phone would prefer a 3g over a 2g signal, it tries to connect to it anyway.
As stated I would like it to be in GSM (2G) only mode when I'm at home and automatically switch to 3g(preferred) and 2g when away from home.
Hi,
I know this isn't exactly what you're looking for but you could try installing this ROM.
http://forum.xda-developers.com/showthread.php?t=2463675
It's listed to have a force 2g option and you might be able to find a way to automatically trigger it.
I also found a Radio Switcher app in the Play Store, but again, not perfect.
Hope this helps.
Andrew
As far as I know, you can't have automated 3g to 2g switching even with a rooted device because android prohibits it.

can you not do this with tasker?

tasker will do it but the radio section in tasker is greyed out with the explanation 'not available for this device'
From what I've read changing network settings is protected by Android, and thus not possible if running a rooted stock-rom.
If someone comes up with an idea how to rescan/update the settings without a reboot that works (http://forum.xda-developers.com/showthread.php?t=2230207), please tell as I also have horribly bad coverage of >3G at home.

[Q] 4G Issue

Hi
I have a Z1 brazilian 6943 and my carrier is Claro. As you probably know 4G in Brazil is not great, even 3G is not 100% reliable so I have question that so far no one was able to respond to me.
When I leave the LTE(preference) WCDMA/GSM active under networks and I have 4G signal everything is ok, but the problem is that 99% of the time is not ok, there is no data available. So I expect the phone understand that LTE is not available and uses the 3G network but this doen not happen, I have zero data availability and I have to change from LTE (preference) WCDMA/GSM to WCDMA(preference)/GSM to have data...
Any one of you has the same situation? if so is there any way our phone understands that there is no 4G and uses 3G instead I have to do it manually?
Regards
Renato
No one has this issue? Any reply will help a lot

That's exactly the problem i have as well in France, the Z1 handle very bad the 4G, if you can't have a decent 4G connection just don't select it in network preference because u'll have signal problem. It's fine only when i'l folly cover by 4G, if it's not the case, just disable it in the notification and all will be Ok.
