bad signal related to the radio version?

So I decided to Root, S-Off and flash Coredroid v4.7 on my Inspire, but I leave it with the stock radio (12.39.60.19P_26.06.04.06_M), but the signal seems pretty weak even on places where my Nexus one was at full strength my Inspire seems to only be able to grab 2 bars at much, and the WiFI connection seems week too, on my N1 I used to be able to get full signal from more than 20 meters, but my Inspire seems to lose it after 15 meters.
I read some posts and other blogs/forums and some attribute those issues to the radio version, so I hope someone can give me an opinion and tell me if I should Update the radio and to which version if so.
Thanks in advance.

Try this
For phone signal, try *#*#4636#*#* in the dialer. This will bring up a screen that has 5 options, I went to phone and scroll to the bottom. Under the preferred network I changed it to GSM only as its an AT&T phone anyway, I was getting 1 or 2 bars at home and was missing calls left and right. after setting this, back out and shut the phone down then restart. I have all 4 bars now. It would also eat the battery, mine was on WCDMA preferred and I think it was searching for that signal constantly. There is a screen for wifi also but there is nothing adjustable there.

Odd that it would have WCDMA preferred as default. I just adjusted this as well and it improved the signal in my office. Good catch.

Gsm only does not work for me, my lame carrier runs on gsm but their mobile internet runs on their 3g so I need to connect to both. Setting it to wcdma/gsm auto seems to have improved the signal

Hey all, I'm on AT&T running radio 26.06.04.06_M. Any specific recommendations? GSM/CDMA Auto (PRL) seems to give me the best service based on bars, but that doesn't necessarily mean much (I'm on an HSDPA connection with 3/4 fluctuating right now).
Also, I think I might not have HSUPA enabled with this radio, I'm only getting .56Mbps upload and around a 2.79 download (Whereas on standard 3G with my old iPhone I typically pulled around a 1.2). HSDPA is without a doubt enabled and it shows that I'm connected on that network, but is there a better radio I should try out?

Thats what i thought and when I tried that it only gave me an "E" signal so I went back to how it was WCDMA

Nice just changed mine and full signal now. Thanks guys.

[Q] Any way to get WCDMA/LTE only mode?

Does anyone know if it is possible to get a "WCDMA/LTE Only" mode on the Nexus 5?
I basically want to stop the phone dropping to 2G. Recently LTE has been made available here and before that I used "WCDMA only" and it worked fine but that is no longer a viable option since I want to use LTE.
Thanks in advance

Can't you just switch off 2g dialing 3646?

So you don't want to be able to make phone calls?

I do, but I can use 3G to do this. I mean I don't want it to drop to EDGE.
The reason is, in Ireland the network provider Three does not have a 2G network and roams to Vodafone when it 3G isn't available. It then will not automatically change back to 3G. You need to manually select the Three network again.

you have no option then. you have either lte only, which gets you data and no phone calls, or you have lte/gsm. on gsm/lte, itll switch to whatever is your best signal.

Wouldn't it be easier to choose the operator manually?

That's what I thought. I was just hoping there was some custom software of some sort that would solve my problem.

It still jumps to vodafone when there is poor signal, even when manually selected. If there was a way of forcing it to stay with one operator or disable roaming completely, then that would do but there doesn't seem to be an option.

Are you sure there's no "national roaming" setting?. I really thought there was.

Not on the Nexus 5, as far as I'm aware. I think it just disables data anyway. I need to be able to disable roaming completely or restrict to WCDMA and LTE.

When looking in SlimKat (admittedly not stock), it is @fergietime suggests, national data roaming and would still allow the phone to roam to another operator when there was no signal on the existing operator - just with no data. However, I am not seeing a problem with that. It only roams nationally when there is 0 signal for voice on your operator?

Yes, but it happens me quite often due to certain places that I pass through. My operator does not have a 2G network at all so roams once it drops below 3G. The main problem is, I need to manually search for networks and select my network to get it back to 3G/4G. It's a network issue that Three Ireland refuse to acknowledge. It has been happening for 4 years at least. I am just looking for a workaround.

I see.
I am also on Three (UK though) so also have no 2G coverage. and yes, when it fails over to 2G (Orange in UK) it is a pain to get it back.

It's a very frustrating issue. It actually NEVER jumps back to Three and it changes to Vodafone nearly every time I go inside a Tesco or somewhere like that. I then have to search and wait for it to find networks so I can select Three. The only time it seems to work correctly is when using a device bought from Three or a Three rom, which obviously for the Nexus 5 doesn't exist. And even then people complain about it so it's a bit hit and miss.

Does anyone know if it is possible to add a "WCDMA/LTE Only" mode into a rom?

[Q] Nexus 5 only connects to LTE on T-Mobile

I did some searching around and found a couple of pages with ideas but they have not worked so far. Here's the deal, my son's said his Nexus 5 was getting pretty bad reception so I took a look at it. After some toggling of the network settings I discovered that it will only connect to LTE, not to HSPA(+) or Edge. Where we are, we have somewhat weak LTE (2 of the three towers have been "modernized" with LTE and band 2 HSPA+, one has not and it's slightly closer to us). We have a Cell-Fi repeater so we get strong HSPA+ signal in our house. His sim works fine in a Nexus 4 with the hybrid radio getting Edge, HSPA+ and LTE. My nano sim with adapter that works fine in the Nexus 4 exhibits the same problems in the Nexus 5. I tried formatting the cache from the stock recovery menu and am now looking to do a factory reset since I never did oem unlock this phone so I can't just flash a radio to test.
My gut tells me it's hardware so I have my son rebuilding his phone environment on the Nexus 4 so that we can do a factory reset to see if that helps and I'll unlock it at that point. If it doesn't fix it, I've already started the conversation with the play store. My question is, anyone else seen anything like this? Anything else I should try out?

if lte is in your area, and not a perfect signal, itll still choose to connect to lte by default. if you lose your lte connection, then itll connect to H or 3G, and so on. if you do not want it to connect to lte, go to the phones main settings, mobile networks, then change the preferred network type from lte to 3G. or you can dial *#*#4636#*#*, chose phone info, then change the network type to wcdma preferred.

Thanks for the reply, I understand all that. I don't know if I asked clearly enough or not but the problem we are seeing here is that this particular phone can only connect to LTE which is weak inside my house. So, when it tries to switch over, it just won't connect. I also tried to make a call which will switch to HSPA+ and that too fails. Going to the info menu and selecting WCDMA preferred nets me a phone that won't connect, selecting GSM results in the same. LTE only or GSM/LTE works only if it picks up an LTE signal. Ditto for selecting 2G, 3G or LTE preferred in the Mobile Networks menu. I've also reset the APN's, confirmed that the settings match my MotoX, etc and still no joy.
Just looking for ideas that someone might have that I can try before blowing away all my son's data on a factory reset or, if that fails, hardware replacement.

ok, i understand now. i didnt know that it wasnt connecting to h or 3G when it should. to me it sounds like a device ready to get an rma. i mean there is a hardware mod that could possibly fix it, but its not worth the trouble. if you can get an rma, get an rma.

Yea, according to the nice person I spoke to at the play store, I should indeed qualify for an RMA and I should find out in the next day or so. I purchased the phone new in box from someone and they were able to find the phone and they are now attributing the phone to me.
I am curious about the hardware mod though. Is this just for Edge/HSPA or is it for signal in general? If it's signal in general then I'm not sure I'd want to try it since this phone used to work just fine.

Phone won't switch back to 3G from 2G

Hi everyone.
I'm having a strange issue with my internet connection. The phone connects to 3G fine, but whenever a go into a zone with no or bad 3G coverage (at work for example) and the phone switches to 2G, it'll sometimes stay in 2G even after going into a good 3G coverage area (at home). It doesn't happen every time, but happens a lot. The only way to make it switch back to 3G is by forcing "WCDMA only" through the *#*#4636#*#* menu. I could just leave it there, but then I'd have no connection at all when I'm at work, so I switch it back to "GSM auto (PRL)".
Usually, when the phone parks in EDGE, the network settings don't change, it stays in "GSM auto (PRL)" but it just won't switch to H. Today, though, it switched to "GSM only" by itself, which it had never done before.
I had this same issue with my previous phone (Huawei ascend P6), so I thought that it was probably a problem with the SIM card, so I asked for a new one but nothing changed.
I've seen a few posts regarding similar issues but most of them are very old and none of them have been very helpful. I hope someone can give me a hand here.
I have a Nexus 5 running Android 5.0 - No root
Thanks.

My phone sometimes gets stuck in 3g instead of handing off to LTE. I just toggle airplane mode on and off and it immediately goes to LTE. I know it's not a fix, but it is a pretty quick way to get your data back.
Data connectivity issues are by far the most irritating, considering how much it costs to have a device like this...

Thanks for the suggestion, but unfortunately that doesn't work for me. The only way is through the #*#*4363*#*# menu.

That sucks man.
I'm not sure there is a fix for this. Other than Google fixing it in the baseband. You would think that if the problem were in the source code that this would have been resolved by some of the devs here on XDA. I have had these problems for a few years, and on other devices as well.

I guess I'll have to live with it. Thanks anyway, man.

phone losing connection? going to sleep?

I've read a few others with this issue. Randomly the phone will seemingly loose connection will not recieve calls or texts until you pick it up and use it. And 50 texts start coming thru. Etc... I'm on T Mobil, have great signal. I've toggled 3g preferred, 4g preferred, and have developer options enabled, keep connection at all times. Still does it. Any thoughts???? Or help would be appreciated

Thanks but this isn't my issue. Phone seems to struggle switching bands. From 4g to 3g and gets hung.
This phone connects to T-mobile 4g fine for data. But for sms and calls it goes to 3g, as it doesn't have VoLTE...seems like it doesn't switch all the time or get hung up. I've tried turning off 4g. This seems to help. But the phone has a definite issue. Not sure if it's considered normal since it's not utilizing 4g for voice and one of the little things you have to live with

There's definitely an issue, and it's not just with the Tmobile sim. Sometimes my china unicom Sim says no service too. But they won't say no service at the same time. It's one or the other. I've tried to switch the sims to other slots but same thing. I know its an issue with the phone because when my phone says no service, i look at my wifes phone and she has full bars on her phone. (pixel 2 xL in china with Tmobile USA Sim roaming on china mobile)
Must be a software issue

I have an similar issue... Just it's only for my 3G/4G after 10min of utilization i lost connection (call & sms work fine) and my phone say all is ok (I have the 4G icon...) I forced to disable / enable the Data 1 or 2 times for 3G/4G come back... I have Global Rom & SFR french network

Same problem 10 min data off for like 45 seconds n comes back by itself

Hmm similar problem. Having trouble getting calls on Tmobile. Lots of people calling and going straight to voicemail.
