[Q]build.prop radio related settings

Everything started when I've made some tests and I've noticed some strange things:
- on every KK ROM I've tested, mobile data drops completely after some talk time. It is happening only during calls (long calls usually). It is regardless of the radio used, I have tested it with 1.13, 1.15 and 1.20...the same with all. It is also happening regardless of the call type: on BT (car-kit or headset), speaker, headset, handset. EDIT: Now I made some tests and seems like I don't have this issue anymore but instead I have the issue below. I don't know why and when this started to happen
- as soon as I make a call, the mobile data icon switches from H/H+ to 3G. As soon as the call ends, it switches back to H/H+. I've run some speed tests and it's not only the icon, it's the speed too. I get about 0.09 Mbps during a call with the 3G icon and up to 8 Mbps when not in a call with the H/H+ icon.
Now there are some build.prop entries I don't understand and I couldn't find any explanation on them. There are many threads in which some of them are recommended, some say they work, some say they don't, I am really puzzled. Below there are a few about I couldn't find any details:
- ro.ril.radio.svn = usually value here is 19 but I heard about 01, 02, 03 or 04 as well. Nobody seem to know why it's one or another and more important what does this does.
- ro.ril.hsxpa = usualy 2 but I saw many people recommending 3 or 4 without any arguments on that. What does 3 or 4 do here? Don't say it's enabling HSDPA or HSUPA because the lower values already do that: 0 = UMTS, 1 = HSDPA, 2= HSDPA/HSUPA. So why 3 or 4?
- ro.telephony.ril.v3 = now this is a nice one. Mostly I've seen this set as skipradiooff but I found more: icccardstatus, skipbrokendataca ll ,datacall, signalstrength, facilitylock. What's this all about? What any of these options do?
Now why I ask such stupid questions you'll say. If they work who cares...ok, but DO they work? Has anyone tested if they change something? If yes maybe those persons could bring some light here because nobody seems to know. And I mean if one of the above do change something, the ones that tested and recommend these settings should at least tell us what happens if one or another option is included.
Has anyone commented out for example the ro.ril.radio.svn and see what's happening? Or put 01 or 04 instead of 19 and see if any change? Cause I couldn't find any difference with this option set or not. Why is then recommended? Maybe it's particular to some carriers (I saw alot of settings related to US T-Mobile). If it's true, maybe it's good to know that only for that carrier it does something and on any European carrier it has no effect (or it has, I don't know)
Please anyone who knows some info or made some tests post here. Maybe we could shred some light into this cause after searching and searching I couldn't find anything clear. Everybody is mentioning those with one or another setting but nobody explain.
EDIT: I've start testing
ro.telephony.ril.v3 =icccardstatus - this seem to show a "no SIM" or "insert SIM" icon instead of the cell signal icon. Even so, calls CAN be made, I've tested a few. Probably this disables the ability to read SIM card status so that's why it shows that no SIM is present
ro.telephony.ril.v3 =datacall - this disables completely the mobile data. Icon for mobile data is gone and there's no mobile data access. Browser and any apps are reporting "no connection"
ro.ril.hsxpa = I hope it is not my imagination, maybe others can test as well but here's what I found. If 4 is there, most of the times I get H indicator and speed. If 2 is there, I mostly get H+ indicator and speed. So strange but at least in my case 2 seems to be better than 4 (which anyway I don't know what means). EDIT: Ok, after further testing and searching it seems that value of 3 means HSDPA "uncapped" and 4 means HSUPA "uncapped". So it could be that 4 is better than 2 or 3 but this has to be tested for each particular carrier to see if it's really improving something or not
ro.telephony.ril.v3 =skypbrokendataca ll was the fix (100% of the time) for a data acquisition issue on the HTC Sensation for TMOUS customers. Ironically, it causes a lot of 3g connection problems for non-TMOUS customers though. The problem it fixed was a blinking H or E with corresponding lack of data. Many times, sending a MMS would fix the issue as well, but not always. (thank you @nicknc for clarifications)

Thank you, I'll add this info in OP. Also that should have no impact on Ville in this case
I've also read alot about that H/H+ switch to 3G during calls. Unfortunately I cannot test myself because I don't have 2 phones but I'll keep searching. As I read, it seems there's a similar issue with those having LTE networks (or 4G how it's called). It is known that the LTE network is not capable of having voice but only data. The only way of having voice in a LTE network is via voice-over-IP that is not implemented. That it is called VoLTE (Voice Over IP over LTE) and the project for introducing it has already started but it'll take some time till it'll be finalized. Therefore, if someone is on LTE network will notice that during voice calls the mobile data switches/drops to 3G and resumes on LTE as soon as the call ends (or not...for some carriers it has to be manually switched back). This is implemented by the carrier and it's called CSFB (Circuit Switched Fall Back). The internet is full with complaints and questions related to this data drop, especially in US but it is also in Europe or other zones in which LTE was implemented. Lot of people asks how can they prevent this to happen...short answer is they can't, only way is to change the data plan back to 3G from LTE. More details can be found by searching on Google and also I found this technical article HERE (for those interested in such details)
Now what I believe (but I can't prove or test), is that for the same reason I have that switch from H/H+ to 3G. Vodafone RO has LTE implemented and it could be that when someone makes a voice call, mobile data is automatically dropped to 3G even if it is not on an LTE data plan. When I tested with someone else on the same carrier, he didn't have that dropped data but also he was not living in an area with LTE coverage so it could be that this is happening only where LTE is implemented (that's why I need more time to test and find persons who can help me).

Okay-- a few updates for TMOUS
I tried ro.ril.hsxpa set to 2 for a few days. No appreciable difference, other than an appearance of a tendency to hold onto 2G longer than the phone should in a high-coverage 4G environment.
I also tried hsdpa set to 24 and hsupa set to 6, as everyone likes to whine about how our phone doesn't support values of "28" and "7".
This is where it gets interesting. Regardless of the setting of ro.ril.hsxpa to "2" or "4", I do not get H+ indicator with hsdpa set to 24 and hsupa set to 6. When I flip it back to 28 and 7, I get the H+ indication. There is no appreciable difference in speed, but then again, I am currently getting a speed lower than what I get when at home (10 mbps vs. 14 mbps). So, it could be 10 mbps is the max available on the tower to which I am currently connected.
The upload seems to be lower than normal (2mbps), so it is likely that conditions are not ideal.
When I return home in a few days, it will be interesting to see if there is a difference there between 28 and 24.
It does appear some of these settings might have infiltrated from other HSDPA+42 or even LTE phones, and wouldn't necessarily apply to ours.

The 24 for hsdpa and 6 for hsupa is from the table I found and tells the maximum speed at which device can download or upload. It is useless theoretically to set higher values since the device is not hardware capable of achieving them

Yeah, I understand that, but the strange thing is the lack of H+ indication for me on 24/6.

Should be another reason...I have H+ and I have the same 24 an 6 values. I am currently using the following
ro.ril.hsdpa.category=24
ro.ril.hsupa.category=6
ro.ril.hsxpa=4
ro.ril.radio.svn=19 (still don't know what it does but ...)
ro.ril.fast.dormancy.rule=0 (my network doesn't support fast dormancy)

I've used those values for many months, along with
ro.ril.disable.power.collapse=0
ro.telephony.ril.v3=skipradiooff
and I always get the H+, though my data rates have really gone to hell in the last few months...5Mb is good for me these days.

Ok, and what does that "skipradiooff" do? Because nobody seems to know. All are putting that setting in build.prop or recommend it but nobody could tell why. To be honest I didn't notice any difference with or without it
Could be something specific to T-Mobile and in this case that's why I don't see a difference

[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?

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?

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.

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] Phone disconnects from mobile network when of WiFi and LTE

I have an issue with my One.
When on WiFi, my phone sometimes disconnects from the normal mobile network - and I don't mean data transfer, I mean that people are unable to call me.
What's irritating, my signal strength is reported as usual, stating that it's connected and with great signal strength. I'm doing it in the center of the city, so the carrier signal is not an issue.
After I disconnect from WiFi, normal connection gets back to normal (sometimes I see a little blink of no signal strength).
This is a deal breaker for me! I mean - my phone does not receive phone calls and I am not even aware of that, because the signal strength indicator shows max.
This has happened three times already (or more, and I am not aware), since Friday.
I have rooted the phone exactly according to http://forum.xda-developers.com/showthread.php?t=2788632 - no other modifications.
Could use some help... Search yielded no results, I don't even know the tools I should be using to troubleshoot that (logcat?).
[EDIT]: Can't really tell if WiFi is the actual issue, but I suppose so. It only happened on WiFi, and with synchronization enabled it might realize the loss of connection and notify about it.

I have filed a bug here: https://jira.cyanogenmod.org/browse/BACON-466
After some research I've found some additional info, that it's a matter of having both WiFi and LTE turned on (thus I have changed the topic of this thread).
There was a workaround for Nexus 5 described here: http://forum.xda-developers.com/google-nexus-5/general/tutorial-missed-calls-workaround-t2801654
And a discussion on Google forums, link in the comments of my bug.
I believe that it would be nice if someone could verify it. People reported that it happened on US T-MOBILE, but not on AT&T. I believe that Intelli3g solution posted in Nexus thread would work here as well.

Using the EU Version in the US

I'm considering buying the European version of the xz premium for use in the US, since it comes with the fingerprint reader already enabled, and is about $100 USD cheaper. However, I've seen some people raise concern over the cell reception when running the European firmware. I'm wondering if anybody knows if this could be due to the European firmware not matching the physical bands included on the U.S. device (of if that's even a thing), and also if that could be somewhat solved by just getting it straight from Europe. Is there anybody that has the European version that could speak to the cell reception quality in the United States?

If you use the European device in the US, you also have to change the settings for the used bands.
There is an option to change used frequencies in *#*#4636#*#*. Guess that would make a difference since the hardware is always the same.

This is exactly what I was looking for. Thanks. I didn't know that they all had the same physical bands

You don't need to change anything.
When you pop in US sim, all bands are available and appropriate LTE CA combinations are loaded.
3G calling will work, but you will miss out on VoLTE with euro region firmware.

Bought my XZP from Clove UK.. Using it in NYC.. No probs with reception.. No need to change anything, all I did was pop in the sim card, working great ?

I recommend to change the radio configuration to "United States" just in case.

I just popped in my AT&T sim and no problems. I did set the bands to the United States...makes no difference as everything works the same.

UK model G8141 here in US. I just put my AT&T sim and got LTE and great connection right away. No worries.

I ordered mine from Clove as well, and while it does seem to work just fine with my AT&T SIM, I always have only 0-2 bars of signal and the phone always shows 4G/4G+ instead of LTE. Anyone else have this issue? I've been trying to do some digging to see if perhaps there is some setting that I need to adjust such as the APN used or something to get better signal strength. Thoughts?

First of all, 4G in the UK is the same as LTE in the United States, so no issue there.
Do not look at the bars as this can be manipulated by the programmers. To see how strong your signal really is you need to go to settings > about phone > status > SIM status. The lower the number the better. I am fairly certain that if you DO NOT use 4G you will get a stronger signal which may be perfectly fine unless you need a real fast signal. By not using 4G you will be using 3G. Hope this helps! :good:

Oh good. I was wondering about whether or not the UK actually called it LTE like we do here.
My average signal strength seems to be -119dbm 99asu pretty much regardless of where I am in my city. It just seems weird since my Huawei Mate 9 got consistently better signal than this in the same market, with the same SIM, supporting the same frequencies. Just makes me wonder if there's something I'm missing or if I should try getting a new SIM from AT&T.

I doubt that a new SIM will help anything. Those numbers are quite high. Too high in my opinion. If you do not stream videos or something that needs very fast LTE signals, then I would choose to not use 4G. You should get a much lower number (better signal) and everything will still work just fine.

You mean having it download mms and Internet settings, then reboot? I've done that a couple times but I never rebooted after doing it. I did notice that in my APN settings, there are two for AT&T and I can't find an answer as to which one to use. One is called "phone" and the other is "nxtgenphone".
My download speeds aren't terrible but they aren't super amazing either. Last I checked it was 35mbps down and about 5mbps up. I'll try reprovisioning and restarting and see what happens. It just sucks not ever having more than 2 bars no matter where I am.
Edit: just tried downloading mms and Internet settings again but it didn't help. Maybe I should reset my network settings to default and try again just in case?

Mine is set to nxtgenphone. I really wouldn't focus on the bars. My z3 was also from the UK and did the same thing. You can check under the diagnostics settings screen to see what your data connection is or try doing the magic combo number to see what bands you're set to.
Is there anyone with a phone on the same carrier that would pull up their signal strength info so you can compare the actual numbers?

Maybe someone can give me some but others have told me that averaging -119dbm 95asu is a pretty weak signal.
Others have said I shouldn't need to change any settings in the hidden phone menu, but I set it to United States just to be safe. I didn't mess with any network settings in there aside from that.
Edit: checked radio band setting and set it to United States. Network preferred type is set to LTE/UMTS auto (PRL). Not sure if I need to change any of these settings or not.

Whenever I test it in the hidden menu the IPv6 test always fails. Even AT&T's official documentation says not to use the IPv6 but I'm not sure what to believe since the downloaded settings have it enabled.

S10e 9700 LTE connection issue

Hi,
I recently recieved my G9700 and until now I'm quite happy - apart of some connection issues.
At home I get 2 or 3 bars 4G after log in. Then after some time this changes to H/H+ or even down to E, but never changes up again.
So every loss of connection speed is permanent until next log in.
Am I the only one having this?
Are there possible solutions?
Thanks,
Derk

It could be either a hardware fault or network issue. You need to run some diagnostics. Change sim card to another network carrier and see if issues persist. Also the first thing to check is your APN settings before anything else.
