[SOLVED] 3G data connection hiccups.

Hi there,
I'm using Revolution HD 3.6.1 with its radio and relative RIL (which becomes with the rom by default). Obviously I have S-OFFed and rooted.
I'm experiencing some hiccups in 3G data connections. I don't know if it's due to the carrier (Wind Italia) or something in the phone (maybe the radio doesn't support it at all?). I'm in Europe, precisely in Italy.
Maybe should use an european version of radio? Or what?
In detail:
I activate data connection. The phone shows 3G before, and quickly goes in H (HDSPA). Then I use many apps that needs internet connection. Within a short time it goes again in 3G and i have absolutely NO data connections. After a delay of 5-10 sec it goes again in HDSPA and everything works. When it goes again in 3G i have no data, then again H and data working.
What's the problem?
EDIT: Problem solved! See in this post.
P.s.: Sorry for my bad english

I was going to ask about something similar to this, so rather than start a thread I will post it here. I too am running the 3.6.1 with its radio, S-OFF, & rooted.
What I am seeing on boot up is the standard progressive upgrades of data networks (just bars, then 2G, then 3G, finally H). The H only stays for a few seconds then drops to 3G and basically stays like that. However, as soon as I open an internet requiring application, it jumps to show H and typically stays that way as long as a data connection is active. My Speed Test results show its 4G speeds (same as stock ROM and radio) when its showing the H, so obviously its working, I'm just wondering if its intentional that the display only shows 3G? Or maybe its set so the ROM "relaxes" on 3G, but switches to 4G when data is actually being sent/received?
~T.J.

Maybe you used to have a 'background' app updating constantly.
The G, 3G and H usually depends on the signal in your area, the H is usually for high data transfer. If you're not using the internet,downloading anything or updating anything on your phone, then why would you need it on all the time?
3g is usually the norm, so I wouldn't worry!

For my issue, my stock ROM showed me what was available in the areas as I moved around, including showing 4G all the time if I was in a coverage area (which pretty much everywhere around me is). If I moved out of the 4G area for instance, it would drop to show me 3G.
This one just shows 3G all the time, even when I'm in areas I KNOW are 4G; UNTIL I use the data connection, then it switches and shows the H. I know its silly, but I liked actually gauging my providers service by being able to see what kinds of connections were available in various areas.
The fact I have to actually open the browser or run a speed test to see if 4G (H in this case) is available in that area is a little odd to me, why doesn't it just show the connection that's available?
~T.J.

Guys, I found a solution to my problem, googling around. That's awesome.
FYI I'll post here:
1. dial *#*#4636#*#*
2. Go to phone information
3. Toggle ciphering so it's off
4. Turn off radio
5. Turn on radio
6. Toggle ciphering back on
It seems to be working to me. An half hour without hiccups till now.

I have had this problem ever since my hd2 two years ago. I thought it was normal. I'm about to try the fix. If it fixes it you are a life saver.

Aww man same thing. Maybe its supposed to be like this.
Basically for me its for example on the xda app when ill refresh something it will always say processing as soon as the 3g symbol turns to h with both arrows on simutaneously.
Maybe that's how its supposed to be idk.

Glad its not only me!!!! This is a problem. I am in the U.S and i have it also. Ive been trying to figure it out. I have radio 10.15.9035.2_2 and bricked kernel 1.2 i can not figure out if this started happening from when i flashed the lastest radio or when i went with bricked kernel above 0.91 i am still trying to figure it out. *#*# 4636#*#* is only a brief temp fix i know that much. But lets try and put our heads together and get to the bottom of it. Cause its been slowly pissing me off daily. Let me know what you guys hear. And i will keep you updated as well.

Only a brief temp fix? Are you sure?
I'm not having the same problem as before, now. I hope it remains still as it is.

[Q] Desire s stuck on gsm only

Hi there,
Hopefully someone can help because my brain is melting here. Basically I spoke to orange customer services the other day because of totally poor signal. He told me to switch to GSM only, which was fine and I know it can improve your phone signal. The thing is, it's now stuck on there, whenever I try to change it to WCDMA it automatically switches back to GSM?
Any body got any ideas?
Cheers
Ian

I feel your pain. I am also a long-suffering Orange customer. Everything was fine until they climb into bed with T-Mobile. Since then my signal has been so erratic I simply can't trust things like Google Maps to work as navigation. Orange have left me stranded twice bombing out the 3G just as I need it to get home.
Anyway, how exactly did you switch to GSM only? There are a couple of ways of doing it.
Menu> Settings> Wireless & Networks> Mobile Networks> Network Mode = GSM/WCDMA auto.
I suspect it was this one. If this is the method that is changing back to GSM, then try this one;
Open you dialer, and dial *#*#4636#*#*
This will open a hidden testing menu, from this select 'Phone Information'
Scroll to the bottom and see what the 'Set Preferred network type:' is set to.
Mine works well with both GSM auto (PRL) and GSM/CDMA auto (PRL)
See if selecting one of these helps.
Let me know how this goes.

Hiya mate,
Yeah I gave that a try earlier. It seems I have to either have a good phone signal or crap data and vice versa? Pain in the ass. Orange told me that it was because of a faulty telephone mast in my area that has been off since last week. Can't see that being right to be honest, since my signal has been ****e since I first got it in April. Thing is, my sister was having the same problem with poor signal, and she wrote to some higher up person at orange to tell them about it. It ended up with her getting out her 2 year contract, bonus! I'm just going to ring and keep complaining and then write to this person my self, and hopefully I can get out of it my self. Orange is the worst network I have been on!
Cheers for your reply

I might give that a try. I still have a year left, but would love to jump ship and move back to Vodafone. I only went with Orange as my girlfriend was on Orange and magic numbers meant free calls. She then went and screwed things up by moving in! Now I don't need to ring her so much! (facepalm)
My housing estate has a dirty great big cell tower mast at the top of it. My fillings could receive a text message. But even with max strength signal still the 3G is off and on so erratically it's not worth using. They keep telling me that "the cell tower in my area is being worked on" too. That's been their excuse since February.
I have no idea I'm afraid why your phone wont stay on a WCDMA setting however. How are your APN settings? Mine once roamed to T-Mobile without me noticing and would only do 2G.

Yeah my girlfriend is my magic number too, and I live with her as well.. Doesn't make a great deal of sense really does it?
I think you may be on to something with that tmobile thing. Does tmobile allow wcdma?

When I used to do a manual scan for other Networks the following would show up;
Orange
Orange 3G
T-Mobile
T-Mobile 3G
If I try to connect to T-Mobile 3G it wont let me. The one that is just 'T-Mobile' doesn't have anything more than 2G. What happened was my Orange signal dropped out, so it jumped onto the 'T-Mobile' one without me noticing. It then didn't go back to the Orange 3G when I got home.
I just tried it again and got;
Orange
T-Mobile UK
The 2G/3G variants seem to have been dropped and merged into a single provider for each network. I can connect to T-Mobile but still only seem to get 2G.
See which one your connected to. It might be that although we are allowed to use T-Mobile for calls/texts the deal doesn't include 3G.

Yip, that's exactly it mate. I go on tmobile and I can get only 2g, I connect to orange and it let's me have 3G. It jumps between the two networks, and as I have poor orange signal all the time it auto jumps to tmobile! So basically it looks like I'm stuck to 2g if I want to actually speak to anyone! At least now I know what the problem is, but it still doesn't make me feel any better about having to make the choice, and having to constantly check which network I'm on before knowing why I'm getting either poor 2g or poor phone signal. What a headache!
Cheers for your help, much appreciated!

Lately, I've noticed some **** with o2 as well which as I previously recall always had good service, since I been with them for as far as I can remember. I'll have full 2G signal, and randomly the data will shut off. Sometimes for a few minutes, sometimes for hours. But the phone signal remains on full... it's weird. And 3G coverage seems to be getting worse instead of better. None of this makes sense either since in March o2 apparently rolled out 900 Mhz 3G across most major UK cities, meaning 3G service on a 2G band, meaning much better 3G service in areas where only 2G service was previously good. I ain't seen **** all of an improvement, like I said it seems to be going the opposite way.
UK used to be ahead of the game when it came to cell networks, it seems most other countries have not only caught up, but jumped miles ahead. 4G is pretty standard in the US now, and they were so far behind in cell networks only a few years ago.

[Q] One S vs Sensation H/3G

Hi all,
I own a Sensation XE and my girlfriend owns a One S. I'm on ARHD custom Rom and she is on stock jelly bean. We are both on the same network.
The HTC one S is constantly changing from H to 3G whilst the Sensation stays constantly on H. When I say it is constantly changing I mean its every second or two non stop.
Is this a cause for concern? Is this eating into her battery life at all and does anyone know what the answer as to why it keeps doing this?
thanks guy

The H/3G switching is, as far as Ive read, a bug and it doesnt actually switch. Its just the icon thats messed up.

I heard two versions about the switching:
1. its because of energy saving, 3G needs less power then H(SDPA/PAP)
2. 3G is when your mobile connection is running idle, only If your phone loads data (mails or sync etc.) it's switching to H

From my experience the 3g/H switching is normal as long as the phone isn't loading any data: 3g is the idle state and when the phone needs to load data it switches to H and when it finishes it turns back to 3g.
But sometimes it happens that you need to load date (e.g. load a web page) and the phone continuously switches between 3g and H and no data at all is loaded (e.g. the web page's loading doesn't proceed): this is a bug. I have this on stock EU 4.0.4 (firmware 2.31 and radio 1.06es).

Now to add my two cents... From what I know about this (told by viper team members) is that on T-mobile's roms they disguise this particular behavior and it is actually normal. As NQNH said, 3G is idle and H is when you're using the connection.

Thanks all for the responses. If this is the case, is there anyway to find out what is using data every second or two?
Does anyone elses' One S flick constantly between the two?

[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

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

OnePlus One mobile network keeps getting disconnected when set to LTE recommended

I'm facing an issue on my OPO mobile where, if I set preferred network as 4G LTE, I'm getting only 3G connectivity that keeps disconnecting and connecting again(start->H->H+->H->disconnected) and cycle repeats.
The customer care person just keeps telling me to restart my mobile and that there is no issue at their end .
I tried to take the logs but I'm not able to make much sense of it.
ADB radio log: http : // pastebin . com / HwV0uhzs
Mobile details:
OnePlus One A0001
Android version: 6.0.1
Cyanogen OS version:13.0-ZNHEAS2JK
Kernel: 3.4.110-cyanogenmod-g7808b1e
Build number: MMB29X
Operator Details: Airtel India
Can someone please help me out here as my battery is getting drained quickly as well if I set the Preferred network to LTE recommended.

Don't expect constant strong 4G signal from Airtel India ! Those Airtel 4G girl ads are all myth. Heck not half the places shown in ADs are covered in 3G and they are saying 4G, I am too on Airtel India 4G and I have OnePlus One and Samsung Galaxy S6 .. Both doesn't maintain regular connection with 4G. And if sometimes they do connect I face lot of Drop Calls..

Yes but this is different, the network gets disconnected almost every 10 seconds even when kept on top of table without any movement. This never used to happen previously also.

Yes it is same .. What happens when you keep 3G selected ? I am pretty much sure if you select 3G it will not disconnect.
You can also try 2G for checking ..
When I keep mine on 2G I get best signal without any call drops ..

Yes, you are right, it is working perfectly fine on 3g setting. But this never used to happen until few weeks back. 4G was working fine till then. I had installed a couple of OTA updates, however, i'm not sure if that is the cause. Do you know if there is a solution for the issue and if this is a mobile issue? Customer care is really not helpful and they closed my 2 complaints telling me to restart the mobile.

When I keep mine on 2G I get best signal without any call drops ..

I think its a carrier issue. However I'm not able to understand the errors in the logs

Yes, you are right, it is working perfectly fine on 3g setting. But this never used to happen until few weeks back. 4G was working fine till then. I had installed a couple of OTA updates, however, i'm not sure if that is the cause. Do you know if there is a solution for the issue and if this is a mobile issue? Customer care is really not helpful and they closed my 2 complaints telling me to restart the mobile.

Don't worry buddy there is no issue with your Phone, I live in Ghaziabad UP and 4G works very bad here same as you described your problem, however as soon as I visit my relatives in Delhi, Laxmi Nagar area or to ITO side. 4G works like a charm with max speed of around 38MBPS download speed and no disconnection of network and no call drops.
One thing you can do is raise a ticket in Airtel as ask them to send a technician to your house and check the Signal strength around and in your house.
I had raised same type of ticket with Airtel and a field technician came to my house with weird gadget in his hand and he checked thoroughly my entire house and there was many blackout zones in my house where there was no signal.

I did a bit more research, and it seems the same SIM does not show 4g on another mobile as well. One of my friends next door who also has an OPO with same operator doesn't seem to have any issues even when both mobiles were kept together. So definitely something wrong with the specific connection.

Okay here's the perfect explanation as to why that happens.
3G has two classes of Network HSPA = 3G/H and HSPA+ = H+
H is the pure 3G while H+ is 3.5G that is an advancement of 3G which is better. Its okay if your network keeps switching between H and H+ it is quite normal all the time and completely depends on your service provider.
If you are losing internet connectivity when this happens means an issue persists.
When you switch to 4G/ LTE band your phone keeps searching for 4G network thus frequent drop of internet connectivity happens if it gets no 4G service. This also means that your area is not 4G supported yet. That means your phone keeps trying to switch to 4G because its preferred but upon finding no nettwork or weak network it keeps falling back to 3G and repeats the same process again. Hence keep it to 3G only.
Personal Advice - Airtel is sh*t change to something else. In Bangalore I used to get 1-3 mbps 4G speeds but on Vodafone I get about 28-31Mbps. They also said it'll be increased to 91mbps by next year! just an advice.

Thank you dwaipayanray95 and Abhinav_Rakesh,
I will probably drop an email to airtel once again and see if it gets resolved. If not, I'll shift to Vodafone.
Desperate times call for desperate measures
