Hi! I have been browsing the Nexus One forums for a while now, but I seem to have a strange problem.
I had a Nexus One that was working fine, but there was a piece of dust under my screen. It switched to HSDPA, and I had none of the issues that I have now. I sent it to HTC, but they didn't want to repair it, because it was rooted. I think they flashed something into the phone, because ever since the internet connection is very buggy. 3G (UMTS) didn't cause any problems then, but now if I hold my hand at the bottom of the nexus, connection indicator lowers (Cell Viewer: ranging from -1 to 8). When I hold the phone up int he air the connection varies between 14 and 24 (UMTS). The phone doesn't switch to HSDPA AT ALL!
I tried the hsxpa-tweak in build.prop, but it didn't help. I am using Cyans latest stable. I have wiped, installed stock, upgraded to cyan again, and tried staying on the stock rom, to no avail.
Is there something really stupid that I am not seeing? Or would it mean that the transporter has damaged my phone antenna by dropping it? :O
What makes you believe you're not getting HSDPA? Have you tested the actual speed of your connection? Keep in mind, on an unrooted Nexus One, your signal indicator will always show 3G even when HSDPA is active. It only shows the H when you're using a custom ROM.
Also, the signal fluctuation when covering the bottom of the phone is well documented at this point. It's normal.
HSDPA is only active when the network deems you need it, it'll just sits on 3G all other times.
Funny..I'm on HSPA all the time when on 3G..never saw UMTS not one. Yet on a cliq I saw UMTS...

I used Cell Viewer to test signal type. I was consistantly on HSDPA before it got sent in to HTC.

Also, check which Radio Firmware you have installed now. If you have 32.26.00.24U_4.04.00.03_2 installed, try downgrading to 32.24.00.22U_4.03.00.21_2.

Hmm... I've had a look at that thread, thanks for the pointer!
Too bad I'm in Europe . I changed to US, JAPAN, AUS and EURO, but it didn't help . I'll try the same with the .03 radio. I've flashed both the .03 and .04 radio's before, but not together with the instructions at the end of the mentioned thread.
Been having issues with my phone where once it while it would disconnect from the network (happens daily). I live in Hong Kong and am using 3 as the network here, and am running RomAur 2.31 with PureXAudio.
(1) Has anyone had those types of issues?
(2) Are there any flashable RADIOs? (I remember updating my radio version on my previous Nexus handset, but haven't seen anything like a radio release here in the forums)
Thanks!

Yes, but not with that ROM you mention (well actually I am using 2.3), I had constant issues as you mention with only .350 ROM. Is anybody else asking the same question as you for that slight upgrade from 2.3 to 2.31?
Not aware of any other radios available for this phone, it is too new. The radios that you see around are typically created by the phone manufacturer, and as time goes on you end up with a great choice of radios to flash with notes about the good and bad people have discovered along the way.
Why did you update the Nexus radio, where you having similar issues or issues with your cellular provider?
All I can recommend is to factory reset and re-install the ROM, of course make sure you back everything up so you can restore it afterwards.

So, when you say this are you getting the X through the red network strengh indicator at the top, if not then your phone is not disconnecting from the network, just switching modes or towers

Hi,
I have a weird problem with my S4.
At work I have some areas with really bad coverage so sometimes the phone can stay for a few minutes (or even say 1h) out of service.
This is all normal. The coverage sucks, the building is weird, not problem here.
The problem is that when I go outside where the signal is normally full it does not register back to the network.
Even more it does not even go to "emergency only mode". On a few occasions I arrived back home (10Km + drive) until I realized people can't call me because the phone is out of service.
What is even weirder is the fact that on some occasions, even though the (no service) (/) sign is displayed mobile data works just fine.
My previous iPhone did something similar too - it took a while for it to recover signal after exiting the coverage black spots but never more than maximum 5 minutes.
To me it looks like a radio modem issue and maybe this is aggravated by the fact that my carrier uses the same 2100MHz frequency for both Data and Voice.
I would like to know if any of you have experience anything like this or if there is some app available that can monitor what's happening.
what network and firmware you on and wich s4 variant:thumbup:
Sent from my GT-I9505 using xda premium
I9505XXUBMEA I9505OXXBMF1
It's Europe standard i9505.
Network is Digi.Mobil Romania - but I doubt it's relevant since it can't get even emergency only (other networks).
so... any idea?
Android needs to work on it's notification. No Service and the reception bars only gauge voice coverage. You can test this out by using Service Mode to do a PS Only (data) attach instead of the standard PS + CS (voice) attach. It'll say no service, but data will be fine.
Emergency only, is when there is coverage from other operators but not yours. No service, means your way off the grid.
I've noticed the issue you describe and it's only on some firmwares. Try a newer one and see if you still have the same issue. But you might notice a drop in your battery life because your phone will be scanning all the time. If you're happy with no coverage at work, best to just turn it off and then turn it on when your outside.
Best option is to tell your operator about the lack of coverage. There's someone in charge of stats who get's beaten every time you drop a call. You'll get extra attention if you've got other businesses around you, so let them know that too.
Thanks for the reply.
I am already on the latest firmware and I noticed the same behavior on the firmware before this one.
Unfortunately I can't try out other modem versions (from other FW packages) as that would void my warranty.

but...what about reboot phone? i know isnt funny but until u find a problem u can just reboot ur phone while u are going out from ur office...or just try to enable and disable airplane mode
Of course reboot works but I am looking for a solution, not a partial workaround.
The most annoying problem is that if I forget to reboot it when I leave work it will not recover network connectivity even if I am in areas with very good coverage, areas where you would expect your phone to work.
It looks like when it decides to give up it does not try again. It is very weird that it also drops the signal from other networks (the "emergency only") even if it's well in their coverage areas. I guess I will have to switch phones... Even if this issue was present for the iPhone too it never took more than a few minutes for it to recover on its own. And I'm not an apple fan
Just to do some brain ecercise...do u keep in power save when u are out of signal ? Its possible that disable check after few tries
Sent from my GT-I9505 using xda app-developers app
It's not in power save. I only use that function in case of battery emergency.
Same problem here
Hello, I have the EXACT same problem here. I am in Argentina.
Now, I've been in the USA for a few weeks, visiting, and while my phone was roaming, I didn't have a single problem with my phone.
Since I came back, 3 days ago, I haven't had any problems in Argentina, either.
Is it possible that something got activated when the phone was registered to another company? (it was AT&T i believe)
If that's the case... maybe you can try putting a sim card of another company and see if you still have the problem?
Please let me know if you still have the same problem or if you got it solved. I would love to know something more scientific about all this.
I don't know if this is relevant, but my compass is off by about 30 degrees. Maybe my phone is defective?
THANKS FOR ALL YOUR HELP YOU CAN GIVE ME WITH THIS

Hi I have similar issue,
My phone says its out of service or no signal or no network also I checked my sim card in other phone in the same place and it is fine. The i9505 model in ireland meteor provider was running ok until deicided to give a try to another network operator, when I changed the sim card it didnt only catch up the signal from new network provider but also it refuses to catch the old network provider. Funny thing is that I am receiving 3G but no signal bars and no service sign is beeing displayed. I am running latest official BTU (UK) firmware, the phone was never rooted, altough I had to remove the simlock and instal unbranded firmware. The phone worked fine with the newest updates for a month and now I am facing this trouble.
No factory resets nor installing same radio (couple of times) have helped. Also I used odin to instal same firmware (as it has locked bootloader) so I cannot revert back to other stock firmwares, but still no joy.
hope that someone faced the same problems and describe how to solve this issue. thanks
I own a Verizon Motorola Razr M, bought in ebay to an US seller. I am in Spain and I use Movistar SIM card
The phone came with stock JB 4.1.2, and therefore I could not unlock the bootloader.
I started using it, but it had a problem that I am not been able to solve so far: after some hours of use, with no problems with GSM and data connections, it suddenly looses both connections, although the signals on the status bar still appear. I take care that signals have gone when I take the phone to make a call or surf the web.
I have tried the following procedures:
Change the net settings to GSM/UMTS
I rooted the phone with motochopper 1.1.2 exploit
I installed Safestrap 3.12 in order to be able to install other available locked compatible roms.
I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

The problem also seems to become worse with the use of the phone: at the beginning, coming from a factory reset, It can last some hours before the problem occurs. But since it happens from the first time, it happens more and more frequently and the phone can not be used any more. It seems that there could be a software issue.
Another try disabling fast dormancy
I´ve just disabled fast dormancy, because my operator Movistar apparently does not use this technology.
For this, I have modified 3 lines from build.prop system file, as indicated in another site.
The 3 lines are:
ro.mot.ds.fastdormancy.disable=true
telephony.lteOnCdmaDevice=0
ro.telephony.default_network=3
Having fast dormancy enabled when your operator does not support it, seems to drain battery, and could cause other problems. That´s why I´ve done this. I have used root explorer apk from Google store, it is free and it automatically creates a backup of build.prop file when you modify it.
I keep the fingers crossed, let´s see what happens.
Fast dormancy: yes but...
After some days using the phone with fast dormancy disabled (for this, I also added this line to build.prop: ro.ril.fast.dormancy.rule=0 ; I read this for ICS Roms, I do not know if this command is also valid for JB, any comment will be welcome), I still get some cuts (less I would say), but at least the phone tries to restart the connections. For this, I have also installed the apk from Google Play called 3g reconnect.
In any case, any comment would be appreciated.
Issue not solved
I still get data and voice disconnections when I use GSM/UMTS or only UMTS modes. They occur ransomly, and they also occur as soon as I use a WIFI connection. I can only use the phone on GSM only mode, which is frustrating.
Any advise?

Hello,
I have tried both: using *#*#4636#*#* or using the usual phone settings. Sometimes I have also checked that the changes made with the usual settings appeared also dialing *#*#4636#*#*.
Yesterday evening, I tried selecting global mode instead of GSM/UMTS and it seemed to work for some hours, but today morming, the problem occured again. So far, the unique way I have found to avoid connection cuts off is using GSM ONLY mode. I have to say that I have tried with 2 different SIM cards but the result is identical.

Did you select the 3 dot menu & mess with the "band" settings?
---------- Post added at 07:08 AM ---------- Previous post was at 06:56 AM ----------

I did that once, and all the signals disappeared. I restored the phone with RSD Lite, that appeared to be the unique way to have again signals working. Now I do not even dare touching these 3 dots.

What booby a trap? How many step into!
I don´t know if I am understanding you. I did that once because I did not know what else should I do to solve the problem. I saw that there was the possibility to choose theoritically between US bands and Cellular, and I entered in that menu. It is not so stupid to try that if you have already tried 100 other ways.
In any case, anybody has an idea about how to solve this problem? I´m sure I am not the unique person having this issue with this phone.

You are saying the problem is now still there. Yet the radio partition is fixed. Please restate what has been fixed with the rsd flash & what remains unfixed.
Well I think I have fixed and solved the problem: I initially copied the APN settings I had with my previous HTC Sensation, because the phone operator was the same (MOVISTAR), the SIM card too, and I have not moved. In these APN settings, the proxy was "undefined" as well as the proxy gate. I wonder if the radio stucks looking for a proxy each time or whatever. I tried yesterday with completely different APN settings, with a concrete Proxy and a gate... and now I have not had any issue in the past 24 hours. I will still wait a couple of days to see if that was finally the reason.
Which in any case would be silly, because I just applied what was working OK with my sensation, but...
New APN settings: let´s see

After several days, the problem is still there. After setting new values in APN, it happens less often, but it still happens. I have to switch to GSM only mode.
2 days ago, I was surfing the net at quite high speed with no interruptions, for half an hour. I then shutted off the screen, on again some seconds later, and the connection was blocked, I had to restart the phone. It has to be a software issue.
I finally sold the phone
After concluding that I could never get rid of this problem, I sold the phone, informing that he would have to use mainly GSM only connection. Great phone otherwise, but with this issue.
This sounds like a Baseband Issue.
Europe I have found baseband:
sm_bp_101031.027.32.81P to be the most stable so far, with no H+ support though.
But most Carriers in Europe don't have H+ or LTE.
That baseband is part of build 9.8.1Q-66
Which can be all downloaded here:
http://sbf.droid-developers.org/phone.php?device=8
The baseband from 98.16.1 had H+ support in Europe but connections dropped like crazy.
Same with 98.12.4, we remedied that with Aussie Radio at the time.
Maybe this may help some International users with Data and GSM Loss

I'm on 9.8.1Q-94-1(98.30.1.XT907.Verizon.en.US) and wanna use it in Germany. any experiences with the radio compared to the suggested one. Or is there another way to boost the performance of the razr m? Compared to my razr I the signal and data quality is really poor...
edit: my baseband-version is: SM_BP_101032.021.32.80P
edit2: ok... now i've flashed several basebands... and the behaviour of the phone is always the same... with the australian baseband of xt905 it wasn't possible to get an hspa-connection. dunno if its enough just to flash the radio-fw?!?!?
so is there an other way to get more stability in my region? i tried to flash the radio from razr hd retail germany. but i think the razr m don't like it when I fool around. actually I love the mobile, so i don't want to make it angry... your suggestions are very much appreciated...
Hello everyone!
I am having a very hard time diagnosing an issue with my Nexus 6P. Android 7.1.1 Angler-03.78 Build: N4F26T on AT&T unlocked. My network keeps dropping consistently. It works fine for about 5-7 minutes after a reboot or after toggling Airplane Mode. It goes on to attach itself to LTE and then subsequently drops to HSDPA/3G and then just outright loses network. It intermittently then comes back but usually hangs on to HSDPA/3G and the voice quality and data speed are just terrible.
I tried the SIM in my old Galaxy nexus (which doesn't support LTE unfortunately) and the network didn't drop. So I am convinced something is going on with the phone. This issue crept up this last Monday (03/26) and has been going on ever since. Has anyone had similar issues? If not, could anyone tell me how to diagnose this issue before I have to send it to Huawei? Because I am not very keen on sending away the only proper handset I have.
Thanks
I had a similar problem on Cricket, which uses AT&T's network. I never had good cell coverage in my apartment but it suddenly got so bad that I could only make and receive calls in certain rooms. Cricket wasn't able to diagnose the issue and I ended up switching my service to Project Fi. The problem completely went away. I now have a strong cell signal with full bars everywhere in my apartment. I'm not sure that sending your phone back to Huawei will actually solve anything but good luck.

Oh, I can't switch from my carrier. And this particular issue just started occurring this week. I have been reading a few threads with different radio versions. I wonder if that will help.

This is a known issue just this month I experienced it myself, Try flashing different radios I was on 03.78 and had signal drop issues 03.72 and 03.75 have had the best results.
I flashed radio 3.7.5 and it did zip for me. I was on Sprint where I never had any problems and switched to AT&T when I got the 6P and never got more than half the bars strength when the service was actually working. After I switched to Project Fi I am usually on the T-Mobile network and get full bar strength 100% of the time at home. If I use Signal Spy to manually switch to Sprint I still get full bar strength in every room in my apartment. This is with the exact same radio that I had problems with on AT&T. I don't know if the 6P doesn't play nice with certain networks or if those networks provide inferior coverage but Verizon users have had notorious problems with this phone that caused Google to issue a separate radio just for them. Verizon customers are the ones who claimed to benefit from flashing radio 3.7.5. I have never heard of that actually helping anyone else and it definitely didn't help me. If the problem is partly with your network then sending the phone back to Huawei won't make any difference. You can try flashing a different radio but in the end you might have to switch carriers and if you can't do that you might need to switch to a phone that your carrier actually recommends.

After I switched to Project Fi I am usually on the T-Mobile network and get full bar strength 100% of the time at home. If I use Signal Spy to manually switch to Sprint I still get full bar strength in every room in my apartment. This is with the exact same radio that I had problems with on AT&T. I don't know if the 6P doesn't play nice with certain networks or if those networks provide inferior coverage but Verizon users have had notorious problems with this phone that caused Google to issue a separate radio just for them. Verizon customers are the ones who claimed to benefit from flashing radio 3.7.5. I have never heard of that actually helping anyone else and it definitely didn't help me. If the problem is partly with your network then sending the phone back to Huawei won't make any difference. You can try flashing a different radio but in the end you might have to switch carriers and if you can't do that you might need to switch to a phone that your carrier actually recommends.

It's strange because this happened just this week. It was fine before this week. Everything worked, I got proper signal strength and the connection never dropped. Now on my commutes I can see there is no network when I am driving, no maps, no spotify nothing.

Okay, I guess that's what I am doing today. I haven't modded my phone in any way, I am still on stock android. I am going to have to start by unlocking bootloader and flashing TWRP.
Good luck. I was in the same boat. It just stopped working but there was no Rom update that could have caused a problem.

Where do I find the old versions? This thread doesn't have the old versions anymore. 03.79 doesn't resolve the issue.
EDIT: I used 03.75 and that doesn't do it either. Time to try 03.72. I am so disheartened.

Nope, no luck with 03.72 either. :crying:

Why not go to AT&T first, let them know about your issue and have them provision a new SIM for your phone (free). I seriously doubt a different radio is going to solve your problem, but if you want to try there is a dedicated thread in General for flashable bootloader/radio zips, but you would be better served installing ADB/Fastboot on your PC and using fastboot to flash them yourself. The latest radio is 03.81 (from 7.1.2) The stock image files on Google contain the radio and bootloader img files. If the new SIM doesn't fix it, you may end up backing up your data and doing a factory reset.

Okay the latest factory ROM didn't work, I did a complete wipe and a factory reset. I will go to AT&T tomorrow and see if a new sim helps (I doubt it because this SIM works fine in my backup phone Galaxy Nexus but I can't verify LTE with that).
I don't know what my options will be after this. I feel like I am spending more time maintaining my phone instead of using it. Just disappointed, that's all.

Yeah, I found it. Thank you. None of the versions helped though
I've been experiencing signal problems when downgrading which is not your case. But I got it solved by performing a factory reset. It's fairly straightforward once you have backed up your data. Worth a try?
Similar problem here I think I have found part of the problem
I have been having a similar problem ever since a recent update. I have tried everything found in this post. Recently I tried turning off my wifi and noticed the problem seems to go away. I have done a few searches to see if anyone has reported no phone with wifi on, none of the results so far have been very helpful.
Since I don't want to be without wifi, I have gone into the developer options and turned on cellular data always active, to see if this helps, so far this is working for me.

I did try that but it didn't work unfortunately. I called up Google and they sent me a refurb which was DOA but then later they sent me a new one which works just fine. So it was definitely a hardware issue on my old phone. I don't plan on updating my software because I just want this phone to work like a phone.

It happened either way. Wifi status didn't affect my issue. It used to die out completely. Google just sent me a new replacement (after a DOA refurb) and it seems to be holding. But I am not upgrading to 7.1.1 because I feel the issue might crop up again. So I am going to stick to 6.0 for now.
Update on my status
So far having wifi off has worked, until I ran Waze and then both GPS and Networking down till I quit and turned Airplane mode on and off. The previous change to Developer setting did not work.
I have been debating going back down to 6.*, has anyone had good results with this?
