I wanted to start this thread to discuss making and receiving phone calls on AT&T's 3G network. I find that making and receiving phone calls while connected to 3g or HSDPA is very unreliable on my Fuze. The phone seems to always connect to H whenever there is any signal available, even if the signal is very low and unreliable.
I will sometimes recieve a call while connected to H and the person cannot hear me at all. I'll look at the phone to see that the H signal strength is very low. Instead of smoothly switching to Edge, the phone completely loses signal and drops the call. After having no signal for around 10 seconds, it will then reconnect to Edge and have 2 or more bars of service. Why couldn't it just switch to Edge without dropping my call? Any why hang on to an HSDPA connection if signal is unusably low?
I see other AT&T customers with 3G phones (Bold, iPhone) and they don't seem to have this same issue. Their phones can remain in 3g mode and work just fine. My only choice seems to leave 3G turned off, but switch it on when I need a fast data connection (a terrible solution).
I used to have Verizon and they just connect you to both their 3g and 2g networks at the same time, you can even see 2 signal meters on most phones. They use the 3G (EVDO) for data and 2G(1xRTT) for voice or data, when 3G is unavailable. Why can't my Fuze do the same thing on AT&T? Clearly, 3G doesn't penetrate building as well as 2G and the phone needs to use both, seamlessly, to work properly.
Just for background, I am using a Fuze with the latest EnergyROM and Radio 1.14.25.35 and matching Rilphone.dll. I have noticed this behavior with other roms and other radios also. I can't remember how stock worked since I haven't had it in such a long time.
Does anyone else notice the same behavior as me and does anyone have any ideas on how to improve the way the phone manages 3G vs Edge during phone calls?
Thanks in advance for anyone who can help me understand and resolve this problem.
different radio
Drop into the ROM section, hit the radio thread. I found better luck dumping the stock radio on the Fuze, and installed a different one.
Any particular one that you recommend? Ideally, a radio that doesn't use 3g unless signal is reasonably strong would be best. Ive tried all of the official Fuze ones without any change in the behavior I described at all. Based on your signature, it seems you are currently using the same radio as I am...

I found the newest Xperia radio (1.16.25.48) to be very satisfactory as far as signal strength goes - in fact I had more bars of 3G and dropped a lot less calls because of it. However, you need to be Security Unlocked to flash your phone with that radio. The only problem with the Xperia radio I had was the pitiful GPS accuracy.
sopranos16 where are you located? There are a few cities where users have been complaining about the 3G network. NYC/Northern NJ and San Fransisco are two that come to mind. Check on howardforums.
I'm now using a Fuze because AT&T shipped to to me to replace my Bold which will drop 5-15 calls a day in NYC. I don't believe it is a problem with the Bold, I have other lines with 3G that have problems. But this is the solution they offered so I'll try it.
You cal also check the at&t support forums as there are plenty of complaints there too. I just got the fuze and haven't really tried it yet. See what happens on Monday.
I'm located in central New Jersey: Monmouth County. Edge coverage is pretty good but 3G tends to always have a weaker signal strength and occasionally drops out, especially indoors.
Well the first day in lower Manhattan and not one dropped call. I'll let you know what happens later in the week.
bump
soprano, did you try the xperia radio? Let us know, I have had this issue for a while now...and your explanation was on the head.
Think I may just go ahead and security unlock my phone.
Hey, I'm having this weird problem with my 3G connection/data connection. If I end up loosing a 3G connection during a call. The only way to get it back is to end the conversation. To further explain... If I hit a spot with no 3G, then go back in a 3G spot, it won't come back on. I still have a good signal and i can talk but there's no E, G or 3G showing. While my phone is in this state I'm unable to browse the web,, it says no data connection which is odd because i obviously have a connection if I'm on the phone...3G starts to come back on As soon as i press end call. It instantaneously goes to E, then G, then 3G. At that point if I make another call, I'll still have a 3G connection and my phone works fine, i.e. i can browse the web and talk as usual. If I hit a spot where I loose 3G again (while in a call) it won't reactivate, I can continue to talk but I can't browse the web. No E, G or 3G showing (just bars with good signal) and it won't go back to normal until I end the call. Any suggestions?, thanks. unlocked bootloader, completely stock, not rooted running 2.3.3
Its an issue but not an isolated issue. I've experienced this as well, on both T-Mobile and att phones. Maybe LTE technology will help with better signal transfer than 3g.

Same thing here.
Just for the heck of it I called t-mobile to get my original sim card activated. It's an oldie from 2004. They said it should be turned on within the next 24 hours. I don't ever remember it happening with any of my other phones while using the older sim. Maybe there's a connection,, it's worth a try, I don't have anything to loose. I'll post my results.
i was under the impression that you can't surf the web and make a call at the same time. since day 1 my phone has always turned data connectivity off as soon as i make a phone call. i thought its supposed to be that way lol. it isnt?
EDIT:
just did some testing. on 3G i can make phone calls and surf the web. on E, i cannot. i leave edge on all the time to save battery (dont need 3g to check emails), so i guess i thought its normal for data to cut out haha.
tmobile and ATT networks are not setup right now to hand a call from GSM back over to 3G during a call. if you are on 3G during a call, and lose 3g and go back to gsm, you will stay on gsm until the call ends. then the phone will switch back to 3g.
this is done on purpose by ATT and tmobile, the thought is that they will enable this hand off direction once 3g is widely covered. but since gsm footprint is larger than 3g, they set it up this way. its annoying, but normal.

Roger P, I'd hit thanks for your answer but I don't see the thanks button to click. For me it's a huge deal to have some closure on the matter. As we all know, it sucks when you loose confidence in your phone. Don't know if it's a web site etiquette thing and that's why I'm not seeing it. Either way, thanks a lot. peace
It depends on the 3G carrier setup by your operator. For example, my operator uses 2 carriers for 3G service, one is data only carrier and the other one is shared between voice and data. So sometimes 3G data connectivity goes away during a call because I was connected to a data only carrier and sometimes I keep using the data connection during the call because I was using a shared carrier. I don't know if this is the case for T mobile.
Hi everyone
I have an issue, when I'm on my office the network signal isn't strong so when my One S go to "NO NETWORK" after it don't go back to network.
When the situation is this I can't go to airplane mode, change operator (from settings), the only thing that work is shut down and restart (no fastboot).
Anyone else have this problem?
Maybe is a software bug?
I have the Paul recovery and su
EDIT: More info
That don't happen every time that the phone go to "no network".
I think that happen when it a weak signals and are under 2G network.
there are users with similar issues, I only use 2G networks. If i want to do a bit of browsing i will manually change to auto mode, but other than that i always leave it at 2G..
hopefully there will be a radio upgrade soon that should fix this problem...
I'm suffering from the same behavior!
I'm still with the original ROM with no ROOT so I contacted HTC about it yesterday.
I got today their reply today:
"On your phone, kindly go to settings > mobile network > Network mode, kindly change the network mode and check how the signal will respond to each of them.
-Kindly try a different SIM card, to check whether the issue is with the SIM card or the phone itself.
- Soft reset for the device by pressing the power button for 10 seconds.( Note that soft reset erases any unsaved data.)
- Safe mode(which disables any 3rd party application which might be causing conflicts for your device.) for the device by Switching power on , then press and hold volume down when the quietly brilliant logo appears on your screen, you should see 'safe mode' text written on the bottom left of your home screen.
- Factory data reset, kindly backup your data before proceeding with this step please as you will
lose every data on the phone's memory.
Please go to Settings > storage > Factory data reset > Reset phone."
I haven't done anything yet and I didn't notice the 2G issue you mentioned.
I also haven't got this issue for the last 48 hours but did encountered it twice (!!!) on Sunday while driving across the country.
I'll try having the Network on 3G only and see if that matters although the area I leave in is not with good 3G reception.
GSM is 2G
WCDMA is 3G
i use GSM only unless im using the net
I'm aware to the 2G-3G difference
I'm on WCDMA preferred so my phone tries to be on 3G.
My phone also suffers from the 3G<->H data connection jumps while the desire wasn't having any with the same provider (different SIM of course).
sorry, My bad !!
i understand what your saying now
I cant confirm much as my provider doesnt have 3g signals in my area
If i try to use 3g at my home, I have 0 bars thats why i always use 2g
I switched to 3G only (since I have most of the time 3G and surly wants it for the data rate).
I know I have on my way to work and back places with 2G only but I'll give it a try for the coming days and reply.
BTW, just few minutes ago, while having 3G active for sure (before the 3G only switch when it was still on 3G preferred) I couldn't make any phone call although I had 4-5 bars and data connection was running.
Two days ago I tried to change my sim.
Before I had a cutted microsim, now an original microsim and the issue is still present.
Yesterday I had this problem only in afternoon, not in morning and only where the switch from no network -> 2G -> 3G is very very frequent.
In all other times out from office I never had this issue.
I also changed SIM with no help, stayed in 3G network only with no help and observed that when such a network crash happened, GPS reception is also disconnected!
I had no coverage situations with the 3G only mode which recovered, but what we are facing is a network "crash".
Our situation was escalated to technical support of HTC after I wrote them all the data and they tried to solve it over the emails w/o success.
Same problem for me. I tried only 2G, 2G/3G, only 3G, but no way..same problem..i hope an update can solve this..
I just bought my new One S from T-Mobile yesterday and everything appeared to be okay but now I can barely get it to hold a signal. Forget throwing it on GSM only because it will have signal for a whole few seconds before dropping it. I also am having Wi-Fi issues as well. It just intermittently drops the connection there as well... Not a great start!
whether im imagining this or not im not sure, But for me it seems like, When the Network signal increases, the WiFi signal drops, And when the WiFi signal Increases, the Network signal drops...
ive been noticing this for over a week now, So it cant just be coincidence..
I dont think my (or our) handset is faulty, I just think theres a pretty big bug in the ROM, and no matter if you switch ROMs they all use the same base at the moment..
This phone has great potential. But HTC need to be listening to us and release some updates. !!

I noticed the same exact issue last night. My phone will go to full signal before dropping whichever connection. I'm just glad this phone can handle staying on 4G without draining the battery like crazy although I can only imagine how much further it'd go with 2G.

Exactly the same here. But I had a different WIFI issue - WIFI won't drop but stay connected - even if I am far away off the AP.

that one is also a known bug.
On top of that, WiFi will sometimes stuck at "error" status with no ability to turn it on...
All probably related to the same network chip driver or "Radio"...
I have same network reception problem. When I am in a poor reception area it loose reception all of a sudden and takes a while before getting the signal back. I often toggle flight mode to force network detection. I also think the reception bars don't reflect reality; sometimes it seems I have good 3G reception but cannot surf the web. I fear it is a critical bug. The phone seems unable to handle correctly signal fluctuations and protocol changes (GSM, 3G, HSDPA).
I'm colletting more data about this problem.
First of all I don't have any wifi issue, or maybe I don't see this.
I have a modem with N standard and one with G standard and nothing of this have issue.
About the network issue in this days I never have, only when I'm in office and the signal suck a lot.
Q: Anyone that have Tmobile/mod rom with 1.70 RUU have this issue?

I don't have wifi issue at work with a powerful 802.11n network AP but experienced occasional fake/unstable/disconnect wifi at home with a poor AP which operates on no-one-knows-but-definitely-not-N network. I don't really bother too much cos I can always turn wifi off and on to reconnect.
In terms of 3G/H signal switching problem, yes, a bit annoy especially when playing online game on 3G but accessing internet is fine just need to sometimes wait a bit longer.
I am on international unbranded version in UK.
I've the same problem in France about 3G/2G and wifi on international unbranded version.
I just got a new xperia z5 and I'm using it on att but my phone signal is always showing zero bars.
I get data but incoming calls sometimes don't go through or go through after 2-3 rings.
The signal shows bars when I make outgoing calls but then disappears quickly thereafter. I thought it was maybe WiFi calling enabled but I don't even see that option anywhere in my phone and this happens when WiFi is off too.
This is a very strange phenomenon and can't find any answers anywhere. There is also a small circle with a line going through it on the notification bar, not sure what that is.
Does anybody know what's wrong ?
Small circle with line indicates "do not disturb" mode is active. Its under sound or notification settings, can't remember which. For signal status, check APN. Also, is your IMEI for this phone the Z5 one or an old AT&T phone? If AT&T has your IMEI for the Z5 it will register on their system as an old phone since they don't have Z5 in portfolio. I had to give them an old IMEI off a LTE device from AT&T because it was showing as a P series phone in the system and I was only getting 3G, no LTE.
Just noticed the small circle was for sounds. Thanks
I am getting LTE which is weird because it just not showing any bars on top but the lte works.
No one else has issues with their signal bar on their xperia z5?
This is really strange and can't figure out what's wrong with it.
No issues with the bars per say but definitely issues toggling networks, especially with 3G prefered mode. When 3G prefered selected I only get mobile data when H+ icon shows next to the bars. 3G, 2G and H don't work! The phone sometime takes up to 10-30 seconds to toggle to H+ and be connected. This drives me nuts! Do you guys experience this as well? Today I got no signal at all (no bars, nothing) for two hours.
Stamina is off and I have proper signal.
SFR France btw.
Try to toggle LTE off.
This sounds like an issue I had with a data only SIM in Japan with my S6, except no 2G network was the cause I think, not sure what would cause it on AT&T.

It's strange because I show full bars when I make an outgoing call or right before someone calls me, all the bars fill up. But it takes 2-3 rings on their side for it to ring on my phone.
And after the call it goes back to zero bars. But I still have the lte sign there.
Is there a way to update the gsm radio?
Same issue here (Z5 on ATT). I get one bar consistently when the phone is idle with the bars filling up when making calls, sending texts, etc., but I do get full LTE speeds and haven't noticed any other problems... I did look at my account, and the Z5 does show up as an "unknown device".
I tried changing APNs from "Attnextgenphone" to just "ATT Phone" but it didn't make a difference...

I am glad I am not the only one with this issue. At home I get one bar with wifi off and with wifi connected I get zero bars until a call is made or received.
I am located in NYC and have the 32.0.A.6.152 rom and the baseband is 8994-FAAAANAZQ-00029-16

Exactly the same here (FW and baseband). I'm in CO and I do sometimes get full bars outdoors, but it happens randomly... It's almost for sure a problem on ATTs end considering that they don't even recognize the device on their website.

Is there a newer baseband that we can upgrade to that will fix this signal issue?
Or de we have to wait till the marshmallow upgrade comes out.

Hi, it's a high probability that you are seeing bar fluctuations as you suggest because your phone is actually changing bands during this time, because the cell tower pushing your call etc doesn't have the signal strength to push LTE.
As for the OP if his LTE/4G shows higher bars as soon as he is using the internet this is a different issue, and strange maybe faulty hardware.
I would recommend you all go somewhere where you know there is good coverage, even with another phone if possible and see if you still have the same issue.

Mate I am not sure the phone suffers from signal issues, I have had most of the Z series phones, all have the exact same signal strengths for me at various locations, and the phone has better coverage than other manufacturers as well, when I compare to other friends in super low coverage areas
Hey @bigneeker,
Just wondering if the MM update has fixed your signal issue.
For me it hasn't, but if it did for you then it might be a region issue (mine was Singapore, but I flashed the MM update for Germany).

It didnt for me
I noticed it too. Sony xperia z5. I use the quick LTE toggle and when LTE is on, all my bars are greyed out, but when LTE is off and I'm on H+ and 3G then all my bars are lit up.

Same here. Also, whenever I lose signal or inexplicably switch to Edge, toggling the LTE switch off and on seems to fix the issue.
I compared the specs of the Z5 and the specific bands/frequencies AT&T uses, and the problem might be the frequency that they use on Band 12... I don't know.
I don't know about European carriers, but since T-Mobile uses a different band for its LTE, then that might explain why this issue is not that well-covered in the US (though I can't confirm that).

Hi fellow Honor8 owners,
I have UK Honor 8 32GB model purchased from Vmall.eu/uk. I came from an iPhone 5S and must say I'm loving the device!
Only issue I have been having is constantly, the Data signal keeps dropping out and I am unable to recieve/send calls and texts. It completely drops out for a bit then comes back. This happens very often.
Is anyone else experiencing any similar issues? I have the nano SIM installed into SIM slot 1 .
I will maybe give the SIM a clean and reseat it into tray to see if there is any difference.
otherwise aside from that issue it's been amazing! One thing I'm really impressed is with battery, I am getting like 6 Hours Screen On Time on each cycle! and I'm not such a light user. Great for £260 unlocked!!
:good:
I also have giffgaff. This also happens to me mostly at home. I disabled Carrier Aggregation which seems to help, but it still happens sometimes.
I have the same and set the signal to be 2g only while at home, as I am using home wifi. I get many more bars when I do that and its good for calls and text only of course.
Its a pity we are not able to activity switch mobile data modes depending on our location without rooting.

So I tried cleaning and blowing in sim slot maybe debri but no still had the same issue. But then changed to carrier aggregation off, that helped a bit but still had issue often.
Finally resorted to switching to 2G for Calls and SMS only and I am mainly getting full signal strength all the time!
strange.. wonder if it is hardware issue or can be fixed via update?
