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.

You missed the hoop with this one lol. Topic is not about this.

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.

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.
I am on my 3rd device in 3 days. First one was rooted, second one was not. This current one is also not rooted as well.
Unless I am very unlucky, I am going to assume there is a definite issue with the network configuration on this device. Status says I have 3 bars of 4G coverage, however I cannot connect to the internet at all.
Network Signal Info says I am on UMTS with a -93DBM, data is connected. However nothing will load. If I put the phone into airplane mode and then turn airplane mode off the networking comes back online. Speeds are slow though, barely able to perform basic mobile web browsing and watching youtube and such isnt possible. Too slow an too long to buffer.
This doesn't only happen at my house, it happens in other areas as well but it does happen constantly at home. I a not a heavy data user on my account, 1-2GB monthly, so Tmo says they arent throttling me. They have replaced the SIM every time with the devices as well.
Suggestions? If I cannot figure this out soon I am going to cancel my service as I cannot pay for a service and phone that just doesnt work. Tmo seems stumped. They just keep replacing phones since I am within my 14 day return/exchange period.
However, 3 devices all having the same issues sure seems to either prove the phone has an issue, or m general area of Tmo service.
I live in downtown Tempe, AZ.
Your wifi works?
I have the same issue in my house... I have a weak signal and 4g drops down to 2g which is terrible.... 4g downloads are 3Mbps, but uploads are under 100kps
I changed the network mode to wcdma only which helps significantly. 4g drops, but quickly returns...
Give it a try...
I'm having the same issue here in Orlando. I've had 2 phones now (first one was just a bad unit) and both have had horrible network connectivity and reception. I take my SIM card out and put it in my 2 year old MT3G and it gets perfect reception and fast data transfers while the G2x is choking on network transfers.
Go complain here in LG forum. This is software issue.

have full bars but cant download anything. just sits at waiting for data connection.
We really need a baseband modem that works better. My bars goes to zero then to edge and then to 3g constantly. Any time it switches between the connections then the the bars goes to zero and it says there is no conection. Also noticed that 3g connection fluctuates very bad while doing a speed test.

How are you getting 3g? Unless you meant to say 4g?

T-mobile only has 3g connection avaliable where I live, of course it says 4g on the phone but in reality it is only 3g.

I wonder if there is an issue with our network in Arizona?? I live in Chandler, and work in Scottsdale. my data times out ALLL THE TIME. Both here at home, and at work. Same with my text messaging. Literally, I do exactly what you do with the "airplane" mode. That's the only way to get my data and text working again (besides restarting).
Here are the issues I posted in the LG Forum:
http://www.lgforum.com/forum/boards/carriers/t-mobile/topics/few-issues-with-g2x#26861
(first issue posted is what you are talking about)
I dont think this is a regional issue. Downtown Minneapolis here, and I cant get it to stay on wifi or Edge/4g for more than a few minutes at a time. G1 has no trouble and shows strong 3g while my sisters mt4g shows full 4g. 4g/E symbol just flickers on my g2x leaving me with no connection. I can connect to wifi fine, but even with wifi sleep set to never it still disconnects every few minutes, and has to be toggled on/off to reconnect. Until toggling it just sits flickering 4g/E with no data connection.
I've never seen my Evo drop a E/4g/wifi connection and struggle to reconnect once in the year I've had it. My g2x does it almost every time I pick it up.
Did you try going into Mobile Networks in Settings and changing the mode to WCDA Preferred or something? That'll stop the flip flopping. That's what I have it on and that's what the phone came with out of the box.Also try Auto in that menu.
I have the opposite of the LTE dropping problem I see most people have. I can't get 3G, but my LTE works fine (well, once it spazzed out after a PRL update and would only do 0.5mbs on LTE). At work, where I know I can't get LTE, but could get 3G with my Note 2 (and we even have a repeater), I can't get data. If I go to the window where I can barely get LTE and reset my antenna, it'll get LTE, and when I walk away it'll flash 3G for a second and go out. I still get several bars and can talk and text fine. Everyone else with 3G is fine. After thinking about it I realized that in the month I've had the phone I've NEVER been able to connect to 3G in places where I used to be able to. It's LTE or nothing. I'd be more than happy with 3G if the alternative is to read a book. Could this be a SIM card issue? Hardware? Firmware? It's annoying the hell out of me, I work 10 hour shifts at night, I need my data.
Just a follow up, I downloaded a network signal info app and it shows me having a solid 40% signal. Net type: will alternate between EHRPD, EVDO A, 1xRTT, and Unknown. Data state: will alternate between "Setting up data connection" and "no activity". It seems like it's looking for a connection but won't connect. I know the signal is there. The only time I can get the 3G logo to light up is right after going out of LTE range, it'll light up 3G for a few seconds and then go out. My coworkers with Sprint have confirmed the new repeaters we have are working, and I've confirmed it won't hook up to 3G at home like my old phone.
Hi i have a nexus 5 android 6.0.1 and whenever I make or receive a call the network drops from LTE to 3G to Edge. It stays on Edge even after the call has been ended and the only way to goes back to LTE is when the phone is locked for a few minutes. I checked the settings number cellular networks -> preferred network type and its on LTE. I have done a complete wipe on the phone twice and still the same issue.
Also in the past I have another issue which was resolved and I have had this phone for about 2.5 years and after the first 6months the sim was unreadable. The person I got it fixed from stated that the guy I bought the phone off reported it stolen and the only to use it was to switch the motherboard. Im not sure if they are related .
The main issue the network dropping down to Edge is causing is when I drive for uber and passengers call me sometimes I cannot start the trip or load the gps for a few minutes .
This is because of CSFB functionality. LTE is used only for data connection and if you receive or place a CS voice call, then the phone switch to 3G or 2G (depends from signal strenght) to make a call and after that if signal is strong enough switch back to LTE.
This is driving me nuts, I'd love to know the answer. Here goes: in my room my Pixel 3 either chooses from full LTE signal or one bar of h+ (basically unusable). It seemingly chooses at random. I have gone into phone information and set to only use LTE which immediately switches me to full signal and fast internet speeds. However, when I make this switch people are unable to call me. Any idea what's going on? Why is the phone not using the full strength LTE all the time!? Why would it choose an alternative signal that I can't barley speak to anyone or use the internet! Not sure if I should blame the phone or the provider. I'd love to understand exactly what's going on
FYI I'm on Three and the phone is provisioned for VoLTE. The full signal I'm referring to must be the 800mhz.
Appreciate any advice, thanks
Pixel 3 has really bad signal. Tried to become a sms over 30min in my room. Theres enough signal for it. Not good but enough but on pixel 3 never came on.
Switched into flightmode and turned off but no sms...
I was angry cause i did mobile banking. Never had this probleme bevore. Then i switched sim to nokia8 sirocco and became my sms instantly...
Pixel3 is a nice phone in design but software is ****! Never again a pixel...
Thought on a google phone they pick the best out of a phone but it isnt
