Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.

Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.
Cheers,

i have sprint as well and when someone calls you when youre running hybrid, you should not miss calls. you will get disconnected from the internet when someone is calling though

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!
You actually use mms?
Wow, they do exist.

What NOM1 Networks are there in the UK? I only get 2g in my area (booo) and could do with an operator that works right. T-Mobile forums suggest they still have an issue
Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?
Ok, first off my Vibrant has flat out awful reception.. fluctuates randomly between 4 bars and 0 bars on 3g and sometimes cant get more than 1 bar 3g in the middle of an HSPA+ city(Memphis). Its not a bar display problem, sometimes my speedtest shows download speeds as low as 150kbps. If that wasnt bad enough it takes forever to switch between 3g and edge, by forever I mean sometimes a full 60 seconds+ and if Im running a data using program (Pandora for instance) it sometimes refuses to switch at all... Is this a known issue or is it just my phone?? I know my G1 did not have these issues.
Try doing a master reset on your device.
If the master reset dosen't work, you might reflash the full stock rom from the android dev section. There's alot of people that have been reporting substantial increases in their reception and connection speeds.
And if you think it takes a long time to switch b/t 3g and edge, you ought to try owning an evo for a month. It takes FOREVA to switch the 4g radio on and off, at least 3 min for me, takes about that long to turn it on after a reset too.
Just because you're in a HSPA+ city doesn't mean you're on the HSPA+ network.
If you're having problems with it aquiring the 3G network try a new sim.
The G1 has mediocre reception but it is aided by the fact that the antenna is at the top and not the bottom like all other phones.
Bump,
I am actually having this problem too, I have tried a factory reset, I also tried reflashing the T-Mobile stock fimware, but it has not helped. I have good 3g and edge reception where I live.
Oh yeah, I am using ATT on the vibrant.
When this happens (ie. not switching between network or slow switch time), you can trigger airplane mode and then undo it and the phone will pick up the right network or switch network faster. For example, if use 2g network is checked, it will enter Edge, etc.
I see exactly what you guys are talking about, locking it on 3G will fix this right up. I was driving down the freeway and I KNOW I was passing 3G towers, but the Vibrant stayed on EDGE for way too long. I locked it on 3G and I never lost the signal and it was 4 bars for nearly all of the trip so I know 3G was there, it just wasn't switching back fast enough.
Looking under the Samsung debug mode, the Vibrant will hold onto 3G until -115 Recieve power, which is basically -115dBm under the Android network menu. Of course over -101 RSCP, it will show 0 bars so it's hard to know when reception is acutally really bad.
It should show -0 bars at -113dBm, 1 bar until -101dBm, 2 bars until -89dBm, 3 bars until -79dBm, and 4 bars until -51dBm.
just disable the extra frequencies from service menu and it will be super quick.
I'll try that, at any rate it should be remedied by Samsung.

That's an unintuitive user interface. sheesh.
Looking at Wikipedia, it looks like TMO uses 1700/2100 WCDMA and 850/1900 GSM (2G/EDGE). There's also a WCDMA 1900, but according to what I'm reading, TMO doesn't use WCDMA signaling on 1900, just GSM/EDGE.
To try it, go to the service menu using the steps for 3G locking and select 1700 only instead of WCDMA ALL. Then go back using menu/back (not the back button) twice and go to Combi Bands and select WCDMA 2100. That should enable just 1700/2100 WCDMA 3G service. Turning on PCS 1900 does seem to get me an EDGE connection. Enabling GSM 850 ONLY gives me emergency calls only, so it might be worth keeping on for 911 calls. 850 goes further so it might have service when the others don't.
I don't get 3G service in my basement, for example, so I would like to keep EDGE enabled. Hopefully enabling just the bands that I would use will help keep the search times down.

To really get a full re-flash, you need Odin right now. It should be possible to do it without Odin now, but I don't know if anyone has put together a stock ROM that way yet.
I didn't see any difference in speed/stability with the stock Odin flash, but others might have. It seems to depend on the network more than the local stuff.
Band IV 1700 includes 2100Mhz so you don't have to enable it. From what I can tell, no.. combi-bands doesn't do much for the slow 3G requisition. I'm just going to lock it on 3G when I'm not at home.

This didn't work for me. I would do this, and it would only work changing from 3G to EDGE. But, from when I would put it on use 3g, it would first change from airplane mode to EDGE, then take around 1 min to change to 3G.

HI all!
Right now I am using [Build][10.12.2010][NexusHD2-FRG83D V1.8 PPP+RMNET][Kernel: hastarin r8.5.3_oldcam] and that is quite ok for me.
However I havent found anywhere on that build an option to disable HDSPA speed.
What I would like is accept 3G but disable HSPDA. Now I only have a change to disable 3G totally and only get 2G. Basicly area where I live is keeping me a situation that phone is very often trying to connect HSPDA but then changes is 3G speed. It causes me time&battery drain.
I have found a solution to force phone only use 3G but that is what I wanted. 2G and 3G are ok but I want to disable HSPDA.
Anybody could help me?
Up, Up... anybody have same kind of need?
i also need same help regarding this, reason is my data plan only use 3g (umts) and not 3.5g (hsdpa)... but my android always switch 3g to hsdpa back and forth and drain battery much faster
is there any tweak/program/widget/application that can enable 3g (umts) only?
windows doenst have this problem cause in winmo i can switch the option easily (enable/disable hspa)... but android dont have this kind of thing
I have the same problem. I don't even have HSPDA where I live, yet it tries to connect, fails, and then connects to 3G. It's a very time consuming processor to wait for the phone to do this when I am just trying to load a website.
Yes.. maybe it will not drain much memory but.. who wouldn't want a fast internet..
Afaik Hsdpa uses the same radio towers (or whatever the name is) as Umts... just different software. so there should be no battery drain caused by this.
This mite help you
1. Go to your dialer
2. Dial *#*#INFO#*#*
3. Click 'Phone information'
4. Scroll down to the first dropdown selection and set according to your preference below...
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

uhh... maybe you dont catch what us mean....
when umts change to hspda (icon change from 3g to H) then it use battery power.. in my case i use 3g (umts and not 3.5g or hspda )data plan only... but android keep searching hspda signal and THIS is when battery used the most (the process) and EVEN when my area have 3.5g covered but because i use 3g only data plan... then the back and forth process (3g<->H) will kep coming and rdrain my battery fast
so... we look for any kind of workaround so our android keep stay in 3g (umts) and not drain any unnecessary battery power searching for hspda
btw sorry for my english

i use this thing before and no luck
i use "wcdma only" as the option and android still process 3g and 3.5 back and forth, maybe android "thinks" 3g/umts and 3.5/hspda as the same?? android categorize umts and hspda as one big fat 3G network
i wonder why newer os like android doesnt have this kind of feature in winmo there is an option :
disable hspa = so hspda disabled.. AKA 2G or UMTS only
enable hspa = enabled hspda, hspa, hsupa etc.. AKA 2G, UMTS and HSPDA
try this settings
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.

isnt cdma auto (prl) used exclusively for cdma phones? (those phones with evdo and wimax thing) and not used for our hd2 (GSM)???
C'mon how this is impossible with newer phone software??
This feature has been in WinMo and Symbian in many years!!
It is really frustrating that almost every time my phone is trying to make HSPDA connect and then decide 3G is enough and possible. It causes some delay and sometimes also timed out errors.
agreed
my android keep going back and forth between umts 3G and hspda 3.5G like some clueless kid while 2 experienced guy (symbian & winmo) laugh at him
i know this is a old topic
i have still this issue
my phone is switching to hsdpa an back to 3g after a few seconds
when the phone is connected to my slow wifi connection everything works fine and i can use it for 3 day's
when it is connected to hsdpa my battery is empty after 15 hours and the voip connection is not working properly (i need to start a ping to some server first to keep the connection alive so i can call with voip)
I just came upon this thread, but I don't have this problem, so I can't really test it out this theory. But my thought was, what if you just went into the build.prop file and edited the ro.ril.hsxpa.category settting from ro.ril.hsxpa.category=2 to ro.ril.hsxpa.category=0. I just tested it out and it never jumped from 3g to H. My only concern is that you wouln't get the fastest speed you could be getting. Test it out and let me know though.
at this moment it is not posible to root my phone (SE Xperia pro with latest firmware)
so i am afraid we need to wait to test this
but thanks for the hint
No matter what I do my phone will not switch to edge. I tried enabling the 3g toggle and when i turn it off it stays on 3g. My signal would drop down all the way to no signal and not even go into edge. Anyone else having the same problem? This is my third focus so far and the previous one had the same thing.
I have a captivate and a focus, and both pick up 2g edge. Of course, where I live, I do not have 3g coverage. However, when I go to work, I have 3g coverage. On my captivate, to pick up 2g edge service at work, I have to manually disable the 3g wcdma bands on my device. Of course, I would prefer to connect to 3g over edge anytime, so I haven't tested with the focus. I am not even sure if I can manually pick what bands to connect on with the focus. On the captivate, I go to the phone dialer, and dial *#0011# to see what band I am connected on, and dial *#2263# to select which bands to connect to. If you are looking for the best speed and signal possible, you should try to connect on wcdma 850mhz band if your phone will allow you to choose. I will do some testing on my focus and see what I can come up with.
Sent from my SAMSUNG-SGH-I897 using XDA App
I just received my second focus, due to it getting run over, and this new Focus has the same problem as the op. It will go into 2g but first it goes to no bars on 3g, which means I lose the call. This is at my home so it's really aggravating, it loses signal every time. It will go from 3 bars on 3g to nothing.
I don't understand how this phone sucks yet my last Focus didn't do this. I need to ask for a replacement again. I'm not sure it matters though because the op is on his third phone. I guess I should have switched carriers as I had the same damn problem with my Fuze.
Using N9005, I've noticed that I get stuck in 2G after making/receiving calls. On very rare occasions, I'll be on 3G after the call, but usually I just get stuck on 2G for long periods after that, unless I go into Network Settings and toggle it to WCDMA to force it out of 2G, then toggle back to LTE/WCDMA/GSM.
Alternatively, does anyone have any way to completely disable 2G?

Yeah 4G does not work on call it will go to h+ or 3g or g it should take about a minute to back to 4g or whatever it was on, all phones do this

Yes, I know, just that it seems to be very rare that my phone is on 3.5G or 3G after ending a call.
Taking a closer look at the 3G reception in my office (pretty much the only place I make/receive calls), I realize that the spottiness of the 3G reception could be making my phone choose 2G over 3G. Guess I have to test this out somewhere with better reception.
