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.

I'm pretty sure hes talking about only having it on 1900/1700 (combi bands)

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.

I was wondering is there a way to force 3g signal while on a call???

The phone should automatically go to 3g is there is 3g coverage. I do not know of any way to force it. You can go into the phone settings and make it use WCDMA/UMTS only. this would however make your call drop if you go outside of 3g coverage.

oh i see...but is there away to pick up 3g if it drops to E and im in a 3g area while on a call
I doubt that there its much that can be done during a call. Mine sometimes drops to EDGE when I am on a call too. It picks the 3g signal right back up when the call ends though...and it doesn't happen often anyways.
I noticed when i am on a phone call, the E or H(aka data tmobile data) turns off while i am in the call and disappears. Then comes back after i end the call. Does anyone else notice this or know how to make it so it stays on even during a call? Also, when wifi is connected the data service turns off?
First off this is normal when your in a 3bars or less 3G/H area. Your phone will switch 2G while on a call if the 3G signal gets low but it won't switch back until the call is ended. Also on 2G/E you can only do one at time, voice or data. T-Mobile's 2G network is stronger than their current 3G network also.
So if your on a call and the H disappears, this means your phone has switch to 2G/E because your 3G/H signal was low. You won't see E on a call since that would be data and 2G can only do one at a time.
If you want to force 3G/H then goto settings, wireless and networks, mobile networks(I believe) and select WCDMA only under network mode. Please note that if you go into a non 3G/H area you will loose complete signal and your phone won't switch to 2g.
and yes wifi disables mobile data.
Good luck.

Okay that makes sense because i only get edge/2g service in my house. Thanks for the response!
So when I got my Mytouch 4g I realized the default radio is set to GSM only, however with my stock Nexus One it is set to WCDMA preferred.
I've been using my MT4G for about a month now, two weeks with it on GSM Only and another two weeks with it on WCDMA preferred.
I've noticed that while on GSM only it tends to prefer edge instead of 3g or HSDPA+ and find it very annoying because it does it in places where I know i hit HSDPA+.
When I set it to WCDMA preferred i've noticed that it sticks to 3g/hsdpa+ a lot more often and it's stable, except for in the market. A lot of the times when i go into the market while in wcdma preferred it times out and tells me theres no connection or something like that.
Can anyone tell me which network type is best for this phone? Or maybe explain them a little bit? I just find it odd that my Nexus One and my Mytouch 4g have different defaults if they're both on the same carrier
its prob just the setting it was on when the phone was out the box. when i got mine, it was set on auto. "gsm only" will NOT allow you to connect to 3G or hsdpa+! gsm is edge and gprs! if you want it to chose between the two then AUTO is the way to go. it will prob pick wcdma first and then only jump down to gsm when the wcdma signal is weak or non-existent. i prefer mine on wcdma all the time too. i havent had any issues with the market as of yet. you might want to try to clear the data and cache in market and see if that helps. when mine is on auto it 99% of the time stays on wcdma until the signal gets weak and then auto switches to gsm/edge. the only reason i dont keep mine on auto is because when its on auto and i receive a phone call, i dont get data(the H or E disappears while on call, then pick back up when i end the call) and i need to have data going in and out while on the phone to get emails from school and my job so therefore i leave it on wcdma only
Thats pretty much correct. GSM only means 2g only. Wcdma only means 3g only. So if you dont have a 3g sig. You have no sig. Wcdma prefered/auto means that it will stay on 3g untill the signal becomes low and switches to 2g. When it finds a good 3g signal again it will switch back to 3g.
If you hav it on auto, when your on a call it stays on 3g until it gets low then switches to 2g to keep the call alive. But it does NOT switch back to 3G untill you hang up.
I usually keep mine on wcdma only because i have good 3g where i live and i hate when it switches to 2g during a call because i personally can notice a sound quality difference and i alao like to be able to use internet in call if i need it
