I had been having problems getting 4G at home and just noticed that if I turn off WiFi, 4G pops right up and as soon as I re-enable WiFi (which connects to my home network) 4G disconnects. Has anyone seen this behavior? When you think about it, it makes perfect sense, and since both are enabled to connect when the other one isn't, the flip-flop is automatic. But it surprised me.
its probably because sprints 4G is based on WIFI. or it just cuts off 4G cus you dont need it anymore
I believe it works the same way as WiFi and EVDO works on older phones. When you turn on WiFi it will use that as your data connection instead of EVDO regardless if it is a crappy WiFi connection.

Yeah, it's actually pretty cool, but if you don't know about it, it gets frustrating. I called Sprint customer service and he had me go through the battery out/in routine and go outside and try, etc. So maybe they don't know about it either!
But it makes sense for Sprint, since their data plan is unlimited and they want to avoid network overloading (are you listening AT&T? LOL). The only thing you miss on WiFi are location-based sevices that rely on GPS (navigation, some weather products, etc.).

WiFi and 802.16e aren't all that similar. LOTS of differences between the protocols.
Maybe there's some isolation problems on your device as Sprint is using their 2.5 GHz spectrum holdings for their 4G network.
4g network and 3g network both will shut off when enabling wifi. Why have 2 forms of data going at the same time? Its not gunna use both to double your speeds.
You wont lose any GPS features. Turn on wifi and load up Google Maps, it will find your location exact.
When making calls and sending text it uses 1x so you will still receive everything except for MMS. Maybe they fixed it to where you can receive them even when on wifi with the Evo, not 100% sure.
4g and WiFi are both data only connections. You don't need two data connections simultaneously so it is smart enough to auto disable one to save battery. It would also cause routing problems.
Every phone does this LOL When you switch on Wifi they turn off 2g,3g,4g etc because you can't use 2 data connections at the same time.
I'm curious why you would want 4g and wifi on at the same time?
I thought this was pretty common knowledge (on any Android phone)... And I also thought it was done for battery conservation reasons as much as anything else. WiFi's a simpler point to point connection and from what I understand it sucks less power than 3G or 4G which is constantly checking for additional cell towers in case you've moved, etc.
If you're at home or at work w/a stable WiFi connection you should be able to preserve more battery power by using it, within the settings you can even set it so the phone doesn't revert to 3G when it goes to sleep (the default setting IIRC), otherwise it does this and only jumps back to WiFi when you wake it ('till you're out of range anyway).
I agree with all the comments. And if the Sprint Customer Service guys had said, "Hey, you idiot...it's supposed to do that," then I wouldn't have posted. But the fact that he was as stumped as I was prompted me to post (we all know that Sprint gets all it's info from reading these forums...LOL).

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.

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.

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!

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?
At my work I get 0-1 bars of Sprint service, and my phone often roams onto Verizon (we have dozens of Verizon repeaters in our building). The problem is that quite frequently lately it will get stuck in roaming mode and never switch back to a Sprint tower. I have 6 bars of Sprint service at home, but it will remain in roaming mode. I have the newest PRL (60670), and the old PRI (1.34_003).
Anyone else ever experience this? Any idea what I can do to fix it?
I have had this happen in the past as well. What I did was go into settings and change the roaming option to "Sprint Only" which forces the phone to switch back to the Sprint network. Then you can change the roaming option back to "Automatic".
I get this a lot as well. I've started to make a habit of turning on airplane mode, then turning it back off... when it scans for signal it will go back to Sprint.
Sorry if i'm stealing this thread. Is it pretty bad if my phone has to go in roaming to get signal in most my house? I've seen the threads about people getting a airwave because they get dropped calls, but since i have to roam in more than half my house, does it seem possible i could get one from sprint?
And my house is in the middle of town, if you go outside there's 4g, but not inside.

Same here, I just toggle airplane mode on and off.
Same thing on my EVO. It'll roam when it should but it won't switch back to Sprint when it should.
I chatted with Sprint asking why this happens. They just said I have free roaming. No reason why.
Yep, My Evo has been doing this as well. Been doing the airplane toggle trick. Thought about just leaving it, but was thinking that it may burn my battery faster? Anyone have any thoughts on that..
My PRL is also 60670, but I have the 1.71_003 PRI.
Guys if you have any type of active data connection the phone will not drop the roaming.
I roam at work too and if i turn on Aonline radio, tjen get in my car and drive, so long as the radio streaming is going iy will never drop the roaming.

Messed with the phone again tonight. Got stuck roaming again. I was not transmitting anything, and even ATK'd everything to make sure. Who knows, not really a big deal, unless I am eating more battery.

That makes perfect sense. I sync with my Exchange server at work and the way EAS works is a constant connection between the client and server. One question though. Has your phone switched back to your carrier with no data connection?
Yeah just disable always-on data or cycle airplane mode to make it switch back. As long ad its maintaining a data connection it will wait to switch back from roaming so it doesn't unnecessarily disturb your connection if you're in a poor service area. It shouldn't be using any more battery.
Also, atk is bad.
Sorry if this is common knowledge and I'm just sllloooowww....but I have discovered something with my EVO that was driving me nuts!
When you connect to a WiFi network the phone will automatically drop your other data connections (3G or 4G). If you are connected to WiFi and turn on 4G the phone will not connect to 4G and instead will show a status similar to this:
turning on->scanning->disconnected
or
turning on->scanning->connecting to spring ->getting IP address -> connected ->disconnected
All of this was quite irritating when I was assuming that my 4G wasn't working properly. It was pretty embarrassing to learn (through many trials and errors) that I hadn't correctly associated the 4G connection 'issues' with the presence of a WiFi connection.
Hopefully some of you who are experiencing 4G 'issues' are just suffering from this same ignorance.
P.S Please don't take this as an opportunity to rip on myself or others for being ignorant, thank you.
Thank you for taking the time to right this up. I would have thought this to be common knowledge, but I can see how the cycling of 4g connect disconnect could be confusing.
It will always drop the current connection if you switch it, doesn't matter which carrier you're on. reason you can't connect to 4g (aka WiMax) while on wifi is because they are using the same frequency 802.11. the only difference is that wimax is on 802.11E where as the wifi on the evo can go 802.11B,G,N

Wimax uses the 802.16 protocol which is seperate completely from wifi.

I'm not sure why they are disabled when wifi is on but my guess is to conserve battery or avoid confusion with data connectivity such as flipping back and forth between radios. Who knows why heh

Heh, well once I realized what it was doing it became pretty obvious why they were doing it.
There's no need to keep more than one data connection up on the phone, and obviously the less data that flows over sprint's (or any carrier) airwaves the better for them. When WiFi is connected, it makes sense for the phone to shut down the cellular data to reduce network load. Also, I am not positive about 3G vs. WiFi but I am pretty sure WiFi uses considerably less power than WiMax, so it makes sense from a battery conservation perspective too.
This is actually a common practice on smart phones it seems. I confirmed with my brother that this same thing happens on his Moto Droid with Verizon (when WiFi connects, 3G disconnects).

It has more to do with conserving battery life than taking a load off of Sprint's network. BTW, WiFi tends to use a lot less battery than 3G.

I love my new Galaxy S III, but once again I have no way to force HSPA+ only. I need this option while my phone sits in my desk all day. If I can turn LTE off then I can save battery life and still get calls/texts/emails.
STOP IT AT&T, JUST STOP IT!!! Your really starting to really aggravate your customers by not allowing them to select their preferred network.
I want the network mode option in mobile networks:
GSM/HSPA/LTE (Auto)
GSM/HSPA (Auto)
HSPA (only)

STOP taking this off all your phones. Every other GSM carrier in the world allows this except you!!!
I hope ALL developers add this toggle in all the upcoming roms.
Your best bet until this is added/fixed, is to turn on wi-fi mode and turn off the mobile data connection.
That way you still can make calls, and have the wifi as your data, and if its off it wont use as much power as HSPA/LTE.

I think you kind of missed the point...
Let's say your at work all day and you don't use your phone much? Let's say your phone gets 1 bar of LTE and 4 of HSPA+. The signal constantly fluctuates ultimately leading to a dead battery much faster.
Wouldn't it be great to just turn LTE off? That way my phone gets a better signal and uses less battery life. Not to mention, I can still receive calls, texts, and e-mails, whereas airplane mode disables everything.
Wi-Fi isn't available everywhere.
PS: AT&T ain't adding ****, they released their first LTE device in November of 2011 and it also lacked this option.
I think you missed the point as well
The reason for turning on wi-fi is to direct the data connection to something other than the chip used for HSPA/LTE. I'm not looking to use the wi-fi connection as an alternative data source. I'm using it to prevent as much battery drain as possible whenever I am not using the phone.
It essentially IS turning off LTE, but it also is turning off your data, and if you don't have wi-fi then you wont have a data connection, but if you do then you will.
Airplane mode is just taking it a step further and blocking calls as well.
So there's no way to turn off LTE? Even via a 4g/3g toggle from the app store?

Then it would be best to turn off the Wi-fi and the Mobile Data connection, the only reason I have the Wi-fi on is if I'm in an area that has it (home, work, at&t hotspot) otherwise it is automatically turned off (I think?).
And I agree completely, I would love that feature, but until that time we have to make due with what we have, this is my solution, it isn't perfect but it works for me.

Yes, but like I said turning off mobile data completely turns off the data connection, whereas with this toggle we can change it to EDGE or HSPA+ only, still having a data connection.
I agree I like turning on edge only when I'm at work and home

I believe it just turns off 3g and 4g on verizon. My calls and texts are instant. Also, if you buy the app you can change frequency. Mine syncs every hour or two. It may be different with att since verizon handles their 4g in kind of a silly way.

It acts like it cant switch between 4G and 3G. sometimes it might take 5 min or more before it will reconnect to data. the phone works fine when it is in a strong signal area. So far I have just experienced this behavior in low signal coverage.
Yesss! Experienced that yesterday. But came back on in 5 min. Usually fixed when u go to settings and switch from the lte to GSM and back to lte but haven't had trouble with it today

Yours is the first case I've seen where data drops altogether, most have just been going back to 3G too often.

I am having the no data issue as well! I leave my house (on wifi and supposedly 3G or 4G) and I want to start listening to music immediately in my car but I have no data connection once wifi is off. It can take over a minute or more to get a data connection! I was wondering if this had to do with LTE protocol negotiation, as this is my first 4G phone. However it seems way too slow and its very aggravating. When it does get data back, it is usually 4G not 3G. Toggling data mode on and off doesn't fix it. I have not yet tried toggling between CDMA and GSM.

does it only happen when you're leaving wifi and going to cell data?
My experience with data connection was spotty for the first couple days. Going from WiFi into 4G then 3G on the way to work required a reboot to pick up the 3G after I arrived.
I think I may have found my issue.
Settings -> More... -> Mobile Networks -> Network Mode
Was originally set to "Global". I've found that "LTE/CDMA" works better for me.
hope this helps some.
