Is this an Android feature or is there something wrong with my 3G?
What happens is that whenever I am using my browser and searching on Google and my data connection shows 3G, when I click something it switches to H. Then, after page load, it changes back to 3G.
It makes me wonder if something is wrong with my 3G, or it is some battery-optimizing done by the phone.
Am I missing something? I did not notice this with my HTC Desire, it stayed on 3G or H until connectivity became worse or better.
perfectly normal,as 3G just being the band you can be called on,but once you start browsing and download stuf,your conection turns into HSPDA(thus the H) this is the data conection integrated in 3G(its faster than actual 3G)
you can see it as a download mode.
H is just a download indicator if you ask me.
thus maybe your HTC was downloading constand or had a lower refresh rate?
the described action you present is pretty common on my nexus S
Yes this is normal behaviour in stock Android.
Great to hear, thanks
Yeah it was constant on my HTC Desire, either on H or 3G. Apps were the same, so I don't think Desire did some background work that Nexus isn't doing.
I like it, thanks!
Every phone I've had from the Nexus One would do this - usually stock roms don't show an "H," only 3G, so you can't tell that it's switching between.
My HTC desire would switch between 3g and h on Orange but if I roamed on to t mobile it would permanently show as H. I guess it can also depend on the network.

You don't want it to stay on H .. it uses heaps more battery. There's also limited capacity on the network to support H connections. If everyone connected in H they would run out. It's meant to be temporary while you need to download a webpage, etc.
Mine is doing this too

I think there's been a thread on this already, but just to reiterate:
This is just a feature of UMTS and HSPA. Using HSPA takes more battery than UMTS or EDGE, so you only want it on when you are actively downloading or uploading data. Otherwise, UMTS serves just fine for background data and syncing.
When you're reading a web page (your example), there's not a lot of data being transfered, and you're sitting on UMTS. As soon as you click a link, it switches to HSPA, pulls down the info, and switches back again.
To my knowledge, stock android shows the difference between 3G and H pretty accurately. Carrier and/or manufacturer customized ROMs often tend to lead towards leaving "H"/"H+"/"4G" in the status bar more than 3G. If you watch your "about phone" > "status" screen, you'll see your phone switches between UMTS and HSPA quite often, even if the interface is preferring to show you "H". I think its mostly a marketing tactic that also reduces customer confusion.
So bottom line, you should be happy it switches to save your battery!
I have this and trust me, it cains battery.
I have never seen H in my Nexus S.
So this is good

That's because the Nexus S is a 3G phone that doesn't have the hardware required to transmit HSPA+ signal.

The Nexus S is HSPA capable. just not HSPA+.
Actually HSPA doesn't use _more_ battery when you're camping. It only uses more battery while transferring, but even thats debatable. Eg 10mb downloaded in 1 minute over HSPA vs 5 minutes on 3G - which uses more battery to complete the task?
What does use extra battery is IF it has to switch to another tower to get you HSPA. However the network is pretty smart at choosing the most efficient thing to do, although it is biased to move people to towers which allow the most number of subscribers to be on the network. For example, if you are in a built up area and there are 3 towers within range, one perhaps right next to you, you may be switched to one further away so that one can service a user on the edge of its signal area. Although this uses more of your battery, it allows both of you to use the network rather than just 1.
Booo. So I just upgraded from a mt4g (the old one) to a GN, and now when I stream Sirius, it cuts out as it switches between H & 3G. I used Wifi today because it was driving me crazy. I wish there was a switch to turn off 4G, not 3G also.
I have the Galaxy nexus unlocked and am using it on T-mobile USA, it seems like i am getting 4G (HSPA) coverage less than when I was using my G2X. I was wondering if anyone else was feeling this way? I was also wondering if anyone has gone into the hidden menu (*#*#4636#*#*) under Phone info and experimented with changing the Preferred network type at all? I am currently set to GSM/CDMA auto (PRL) i tried changing it to WCDMA prefered, but it wont stick. I know we have done that in the past for other T-mobile 4G phones to tell the phone to always connect to 4G unless no 4G signal is present.
i too feel like its bad signal on the nexus, i changed to wcdma only though
Did yours stick? I tried to change mine, but if I go back into the hidden menu after I change it, its back to GSM/CDMA auto. My changes dont save......
i'm not noticing any difference from my nexus one really. also not noticing much better download speeds either.
mine sticks for sure
Did you do anything special? I go into the drop down menu select WCDMA preffered, then hit the back button to exit the hidden menu right? There is no save option or anything that Im missing right?
Just tried it again. I can pick WCDMA only and it will stick, but WCDMA prefered wont stick. Interesting....
are you guys getting better signal with WCDMA only or about the same?
i get really crappy 3G reception and sometimes it's so bad that i have to force my phone to stay on edge just so i can make phonecalls.
My phone constantly displays the H, but my speeds are down right despicable. Its near dial up status

I've had no problems with the GN on T-Mobile's network without changing any of the internal settings. In both New York and Arizona I've been getting 3 - 5 Mbps consistently, with peaks of up to 7 Mbps.
One thing I've noticed is that the radio switches to 3G when I'm not using data, but when I load a webpage or ask for data it switches to HSPA+. This is probably to save the battery life, so I'm not complaining.
This seems a relevant place. I just bought my GSM Nexus yesterday on Amazon and got it today. T-Mobile SIM card plugged in, I get terrible reception. I have no signal at all where I'm sitting, whereas my Vibrant and my G2 both had at worst 3G connection.
I'm not a clever man, but I know something is up. I haven't rooted or done anything to my phone. Is there something that I must do to get the phone to work properly?
To reiterate: I have done absolutely nothing but put in the SIM card.
Try a different baseband (search the GN forums for details)…
With the latest baseband (XXLA2) I seem to have better signal than I did on my nexus-s, and the nexus-s did pretty good.

Is there any update to which is the best modem to use for t mobile? Seems like one of my friends is having trouble getting signals in home but he is getting signals outside.

So I leave wifi on, and the nexus holds onto to a useless weak wifi signal sometimes before switching to 3g. Annoying #1.
When I t run off wifi, I often have 3g not activated. Often have to either reboot or toggle plane mode. Annoyance #2.
Any solutions?

Pray and wait for next official radio firmware update or burn your nexus and get iTelephone.
Move to an area with better reception. Its not the phones fault at all.

please specify which phone you have. GSM/HSPA or CDMA/LTE?
I have cdma verizon phone.
To say "move to stronger area" is not an issue. If I'm in a solid 3g are, but a weak wifi area, phone holds onto slow unusable wifi instead of solid 3g"
Have 4g off
Is there a way to have wifi only connect if over a certain strength?
Will 4.03 make 3g radio connect more reliably and quickly. Absolutely cannot use battery saving app with this phone, as when I'm using 3g, and turn phone on, either have to wait 5 mins to get mobile connection or I get the greyed out 3g

I've had the same issue. It's only happened twice where I switch off wifi and it refuses to turn on 3g, didn't think about toggling airplane mode though. I had to restart both times. I'm thinking its software, at least I hope so.

Bullschit.
This is 100% the phone's fault.
I am having this problem today. Unfortunately I have not been able to reconnect to 3G all day. 4G, fine... 3G, nothing. My two colleagues with Thunderbolts are having NO problems switching their LTE radios off and running CDMA only. My Galaxy Nexus is the only one that can't find a 3G connection.
I'm starting to hate this phone more and more every day.
If you're in an area with poor wifi, why not just turn wifi off and utilize the 3G at all times?
Same problem here. I prefer 3G to 4G for battery life. For the first week or so, no problem - now I can never get 3G, but 4G works fine. I don't think its the phone - I think its Verizon and its network choices.
Connected to wifi usually offers better battery life in my experience however weak signal kills battery so maybe keeping it on 3g is the better solution here.
Any way of you strengthening your wifi signal?

I love my gnex, but I got a microsim card adapter in the mail, so I can switch back to my bolt when I need a reliable 3G radio, until google/samsung/vzw get the radio is fixed in the gnex.
It took months before the bolt's radio problems got sorted out. I hope it won't take as long with the gnrx.

I would just turn off wifi, but when I do, it takes too long for 3g to start up...and often it doesn't start up unless switch to airplane mode

what roms are yall running?
If you're running Stock, then it's the phone's fault and you should call VZW to get it swapped out.
If not running stock, then it may be the rom at fault.
I've had this phone now for less than a month. I know it's not a long time, but I think I've got a pretty good idea of how this phone performs. I have not rooted this phone, I am on 4.02 and PRL 15119.
1. The signal problem:
Coming from a Droid2, the first thing I noticed was one or no bars where I used to have full! I was losing data all the time, until I switched to CDMA only. My phone kept switching to LTE and back again, I spent more time in hand offs than connected!
I had the opportunity to have my Nexus, a TBolt, and a Maxx all in my basement together and did a few tests. All three phones had trouble holding LTE here when I was able to run a speed test, they all performed similarly, between 1 and 2 Mbps. When all three switched to CDMA, they displayed one more bar on and off than my Nexus, but showed similar pings and speeds.
I spend a lot of time in my basement and have never had troubles losing data (CDMA only) even though it displays 0-1 bars all the time.
Now, I do occasionally have problems with data, but it's nothing new to me. My Droid2 would show full signal and just not load a page or drop to 1x in locations known to be strong service.
I have not had this problem with the WiFi hand off back to cellular data. This phone switches faster than my Droid2 ever did. Like, by a lot. I work in no service building. Every morning I turn my WiFi on and just turn it off when I get in my car to go home. Usually I have cellular service before I can even turn off the WiFi.
I read a lot of reports where someones Nexus would be outperformed in a 4G speed test by another Verizon 4G device. Not the case here. My tests were constantly the same when comparing between the Nexus, TBolt, and Maxx.
I stopped in the Verizon store and two of the sales dudes had 4G phones, a Razr and another Galaxy Nexus. The Nexus guy was rooted on 4.04 and couldn't break 10Mbps while Razer guy and myself were fighting for 40Mbps.. Maybe there are some lemons out there
All in all, I may have gotten a good device (made in China, go figure), but I do not believe there is a real problem here. If this is your first android on Verizon, I can see where you'd think there are problems. Whenever I pick up my phone, I just ignore the bars and use it. It always works. Even in 3G, this phone loads pages WAY faster than my Droid2.
2. Battery life: I am not a real heavy user. There are times when I'll spend 20 minutes in the bathroom playing angry birds or reading threads, but that's about it. I got the Verizon extended battery before leaving the store with my new phone. This battery has 200mah more juice than the extended battery in my old Droid2.
I think this phone get's great stand by time, I got it to go 3 days off charger with a few calls and texts every day and a little bit of angry birds
On a whole, I'd have to say it get's as good or better life than my last phone.
3. Random reboots: I was constantly pulling my phone out of my pocket to find that it was off. I had gotten quite concerned after reading all the posts about crash reboots. It wasn't until I set the phone down while booting it up that I saw the screen shut off. I knew something wasn't right here and reproduced the shut down by smacking the phone in my palm while it was booting it up.
After looking closely, I noticed the battery would move up and down in its compartment. I solved this by taking some folded paper and taping it to the bottom edge of the battery. Pushing the battery up into the contacts on the phone. I also added some tape/paper to the top of the battery so the cover is pushing it down into the compartment.
Obviously I can't speak for everyone, but I haven't had a single crash/reboot. Just this battery connection problem.
4. Slow screen rotation: I have noticed this, it is VERY annoying when you first get the phone. Habit is to flip it landscape BEFORE launching the app you want to use. This is why you think it's so slow, because the home screen will not flip, it just refuses to. In any app, it flips just like you're used to. A non problem that I'm sure will get fixed.
5. Screen banding: I tried looking at the blank grey screen on any brightness, I could not get the bands I kept reading about. I guess I got lucky!
6. Overheating: I read this phone will try to use 2.4 and 5GHz spectrum's while on WiFi. The first thing I did was set it to 2.4 only and have not had any issues. I use WiFi 8 hours a day every day with out the phone getting hot. I also use the hot spot almost every night, as I don't have a land line internet at home. Never an issue, once again, to the touch this phone was not as hot as my Droid2.
I really like ICS and this phone seems like a keeper. I hope this inspires someone to go out and buy the Nexus!!
Over the weekend I went to the Verizon store to compare the vz nexus signal. Turns out every device with lte read -60 and then nexus -80. But there was one lg phone that displayed both signals at the same time, 1x and lte read -60 and -80. So I wonder does Verizon lte phones actually never show lte signal and always show cdma even when connected to lte?
Just earlier today I compared my Galaxy Nexus at -110 to my dad's Rezound at -80. Side by side at the exact same time. I'm sorry I didn't take a picture.
I'm unrooted stock 4.0.2 right now.
Silly question but did the salesman with the Nexus have LTE on?
How in the world could you go 3 days on a 2100mah? The most i can get is maybe a day or day and a half. Usually its under a day as i use my phone alot.

This was achieved over a weekend in a strong service area on cdma only. I was at a solid 3/⁴ bars the whole time. I was at a buddys house for a lan, so i was doing my surfing on the computer. I was doing most of my texting in google voice on my pc, so the only use the phone saw was calls and bathroom browsing lol.
Yes, the nexus measures signal differently and this is why it cant hold 4g, it thinks the signal is too weak and lets go before it should. If you had a vzw droid before and know where the strong 3g is, set it to cdma only and see how it performs compared to the old phone. If your getting data drops and dropped calls where you didnt before, then exchange your phone.
Ive read there is a way to force lte only, this would be the best test. But i cant remember how to do it.
Want to add, the ics keyboard is the best one ive ever used. Also, speaker volume on this phone is plenty loud. I have had problems with call quality when i have no bars. Just does not sound good and hard to unserstand people. When i have a bar or more, sounds great. Like theyre in the room.

Definitely lte. I am not sure what vzws theoretical max speed is on 3g, but in our area, max is about 1.7Mbps. I know theoretical is no where near 10Mbps.

Could the differences have been due to your radios? I'm on 4.0.4 with the new radios and I don't break 10Mpbs.
The speed is fast enough for me and I don't remember exactly the speeds I had on the earlier radios. I vaguely remember breaking 10Mpbs at times. I might reflash the older radios and do speed tests.
I'm happy to report I have zero problems with my VZW GNex since day 1

Now i didnt see these guys screens, i dont know what they were using for testing or what server they were connecting to. He told me hes never been able to break 10 megs. For all i know he rooted and flashed on day one. I cant imagine the members of xda would overlook something so obvious, but who knows. Give it a try eh? For reference all my mentions have been using the official speedtest.net app and chicago servers. Im tempted to root, but im waiting for 4.05 ota and have no idea how to do it. Ill get there eventually
I've found that LTE can vary wildly in speeds. You really need multiple tests with multiple phones at the same location/time.
That said, I saw a huge difference between FC05 and FA02. I found that the best combination for my phone was FC04 on the CDMA radio and FA02 on the LTE radio. It's a good 2mbits faster and much more stable. Signal in my house is borderline, so you really see the difference.

Thanks for the suggestion.
I flash the FC04/FA02 combo and in the spot near my house where I am disappointed, 4.5Mpbs down / 2.5 up, I got pretty much the same results. One difference I did notice is that the hybrid combo is slower to switch from 3G than FC05/FC05. I toggled LTE to force 4G connect.
I flashed back. Eager to see what 4.05 brings and also if the latest official IMM76K brings new radios.

Hey guys,
I just switched from Verizon to t mobile and I have a question about their data connection.
I know they have 4g and 4g lte but are you suppose to get data while on regular 4g?
Whenever I'm on 4g I get no data even with full bar. I am currently on Jedi V5.
Thanks in advance.
Yes. Data should work at all times. Even on 4G.

lawl tmobile sucks....no but seriously, i would recheck your apn settings, make sure theyre all in order...otherwise...thats strange, i know that i have LTE all the time, but if i make a phone call, i drop to 4G because the LTE Radio has to be disabled temporarily when im making calls, which is understandable, the only other thing i can think of is T-Mobile being at fault for some kind of issue on their end. but if you can check your apn settings and try again see what you come up with.
the SAME thing happens to me. I believe it has todo where we live? Anyways in my house when I do loose LTE and get even full bars of 4G its worse then 3G. Half the times it says no connection other times it takes forever to load. I tried going in and out of airplaine mode tried turning ut off and on ect. Also tried to dial##2263## and don't work on my phone. Maybe because of the ROM? But yea my 4G is crapppp.

I also am in the middle of switching over from Verizon to T-Mobile. This is going to be a really hard decision to stay or not. In terms of Data, T-Mobile is no where near Verizon even if they have faster speeds on SOME of their towers. Verizon is very solid and I just always have Data. It isn't something you ever even think about. T-Mobile on the other hand is very hit and miss. When it is good, it is very good but when it isn't, well it isn't.
So to get to you problem, I am seeing the very same thing with my two completely stock Note 3's. I just took a trip this weekend up the cost (Los Angeles to Pismo Beach up HWY 101) so I got to see the how the network does on a trip. for MUCH of the trip, I had a very strong 4G signal but had EXTREMELY slow data speeds, It was basically unusable. Google Maps for example was completely unusable since the map wouldn't update with this extremely slow or no data connection. What I am seeing with T-Mobile is that the connection type indicator such as 4G has 0 to do with what speeds you are going to get. Many of the 4G towers I was on was only giving me download speeds in the range of 0.1 to 0.01 Mbps.
I am within an excellent range for the tower at my house, I can actually see it from my house with no interference between it and me. My speeds on what shows to be a strong 4G signal is Ping = 644 ms, Download = 0.69 Mbps and upload = 0.85 Mbps.But again, on my trip, there were many times that full bars of 4G gave me no response to anything I tried to do that required Data.
T-Mobile may have the fastest speeds when you can get them but there are WAY to many towers and that have 0 to very slow speeds on major highways! You can't even use Google Maps on US HWY 101?
I really want to stay on T-Mobile but coming from Verizon it is a huge step backwards in terms of data reliability. If I do end up staying, I really hope they start concentrating on making the data network actually usable when you are driving around. I would rather have 4 or 5 Mbps of speed on every tower vs 25+ Mbps on some towers sprinkled around that your lucky if you live next to one.
