Even though this is my first post, I read this forum several times weekly, and I have not seen the following discussed.
If you download the "Mobile Signal Widget" from the Market, it will show you when you are getting a 3G or 4G connection. It shows "H" when the 4G signal is active, and shows "3G" otherwise. The on-board signal meter does not. It just shows "H" for both 3G or 4G data.
If things work with your phone like they do with my phone, you will see that when no data is being sent or received, the widget always shows a 3G signal, even when in a strong 4G area, and never shows a 4G signal. If you are in a 4G area, the 4G signal shows in the signal widget only while data is being sent or received.
Please try the following test with the speed test app. Before running the speed test app, and if no other process of the phone is sending or receiving data, the signal widget will, as noted above, show a 3G signal. If you run the speed test app, and immediately after starting the actual speed test, while it is still sending and receiving data, you return to your home screen where the signal widget is placed (NOT by hitting the back key, which closes the speed test widget and stops the downloading process, but by hitting the home key, which allows the speed test widget to run in the background while you view the signal widget on your home screen), you will notice that the widget will show a 4G signal while the speed test app is processing.
However, when the speed test is finished, the signal widget will go back to showing a 3G signal within a few seconds of the speed test finishing its processing. You can see this by viewing the up and down arrows activated in the on-board signal app shown in the notification area. When data is being sent or received, the arrows show, but when the data is no longer being sent or received, the arrows disappear.
The same applies to other apps sending or receiving data.
I'm on my third phone, and this 3G/4G switching has always happened with all three phones I have had in my possession. Thus you can see that in a 4G area, when data being sent or received starts and stops, the phone switches back and forth between 3G and 4G all day long.
Since this has been the case with all three MyTouch 4G phones I have had, I have to conclude that this is the normal and expected circumstance as designed into the phone and the 3G/4G broadcasting system.
This may have something to do with the somewhat bad battery life, plus this has other possible ramifications. I'd like to hear what some of you think about this 3G/4G switching, and the possible ramifications.
Yes it is 100% normal...that's common knowledge around these parts...No need to be using 4G when not sending or receiving data.
from the way it's been explained around here hspa is a protocol for 3g that doesn't kick in until data is sent or received, there isn't any actual switching going on unless you're moving from edge to 3g. T-Mo was smart in only using an H on the stock ROM, imagine the questions and complaints coming from inexperienced users seeing their phone "dropping" H all the time. The phone has to be able to handle the protocol, so obviously the devs have taken advantage and included the capability of showing when the hspa kicks in, but really it's just an added touch. As long as I'm getting solid consistent speeds you can put a piece of bacon as my data icon for all i care. At least then I have a constant reminder of the most important food group.

Is that how the stock ROM works? (it's been 6 months, so I can't recall) On the two custom ROMs I've run, if you're in a 4G/HSPA+ area the built-in data icon will show "3G" when no data is being used and switch to "H" when data is actively being sent or received.
Yes, the stock signal widget does not differentiate between 3G and 4G. Both are shown as "H".
I have mobile signal widget and when my phone signal shows H my signal widget does too, when in 3G the widget shows 3G, when in E it shows E on my widget and so on.
So H being for both 4G and 3G is not always true.
I'll try to post screenies when it show other than H.
Are you on the unrooted stock ROM?
Sent from my HTC Vision using XDA App
H means High Speed which is anything beyond the first 3G spec like UMTS/HSDPA/HSPA+. When preferred network type is available in the area its used for default RX/TX. This is done to save battery as if you were to connect on 4G based service you would eat alot of battery compared to 3G. Based on stock or AOSP based rom you also will get more accurate reading as we know how stock always emulate more than there is in the area. so OP its normal behavior.
As you can you see from my screenies, my phones signal reflects on my signal widget the same.
I'm on royal panache with latest radio.

Well, that's why your case doesn't count. The OP was clearly talking about the STOCK ROM, which isn't your case. Most or all stock ROMs don't differentiate between UMTS and HSDPA and show a single indication for both, for a good reason - because most people don't know how it works, and showing them will only cause questions/complaints/confusion. This thread might be a good example, why.

When you're right, you're right. He indeed doesn't state it. I guess that knowing the difference in behavior between stock and custom ROMs, I automatically assumed he did.
Never knew this thanks
My wife just upgraded from the MyTouch Slide 3G to the Slide 4G. The 4G is constantly dropping to 2G so obviously the data speeds are terrible. Her Slide 3G usually always stayed in 3G in the same areas the 4G is now dropping. Anyone else experiencing this?
Did experience something like this at a friend's house.
Sounds like the problem that the one of the reviewers of the Sidekick 4G was having (ping-ponging between 4G and 2G). Not everyone was having that problem in the wild, though. Could be a coincidence that two recent physical keyboard-based 4G phones are having trouble holding their T-Mobile HSPA+ connections and skipping the 3G alternative, though it could be a bug with T-Mobile's HSPA+ at the tower or phone level. I don't know know the protocol rules on the handoff between 3G and HSPA+. Some reviewers have reported lower data rates than expected with the Slide. The Sensation supposedly has a death grip issue, so maybe there's a variation of that with the Slide (due to a different landscape hand position using the physical keyboard) resulting in 2G connections. Could be temporary capacity issues with your wife's local 3G/4G towers. Is this a constant problem or worse at different times of the day? I remember a few years back reading a report on 3G mobile streaming usage experiments in Europe that it only took like 8 people streaming on the same tower to saturate the tower's 3G capacity. Of course, the number should be higher with HSPA+, but just wanted to point out it is possible for a tower to get overloaded. Keep us posted. This is the kind of stuff that will determine whether I get the Slide and stay with T-Mobile.
I'm in MD and I'm constantly having this issue in my apartment. One minute I have 4g and the next I have 2g and it wont switch back until I restart the phone. I wont even be holding it and i see the issue. Dunno, at least I have 14 days to bring it back.
Had same issue with my sensation. Try going into settings and switching to just wcdma as opposed to it picking between gsm/wcdma. It is under wireless and mobile settings. That is assuming you are in a good 4g area. It will not show 3g

Well i saw this happening on the 1st floor of my house. But it was in a hallway away from the windows. but when i moved it came back to 4g and stays there. I think it has do more with the tower and whats available in your area.
Should I ever see 3G on the phone? Currently it is only ever in 4G or 2G. I notice the manual mentions 3G also though. I was assuming it always said 4G even if it was really 3G, but now I'm not sure. Has anyone seen 3G at all for their signal? I'm wondering if there is a setting wrong on the phone.
For those of you that don't have the network settings, go to the market and download an app called Network, it's free. Scroll down to set preferred network type and chose WCDMA only.

This issue is the phone itself. This is a verry buggy phone. Coming from a family g1 plan and were very excited but these phones have issues. Cant wait for root. Neways i know the 2g issue is that it gets stuck and u have to reboot. For ex. I tested in cordelane ID in near costco. Full 4g bars. Had 2 mt4gs's. One phone was in 4g and the other was stuck. I tried the old g1 trick they had in the beginning switching in and out of airplane mode. Did not work. Rebooted and it worked fine. Many other issues like all the time on both phones the widgets get stuck. U must slide to next screen than go back and widget works. Like i said i have 2 phones so i can troubleshoot and feel confident its not a glitch with a particular phone, etc. These phones suck.
Really annoying when it switches from H+ to 3G and vice versa since it loses connection whenever it does.

So what do you want to happen instead? I'm not sure why its annoying, it's something that the phone should do since its an indication of what network you're on. Whether your stock or rooted that would happen. I guess you can just open up the ROM you're using and just turn the 3G symbol into the H symbol or turn the H symbol into the 3G symbol. I'm not sure if that's gonna work though but worth a shot.

It is annoying to some people because they are in an area where they are picking up two different towers and it is switching between towers, which means dropped calls. This is usually a problem if you are in a marginal area. This is what would be happening to me at home if I didn't have my microcell. The ideal fix for this, without the microcell, would be to be able to lock on to the the tower that is providing the 3G signal.

What (s)he said. Also disconnects and stops videos I'm streaming, forcing me to begin at the beginning. Would prefer to just stick with the more widely available 3G.

You just really like to poke holes or come at me don't you? Annoying, okay fine. I see how that can be annoying for those in marginals areas, to each their own. I'm more of a function over form type of guy and when it comes down to it, I'd rather just deal with the switching to know what network I'm on rather then changing icons or disabling it from showing the change in networks. Again to each their own which is why I offered my help. You're right, locking on to only the cell tower with 3G would be ideal but without said microcell, I think the OP is SOL for now.
Again, to the OP and to answer his questions, I don't know of anyway to prevent the change. I don't know of anyway to keep just 3G on or turn off 4G so it doesn't change so much. Like I said, I think the work around here would be to just change icons so that even if it does switch you'll only see one icon and thus eliminating the change in the status bar. If that works, you can always check the network in the about phone section.
by default it will latch onto 4g even if its a weaker (but usable signal) im trying to find the build.prop setting that will make it pick the stronger signal over speed. i remember seeing that before.
i believe
ro.ril.hsxpa=2 should put it to 3g. i have no signal where i work so i cant test. backup, change it, reboot and see.

I'll give this a whirl, completely forgot about the build.prop..since being on Abso I haven't had to mess with it in a while, I'll give this a whirl and let the OP know. Thanks Dar!
edit: just tried it, still sticking on H for me, but I believe it may be because of where I am located. I get 4G speeds/signal so it rarely needs to bounce to 3G, hope the OP can test this out.
as a super noob i was playing around in there not knowing what i was doing, and completely made it lock me to 3g/2g mode and i was rather upset lol.
thanks bacon!

Just giving info bro, especially since I have first hand experience with this. It was a problem for me even when it was switching between 3G and Edge, which is what prompted me to get the microcell. Not everyone's situation will be the same as yours. If you feel like that is poking holes, then so be it, but the holes already exist because of this. No poking needed. The icons displayed are really meaningless in comparison to the actual signal. If you were experiencing the constant drop calls, I feel you would think differently. The phone is switching due to the cellular signal, the data just switches along with. It would be more useful if the op could lock to a specific tower. This is why the microcell works. It is the strongest cell signal near the phone, so the phone stays locked to it as long as you are in the proper range.

im goin a lil offtopic, but i need more feedback to continue helping. anyways, how do you like the microcell? i been contemplating getting one where as if i sit down in my apartment i lose my calls and some rooms i get nothing. its annoying.
@ Darunion....I have had my microcell for a year and a half now and, while it has not worked flawless, it has worked good enough to be able to get rid of my home phone. I still get an occasional dropped call, but at least the cell phones in my home have been usable since getting it. I do recommend it in those really tough situations where there is lack of even a decent signal in one's area.

Oh having it swap between signals will be a huge battery drain as it is always bouncing back and forth. There is an Something somewhere that should be able to stop it from trying to connect to the 3.5g network. ATT has no 4g. A seach will tell you what you want to know.
OK, so as I'm sure some of you are seeing, there's an issue with the HSPA/UMTS switching. Like a LOT. I've tried to do Speed Tests, but simply am not able to, because the connection wants to switch from 3g to 4g and back over and over again.
I wanna see how many of you are aware of this and are fed up with it. It's kind of silly. C'mon HTC.
I too have noticed this issue. I'm sure it will be fixed quickly. Such is the penalty to being an early adapter.
Doesn't affect my calling in no way whatsoever. Does mess with my browsing a bit, and after connecting to my home wifi i can say that the switching is definitely the cause.
Hope it gets a quick and tidy fix soon.
yep I see it all the time, doesnt bother me though
I think this is a bug in all HOS

The Galaxy Nexus does this. It switches between 3G and H based on what is being done. If you're not browsing it is on 3G, and if you're browsing and actively using the connection it switches to H. My One S doesn't do this at all unless I'm in a fringe area.
Agreed with the OP, this is annoying, because while the device is in this period of switching there is no data transfer possible, it can stay like this for a long time, sya a few minutes not just a few seconds.

No, it's nothing like that at all. I came from a Nexus S, which had HSPA (not +), and it would switch from 3g to H, and it was never a problem. The issue here is that once it gets to H, it suddenly dies out, switches back to 3g, goes for a sec, dies, switches to 4g, and over and over again. It's nothing like what you're describing, because I'm very familiar with your situation.
In your situation, as you described, it switches based on usage. So, if you're using data a bunch, it'll switch to HSPA+ and stay there until activity dies down. On the One S, it switches back right in the middle of doing data-intensive work. And it ruins the connection.
Let's put it this way: I cant even perform the Speed Test app half the time because the connection gets interrupted and dropped. I've had less than 50% success rate with finishing that test, and I usually only succeed by timing it based on the switching.

Lets see... HSPA and 3g = the same thing. You claiming your Nexus S switches between H and 3g is total utter BS. The H moniker in the notification bar is ONLY a reference to HSPA+ otherwise known by carriers as 4G.
Nexus S does not, never did, never will, switch between H and 3g. It just doesn't have the hardware. Since you are obviously a liar or just wrong, I discount the rest of your post as well.

The Nexus S shows H when using the connection and 3G when not.
AOSP sees UMTS as 3G and HSDPA/HSPA/HSPA+ as H. It will sit on UMTS until you are using mobile data, then it will switch to H.
So yes, the phone can switch between 3G and H while being used. HSPA and variants ARE 3G, but are seen as 4G, thus H. It doesn't even sound like you had a Nexus S so how would you even know what the status bar does?

LOL, with all due respect, you just made yourself look like a fool. If you actually owned a Nexus S or looked up its specifications, it is capable of 7.2mbps HSDPA (H, or sometimes described as 3.5G), whereas UMTS is described at traditional 3G. HSDPA was and has never been considered 3G. It's definitely a step up.
Traditional 3G has never been capable of 7.2mbps downstream. I invite you to do some research here regarding the differences. I'll assume since you had time to time to craft a clever little response, that you can take time to read up on it.
Again, had you actually owned a Nexus S or researched it, you would have found that it typically stays on regular 3G (UMTS...NOT HSPA) when not very active, and switches to H (HSDPA).
Again, had you actually owned a Nexus S or researched it, you would have found that in the System Settings, that network mode is easily found, and either displays HSPA (H/3.5G) or UMTS(3G).

I don't think that's ever been up for debate. However, the stock ROM displays HSPA and HSPA+ connections as "4G", and so do some of the modded ROMs. I'm not here for a debate on what's true 4g. This thread has somehow transformed....

I have this problem with my phone as well. I just want to throw something else out there also.
On my Nexus one when I had CM7 depending on what I was doing it could display 3g change to H. The thing is though that when 3g was displayed you actually had no data connection.
It seems something similar is going on here because the behavior isn't a slow down in the connection speed rather it's an actual break in the connection (downloads stop, speedtest does nothing, etc.)
We might not have a problem with the phone switching back and forth between 3g and 4g. Rather the phone could be switching from 4g to nothing to 4g. Only it's so fast the icons don't display the whole story (this is my personal belief)
You can see the same type of behavior when switching from WCDMA only to GSM Only
It starts at H
Then briefly 3G
Then no letter
Then E
I've tried to find a way to get the phone locked on 3g but I can only get 2g or 4g.

I can't remember whether you've mentioned this somewhere else, but what radio are you using? I'm curious as to whether you received a phone that didn't get an updated to release radio? I haven't had any problems.
I'm on 0.16.31501S.02
Also, I NEVER see 3G on my phone. I wonder if that actually helps my situation. I'm mostly always at full 4G, but will sometimes drop to 2G, or even G, depending on whether I'm in a shielded area or passing through a dead zone. I wonder if this could actually be working for me/against you?

I can't remember whether you've mentioned this somewhere else, but what radio are you using? I'm curious as to whether you received a phone that didn't get an updated to release radio? I haven't had any problems.

I only go between 4G and 2G when in fringe areas as well. Haven't seen 3G once.

Solved my problem
I had the same problem of my Galaxy SII switching back and forth between data types. I had tried putting my iPhone 4 SIM into my Android (with an adapter). Turns out that my problem was with the SIM. I needed a different SIM for this type of phone.
Just positing this in case it helps anyone. Try visiting your carrier and ask for a different SIM.
Flash my T-Mobile ROM and it'll fix the issue.
I keep seeing my 3g connection dropping completely. I'll be browsing the web and im not moving at all and all of a sudden the connection is gone. I first thought it had something to do with the connection optimizer but it doesn't seem like that. Did anyone else experience this or know a solution to that?

i noticed that this was happening when mostly when the phone was going back and forth between 3g and lte. so i changed the mobile network settings to cdma only instead of cdma/lte and it was much steadier.

by changing it to the CDMA setting you are only going to be on the 3g network.

So there is really no solution besides going to 3g only. But it really isnt jumping from lte to 3g . It will show 3g and all of a sudden nothing. Sometimes even showing me the little x over the bars.

This happens in an area with partial Spark.
Mine does same thing because I have 3 towers all equal distance from me. 1 is Spark other 2 are not.
If you travel to another location you probably won't see the issue but in short from talking to some eng. the phone is doing 1 of two things.
A) It see's an LTE signal and as LTE is primary it starts to try to connect to it but before it fully does (thus why you never see LTE icon) it realizes it doesn't support the switched fall back required to allow Spark phones to get calls while on LTE so it kicks you back to 3g. This process continues to repeat :/
B) The phone see's an weak LTE signal, as is primary starts to connect but before it fully does the signal is determined to be to weak and falls back to 3g.
In both cases the phone possibly would never show you the LTE icon as that will only show once fully established and it doing this jumping back and forth causes 3g to go and die where forcing CDMA fixes.
The other downfall to this is it KILLS the battery.
Connecting to WiFi won't help with the battery part either as it still does the jumping around.
Your only option is really force CDMA mode only when in an area like this, for me, this is at home only, or live with it and lower battery life until they upgrade the towers all the way.

Thank you for the detailed explanation. I just got off an hour long phone call with sprint with them trying to explain me my phone is defective and my wifes as well. Then when i told them it isn't they started going into the "Yeah its our network" mode but then came back saying she put a ticket in for me and my wife to get the phones repaired. I told her I don't want that to stop worrying about the phone and to send me an air rave. Problem at my house solved lol. They are sending me an air rave

You could try turning off or on, depending on whether you have it enabled already, connection optimizer

Hate to share the news but that won't solve your problem, it actually could make it worse as it's now another signal to bounce between.
4G IS always priority when enabled, so regardless of you having a "tower" inside your home now, that does not provide 4G, so if the phone's seeing one that does which is what's causing the problem your issue will remain the same meaning you're forced to put the phone in CDMA only mode still.
The problem isn't with the 3G tower or 3G signal, the problem is the 4G signal being detected but not yet compatible with SPARK due to missing the circuit fall back feature, which the phone doesn't know until it attempts to connect. In some areas where it's partially setup the phone can connect to 4G and just calls won't work, in other areas it's disabled or doesn't exist and this problem happens.
Your solution will simply need to be put the phone in CDMA only mode when in a troubled area only, or just leave it in that mode and have no 4g until everything is upgraded better, or deal with as is.
