hey everyone
so my G2, which I absolutely love, has been having a problem lately. in the first week it happened maybe once and i didn't think much of it, but since Friday it's happened like 8 times now. I'll be sitting there with my G2 and all the sudden I have no service whatsoever. Just an x on the signal strength indicator. 1 or 2 times it has come back after a minute or two, but the other times I had to turn the phone off and back on. the weird part is I'm not moving at all, totally sitting still, but when it comes back on I have FULL bars with HSPA+. so it's not like I walked into an area that didn't get good reception.
any idea what's going on? i looked around but didn't see other people having this issue. any ideas?
thanks
alright well at least i'm not alone. i remember that rumored OTA update was supposed to have some radio bugfixes. maybe when the real OTA update comes it will have something to fix this. i hope so.
I have been trying to diagnose this issue on my phone too.
By any chance, do either of you have your BT on at the time?
Happens to mine as described and I have never turned on bluetooth. However this would also happen to my G1 so I think its a network thing personally.
Yeah, it definitely is. I have 2 areas that it happens in, both are while I am in my car and I have BT on in my car. When I ran it without BT, did not happen.
I have found that when I am in those area's, turning off 3G stops it entirely, even with BT on, so when in my car, I set edge and still use my BT and problem is gone.
I hope this is temporary and an OTA can fix the handoff from 3G to Edge and back better so that I can stop this, but this works well enough.
Mine has done that also, maybe once a week for the past 3 weeks.
Judging by the other problems you can have Id say this one isnt that bad. Especially if it only happens once a week haha. This is the only problem I have with my phone.
no bluetooth...
no no bluetooth on, i never do actually... but also my G1 never did this, which makes me think it's NOT a network thing, but I don't know.
also I'm sure this is just coincidence but it almost always happens when my girlfriend is nearby with her T-Mobile Blackberry Curve. i know it wouldn't make any sense, but she's sitting there on the same network with full service and all the sudden my G2 loses service completely, right next to her... although it's not always while she's there, but like the majority of the times she's been there.
I just started another post to check on something, I have widgets that show me when I am connected to 3G and when I am connected to H. I have noticed that the phone is activity managing that connection. In other word, it is in 3G until data is transfered then it goes to H. I wonder if when we are in areas of "questionable" HSDPA signal if this hand off is causing the problems.
I have seen a lot of op's say that there problems come right after some data activity?
Just a guess a this point
i saw someone mention in another post that it happens after/during a text message alot of times. i haven't noticed that myself, but that's something to think about too.

What I've heard is that the phone will stay in 3G mode until you begin using data in order to save battery life. Makes sense to me.
My wife and I both have the mt4g and have been experiencing intermittent data interruptions at home, where we have a strong "H" signal. It will happen on one phone, while the data continues to flow on the other phone, suggesting a phone issue vs a tower/connection issue.
Basically what happens, when doing something like downloading an app or playing slacker radio, the up/down arrows under the "H" become less solid/consistent and the download or slacker radio stops. When this happens, I've tried opening the web and am unable to get any websites to load (I get the kind of 'unavailable' error, as if I have no data connection). After like 2-10 minutes, things typically resume to normal.
Again, this will occur on one phone while the other continues to operate normally. Btw, got the phones on Friday afternoon and neither of us have received the 2.2.1 update. Any ideas on what the issue might be?
I've had that issue occasionally on every Android phone I've owned. It's never happened THAT often, so I've kinda dealt with it.
I am also having this "problem".
Sometimes I'm updating an app, others, while browsing the web.
I've had this happen once, but I rebooted and all was good again.

I have just started experiencing this issue recently too. I am gonna step out on a limb and say it may have something to do with the update because I never had this issue before it was pushed to me.
Edit: sorry went back and read your original post and saw that you didn't do the update- it is anyones guess then.

I had this issue on the second day, it seems to have vanished on it's own. I kept having to enable and disable "airplane mode" to get it back to working instead of rebooting.
My next plan was to toggle the network connection off/on when this happened and see if it cleared up the problem immediately (probably similar effect to toggling airplane mode). I actually just now got the update pushed, but it seemed like the data connection was stuck during the push (over 30 mins nothing was happening, and data download arrow not working, web not working, etc.). I rebooted and turned on wifi, and update was ready to install within a minute or so. I was hoping the update would fix the issue, but sounds like it persists at least for some. This happens far too frequently for my taste. I'm thinking about asking for replacement devices to at least rule-out defective units. I guess I'll see how it goes for the next day or two and report back.
I'm having the same issues with my G2, so I'm interested to see how this device is doing. I might consider switching.
I've still been having this problem, and it still seems to be occurring relatively frequently - like maybe every 15-30 minutes or so, and with it more likely to occur if I try to do multiple things at once (e.g., some combo of browse, download, slacker radio, etc.). Btw, this is happening on mobile data, not wifi...haven't really tested wifi much yet tbh.
I used widgetsoid to give myself a mobile data toggle to use when I had a problem. It seems like when the data connection gets locked up, tapping this toggle fixes the problem fairly quickly...but it is kind of annoying to have to tap this when it happens, and it's not always clear when there's a minor hiccup in the data vs a stall that's going to require me to 'reset' things.
Also, I noticed that the widetsoid mobile data toggle actually has the same effect whether you are toggling it 'off' or 'on'...either way, it turns off data momentarily, then the data indicator reappears and the data connection resumes. Anyone have a suggestion for something like widgetsoid that will actually toggle mobile data off and keep it off when in the off position?
If you use the sense launcher there is a network connection widget.

Keep in mind that the G2 and MT4G are the first two HSPA+ phones ever. There are bound to be some kinds in the network in the beginning, but I would bet they get ironed out quickly.
Have you guys ever noticed your phone slowing down as it constantly switches between 3G and 4G? Living in Austin, I probably make the switch a few hundred times a day, depending on what building I'm in, and where my phone is sitting.
There are plenty of times where I pull my phone out of my pocket, and it's very warm, and running horrendously slow. I typically notice the 4G icon, so I disable it altogether. Usually within about 30-60 seconds, my Evo is responsive once again. I have used every stock ROM, and about 6 custom as well. All behave IDENTICALLY.
I really have had only one instance where 4G was useful, and that's when I was at a restuarant, and I wanted to tether my laptop. I was able to get a solid 4G signal, and it seemed to work great. I did find out, however, they had free WIFI, like almost every business does these days.
Not so sure I'm really sold on the 4G stuff, even though almost everywhere I go in Central Texas has good signal. It seems to waste far too much CPU as it switches back and forth, enabling/disabling radios, or whatever. If I'm in Dolphin browser, and it switches radios, the phone appears to lock up sometimes... quite annoying... happens all the time.
Anyone else with similar issues? I know most people aren't even in 4G areas though.

Well in general I noticed this cpu spike on my sense roms even when it was turning 3g back on after leaving a wifi spot. I really blame HTC's inneficient code, since CM6 handles this so much better. I did try 4G out in my area and thought it was better on my cpu than 3g was though.

After you use 4g, you need to reboot your phone. The 4g icon may go away but the phone is going to keep searching for the 4g signal. Known issue/bug. You can ssearch the forums and find lots more info on it. Free app called alogcat will show you this by conintuing to try and connect to winmax.
I live in Austin, too and use the 4g toggle quite a bit, especially closer to town, while at concerts or football games.

That explains why when I leave 4G on regularly, I have to reboot my phone at least once a day from slowdowns... If I leave 4G off, I tend to last almost a week before I get frustrated enough to reboot.
Really disappoints me, and I was hoping I was an isolated example. I had done several searches for this, and didn't see any results. I guess because not many people have 4G, and those that do probably toggle it on specifically for use when they are in a 4G area. Seems to me that 4G is only useful when you are sitting still... if I am in the car and I leave it on, my phone get sluggish as hell, and my battery can be dead in under an hour.

I believe the bug only occurs if you have a 4G widget on one of your home screens. You may be able to remove it and turn on via settings as a workaround.
Correct. Don't use the widget to toggle 4g. Go into settings and turn it on that way and you wont get the lag.

I had a ROM a few weeks ago that didn't even have a 4G toggle... I think it was AOSP. Didn't like it much and came back to Sense-based. No effect on the CPU bogging.
I live in houston and not in the city, I get this every day....i stopped using 4g a while ago...it'll get better with time though

Only turn on 4G when you are actually going to use it than turn it off. Most web tasks do not require 4G and it will improve battery life.
theres a couple guides out there for editing your 4g in and out times, signal requirements log in delays, ect. those will help big time, and you should be resetting your phone once a day anyway for good usage, also it helps to if your using 4g, turn off the mobile network because its pointless to run both radios at the same time [helpful if you have myns with the data in the notifications menu for easy chaning]

Can you confirm that turning off the mobile network from the power-button drop-down menu actually does anything? On my phone, when It detects 4G or WIFI, the 3G icon disappears for a bit, then turns into the new one. That leads me to believe that it automatically does that for us...
I use 4G every day. I have "mobile data always on" set to on demand, so when I turn on 4G via the Extended Controls widget I use, 3G automatically turns off. Haven't had any phone slow down since I started using this method. When I turn 4G off, 3G automatically restarts, so one or the other is always on. I keep 4G always on at home, and only turn it on while out if I'm watching using large amounts of data.
At some point I made some changes in how long my phone will try to stick with 4G when there's a strong 3G signal, and that helped with streaming music/data while on long drives.
The only time you should see CPU usage is when the radios are toggling on, and off. Also when you turn 4G off, yes if you look in logcat you see that WiMAX is doing something but that's about it. IIRC it is checking the status of the 4G radio to see if it is on. The radio is off though, verified by monitoring the current drain in almost real time. The 4G radio draws about 200-300mA itself. The "4G Toggle for EVO" app by Jason Calhoun (see Market) so far has given me the least amount of hassle of the 4G widgets out there, and most of the time I don't have to worry about turning off 4G after a reboot.
On average with my current configuration I draw about 254mA (3G /display @26%/doing nothing), 188mA on WiFi. The lowest I've seen was 89mA (just coming out of sleep), and the highest I was ever to draw was 996mA (everything on, turned up, playing Angry Birds).
Under 4G settings make sure network notification is unchecked, if not the phone is forever scanning for a signal, especially if you're toggling bad. If you have it unchecked even when you use the widget it will only search the initial time when you turn on the widget. Can't say this will solve the issue, but at least stop the phone from continuously scanning for a signal should help. You can only uncheck network notification while 4G is checked. Hope it helps cause i'm in the centex area also(Waco). It helped for me when told to me by EVO owners.

I've also noticed my Evo seems really sluggish when 4G is on. Like, to the point that I always leave it off, because it makes my phone barely usable sometimes when it is on, even when I am standing right next to the 4G tower. I read through here and I'm going to try removing the HTC widget for 4G from my home screen, maybe that'll help.

But until/unless you reboot the phone, the WiMax continues to check the status of the 4g radio. So that would make the phone sluggish. Even with no toggle on a home screen or any screen, just doing it manually, when turned off it keeps scanning. Right Thats what alogcat shows until the phone is rebooted.
I have turned off 4g and gone about my business and been fine - went almost 30 hours on one charge and had 4g on for about 2 hours of that, so it may not be a major battery drain amp wise, but it appears to continue to scan even when turned off.
From a 2-day trial I can definitely say that my phone seems much more responsive since I removed the 4G widget. I replaced all the HTC radio widgets with the stock android one (which, of course, doesn't have 4G) and my phone seems very responsive. At the same time, I turned on 4G via the settings menu and I've left it on. It seems to be working well.
This is a topic that hasn't been clearly covered so I'm posting it here.
The new update talks about new 4g scanning functionality. Has anyone had any time with this or any basis of comparison for 4g behavior before or after the update?
4g has to be one of my biggest gripes on this phone pre-update as it was the main reason why I bought it and it's connection strategy ends up using more battery than anything. Just wondering if this new "scanning" feature improves that at all or makes it worse.
Interested in this topic myself.
bump.. yeah I was wondering about this as well.
Initial observations:
When wimax radio is on a couple of scenarios happen.
- Wimax radio on but no 4g service = wimax state is changed to "disconnected" meaning it behaves the way it will when wifi is being used (it doesn't scan so it uses very little power and when in the disconnected state the dc connect errors don't flood logcat; dc connect errors are still present in this update). Before the update if the wimax radio is on it will constantly scan for service even when there is no service available and it will scan every x amount of seconds unless a wifi connection is present then the wimax state is disconnected if the wimax radio is on and a wifi connection is present.
- Wimax radio on, no wifi connection = wimax state will remain "disconnected" until the user taps "scan for service". If no service is found wimax state reverts to "disconnected" meaning the radio is on but not scanning (before the update the radio will constantly scan while it is on) as opposed to off and flooding logcat with dc connect errors in the background.
- Wimax radio on, no wifi connection, no service = notification saying "4g radio is on" (only saw this notification twice mainly because I didn't want to sit and watch my phone tell me the radio is on). Wimax state remains "disconnected" (not off) and will only scan when "tap to scan" is pressed.
What does this mean? Whether you have 4g service or not you're better off leaving the radio on as it will always revert to a disconnected state when no service is found during a scan. Leaving the radio on keeps the dc connect error flood from happening in the background which some people attributed to huge battery drain. As long as the wimax state is "disconnected" and you are not using a wifi connection it does not/will not scan until you tell it to. The constant scan every x amount of seconds when no service is found is what drained the battery for most users.
So what happens with the new update?

He just told you in the post before yours.
I guess my new question is this:
Running the previous build, I would just leave 4g on so that I always had it if it was available. My office building has poor 4g signal penetration, so it cuts in and out frequently depending on where I walk. With the new update, if I walk into a portion of the office where my 4g drops, will it not pick back up automatically when I come back into a good service area? Am I going to have to manually tell it to "reconnect" by tapping the scan button every time I hit a dead pocket?

That's what appears is the new behavior of the wimax radio. It's a two-fold scenario and I believe sprint did this more for customers convenience since people with evos would more than likely keep track of what parts of town has 4g service.
It saves battery somewhat but requires the user to have to scan/rescan for service. I never turned my wimax radio off anyways prior to this update and I only flashed the update last night to check if there were any changes that I was hoping for.
Anything positive you've seen from the update? Are you going to run the new method or revert back to the old? Have you seen any battery improvements as a result of this new method? - it sounds like battery is why they changed it.
This update is actually LESS convenient for me as I now have to manually connect every time I want to use 4g considering how spotty the service is even in my "launch market" of Dallas.

For the most part sa is blanketed with 4g service so I am like you in that I have to rescan when I move.
Time will tell for me. I plan on building a rom later tonight with the new update and testing the kernel. I use extended batteries (seidio and sprint) so I don't pay attention to battery life anymore. I'm more concerned with useable performance.
After I build the rom I plan on seeing if I can get the wimax radio to revert back to auto scan. Again time will tell.
Alright well thanks for all the info. I've got a seidio battery on the way, but the log file thing is what piqued my interest. I'm about to flash the rooted version of the stock rom and give it a go.
I just flashed the latest - Is there not a widget or shortcut I can put on my homescreen to initiate the scan?

I didn't find a sense specific widget. I used lpp to make a homescreen shorty straight into the 4g settings window.
what is lpp?
Launcher pro plus. Or just the regular free launcher pro will do it for you too. That's just me. I always remove sense entirely whenever I tweak the rom and lpp is my home launcher replacement.

So what if you are in a good 4g area (also not using wifi) turn on the 4g then turn of the 4g does it go into the dc connect error flood? I rarely use my 4g but I avoid turning it on unless i plan to do a reboot to avoid batt drain issues. I am running myns rom so i havent tried to update anything since the latest update. Curious if the new update still forces a reboot after using 4g.

Yes you mentioned in the last paragraph about batt drain issues but I dont see how leaving 4g on solves this issue. Leaving 4g on all the time will probably drain more battery scanning for signal (when not available) and use more battery when using the 4g signal then when on 3g. I personally think if you use 4g after you are done with it turn it off reboot then go back to using your phone normally. Yes its a pain to reboot but imo you will get better battery life using this option then the options you are suggesting...thoughts?
Either way i tested it out for myself, i updated to latest radio and still getting the dc connect error flood. From my reading on this issue from other threads it seems this is an HTC code fix not an android fix...but that is speculation.

Lastly I read your response several times..maybe its not as clear as you think it is. Glad you wasted time writing that response then simply answering the question. Dont assume people dont read and search the forum. So congrats on sounding like a douche..be better to discuss this issue then put your great reread comment up.
I walked into a room with no WiMAX signal, 3G kicked in and the notification "Tap to scan" showed up. However, I did not touch anything and after a few minutes, my phone was once again connected through 4G.
So it will actually re-scan and reconnect eventually, even if you don't manually tap to scan.

Yes its a pain to reboot but imo you will get better battery life using this option then the options you are suggesting...thoughts?
Either way i tested it out for myself, i updated to latest radio and still getting the dc connect error flood. From my reading on this issue from other threads it seems this is an HTC code fix not an android fix...but that is speculation.

Lastly I read your response several times..maybe its not as clear as you think it is. Glad you wasted time writing that response then simply answering the question. Dont assume people dont read and search the forum. So congrats on sounding like a douche..be better to discuss this issue then put your great reread comment up.

You need to read better then. I distinctly said the dc connect errors were still present in the new update.
I distinctly said the wimax state is changed to disconnected when there is no service. I also explained what happens when the wimax state is disconnected.
BUT, since you seem to be adamant that you did in fact read what I posted I will spoon feed the info to you.
When the wimax state is "disconnected" it does not do anything, it does not scan and the radio itself is not off. It is in a "sleep" state.
I said the dc connect errors were still present in this update and I explained that leaving the 4g radio on will revert to a "disconnected" state when there is no service available. Since it doesn't scan in the "disconnected" state it is not using battery. Because of this, the radio is not off and does not flood the background with dc connect errors. In the "disconnected" state the radio does not scan for service and the impact on battery drain is minimal.
Now, if that isn't clear for you then nothing will be. I invite you to search my original unedited text again and show me that I did not SPECIFICALLY state that the dc connect errors are still present in this update. When you find it you will know that it is you who has not read the text properly, not me.

I walked into a room with no WiMAX signal, 3G kicked in and the notification "Tap to scan" showed up. However, I did not touch anything and after a few minutes, my phone was once again connected through 4G.
So it will actually re-scan and reconnect eventually, even if you don't manually tap to scan.

I will test this later today if I can. Like I said earlier in this thread sa is blanketed for most part with wimax service so I will have to force this scenario but it's great that it rescans for you.

this is the part I dont necessarily agree with as ive seen my phone scan when no service is available (otherwise how would it automatically lock back onto 4g) but as the next post said his 4g kicked back in so does mine leading me to think what you are saying isnt correct about it not scanning and draining battery, i could be wrong but i will look into that as well

Doesnt add up, if the 4g reconnects automatically has to scan to reconnect to 4g not going to magically know that 4g service is available again

Funny you say search your text again when apparantly you didnt read what i said in my last post saying that you mentioned the batt drain issue (referring to the dc connect errors) never said you didnt speciffically state that, geez dude relax and realize I am trying to troubleshoot the situation as well
Ever since I got a replacement phone Ive had this issue- while on the Sprint network my signal will randomly go from full to nothing at all. Yet when I use roam control to go into roaming, the signal always stays at full strength
The other thing I noticed is that when I dial into the 3282 menu, someone elses username is there instead of mine. When I run connectbot and use getprop, no MSL # is there either
Anyone know whats going on with the phone and if this can be fixed?
getprop ril.MSL
It is filtered from just getprop.
My signal has always done that.
Updated profile may fix the user name?

Thanks that command did the trick to get the msl- I was able to go in and manually change the username now.
Is there any settings in the data menu to improve the signal? Its almost like its jumping back and forth between a good and bad tower?
Not that I know of. That is what I suspect is the case with me as I have about 3 towers that are surrounding me from various sides and I think it is hopping between them... not sure there is anything to do for it but I haven't really seen any ill effects from it.

The weird thing is it never used to do this before when I first got the phone. When I was in the same areas the signal bar was always full and would never drop. I wonder if its a tower issue or something they changed with an update.
Sometimes when people call me they say it goes straight to voicemail though which worries me
Could be the modem. Some people think el30 is not as good as ei22 or ec05. Maybe try some others.
For calls calls going to vm, that can happen if you are using data in a 1x area. Also can happen if you have accidentally switched on ddtm in call settings.

This is going to be plain and a tad bit retarded but a solution is WiFi, as far 3G and 4G mine has always done this but i can testify that in my house i used to get ****ty service like 0 to 1 bar when i was on EC05 i switched EL30 now to FB15 and say much more improvement more consistent to 3-4 bars.
PRL updates could help if you roam around there. newest as of today is 60685
I've been having this problem too for about two months now. But as you said roaming works fine so I just assume it's a sprint tower issue and force roam whenever I'm on wifi.
I have had this issue for a year or so... started a while after I first rooted.
You can hold my epic in one hand, my wife's epic in the other... her bars stay steady, maybe fluctuate between 2 or 3 bars occasionally... mine randomly and erratically jump from 2 or 3 to nothing, stay there for 30 seconds or so... and jump back up.
While its annoying and distracting, I've never had a problem with dropping calls or losing data. I even took the phone apart to make sure the antenna had not come loose. Problem persisted over several roms and several modem Odin flashes, just won't go away!
Mine does the same, it'll have full bars, drop down to nothing, but my 3g/4g still work fine (off wifi)... i just ignore the signal bars because most of the time my data still works, albeit a tad slow.
