HD2 Radio Has Horrible Instability

Is anyone else here having similar problems with the radio on their HD2? Mine seems to crap out severely when it comes to 3G. I have notice dhtat just about every time the phone is powered on, it will turn the data connection in the settings off by default regardless of It's state when the phone was previously powered on.
Also, I have noticed sometimes the phone will sporadically switch out of 3G mode and into phone only mode and I must go into the settings menu and re-enable it.
Also, Sometimes (The phone has done this twice today so far), the phone will still indicate that it is in 3G mode but when I attempt to browse the web it will return a page cannot be found error and the only way to fix this is to go into settings, disable and then re-enable the data connection.
My current radio version is 2.08.50.08_2. Is there something better out there?

I had the same problem with the data connection shutting off. I downloaded HD2Tweak and it helped keep it on.

It's been a while, but I think I got it here. It was the English version.
http://www.montecristoff.com/hd2tweak.htm
Under "4. Data", I turned on Internet, MMS and Data to be on permanently. Worked like a charm. First day, I had 13 hours straight of data connection. Before using HD2Tweaks, I never had more than 20-30 minutes.

I've noticed today the 3G connection went from full bars to none and also no phone bars.. and it reconnected again.
Sometimes it will not reconnect to signal for a while after I leave underground train station.
In areas of weak-medium signal strength, I've noticed it switch between E and 3G a lot and drain battery much faster.
The signal reception is generally excellent in the city, except if inside a building with thick walls, so I don't understand why it has signal issues when outside.

[Q] my G2 loses service, restart brings it back

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.

leaving 4G has always bogged my CPU

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.

WiFi Dropping

I have the sleep policy set to never yet my WiFi at work keeps reconnecting every time i power it back on. My Evo4G has the same settings and doesn't drop the signal.
Ideas?

I'm having the exact same problem!
When I let my tablet sleep, after turning the screen on, the status bar says I'm connected to WiFi, but the bars are grey, not blue. Browsing the web works and YouTube as well, but apps like Talk keep saying I'm offline. After waiting a minute, it signs me in.
I have it set to never disconnecting WiFi, I'm not sure why it's doing this.

Same problem here. I returned my first Galaxy Tab 10.1 because of this. Sadly my replacement does the same thing.
I'm wondering how common this is or if returning it again would just be a waste of time.
It's particularly annoying because I like to stream after a while when the display is off, the streaming stops (wifi apparently dropping).
Seems like it is always one dang problem after another with each Honeycomb tablet I've had. *sigh*

Am I to assume by lack of response that almost nobody else has this issue? Just curious because it seems odd I'd have this problem with two tablets. And trying to decide if I should return and try a third time. Hate to keep returning them though if it's just a normal glitch with this tablet.

Same problem here, but only on my EAP network at work. On my home network (WPA2 personal), it works great.

I have this issue too, I seem to be connected but bars are grey. I tap the wifi, which takes me to settings and once I tap on my my access point which already shows connected, it lights back up and the bars change back to blue. Mainly an annoyance for now.

I had this same problem, the only way I found that is consistent is using Bluetooth.

Anyone know of a good way to reproduce the problem on demand? It happens often. So I was going to return the tablet to Fry's Electronics. But now they've gotten super anal and won't even let me exchange unless I can duplicate the issue in store.
But it seems to happen at random times when the screen has been asleep for a while.
And I probably will do my best to avoid shopping at Fry's in the future as well.

Happens to me too. It definatly is annoying. Hopefully they can send out a fix when they release the touchwiz ui.
Sent from my white Samsung Galaxy Tab 10.1

It's not like I get disconnected from the net, although I see the grey bars, I can still surf the web and junk, but some apps log me out like I mentioned before. It used to happen all the time, now i only happens at times.
To see what I'm talking about, let it sleep for like an hour or two, and then launch Google Talk. It says you're offline, wait a bit and it logs you in again

Okay, that must be what is happening to me. I notice the grey bars all the time and a bit of lag once I pick up the tab and try to connect to some network resource. What I've discovered is that if you connect to a remember wifi spot (home) then let the device sleep and then move to another remember wifi spot (work) it just disconnects and waits for you to unlock the device before it even tries to reconnect.
It's driving me crazy, I take it from home to work and us to use it to keep me updated on emails but now if I forget to unlock it it won't scan the remembered wifi network that I'm now on, it just stays dormant until I unlock it which means no email notices or anything pop up.
There's got to be a setting or something to say always scan for networks, I have "never" checked but that does nothing in my opinion.

Phone sometimes disconnects when using WIFI

hi, sometimes when i look at my phone, usually after being on wifi the phone shows no bars.
sometimes it comes back on in a min, i tried airplane mode but it wouldnt work. so i restarted it and worked fine.
not sure why it happens, does anyone else have this? could it be due to some Wifi calling setting? not sure why phone seems to just cut off.

anyone have any idea why this may be happening?
does it turn off radio for wifi calling somehow or? just random.

I have a similar issue, but not equal. Sometimes, when I try to connect to the network I always do (home), it simply doesn't work. Scanning - disconnected - scanning - disconnect. Only a phone reset fixes this.

I had a similar issue a while ago and sent Mine back to the seller but the seller claimed neither they nor Samsung could find a problem with the phone. Thankfully The seller sent me a replacement which no longer gives me this problem so it may be the handset, though it could also be the setting/Conflicting app. Someone reported here his problem Was solved after adjusting a w ifi regulating app

i have a 3-day old gnote and i started noticing this problem after i have my phone rooted. the wifi icon stays on but there's no internet connection. turning the screen off and waking the phone after a minute solves the problem but its annoying to be losing connection when you're needing it. i'm on stock KKA.

Not a user error so need to contact Samsung-don't think is anyway

I have a somewhat similar problem. When I am using wifi for somewhat long time, I am unable to connect back to my 3g. Or if I was on 3g connection and I move out of coverage area for a little more than 10 minutes, I can't reconnect to 3g. Only 3g connection has this problem though, everything else works fine.
If I restart the phone, I can reconnect. Setting to airplane mode and resetting doesn't help. Neither does resetting the mobile network operators.

Yes, the problem seems to be software related since there is no actual problem with receiving 3g/phone.
yesterday i drove back 10 hrs and streamed music/radio the entire way with only a few tiny interruptions in reception.
but often still if i just take my phone out of my pocket, the "phone" part will be off and usually turn back on within 1-2 mins.
but this is quite annoying since sometimes il literally be waiting for 1-2 mins to place a call.
my phone is "not" rooted.
