Signal randomly is gone - HD2 Android Q&A, Help & Troubleshooting and Genera

I have been running android on my hd2 for a while now and i love it. I wish the screen was more sensitive and the calls were louder. dsp manager never works for me. but more importantly i noticed a huge problem.
Randomly when i hold the phone on power it on from sleep mode. my reception goes to X with no bars at all. Then a few seconds later full service. This is it my normal spots i use my phone while my vibrant shows full service. Is this a known issue or is there something i should be doing.

same problem here.. and i have 3g signal only few times, in area with good signal.. do you have any workaround for that? is that because of ppp? i didn`t have this kind of problem before, now on every build..

WM6 worse signal reception

Hi all, I have WM6 almost for week now and first I was very pleased by it as the SD card issue seems to be fixed, but I started noticing a weird phone behavior. For example, Sometimes I'm not able to turn off the flight mode, sometimes my phone stops showing signal and I have to soft-reset but the most annoying thing is, that the signal reception seems really weak. I'm not able to make a call from many places where I could before. Just entering a building makes the indicator to drop half down. Does anybody have the same experience?
For me, the signal recepetion is the same than Windows Mobile 5.
No changing

HD is off time

It happened virtually the second day I had my HD - I looked at the clock and the time shown was one hour and some minutes off. I did not pay any attention at that time. Since then, I have been synchronising it with my PC, so I guess it was updating its clock automatically. This until today... I did not sync and about midday, I noticed again that the clock was off by more than an hour. Mind you I have thicked the option of it syncing the time from the operator.
Any thoughts? This is really annoying since I rely solely on HD for alarms... especially in the morning.
Thanks in advance
off time...
It happened to me too, twice even. But not on the same
day but days apart. What I discovered was if you use
3G, then the trouble starts. In my place, 3G is unreliable,
and the signal strength goes in and out, and sometimes,
no signal. If no signal, then no time sync with operator.
I switched to GSM and everything is ok again.
Anybody here having problems with late time under 3G??
Interesting observation regarding the 3G connection to time. I usually have it on GSM for battery reasons, but sometimes I switch it to 3G. However, today I believe I had it constantly on GSM... and it did happen. The strangest thing is that it goes off not by minutes but more than one hour (at least in my case). Anybody else with a similar observation?
time inaccurate
Hmmm, I don't have the problem when on GSM at all.
However, I also noticed that if you pullout your phone
from your pocket/bag using the touch screen area instead
of the sides, you automatically activate the time configuration screen area. Maybe this is the cause. Try
observing on how often you grab your phone via the screen
instead of the sides, especially if you are in a hurry or
unaware of it.
I have the same problem with clock. The phohe changes time itself, happened three times to me. Does anyone has the solution to this problem?
I have this issue when I am out of GSM coverage (which sometimes happens when I have the phone with me in the bedroom at night, Orange coverage poor here).
Somewhat annoying to find the clock 30 mins late

Dropping Signal

Hey there people.
Hoping I've not missed an existing thread.
I'm having problems with X10 dropping its signal seemingly through its own free will. Had phone since mid april and not had any problems with. But the other week me and the missus noticed occasionally i wasn't receiving texts she had sent me. This happened every now and again for a few days. I then noticed when i picked up phone it'd show signal on 3G as maybe 2 or 3 bars then suddenly drop too nothing, showing the little x indicating no signal. After a few seconds up to a min it'd pick signal back up and work again. I no for a fact its not me been in an area without 3G coverage because it happens at work and until this started happening i got a strong 3G signal there. It doesn't seem too switch too edge either any more. Its set too GSM/WCDMA prefered. I'm on 02.
Anyone else have similar problems or any clues on what the problem it.
Cheers

[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.

Data dissappears during phone calls? Realization time

Has it always been like this? Flashed a few roms and radios. But I think I never really thought about it or noticed it until now and it's really bugging me. I've read a few topics about 3g and 4g being "parallel" to our voice calls so we can't have both? I don't quite understand any of it.
Can someone tell me it's just my phone so I can try to solve the problem, or reassure me that we can't have both at the same time so I can sleep better tonight? lol
Thanks for any and all help!
Edit: Sorry meant to post this in the question thread.

ALL GSM phones that are connected to HSPA or greater should be able to talk and surf at the same time. I do it frequently personally. Do you know if you drop to EDGE/GRPS when you get on a phone call?
I am also having this issue but its strange that the guy posting above me does not face this issue - may be it is a hardware issue like screen and emmc since I already tried different roms and radios?. As soon as I am in a call I am disconnected from network data. I noticed only recently when I was in a hotel room working on my laptop (tethered phone to provide internet) and just when I joined a conference call, I lost internet. It was so embarrassing I couldnt curse tmobile and htc enough. The iphone ad about talking and surfing at the same time never made sense to me before this incidence.
my phone does this too, but its on and off. Sometimes it does, others it doesnt. I really have no idea what could cause it.
Let me shed some light on this....if you are on H will less then 2 bars and theres an E with 3 bars or more and u get a call the phone will switch to E but once you hang up then its back on H. But if H has 3 bars or more when a call is received then I will stay on the H network and allow talk and data at the same time. Theres no hard ware issues trust me. Hspa is preferred but if there is a stronger signal then the phone switches. I hope that makes sense. You can not do data and talk together on E but you can on H.

Or, to put it in other words: when the phone is in a call, it'll hop to the "best sounding" base station, and if it would happen to be the old GSM/GPRS/EDGE base station - the data will drop. The missing bit is: once it drops - it isn't re-negotiated during the call, only after it. Thus, if the phone hops to EDGE base station even for a second during the call - you won't have data from this point and till the end of the call.
Perfectly normal behavior.

This is definitely not the case. I have tried multiple times with different signal strengths but it drops completely every time. I just did another test, I was on H at 3.47mbps with all full bars and as soon as i placed a call to my friend, the data dropped completely.

It's not about the bars you see, but the signal strength (and not only) your phone sees - which is way more complicated than just bars. Read my post above.
And it's not an opinion either, it's a fact. This is how cellular handoff/handover works. http://en.wikipedia.org/wiki/Vertical_handover
Thanks for the replies and insight everyone. Now I know a little bit more about how that handover works heh.
In my case, most calls were made from my office building. Yesterday, when I posted, I had the newest radio and data would drop immediately as soon as the person answers my call (not a steady drop from 4g-3g-Edge, icon just disappears completely). At best, I was able to download a few apps during a call (which was downloading before the call was made) but as soon my screen locked and turned off - the data was gone on wake and wouldn't turn back on until after the call was finished.
Went through 4 different ROMS yesterday with about the same results but I have recently reflashed RoyalGinger again along with the stock radio thereafter and it seems to be holding during calls, even on my ride to work this morning. I know this is against what most people have said in this thread but maybe I just messed something up on my phone with the new radio? Guess I'll stick to this radio for now. Thanks again everybody.
Radio is the one responsible for determining the best possible connection, and flashing new radio might change things.
I'm in a good 3G/H coverage zone, with new radio, and just tested - the data remained on during the call in any conditions, screen off, screen on, wifi toggling - still worked.

When I'm on 4g and turn the screen off the data turns off, normally after an extended period, which its good for battery.

This has happened to me since I had my blackberry 9700. My experience has been that it loses all data (H/3G/E), even in good H/3G signal area and won't reconnect until I end the call. However the data loss only occurs while on a call. While not on a call, just surfing the net or using data any other way does not cause lost data connection nor a drop from H/3G to Edge. I saw somewhere on these forums that switching to H/3G only will prevent this from happening. I've tried this and it seemed to help, but I haven't been checking on every call.
