Answering a Call

Just a quick question for you guys. When I receive a phone call (full signal strength) and slide the slider accross to answer the phone there is a long pause of silence before the call actually connects. Has anyone else run into this situation?
Nexus One running stock Froyo (At&t)

yes I have this issue: I answer and cannot get an answer on the other end but I can hear them saying "hello". After a few seconds we connect and they say they never heard me say anything even though I was saying hello back.
I have two Nexus Ones: one answers calls perfectly and has great sound quality, while the other has this issue you describe, along with low call volume.
I think in my case it may be a hardware issue and I may need to send it in to be looked at. Both running on ATT although the good device is the tmobile version and the problem device is ATT 3G version.

You think it is a hardware issue? I thought that it was like that across all N1s?
There was a thread here 1-2 weeks ago about the issue and pretty much EVERYBODY had this problem.
I can't find the thread anymore but it was about the delay between answering a call and the mic becoming active ... which takes 2-5 seconds.
I just noticed the other day that the delay seems to be less if I immediately put the call on speaker.

Never encountered that issue. The other side hears me immediately as I answer. I guess this is not "across all N1s", unless someone would think my N1 is special in some way (which it isn't, and so are all the other 7 N1s of my friends at work which also happen not to have this problem - and the call quality is great on at least 3 that I checked personally).

Instantly connects on my phone as well, so it's not on all devices at least. I have one of the first batches of T-Mobile N1's btw.

What carrier are you on?

this happens to me too.its so annoying. im on att

Can't find the thread but it was pretty long.

I'm not so sure anymore. I decided since my only choice was to send it in for repair, I might as well one click root and install CM6 and see what happens. So far, I have not had the issue. It's only been three days but that's the longest this device has ever gone without having the "no connect" issue. Also, my low call volume and speaker phone volume issues are now resolved. I now find myself turning the volume down rather than up. I'll update this thread with final verdict on whether this fixes my issue.

This sounds like an att problem not a nrsux one problem

I notice this problem as well. If I wait until the call timer appears on screen before I start to talk the other party doesn't seem to notice.

I'm on T MO and never had this issue. Try the one click root and flash a different ROM. If it doesn't work send it to HTC. I recently sent mine back on a Monday and it was back that Friday.

Well my issue has been resolved by switching to CM6. It's been a week now and the issue has not occurred even one time. This was an issue that used to happen to me EVERY DAY, so I am very happy that in my case it turned out to be a software issue.
When I was running 2.1 I hoped 2.2 would fix it and when it didn't I thought for sure it must be hardware. It's so nice to KNOW I can answer the phone if it rings now. Sometimes I would get an important call and I was afraid to answer the damn phone!
Thank you Mr. Cyanogen, whoever you are.

I get this issue once in a while. I think its a software issue. Over time something gets hung up somewhere.

I had a thread like this as well..
http://forum.xda-developers.com/showthread.php?t=691399
For me it still happens randomly, stock 2.1 rom, stock 2.2 rom, Enom's ROM, etc...
Although I have a theory that I haven't tried to prove/disprove yet.. It seems like several times when this has happened I was holding my finger over the second mic on the back, which is naturually where my finger seems to lay when I hold the phone. Anyone else considered this? I'm thinking maybe it's throwing off the microphone trying to do noise cancellation?

Definitely not the finger covering the mic. Just tried it with/without and same result.
There was another thread that was at least 3-4 pages of people complaining about it.

Sounds more like a network issue than a hardware issue, IMO

This issue has come up recently for me and it's really annoying. I'm not sure what triggered this problem...
Is anyone else experiencing this issue? Any ideas on how to resolve?
I've got the Rogers/AT&T N1.

[Q] issues w/ G2

My G2 may be defective or is it this buggy?
I've actually had the phone reboot on me twice. It looked like a kernel panic like i'm used to on my nexus one with cyanogenmod nightly builds. not only that but i don't see any internet speed improvements in my area over the nexus one despite my area being HSPA+ deployed. I get about the same 800kbps-1.5mbps on both phones. Others in HSPA areas report >3Mbit.
I will also have some considerable lag issues and just plain hangups with switching applications that i never experienced on my nexus. Also I only get about 1.2ish gb of internal storage while othere report >2gb.
On the upside my hinge seems fairly solid and battery life is good. but those glaring issues have me wanting to return (get $ back) and go back to my nexus.
Did I get a lemon? Are others experiencing this as well?

Uhm... this forum is full of these complaints, how could you miss them all?

Experiencing the same issues. Phone just turns itself off. Poor to no reception in areas where my Vibrant and Nexus One get2-3 bars of 3g. Like the phone but it does have issues which some people are reluctant to see. Weird things happen when I deploy the keyboard. Return button does not work at times etc.

From one entire day with the phone I thought reception was weak as well. BUT I asked my wife if her TMO BBerry 9700 had dead spots in the same areas and sure enough she said yes.
I'll be double checking that tonight.... I'll be much happier if it's the network and not the phone.

A lot of users seem to be having these so don't worry you aren't alone.
I get absolutely NO reception in my room (basement lol), coincidently I also use my phone as an alarm and couldn't figure out why it always stuck itself in a boot loop more at night than during the day (which it did...up to five times).
ANYWAY, personally I cut on airplane mode at night and have no problems with the phone crashing and boot looping (G2 splash screen). Ive also installed Rom Manager and run "fix permissions" which has basically stopped the random fc's and crashes during the day. I cant remember if the fix permissions is root dependent as ive always had root when running it but it worked very well for me. Before permission fix my phone was fast but seemed to jerk and twitch going through screens, now it doesn't.
I haven't experienced the freaky ghost track pad issue and the non responding touch screen which caused me to have to lock and unlock the screen.
These might help until either someone can achieve permaroot or tee-mobe sends an ota.

I've had the same reception issues. Tech support told me to do a factory reset, but I don't see how that would help since I just got my second phone two days ago (first one bricked after a kernel panic). It has had these problems out of the box.

[Q] Just sent HD2 back to HTC (screen issue), opinions/info?

So, I've been having the screen sensitivity issue, jaggedy drawn lines, randomly typed keys, etc.
Now, has anyone else done the same?
As the problem is intermittent, what're the odds they'll actually fix it?
Also, is it actually going to be gone 2-3 weeks or do they usually turn around quicker?
I miss it already

mine was gone for 24 days, all it needed was a software flash. overall, good service, but could be quicker......

if they just flash the software I'll not be happy, I could do that myself.

I have this issue too, and I read about it on some other threads as well.
I'm not really sure what is causing it, but its more likely to be a hardware issue rather than software.
Although my friend bought his HD2 recently, and his phone doesnt have this problem. I guess this issue is fixed in newer HD2s
You can see this thread for discussion and videos about this issue

their service is worst ive ever know...4 weeks so far....never going to send my phone to them, rather send it to dodgy kev from the pub to fix

TouchScreen issue resolved in gingerbread?

So before the gingerbread update i was experiencing the nexus one touch screen issue. This issue would happen mostly when the phone would be charging or warm, and the y coordinate of the touch screen would be off by about an inch. (I would post a link to youtube but i can't yet... new member =/ ) So if you try to answer your phone while the defect was active, you couldnt, because touching the slider would be recognized as trying to touch the 'menu' key on the phone.
Anyway, after gingerbread got pushed to my device, i have yet to experience this issue!! i havent been able to find anyone reporting this resolution. i'm extremely please about this because it was becoming a deal breaker after i missed an important call because i couldnt answer my phone due to the issue!!
anyone else experiencing this resolution!?

In my experiences it does still occur, although seemingly less frequently. It is a hardware problem though so probably won't disappear regardless of the OS

Yup. For some reason I have worse now than before. Maybe I'm just using it more now. Lately it's driving me nuts, to the point of actually looking at a replacement.

this is where I was at before the push, i was seriously considering the incredible s, but for now it seems to have completely disappeared from my device...
I've also heard its a hardware issue (I do believe it to be true, not questioning that), so i found it extremely odd that its not happening now on my device.
Guess I'll just keep my mouth shut and enjoy

Observed no difference. The bug still appears every now and then. Doesn't bother me much because it usually occurs when the phone's charging. Not when I'm on the street using it. I heard that removing any kind of screen protectors can actually solve this problem.

I had it terribly after the GB OTA, I wiped cache & dalvik and it all but went away. One occurrence in a week and a half, and I've been using the crap out of the phone.

Slightly off topic question: On stock Android, is wiping cache the same as wiping the dalvik cache? The stock recovery doesn't have the "wipe dalvik" option, only "wipe cache".

No it's not, but if you have root you can wipe it manually by removing the contents /data/dalvik-cache/

Thanks. But every time you flash an official update, the cache gets wiped and rebuilt though, right? That's why after each update it takes a long time to boot.

I still have the touchscreen issue. i think it will never be solved because it's an hardware issue, not a software one.
So the problem still appears, maybe a little less frequently.

I still have the prob but it's different with 2.3
Before 2.3, the touchscreen problem was unpredictable and could happen at almost anytime, whether charging or not. I replaced the handset but the problem persisted.
Since upgrading to GB, I've noticed a very clear pattern. If I'm charging my device and unplug it before it is fully charged, the touchscreen becomes extremely erratic to the point I must reboot the phone. If it's allowed to charge completely it's okay.
It never happens when it's is not charging.
Still annoying as hell but I've moved to Africa and having the device replaced is a real challenge. So I guess I'm stuck with until I replace it.

Still has issue
Stock, no modification at all. Today when I was rearranging icons in ADW Launcher, it seems that the screen registered click below where my finger actually was, same as the problem I saw previous to updating to 2.3.3. The phone was not hooked to a charger at the time.

Stock GRI40 here on my Nexus One...same issues that i've already had with Froyo. As it was posted before, it's a hardware issue; and the Nexus S is the new kid on Google's block, so i'm not expecting anything to improve our screens.

Theoretically, there is a chance they could fix a software workaround for the hardware problem. If the error happens in only specific circumstances, and ALWAYS happens in those circumstances, then just teach the phone to know when those circumstances are happening, and tell it what to do in those cases. However, I doubt anyone at Google is working too hard on this problem. I agree, it seems to be much less frequent than it ever was. Seems likely that they may have added a little something to help us out.

Or more likely, it could be unintentional.

So even with official OTA it's still here?
Remember me of the ''crazy'' screen problem we had before while charging,perhaps it's a hardware problem after all

This is a main reason why tomorrow i'm getting a new galaxy s.
I tried a lot of custom and stock roms, I sent my phone to HTC and they replaced hardware, but this issue still persist. And it cause me a lot of problems, especially while driving...

I also still get that glitch but not as frequently. I noticed that i didn't need to reboot the phone to fix it. All i need to do is tap the power button to shutoff the screen and then re-tap to turn it back on and it'll show the lock screen. Slide to unlock and the screen is precise once again.

The bug is still there for me also. However, I didn't seem to have it as bad as some did originally, and now I've noticed that it's happening even less frequently.

Slider unlock sometimes doesn't work with incoming call

Once in a while when trying to answer an incoming call the unlock slider won't respond. I will slide my thumb to unlock and ...nothing. When this happens the call will just go to voicemail . The workaround is to touch the power button to turn off screen , then touch it again to wake it up ,then the slider will work and I can answer the call. Sometimes this takes too long and I miss the call.
This is not a deal-breaker as it only happens 5% of the time , still it is annoying. I have tried different roms with no real difference. Anybody else have this problem? Any advice other than get a new phone under warranty?

Ditto. And I always act as you did to work around the issue, only difference is, I haven't missed a call due to this.
In any case, based on experience, the chance of this happening could be minimized (if not eliminated) by always locking the phone from the "desktop" (e.g. do not lock the phone when an app is running).
BACK STORY:
I remember this happening (more than once) when someone called me up after a train ride. And the last thing I could recall is that I have locked the phone while playing Angry Birds / Fruit Ninja / Zenonia 2, etc.
But it still sucks that it happens.

I guess my real question is , are all Nexus s doing this sporadically , even rarely , or is my phone defective?

question... are the phones plugged in to a wall charger when this happens?

Nope. Only happened to me when I under clocked the CPU with Setcpu using the powersave profile (I was just testing things out).

I'm not sure if everyone's having this, but I'm with you on this. I'm on stock but rooted 2.3.3. Experienced this since 2.3.1.
EDIT: My wife has this problem too, since 2.3.1 until 2.3.3 (not rooted).

Mine did it stock , I rooted and loaded roms to see if that would fix the problem , lessened but still there

My nexus s (i9020T) has exactly the same problem. I've also tried to flash different ROMs, including CM-7rc2 and stock 2.3.3, and the problem remains.
I tried to bind Multi-touch Visualizer 2 to long pressing home button, and found the when screen is unresponsive, it can still detect press near edges very well, but not the center. While I press at the edge and drap across the center, it keeps tracking my finger correctly. In addition, Locking and unlocking the screen can solve the problem temporally. I connect my phone with adb, and tried to "cat /dev/input/event0" The behavior confirms what I see in Multitouch Visualizor 2: the when the center of screen is unresponsive, nothing can be read from the device node.
I read the mxt224 touch screen controller doc, and it seems the chip features self-calibration, and thus I believe the "lock & unlock" will trigger the chip to tune it self in some way. I've also read the driver code of nexus s, htc incredible and moto droid x, all using the same controlling chip. Both HTC and moto would send calibrate command to the chip during resume, but sumsang does not. I guess this might be the reason, but I'm not skilled enough to port the drivers

I experienced it twice so far i think, but only have the device for a little more than 2 weeks.
I am on stock 2.3.1 currently.

Beside the lock&unlock method, I discovered a new way of getting screen back to work: rub your hands a couple of times and touch again... Anyway it seem the screen is not well calibrated.

problem seems fixed with my customized kernel
Last night, I modified the touchscreen driver and mach settings a bit on the source of netarchy's nice kernel, and compiled a kernel of my own. The screen now seems working well with my new kernel

Never have experienced this on the nscollab rom which is cm7 and kernel together stable. I suggest give it a shot

May I know how to perform the suggested steps, i have been experience twice since i bought it on 2 weeks ago

I would like to bring this issue up again (after so long) as I am still randomly experiencing this exact issue even with Ice Cream Sandwich 4.0.3 (Stock & Custom ROMs). Any fix yet?
