[Q] Can't answer calls sometimes! Really annoying!

Hello everybody,
Everything is fine with my Arc, except for the huge problem that sometimes I simply can't answer an incoming call! It happens like this: When a call is incoming, the phone starts ringing and vibrating as it usually does. However, the screen that is supposed to come up which shows you who is calling and where you can select to accept or reject the call is simply not showing up.
Has anybody experienced this before?
All I can do is slide to unlock the screen and then I'm looking at my home screen with the phone still ringing but no chance to get the call. There is nothing in the notification area or anywhere else where I could answer the call. All I can do is to wait until the ringing stops!! Really really bad behavior.
Furthermore, once the ringing has stopped, there is no information about the missed call in the call log. So I can't even call back the person who called me!
First time this happened I had "Plants vs Zombies" running so I figured the phone wasn't fast enough to switch to the incoming call. But it also happens when the phone is idling.
There seems to be no scheme behind all of this. Sometimes it happens twice in a row, sometimes only once a week.
I got my unbranded simlock free Arc in mid April with 2.3.2 and .181 firmware and applied Gingerbreak for root access. Later I upgraded via PC Companion to 2.3.3. and .145 firmware. But I lost root which I didn't like. So I downloaded the Generic World Firmware .181 and flashed it on the phone. Then used Gingerbreak again and made an OTA update to 2.3.3. and .145 firmware. Now I have root and the latest firmware.
All the while I used Titanium Backup to restore all my data, settings and apps as I don't want to reinstall all from scratch because it would take forever.
With this latest firmware, everything is fine, except for the call problem!
Please help me, what can I do?? I don't want to reflash and upgrade or whatever or lose all my data. I just want my phone to be able to handle calls as it should be!!
P.S.: I used Antek App Manager and frooze (not deleted!) some apps which where uncessesary and running in the background or at startup which speed up my startup time and free ram quite a bit. But I didn't frooze any crucial apps, at least I hope. Only stuff like Chinese keyboard and Let's Golf etc.
Also, if I would have frozen the call handling app or something, I wouldn't be able to accept calls in most cases, wouldn't I?

Think you may have answered your own question here...

could be, but on the other hand I only frooze really stupid apps which should not affect any important functions of the phone. Also, if I frooze something important related to calls, why is it working most of the time? This is what I don't get.
Here is what I frooze (most of them just took up space in the app drawer and I don't use them), maybe it helps:
- stock browser (I use Opera)
- chinese keyboard (I'm german and don't need it)
- "Downloads"
- retaildemo
- live ware manager
- fb mediadiscovery
- dlna server
- news and weather
- postcard
- SE setup wizard
- sim toolkit
- sony ericsson sync service
- playnow
- sony ericsson support
- track id
- twitter
- let's golf
- google talk
- sony ericsson sync client wizard

so is your problem solved?

Anything related to google should be left alone news and weather should be fine to freeze or delete but would leave Talk alone, and depending what data from which FW was backed up, might also be an issue.

so I defrosted Google Talk. Anything else I should defrost?
Under "Settings" and then "Running services" I sometimes stop "Timescape Legacy Plugin" or whatever it's called because it takes up RAM. Could this also be a cause but I believe it's only for the Timescape app which I seldom use.

I have the exact same problem.
It doesn't happen often but it's really annoying either way.
I barely installed anything off the market and I don't use any sort of app killers/managers.

that's strange because I thought it could be my own fault because I played around and frooze same apps. But it's "good" to know that I'm not the only one.
Do you have any hints about when it happens or when not? Can you exclude anything?
Today, I re-enabled all the froozen apps and then frooze some of them again, according to the thread here on xda. But only apps about which I was really sure.
Don't know how I could test if the error is gone. I mean, have people calling me 100 times and hope it occurs or not doesn't really sound great.

may be there is some problem in your firmware,try some other firmware of other region.................

That's the weirdest part, the only thing I used that day was Whatsapp.
The incident happened about 5 hours later, I was in a car when my phone started ringing.
I tried picking it up but.. I guess you know the rest..

I was about to buy this phone but now I'm having second thoughts.

@flamez
yesterday it happened to me again. The weird thing is, that my girlfriend said she called me three times but I heard it ringing four times! She claims she didn't call me between her second and her third call! But it definetly rang but I couldn't answer it. Also my other friends say that they didn't call me at this time. Could be someone calling who I don't know at the exact time but the chance is slim I guess.
Also whenever there is such a phantom call, there's not even a hint of it inside the missing calls log. And when this happens, nobody ever leaves a message on my mailbox. Is this the same for you? Could be the person is just lazy but I don't know.
Furthermore, it happened several times to me already and never once a person asked me later why I didn't get their call. Strange, isn't it. It almost seems like that there was no one calling at all!
Now, could it be for some unknown reason that our phones just start ringing as if there is a call but in fact there isn't one at all?! You know, the phone just running crazy and triggering the ringtone? That could be the reason why the "accept call screen" doesn't show up and there's no call log because there is now call!
I know, sounds very weird. But think about it. They could be really "ghost calls".

No, I don't think that's it..
It's happened only twice to me over a 2-3 month period and my friends have always called me back asking why I never pick up the phone.
It really just happens about once a month to me, and I can answer the second time they call me right away without any problem.

Are you guys running task killers?
{EDIT - I remember OP saying that he'd frozen a load of stuff.. Suggest that if you're getting this a lot that you un freeze all of it and see how it goes, maybe just freeze the end user apps - like Lets Golf HD at first then build up the frozen apps slowly until you get the problem..}

No, as I said before, I'm not using any sort of task killers/app managers.

Today first time i encountered same problem. I have WhatsApp running in background. No task killer, nothing else.
Though i donno how to solve this problem. But i can surely tell how to pick up call in this case.
Just press the power key, this will take phone in locked state, but the call wont be rejected.
now click the home key and you will see the answer key, now slide it, it will slide without problem

it's good news that you found a workaround! I'll try to remember it the next time it happens.
Today, I had the problem again but this time it was different. The slider or the contact picture of the person calling didn't appear, but I could see the number of the person who is calling in the notification bar (not the name, just the number although this number and contact is stored in my contacts).
This happened the first time, all the other times the phone just rang without any hint of who is calling.
It would be nice if we were able to pinpoint a certain event which causes this odd behavior but so far I had no luck. What I'm doing differently since the last time it happened is, that I don't use task killers anymore. But still, it happened again today.
It's difficult to find out what it is when you don't know what causes it and when it will happen. For example, it happened to me today once for the first time in about a week.

in recent days, "it" happened very often to me!
Sometimes, the phone manages to at least show the number of the person calling so that I can call back. But usually it doesn't! The call just disappears into nirvana.
Do you guys remember if the error is associated with a certain amount of RAM left available? In other words, if the available RAM at the time of the incoming call is below a certain limit (which I don't know) the phone can't display the call. When it happened to me today, I had only 90MB RAM left. Maybe the phone can't free up enough RAM fast enough?!
Also the trick, which somebody mentioned a few posts above me, that when it happens you press the power button and then home and then you can slide and accept the call very rarely works!
I'm desperate and don't know what to do about it. I have just finished adjusting my phone to my needs. I linked apps with Link2SD and now have over 100 apps installed and still 215MB left on the internal memory, I have root and the .145 firmware. Everything is fine, except for this error!! It would take ages to restore it to the point where it is now, if it is complety possible at all.
I mean, if a phone can't handle calls, what good is it for?
I had a NEC e616 years ago which frooze while sending SMS or crashed after connecting a call or during a call and other "funny" things, but this was well known for this model.
But we don't have 2004 anymore and I except the Arc to work.
I could send it in on warranty, possibly. But then everything would be erased and it would take forever to get it repaired.
And I'm afraid they are going to tell me that they couldn't reproduce the error (because it happens so randomly)!
Such a nice and beautiful phone if not for this stupid error!
I'm already tempted to get rid of the phone and look for something else. But who's going to buy a phone with a bug which can't display phone calls?!!
I mean, I could reset it and flash the fimware and stuff and then hope. Maybe the error is gone. Maybe it persists and then all my data is gone and I have to start from scratch.
Or it is gone and then I have to start from scratch also!
If I should be forced to do it all over again and have all the work, then I could do it on another phone as well.
The Samsung Galaxy SII is quite ugly, to wide and big but I hope it can at least handle a call?!
Thank you for any help!!

Hmm..
If it happens rarely.. Why don't you sell it off on ebay
If asked about other mobile. I prefer sensation to sgs2. Much better phone function. In fact IMO htc is better than all other androids when it comes to phone functions.

Note 4 Suddenly Having a Multitude of problems. Hardware Issue?

Hello, I have had my Note 4 for quite some time now and have not had any issues with it up until the last month or so.
At first it started out as just a hiccup every now and then, an example would be when I play music via bluetooth to my Jeep CD Player, I would sometimes have to turn bluetooth off then back on to get it to connect or reconnect.
Now things are getting out of hand. Here is a list of problems I have on a daily/hourly basis and seemingly at random times. I cannot reproduce any of these problems (except the NFC problem) on demand.
I have noticed that rebooting the phone will clear up these issues (except NFC) for a short time, SOMETIMES. Other times a reboot does nothing to help the situation.
Keyboard Lag
Sometimes when I press the keys the phone vibrates indicating a key press and magnifies the key that is being pressed, but fails to enter anything in the text box/input field. For the record I am using Swiftkey. I have noticed that this happens most often when I open an app via "popup notification." For example, if I were to receive an IM or SMS I would tap on the notification that pops up, which then switches to/opens the corresponding app. It is then I will more often than not have this issue. To remedy this I have to close and re-open the app, sometimes several times causing the keyboard to open and close, several times... Sometimes when I TAP a key, the phone will behave as though I have held the key down or performed a "long press." This issue is not exclusive to the keyboard, it often happens anywhere on the screen and with any app, usually indicating that I have been "long pressing" for about 1-2sec at a time.
NFC Does Not Work
One day while I was at work I attempted to add the office printer via NFC. To my surprise I was unable to turn on NFC via the "quick settings" drawer. In the quick settings panel the NFC icon would light up, as if it were turning on, and then just turn right back off again, this happens consistently. I went into setting to enable NFC that way and I am stuck with a slider that is actually in the "on" position but greyed out, I am unable to interact with it.
Bluetooth Connectivity
I have a JVC CD player in my Jeep, I often use YouTube or Google Play Music when I drive. Usually I do not have any problems connecting to the CD player at first, but after about 30-60sec of playback the audio goes blank. The app says that it is still playing however no audio can be heard. Then it will suddenly come back on after about 5-10sec, and here is where it gets strange. After the audio comes back on after this "hiccup" the playback is fast, as in it is playing at 2X's it's normal speed, makes the vocals sound like chipmunks. This will continue indefinitely until I turn on the screen, unlock the phone, then shut the screen off. Then the audio goes on playing fine. This happens with both YouTube and Play Music, while using YouTube the video gets sped up as well. I also experience issues with connectivity where sometimes at random the phone will just disconnect from the CD player, and refuse to reconnect until I have rebooted the phone, or if it does reconnect I get no audio until the phone is rebooted. I notice that this ONLY happens when connected via bluetooth. If I turn bluetooth off while this is happening music will play over the phone's speaker perfectly normal. My CD player has a hands free feature, and I do not seem to have any issues with phone calls, it's only with music playback do I have problems.
Originally I thought it was my CD player acting up, however in light of the other problems, and the fact that I tested it with my tablet and two of my friend's phones without issue, I don't think the CD player is the problem.
Sluggish/Glitchy UI
Sometimes when the phone really freaks out, the UI behaves very strangely. Sometimes notification Icons will hover above the running app, other times the whole screen will lock in place for a few seconds. Sometimes if the screen is locked up, I will shut it off, then turn it on, shut it off, turn it on. However as I press the power button to turn the screen on and off, nothing is happening, the screen just stays black while the "back" and "recent apps" buttons light up at the bottom. Then when the screen does finally come back in it will flash on and off quickly in accordance with how many times I pressed the power button. While all this is happening, if I hold the power button to turn the phone off, the power/reboot menu will appear without incident. Sometimes when I am swiping to unlock the phone, it does not register the full swipe. Basically it acts/appears as though I lightly touched the screen and moved my finger a half inch even though I have drug my finger all the way across the screen. To remedy that issue I have to SLOWLY drag my finger across the screen and then it unlocks without incident. I have also noticed that when I go to "swipe away" a notification, especially one that has "information" in it, it will swipe off the information but leave the notification there and display the app name the notification was from. An example would be, if I just installed an app (for example YouTube) from the Play Store, the notification will say "YouTube has been successfully installed." When I swipe either left or right to remove that notification, a "white ghost box" or "overlaying top layer" with the "successfully installed" text in it will slide away. However it leaves behind a green box/notification that says "Google Play Store" and that remains until I shut the screen off and turn it back on.
NFC Will Not Turn On
I simply cannot get NFC to turn on, the slider is in the ON position but is greyed out as I mentioned earlier. I would post a picture but I guess there is a 10post rule before I can do that. I have given up on NFC, mostly because I rarely use it, so it's really not that big of a deal.
Initializing the Camera
I use an app called "Telegram" instead of SMS messaging, thus I use Telegram to share pictures with friends. Sometimes, again I am not able to reproduce this problem on demand, the problem comes and goes seemingly at random. The camera will take more than 30-60sec to initialize, while I am waiting for it I am stuck with a black screen. If the camera doesn't initialize, shutting the screen on then off will take me back to the telegram app. I never get an error message or anything. Other times when I try to use the camera it pops on instantly and works flawlessly. Originally I thought this was a problem specific to telegram, however in the name of science I tested it with the default camera app and get the same results.
USB File Transfers
I'm not really sure this is specific to my phone, but whenever I transfer files from my PC to the phone or from the phone to PC, it is PAINFULLY slow. It's even painfully slow when the PC just displays what is in the folder. However I can't say for sure this is related because I never attempted to transfer files until I started having these issues, at which point I thought it would be a good idea to start backing things up.
Gets Stuck in 3G Mode
This happens rarely, not even sure that it's related but I felt that it was worth mention.
What have I done to try to remedy this problem you ask?
So far I have performed a non-root ADB nandroid backup, just in case factory resetting the phone didn't work.
I have factory reset the phone 2 times, I see no improvements.
I have cleared out my SD card/removed SD card
I removed and/or shut off bloatware apps (Yes I tested the phone without removing/disabling bloatware, still having the same issues)
Wiped cache via Recovery
I am not sure what else I can really do to fix the phone, I am starting to think that this is a hardware issue. I should mention that there was no significant event that I feel would cause these malfunctions. System update installed and worked perfectly up until this last month, I have not dropped the phone from significant height, the phone has an otterbox anyway. I have not gotten the phone wet, it has not been left outside, this phone has not seen any abuse what-so-ever. I just started having these problems out of the blue and they seem to be getting progressively more frequent and longer lasting. If I don't get any ideas from here I am going to try to get Verizon to replace the phone via insurance, however I don't have high hopes for that because I have grandfathered unlimited data and this is not the "original" phone that I had when I added the insurance option, so I am not sure it's covered.
Does anyone have any ideas on what could be causing this or anything I can do to correct it or try to troubleshoot it?
Any help is greatly appreciated!

I realize that this is a long post but whenever I ask for help I like to be detailed. If I left out any information that might be helpful please let me know.

Unfortunately, it looks very much like components on your logic board are going bad. Sometimes a few specific things will go bad that don't actually make the phone unusable, but make it act similar to what you are explaining. It wouldn't be worth the money you'd have to pay someone to track down the bad components and replace them. If you really like the note 4, I would just make a full backup with kies while you can, buy a new phone and restore your backup.

All of Kies backups do NOT restore to a new phone! Only contacts, messages and call logs will restore on a new phone. Use Samsung Smart Switch or Helium. Good luck

I see. I didn't know that because I've always restored my backups to the same phone. Thanks for the info.

My LG G3 keeps on rebooting...

I have a problem with my phone today.
Actually last days my phone was quite slow so i disable some applications like google music, google movies etc... that i was not using at all...
It seems however that this affects the system files as since I have unistall the google music i got an error like "the system service is not responding". Initially i ignore it but now I cannot start my phone.
I start my phone, boots in my phone, stays on a black screen(showing only the time at the top right corner and the navigation buttons at the bottom) and then restart by itself.
I never had a backup of my phone...
I don't care about my contacts as most of the are saved in my google account however I want to save my text messages.
Is there a way to manage to start my phone without re-installing the system or wothout loosing my data?
I am really new to this so any instructions to be follow should be for dummies
Thanks for any help in advance.

Text messages / notifications not coming through

Hi!
First of all, I'm new to this phone - I owned it for about 2 weeks. and I'm very happy with it. Nonetheless I have noticed an issue that I hope someone can help me out with:
Since the phone doesn't have the notification LED, I have tried out a couple of apps to facilitate this function. I ended up uninstalling them. Now I experience that some notifications are not coming through (so far I've noticed text messages). I'm trying to figure out whether this is an issue with the phone, or if it might have something to do with the notification apps that I tested? I configured the apps and settings/permissions as necessary to get them to work, but I never reset those same settings before I uninstalled.
The issue I am facing is e.g. if a text message is sent to my phone (with display not on), the text and/or notification randomly doesn't get through until I wake the phone. After waking it, the message comes through immediately. Could this have something to do with testing those notification apps? If so, is there any way to find the specific settings and reset them or am I facing a factory reset to get it to work properly again?
Any help or hint is appreciated

Question Pixel 6 Pro won't stop playing notification tone during calls

My Pixel 6 Pro has a similar problem ever since the Mar 5 update has been installed. Since then, every phone call I made comes with the non-stop notification tone literally every second. For now, I managed to get around it by enabling the "DND Mode", but it isn't a long-term solution.
Is there a way I can re-apply the same update? or flashing a new one would help?

To be clear, you're saying that you keep getting the notification tone even after answering the call? If so, is it the same as your ringtone?
Is your bootloader unlockable? If so, Official Google Android Flash Tool (OEM Unlocking needs to be toggled on - you may not have to manually unlock the bootloader - the "site" will do that on its own).
It wouldn't surprise me if that doesn't fix the issue, however. Have you tried rebooting? Maybe clear the cache and app data for the Phone app (but then you'd have to re-customize the settings for the phone app to your preferences).
I'm not on the March update, but I also don't receive many phone calls anyway.

that notification tone, during normal time, represents incoming message. It is very short, unlike a ringtone..
Tried rebooting and clearing cache and app data of the Phone app. In fact, that notification could likely come from anything like WhatsApp, Messenger, Twitter...
I noticed that the repeating tones would not happen if the phone is on silent mode. So for now this is my workaround.

Very interesting, and strange. There have been settings in some OEM's phone apps you could enable to get notification tones at regular paces - usually once a minute - while on a phone call, but the issue on yours is only similar since it's constant / every second.
I stick with my recommendation of clearing the app cache and data for the Phone app. I also assume you're using the stock Phone app that Google provides.

In my previous phone (OnePlus 6T), the very same tone happens once in a while, but only at the moment an incoming message arrives. Pretty sure I am not getting a new message every second this time around, and I think it was triggered by apps other than the Phone app. I just noticed that the same symptom showed up when I tried to play video clips from certain apps as well.
And yes, I am using the stock Phone app.

Sounds like a factory reset and only selectively installing and configuring apps, or trying to figure out which app is causing the issue.
If you factory reset, I would first not even restore any apps at all, so you can verify if you have the same problem without any third-party apps installed at first. I would suspect you won't have issues then. And then when you install apps, do it in groups of your most important ones first, maybe at the most 10 at a time, then re-verify each time if you have the same issue or not, then the next batch of app installs. It could be a particular setting in a app as well, so it's possibly merely installing an app might not be enough, so each group of apps you install, make sure and configure them as well.
If you don't factory reset, go the opposite way, uninstall your least important third-party apps and see if the issue disappears. Keep track of which apps you're uninstalling in each group. Keep doing this in reasonably sized groups of apps until you narrow down when the problem stops happening.
Once you find which group of apps being uninstalled keeps the issue from happening, you can reinstall in even smaller batches, among the ones you most recently uninstalled, and eventually find the one causing the issue. In some ways I think it's easier to go the other way around, though, start with a factory reset.

Found the culprit!
Kind of silly: I have installed this app "Internet Speed Meter Lite" when I first started using my P6P, which is for me to monitor my real-time network usage (courtesy of that endless WhatsApp - Google Drive restoring process....). It basically refreshes itself every second and this morning I tried temporarily disabling it, the problem goes away even when the phone is not set to silent mode.
Glad I didn't have to come to the point of factory resetting the device, as I really don't want to go through the WhatsApp restoring process.
Thanks for all the input, much appreciated.
