Major problems with dropping calls!

First off, let me say that having been a WinMob guy for the past 4 years, this phone has been a revelation in good design. I love it.
The ONLY thing that is impacting my experience with this handset is its CONSTANT habit of dropping calls! This usually happens completely at random, sometimes 1 minute into a call, sometimes 10 minutes into one - happens with both poor service and full bar service.
Could it have anything to do with HSDPA being active during voice calls?? Haven't had this issue with any other phones before and I certainly don't want to have to return it for a fix.
Any help with this would be very greatly appreciated!!

I've experience it a few times, put it down to poor T-Mobile coverage so far.

Happens every call with me, really can't figure out what I can do to fix it. Just hope it's not a hardware fault.

Has any one had any similar experiences with their handsets? Or alternatively, any ideas on how to fix the issue?
Thanks, just want to know so I can decide whether to take it back or not...

Guys, any help with this?

Well, I've never had this problem until today when I dropped a call twice. Had full bars. Hmmm. (T-mobile in case it's a network prob btw)

Have you had a look on the T-Mo Android forum ?

I've not looked there for sometime now.

I've been using it in Switzerland for a week, and have had no dropped calls whatsoever, so i'm assuming it's something to do with T Mobile UK

(Just for the benefit of any one else who will read this, I'm on O2.)
Hey guys, might have found a fix for this -
1. Turn phone off
2. Remove SIM + battery
3. Put battery back in without SIM, turn handset on and leave for 3 or so mins.
4. Turn off, + put SIM back in w/ battery as well
5. Change Network data setting to receive WCDMA only
Seems to have worked, but haven't tested extensively.
Btw, thanks for the t-mobile forums link, did help.

ive also had the same issue. had the same problem on my hero on 3 before I got my desire which is now on Orange and still the dame problem. also g1 on 3 had same problem. must be a problem on Android or with data and voice at same time.

I thinks it's more the phone since I'm AT&T with a Telus Desire.
This happens to me too with 2-4 bars. I thought it was my cheek hitting the End Call but it happens with BT too.
Maybe I've just been spoiled with Nokia and Motorola's reception...

It happened in Taiwan before. It's sim card's fault. We replaced our cards with new ones and problems are solved.

Hearing caller before answering?

Ok this was a blast from the past for me last night, I remember this happening on my Mogul. My evo was lying on the counter charging, the phone rang and while it was still ringing I could clearly hear the person calling talking to someone else with them before I even picked up the phone to answer it.

Does it still count against your minutes if you don't answer the phone?

I was thinking about if this was possible a couple weeks ago, I don't see why it wouldn't be, just have to activate their mic when they call.

This happened all the time on my touch pro 2 with energy rom glad no one was talking crap before I picked up.

That's actually kind of cool - I wonder if someone can build an app that would do this intentionally.

It's not actually that cool. This happens to me. It's quite annoying when the phone is on silent or vibrate and I'm in a meeting at work and get a call and all of a sudden you can hear people talking. Not good.
I've narrowed this down in my case to it being an issue with receiving calls from the AT&T mobile network. All the calls I've received that do this are from AT&T users or Net 10 users (which are using the AT&T network). No issues with calls from other Sprint users, Verizon, etc. As of now, Sprint hasn't been able to offer a fix.
Anyone else had this problem? Any resolution?
Oh, and I have an Evo. Bought it on launch day from Radio Shack.

I have this problem too, I guess I have to send the phone to RMA. Tried with different ROMS (official), still the same.
Well, I have flashed the 3.14 ROM official WWE and seems the problem is gone now. Check it please and reply .

[Q] HTC Desire Z - Serious Call Issue

Hi Guys,
First off, I am using the Desire Z unlocked on Telus. I do not have my phone rooted, nor unbranded. It is completely stock (Bell Branded) only modification was the unlock via unlock code. The phone is running 1.34.666.5 software, and kernel 2.6.32.21 if that helps anyone. I purchased via a friend, who gave me the original purchase receipt (for warranty purposes). However he has since left for Kingston now that the holidays are over.
The problem I am experiencing is via my calls. About 75% of my calls experience random mutes, where the other person can hear me, but I hear just silence. Sometimes it will happen soon after a call, sometimes 20 minutes into a call, completely random timing and duration. Most of the times, the other person will hang up thinking it is their phone and call me back again, only to have the same problem again...
It gets worse though. About 25% of the time, people on the other end have told me via text, since they can't hear me, that my sound is coming very scrambled. Like an alien frequency jumbled up. I can't explain the sound but I've heard it and it sounds really weird. Obviously, they hang up, and call back but the same sound remains.
My only temporary solution to these problems is to restart my phone. I don't know how long I will be able to talk on the phone again before one of these two problems hit me again, at which point I have to do another reset.
I find myself resetting the phone about 5 times a day.
My hope is that this is a software issue, and that an update will fix this scrambing/muting out problem. I wanted to know if anyone else had any sort of issue with this, or what I can do to resolve this.
Any input would be appreciated. Thanks.

Maybe it is a network issue?
Try making calls from a friends SIM card.
What provider are you with?
Maybe try popping your SIM into another phone and trying that too...
If not you'll need to try to get a new phone.

I am with Telus as my Carrier.
I will try the sim in another phone. I would hate to have to return it without the original purchaser being present - I imagine not being a Bell customer (even though I have the original reciept) would make it more tricky.

I *really* doubt that it is a hardware problem.
In fact, I've heard those kinds of noises from other phones (i.e. RIM) calling me from the belus network (I use globalive... much better.)
Possibly a radio update might improve compatibility, could also be sim related.
I suggest that you root the thing, upgrade to the latest radio firmware, and install either tmo-ota or cm-mod on it. Also try using it on a DIFFERENT network (it is also compatible with robbers, but not globalive) and try using it on the SAME network with a different sim card.

Bell and Telus' new WCDMA network stinks. It is super weak as for now they put up the minimum towers to get full coverage. What that means is anything to anything will interfere with the signal strength. If I had my choice I would go back to Rogers in a heartbeat.
You issues sound exactly like a loss of signal issue.

My wife has a bell desire z and it had the same problem. Should I return for a new one?

Just one more thing. If it is a network related issue (bell). Why does my Samsung Galaxy S on the same network not have this issue? I think it is hardware related.

I have experienced the identical issue a few times and I discovered it happens when you are on a call and the phone either switches to or tries to connect to a wireless network. My specific incidents have always been with a bluetooth connected however. Try turning off the wifi........

That is interesting because her wifi is on when it happens.

I've just had the same problem... I've had the phone for around 26 days now and this is the first time this problem has happened. Anyone else solve it yet? I haven't even switched on the wifi.

Desire call issue
Hey guys,
Having the same issue, this is my second desire for the same scrambled issue. it sucks. sounds like a transformer is in phone.

I'm leaning toward that it's a carrier issue, not a hardware issue. Seeing how there are several people posting they have tried it on different phones and still had the issue, it would show that the hardware is identical between the devices. Also, seeing how people are having issues are localized to the one carrier, that would also make a difference.
I would like to state that I think rooting the phone and flashing a new radio update may fix the issue. If it doesn't, it could be that the radio in the phone just isn't built to process the network. But since it can physically pick up the signal, it may be how the software is transferring it, which is why you're having the issue, which is why I am recommending a root/radio fix.
In regards to the Samsung Galaxy S being brought up, it's different hardware, different software. Though it runs on the Android OS, Samsung uses it's own hardware and scripting, so it may be built to handle the connection better. It's the reason why for the longest time they were having GPS issues and we weren't (at least for the Vibrant variation of the phone).
That's just my humble opinion from my own dealings with phones though

Can confirm it happens when wifi is off.
Sent from my GT-I9000M using XDA App

I have had it happen 4 or 5 times and I have owned the phone for 5 months. Twice BT was connected as well. It has only rarely occurred for me...

My room mate is having the Same issue, stock Bell Desire Z on Bell network. The only two ways I have found so far to fix the issue is ether re-boot the phone or put it into airplane mode and then out of airplane mode. Doing a power off and then back on does NOT fix the problem (using fastboot), i'm sure it would fix it with the fastboot feature turned off.
Turning the radio on and off again fixes the issue so I am guessing it is a software issue. The Desire Z is an upgrade from an iPhone 3GS using the same SIM card on the same account, the iPhone never had the issue over the period of 1 full year.

Same Problem...
Hi everyone,
I wish there were a simple solution to this problem. My phone is doing the same thing (unlocked on the Telus network). I've researched this issue and found out that many people have also had the problem with the alien gurgling noise regardless of which network they're on.
I've had this problem occur regardless of wifi being on or off. It has nothing to do with the type of phone you're calling (as one Bell rep suggested). The problem is with receiving and dialing out calls. I've had several different types of phones while on this network and have never had this problem before. As for letting the problem sort itself out on it's own over time, that also doesn't work.
I brought my phone into Bell to be looked at. They thought the problem was the speaker. So they changed it and returned the phone to me. The first day I turned it on and activated it, the problem was back and worse than before. Couldn't make a successful phone call all day. So now it's back in the shop...again! The Bell rep said he's heard of this problem quite a few times. Something like 1 in 10 Desire Z's has this problem (that number sounds quite high to me). But yet, it doesn't look like these guys have a fix for the issue.
I love my Desire Z but I'm more than fed up because it's practically useless. I'm stuck using my iPhone again (not crazy about it at all) while I hunt for a replacement phone that will be comparable to the Desire Z (that will also work on the Telus network). Any ideas or suggestions? I was considering the Motorola Droid 2 Global but it didn't stand up to the Desire in speed/keyboard feel.
Thanks for listening!
P.S. - My phone was never rooted. Just unlocked.

Your all holding it wrong D: . Jk but I havnt had this issue but my gf tells me that it happens to her

calling issues

Hi, I'm looking for some help here with an issue my wife and I both have with our phones. My wife and I are the Proud owners of the Samsung Galaxy S2 phones UNROOTED. I have the Data plan and she does not. In the past 2 months or maybe since the begining of Sept. we both are haiving the same thing happen. When making or receiving calls (both in Wifi and T-mobile networks) we can't hear the person on the other end. We have to hang up and call them back (with success) on the cell or house phone. They let us know, they can hear us fine but we can't hear them.
This happens on all Landlines and Cell lines that we call or get call to our cell. I have contacted T-Mobile and they can't find anything on their end. I have done a Factory Reset on Mine and it still happens.
2 weeks ago, some weird things were happening to both our phones on the same day. with this being one of them. I plugged my phone into Samsung Kies and there was a Device Firmware update. So I updated to the ANDROID VERSION: 4.0.4 BASEBAND: T989UVLH1, and after update, I Reset phone to Factory Reset Settings and that seemed to help with alot of the freezing we had. But the phone call issues still happen.
I also have noticed, that now we periodically loose the Network connection. I can be sitting on the couch with a 100% Wifi coverage and not move an inch. I would dop my connection and the call and still have wifi coverage.I will also contact Samsung to see if it has something to do with any patches or updates. But for now, I am lost for ideas.
I was wondering if anyone else is having a similar issue or the same issue..or id anyone has a fix for this?

If it's happening to your landlines too, it's definitely an issue with T-Mobile and not your phones. You either got a noob customer service rep or a tech that didn't know what he/she was talking about. I would call again and speak with a technician, they should, at the very least, reset your service!

Thanks for your reply!
I have, since that post, gotten a new SIM card and although I only made and received a few calls, all of them were a success so far.But it is still too early to tell as this issue happens randomly. It also has been pointed out that there are others that have this similar issue and they are blaming it on the software. Which can be found here: http://androidforums.com/samsung-ga...hen-dialing-out-sometimes-not-connecting.html
I am hoping that is was my SIM card. But if it's not, and it does have to do with something with the OS Firmware version, I might consider Reverting backwards to the original ROM of SGH-T989_TMB_T989UVLDE 2.3.6. But for now, I will continue to test this SIM card out...
I'll keep you posted!

S9 Dropping calls

I have 2 Samsung S9's delivered to my company. When making calls, both phone users have reported that calls drop for 3-4 seconds and then return. This is happening on almost every call and sometimes, multiple times within a call.
The users are not moving around when making a call. They were both making successful calls with the same network (Vodafone UK) in same location on S8 phones the day before. They have independently both reported the call drop issue with the same symptons.
Anyone else experiencing this?
19th March - Tried a new Vodafone SIM but this did not fix the problem. Call dropped for 3-4 seconds, 3 times in a 10 minute call.

Yes! On both LTE/3g and wifi calling.
Unbranded phone direct from Samsung on Ee and Giffgaff (dual sim).
Hopefully next software update will fix

I have the same issue on voda UK. Actually emailed Samsung tonight requesting exchange or refund as I had not heard of anyone else with same issue
I have dual sim model but second sim is disabled as I only enable it in low coverage areas

Same here in Portugal. (Meo)

Atleast I'm not alone which says it's probably software issue hope they fix it soon

I decided to return the peice of crap and get a refund
Support offered to let me return it for a replacement but this could take upto 28 days
I'd rather purchase something else

S9 and s9+ forums here.. I think android central and some other forums
I personally thinks its a software issue but I only kept the phone for a week

I used this site https://sndeep.info/en (select Samsung) and input the serial #'s on the back of the 2 x S9's with "call dropping / calls intermittently silent" issue - they were both Made in: Korea Year: 2018 Month: February

I've also had the same issue and I spend a lot of time on the phone. Having gone through the troublehsooting and ordering a new sim I still had the problem. A new software update was released yesterday, which I have installed. I've had severall calls since and so far no problems to report.

I am on Optus network in Australia and I have installed the latest update ARD1 available on my phone. I am still facing the issue and happens multiple number of times during a call. It happens during important conversations with clients and I miss bits and parts of the conversation which annoys everyone. Today it caused me huge loss as well. Samsung should be sued over and over for this. Has anyone found a solution? Kindly help. Thanks.

I am using Amysim.

Thanks. I had the same problem with AldiMobile SIM (Telstra network) in my S9. Most of the cheap SIM providers in AU's are relegated to a subset of the better networks and had the S9 silence issue but after 8 weeks of intermittent silences, I moved to 100% Telstra SMS which fixed the issue for me without doing any firmware upgrades tho apparently the latest S9 firmware upgrade is supposed to have fixed the "intermittent silence" issue on all those cheap SIM providers services in Aus.... but I haven't had the patience to check.
