HD2 phones missing calls and hanging up mid-call

Hi all,
I work in a company who have just dished out over 100 HD2 phones to their staff... we're on call and are having some problems with the handsets missing calls and dropping calls mid-call, and I just want to know if we're alone in this, or if it's a common problem, or better, if anyone knows of a solution!
We use Orange (UK) as our carrier, the phones are NOT orange branded....
When we get a missed call, we can be in an area with good coverage (3G or otherwise, it doesn't seem to matter). The person calling us gets a ringing tone as normal, but the phone doesn't seem to do anything (ie, no indication that it's getting a call coming in). Once the caller has given up (or been directed to answerphone) we do seem to get a message telling us that we've had a missed call, but this is a text message, not a windows mobile message, and can be upto 4 hours later!
We've also had situations where an HD2 has rung and we've picked it up after one ring to be informed that the caller was about to hang up as it'd been ringing at their end for over a minute!
The other issue we have is with the phones dropping calls mid-call both when taking or making a call... The phone handset shows good signal even when it drops the call... At first we thought it was people touching the hangup button on the screen with their cheek, but I've now witnessed the phones do this when held away from the caller's face and even when it's been on speaker phone waaaaayyyyy away from anything that could touch the screen or buttons...
Oh, and we're running software version 1.66.405.2 on all of the phones, and it appears that the problems are occurring on many (if not all) of the phones... They're all running BsB Tweaks and have all been setup in exactly the same way...
Anybody got any ideas? They seem to be a lovely device for everything else, it just seems that the actual telephone side seems a bit flakey...

lol... every problem you just described was happening to our company when we were using the Orange network in the UK.
We left Orange exactly one year ago after almost going legal with them due to their extremely shoddy service plus underhand and downright illegal activities with our account.
To cut a long story short...
When we took out our contract we bought every line as sim only and Orange gave us a hardware fund to buy our handsets as and when we needed them.
Turns out though... every time we bought an offline handset they were putting it through as an upgrade! This obviously increased the length of contract for the each connection in every purchase. The very definition of an upgrade in Orange's own terms of service (at that time, they may have changed it now) did NOT include buying a handset for a SIM only connection.
On top of this we had the exact same network/service problems you describe with ALL of our handsets (including the non winmo ones), plus many other other issues with their network/service.... missed calls not actually ringing the device.... text messages delivered late and voicemail notifications sometimes up to 6 days late. Dont even get me started on the dropped calls.
When it came down to the month we were supposed to be out of contract Orange told us that we were still in contract and we owed them £70,000 plus the full price of all of our handsets if we wanted to leave!!!!
Well... we told them they were talking rubbish and after a lengthy process going back and fourth with their legal department they eventually admitted defeat. They didnt have a leg to stand on really so Orange didnt get a penny and we kept all of our hardware.
Apologies for the lengthy post there i was trying to keep it short and keep my post in context. What i am trying to say is...
In my opinion your issues are more than likely down to the Orange network then anything else... but they will REFUSE to admit a problem. They also will not support your handset if you didnt buy it directly from them.

Having the exact same problem here so it can't be a carrier problem. This issue goes hand in hand with the switching of bands problem reported in another thread. The only solution as of right now seems to be turning off 3G network-capabilities completely until we get a radio that functions as it should. Would you mind contacting HTC? I think that a company threatening to sell their devices due to bad support on their part might make them do something about it. Us regular consumers they just ignore.

imo... its definately a network issue....Which carrier are you using?
i have HD2's on Vodafone and T-Mobile (both UK) and do not have any of the issues i had previously with Orange (didnt have HD2's at that time though so maybe its just unbranded HD2's on Orange?)

The same carrier I used on my Touch HD and had no problems with(Saunalahti). Going to try the new 2.09 radio and see if that solves my issues.

Which country?
It would be helpful to actually post some details!
Like i said above... it could be the HD2 on your particular network that has an issue.
I really dont think its a handset problem as if it was literally everyone with an HD2 would be going legal!
Ive been using HD2's since Novemeber 2009 and havent encountered any of the problems described in this thread.

My HD2 is switching networks and dropping calls whenever it feels like it. Currently using HSDPA only with GSM + UMTS. I'm guessing my problem is more related to the switching of bands than anything else. Why it would loose its connection from one second to the next is beyond me, but this is a known problem.

Thats a slightly different issue to the OP. Your problem does indeed sound like it is down to band switching. There are a few threads on these forums about this as you already know.

I know, but I think the underlying problem is still the same - I've had plenty of calls dropped even when having full bars. Could be a carrier problem, but due to the amount of people having similar issues I'd say it's a hardware/software problem.

with the band switching issue im unsure... i dont have the problem on any HD2 so i cant possibly comment what the cause could be.
But the OP in this thread has other issues unrelated to to the band switching problem... voicemail notifications delivered late... calls being missed due to phone not even ringing etc... these are NOT related to dropped calls caused by band switching. Im 99.99% sure they are network problems having seen the exact same issues on the exact same network myself.

You're probably right and as a user of the same network you probably know better than I. Was just trying to be helpful.

Maybe he has both problems? shoddy network service AND the band switching issue?
who knows as he hasnt posted back?!

What's interesting though is that we've previously had HTC Touch Diamond 2s, Touch Pros, iPhones (although only a couple) and standard Nokia boggo handsets with the same provider (Orange UK) with no problems.... It's only the HD2s that seem to be affected by these problems...
I'm not sure if it's a band switching issue... is this where it drops from 3G to GSM (or the HDthingy half way between!)? I have noticed the phone drop from full 3G to the H symbol at times for no apparent reason...

er... you do know that H is faster then 3G right?
Its goes like this: HSPA>3G>GPRS>No data/only GSM
I assumed that you knew this if you were supposed to be supporting mobiles for your company.
If you have only 1 bar of HSDPA/HSUPA it is still faster then 4 bars of 3G.
Also... i sort of got at this in a previous post but the Orange network does not like it if you use handsets on their network that are not bought directly from Orange themselves. Your story is oh so familiar to me.
What i would suggest you try with one or two handsets is flashing them with an official Orange ROM for HD2. This firmware must be floating about somewhere as i do believe Orange have the HD2 on their books.

I don't support the phones, I just set 'em up and give 'em out... I'm a broadcast engineer who supports IT and Radio broadcast studios, not mobile telephones... as I said in my original post, I am on call with an HD2, which is a company phone and is dropping/missing calls... I just came on here to see if it's a known problem with HD2s, and if there's a solution, or if it's likely to be something with the network (Orange) which we may be able to jump up and down about and get them to resolve...
I had remembered it the wrong way around with HSPA and 3G, so thank you for clearing that up for me...
Is the band switching issue when it swaps between each then?

nobody else got any ideas?

*tumbleweed passes....*

I'm having similar issues on AT&T in the US. My callers get a fast busy after my phone rings a couple of times. It does not forward to voicemail. I have to force the phone to GSM then call the person back. UNACCEPTABLE.
Sometimes they get "all circuits are busy" message too.
Did you ever geta solution? My 3 year old x7500 is a better phone than this HD2 is at this point.

They probably won't tell you what equipment they have in your area (due to security reasons) but if they have Motorola based cellsites, then you're going to get these issues as the radio equipment struggles to pass from GSM to 3G and back again.

You are not alone........
I don't think this problem is necessarily restricted to Orange; my company had the same problem when rolling out un-branded Touch Pro devices to our users....and we're on the O2 network in the UK.
Our users experienced exactly the same symptoms - calls dropping, unable to answer calls before the other end hung up, etc...
It wasn't until we installed a ROM update from HTC on all the handsets that the problems....um, lessened...they got better but were still present at a much lower level than before.
I think that one poster has already suggested trying a different radio (i.e. the bit that actually handles the calls/band switching etc.), which is separate to the software (version 1.66.xxx in your case). There may be an HTC ROM update on their site - these usually include software and radio updates in one. You can find your current radio version by going to Settings | About Phone | Software Information - it's listed as "Radio Version" (and the latest is somewhere around 2.10.xxx - taken from a T-Mobile US HD2 I think).
When networks brand the HTC handsets, they also test the various radio ROM's on their networks, before loading a (suitably bloated) software ROM and known-working radio ROM onto the devices before shipping. This, in most cases, is something you can try loading on your unbranded devices - not so here, since Orange never released the HD2 in the UK (ok, don't shoot me - they did release it in very small quantities on their business tariff before pulling it due to "issues found in testing"), so they sure as **** didn't release an updated ROM for the device.
Your best bet, if you can't find an HTC ROM update later than 1.66 (which I don't think there is...yet), is to get involved with this forum in the Leo section. Learn about flashing a new HSPL and then try some other radio ROMs to see if any of them solve your particular problem. You'll have to devote a day to reading/learning before you get down and dirty with a handset....unless you have a few of these £500quid beasties you don't mind turning into paperweights!! Only trouble with this route is, once you've found a radio that works on Orange (and doesn't rinse your battery in two hours!), you're gonna have to repeat the HSPL/radio update process on 100 handsets, then re-install/re-configure each and every one.
Not a very inviting prospect (we "only" had 45 handsets to do!), but the end justifies the means. The HD2 is a marvellous handset - I know, I've got one (on T-Mobile UK ) and I wouldn't be without it.
Keep posting any questions/thoughts.....we'll be here to offer our "useful insights" and "helpful suggestions" as long as you can take it!!!
Good luck!!!

gsm/3g problem - dealbreaker :(

This might force me to use samsungs dead-on-arrival-refund and switch to the both uglier and slower Desire Unless you have a solution.
The phone finds several networks where two are associated with my telecom-provider. One is old gsm and one is 3g/H. I search and manually picks out the 3g-network and gets an H-connection with 2 mbps (max for what I pay for). But this only lasts for about 10 - 20 seconds, then it falls back to the gsm-network.
So to speek, it overrides my manually selected network and uses an automatic pick and i get gsm with crappy 56 kbps.
I have done this:
1. a new sim-card (telecom sent me one)
2. Resetted the phone (samsung asked me to do this)
The problem is still there and samsung now say I should send it back to them...
But what are the odds that it will work on another device... the problem is probably a combination of phone + telenetwork. The simcard works perfectly in the same location on the Touch HD (blackstone) and the sales-dude that also claims to have an SGS with another network have no problems.
Swedish telecom-provider: TELE2
Help...! I dont wanna switch to a 9 month old desire and the desire hd looks like the specs are the same as sgs without the samoled and a too large 4,3" screen.

Have you asked the sales dude which firmware he is using? This sounds a bit software related. It can definitely be teleco, however I think you're paying a premium doing more than keeping up appearances should be important to them.

Did you try setting the phone on "WCDMA ONLY" in the network menu?
Every time the phone gets a stronger GSM signal, it will switch to gsm, just like any other phone.
Just disable GSM.

hmmm no i have not tried that... sounds quite promissing, but if it works that will result in no network at all if i go outside a 3g-area, right?
I have stock rom at eclair.xwjfb - i90000xxjf5
But where do i find this option? from a secret code?
in the network-menu i only have "use only 2g networks"
EDIT
Found this:
*#*#4636#*#* for battery and other general setttings like GSM/CDMA
Testing.....
EDIT
No change
I set it to WCDMA ONLY and tried all the other options as well. Most of them resulted in to network access.
###! this sounded so good

so all i have to do is type that number i get the option to only use 3G covarge right? is that how you did it?
Tackar!

yes but read it again - did NOT work
are you having the same problem with tele2?

Ah okey, such a shame. Nope, i'm using Halebop, but if you have this problem i might also experiance it aswell, hopefully not though..
But my phone had a really strange problem which caused me to send it back, it lost the signal completly, like i had no simcard in it. This could accur around 20min-4 hours, and i seem to be the only one affected by this.. really strange, hopefully i'll get my phone back soon without this problem, whatever it might be..

im returning it today as a d-o-a and will hopefully get a new one that works. Would really be a shame to let go of such a nice handset!
the wifi-radio cant stay connected to dynamic ips either, something that clearly works for others with sgs

Just replace it with another. I think your unit is defective.
There have been no reports of network problems with the SGS, and personally, i live in a place with terrible coverage, but when i set to WCDMA only it still somehow manages to maintain a good signal.

surely this could also be due to not all places being covered by 3g signal.

possibly but not likely sinse i can manually force it to use another network and then max out the payed bandwith of 2 mbps easily, but only for a very short period of time...
anyway, its sent away now. Hopefully they fix this fast

GSM/WCDMA issues Vodafone Australia

Hi, most of my details re an issue are posted in the dev thread in the LeeDrOiD entry, basic issue is that my new DHD has been suffering from 'issues'
I am on Vodafone Australia and at the moment the network service sucks, and I have lodged complaints with them and the TIO as regards this.
My main issue is that calls went straight to voice mail and also lots of dropped calls, I have spent days and just now 7 solid hours trouble shooting, I have used 4 phones, 2 sim cards and have built/cleaned/rebuilt my DHD so many times I do not wish to think about it. After each build I could neither dial out or get calls.
For what it is worth, Vodafone say it is a network glitch, but I have now discovered what 'may' be causing the issue, I will need other non Vodafone peeps to try contact me tomorrow to confirm.
The 'fix' so far is to only enable GSM, it is set to GSM/WCDMA by default, either WCDMA or GSM/WCDMA make the phone fail, selecting GSM WORKS!!!
I have loaded and unloaded so many radios thinking that may be the issue, questioned each application I load as regards its impact and all it is looking like is a bloody setting that for some reason worked and now doesn't.
Let's see how vodafail answer this one...
Might be worth noting for your own testing at some point....

Could be you have poor 3G coverage at your area. The phone will then try to force 3G if it sees a tiny signal. This can cause loss of all connectivity. This happened to me once I was at Perth Airport. I'm with Optus and could not get make any calls or text if i had it on 3G. GSM only worked fine.
Could also be the phone handling changing from 3G to 2G very poorly. Never had this problem in Sydney though.

I agree with the guy above, I live south of you guys with no 3g coverage and for the first few weeks I had it in auto select and it was on 2g all the time. I use leeroids v1.4 with the radio recommended in the first post.

Hi silashack,
I am having exactly the same issue with my Standard UK Desire on Vodafone.
With WCDMA/GSM enabled the phone drops all the bars of service, then it will come back to full service but you cannot make or receive calls/txt messages or use the data connection.
Spent an hour on the phone with 1st level support and got nowhere (no surprises). I have a mate here at work with me, same phone, with VF as well and he is having the same issues as me, and they started at the same time last Thursday.
Do you think it could be a service fault?
Edit: No root here, just standard ROM. Come to think of it, there was a small update here a short while ago....

I am reading in a few places around the globe that these issues are NOT even country isolated, I thought it was just (possibly) Vodafone AU, but I have seen the very same issues mentioned on Vodafone UK and also Orange UK, T-Mobile and a few others, I do not even think it is isolated to the HTC Desire HD.
Would appear there is a global issue and it may be a while before the truth comes out
Well that one's for the tin foil hat brigade to play with...
I would have no issue if the feckin thing dropped to GSM and worked, moving back to WCDMA where available, but to just stop working is just not acceptable in 2011 FFS

As you guessed in an earlier post, it's definitely network related. H4tch3t over on one of the .za forums reckons he's solved it, and it's a mission I'm about to embark on as well (because not having my phone running at full capability is annoying as hell).

Vodaphone wcdma not working
Yeah I think you guys have nailed it this is nt an issue that can be fixed by the user it's a problem with the networks maybe a satellites gone down or something but one things for sure we will be the last to know

re
I just got the same issue in Sydney with Vodafone. My DHD worked fine yesterday morning. But afternoon, I can't make/receive any calls.
The mobile signal bar is full. But still.
I changed to GSM only. the phone call works fine.
I would call vodafone to check it.
they give me another reason to change to another operator.

sounds like congestion.

s4 data connection issue comes from my 9505...

Helo all..
I just brought that phone s4 9505 lte version for 1week ago. And at that time I did not find any issues on my phone. As u know I only checked using wifi and play games. It seems to work well everything. But today I am realized that something wrong in my galaxy s4 particularly when I use data network. The main problem is in the H symbol that always appear in the top of the screen with 2 sides arrow. When I do nothing with my phone or idle for a short while, the data connection suddenly stop working which means u can not browsing at all even making a call and texting. So the only way is to refresh the network or change the mode or restart your phone.
I dont know why it always happen in my phone many times. I have tried to refresh network and change the mode then give back to the wcdma mode. It occurs same issues again after a couple hours. But I did not notice where I use gsm mode.
About my signal is good. No drop signal at all. But I always encounter that problem. Maybe anyone who has the same issue .. plz inform then we can try searching out the solution. Thx

Addition information.. I buy this phone from singapore comes with official local warranty.
Actually. I have not tried to change another provider and I hope this cell is not fault factory.
I will try with different area and provider first then decide possibility

Are you on vodafone? There is quite some discussion going on in german forums where the lte - 3g change seems to be problematic when on vodafone network with the i9505. If so you might want to check forums like android-hilfe.de or so. Btw. Im in switzerland on provider swisscom and have the same problems. Data connections drops completely every few minutes. Very annoing.

Yes I notice in other sub thread there are quite a lots number signal problematic. Yet in my case is different from that case..
I just tested set into wcdma mode along night and until now it still work perfectly. This problem can not be predicted when it will occur. Sometimes I browse internet for 2 hours..afterwards my phone can not be used completely even testing and calling. I hope this is a provider caused.

[Q] Mobile data problem

I've got some problems with mobile data on my Note 4. I've bought unbranded phone in shop unrelated to any mobile provider. It's Snapdragon version (N910F).
I've got prepaid service, without LTE available (if that's important). The problem is that every now and then mobile data simply stops. There is still H or H+ sign in notification bar, and upload arrow blinks. but when i try to open web page or send message through viber, wattsup it acts like there is no network. Then i have to wait for about 30 seconds or manually turn mobile data off and then on again for internet to start working again.
I've tried changing APN settings, changing network type, but the problem is still there.
I've read some similar issues with Note 3 and SGS5 users, and some problems with modem versions, but i couldn't find anything from note 4 users
And this problem is very frustrating on phone like Note 4
Is there anything else i could try?

Mate i have exact same problem

I don't know if this is relevant, if your apn settings has a proxy and port values, try to delete it and let the proxy and port be blank. I had issues previously with data getting stuck while using proxy setting.

I also loose data signal and on calls people cant hear me properly.. doesny always happen. Ill try thanks

Also experiencing this with Tmobile UK.

Also have this exact same problem with the unbranded SM-N910H, H+ but no internet all of a sudden. I also sometimes lose the whole signal (Emergency Calls Only) so I have to reboot or turn airplane mode off and on to get it working again. I asked some people and they told me it's a coverage problem with the network provider. IDK if it's true.

No ahmadmob its the phone although i have n910u i have exact same problems as u!! I thinks its modem hopefully gets solved soon im in Australia using prepaid only 3g/h+

Glad it's not a carrier specific issue.
Guess I'll wait for an official fix or for other radios to become available.

I rang samsung australia few weeks ago and they had no idea than again when do they ever!? Lol so looks like we will have to wait buddy

Some common suggestions:
1- Swap the SIM card into another phone to see if the problem persists?
2- If the problem is due to Note 4, you may need to update your firmware/baseband to the latest one (if one is available, or you have to wait until Samsung release it), or try another firmware (from another model) or custom ROM.

Tried already mate sims fine updated reflashed stock rom and still same problem.. hopedully update comes soon

I just tried sim card from another carrier, and for now, everything looks fine.
I'll go ask for a new sim from my carrier, or switch my number to another one.

Sorry for digging, didn't want to make a new topic.
I'm here with the same problem. Did any of you find solution for it (other than switching to different carrier). I'm on Play in Poland and i find mobile data problematic mostly in roaming (free roaming with every carrier in Poland). For example on t-mobile or plus i find my up arrow constatnly blinking and H switching to H+ and again. Problem is even worse with 2 or less signal bars. I'm thinking of changing sim cars to new one, but on my note 2 everything works perfectly fine.

I thought I noticed a slight improvement after the final KitKat update, may have been a placebo effect though.
In general it's still bad, much worse than my HTC M7, same network, same location etc. It seems to be particularly bad when travelling at speed e.g. on the train I get full bars but only 1 arrow flickering.
Upgraded to Lollipop a couple of days ago and finally rooted, doubt this will make a difference but will be able to report during my commute tomorrow.
In summary: The HSDPA modem on my phone is rubbish.
P.S. Previous phones I've owned came with options for different modems, I'd often flash these to improve performance, where are they for the Note 4?

I think they're not available yet, at least on lollipop...

Mine is completely fixed after a few updates i get 4g+ here excellent reception

Could tell more how did you fix your problem?

All fixed!
I can confirm that after the lollipop 5.0.1 update on my SM-N910H all my mobile data problems/mobile network drop outs are solved!. 3 days without any problems now.
Edit: maybe it had something to do with Radio and it got fixed after it got updated along with the lollipop update package?

Guys, here in my country Bulgaria, many of us owners of SGN4 have the same issue and wilth Lollipop also. I have noticed that with KitKat the problem was more frequent than Lollipop but it is still there. We have tried Polish Lollipop and now the official Bulgarian Lollipop but the problem still exists. I hope somebody will tell me which ROM you have installed (oficial) so I could share it with my fellow citizens. Thank!
