Serious Bug: Device password freezes start menu after phone call

I have now done several test and have found what I believe is a serious bug in the ROM, making the Kaiser virtually useless for business users.
When the device is protected by a password (Start/Settings/Lock), the start menu freezes after ending phone calls. In addition, the backlight turns off.
This only happens if the phone call is long enough (more than a few secs) for the display to turn off during the call. This is to prevent accidental button presses. When the phone call is ended the display should come back up, however, this is where bug seems to manifest itself. Somehow the password protection gets in the way and turns the display off and freezes the start menu.
The reason why this is serious (especially for business users) is that when you use MS exchange sync, many businesses enforce policies requiring a device password (common & recommended practice). This means that the option of turning the device password off does not exist. Therefore, using exchange sync (with security policies enforced) and making phone calls does not work.
I have now made several hard resets and used two different SIM cards. However, I was not able to try this on adifferent device. Therefore, I would be grateful if somebody could try if they experience the same issue. Disabling the device password fixes this, so you won't be stuck if you try.
I will return my device tomorrow for a full refund, unless the store can show that this problem is specific to my device and that a replacement unit works properly.
Many thanks for any help!
Cheers

what rom are you using? I have not seen this problem at all on the various AT&T ROMs.

I am using the official & released HTC TyTN II ROM on a device branded as such. Got the device on Tuesday as official retail unit, so it is not pre-production or beta.
Interesting to hear it works on the ATT ROM. HTC must have messed it up. Maybe it is just my device.
Thanks for the info.

Ok, there is a workaround now that I can live with for the moment. All you have to do is to toggle the power off and on when it hangs and it is all back to normal. Not too bad.
Hope they fix it though...

Same error for me!
Hi Magxs
I cannot tell you how pleased I was to find that someone else has experiencing the same problem! I have _exactly_ the same issue. Like, you, I use the phone for business use so there is absolutely no way I can use it without a device pin (well done on discovering that by the way). As you mention in your last post, switching it on & off fixes the issue but it's a bit of a pain.
HTC have got a good reputation on getting fixes out quickly so let's hope that'll be the case here.

Always good to know you are not alone with a problem. I also have a thread about this over at MoDaCo: http://www.modaco.com/Bug-Device-password-fre-t258974.html
The issue is getting some attention now. Just hope it is enough for them to do something about it.

Hi
I have built a small application that will hopefully resolve this problem, it is over on the thread at: http://www.modaco.com/Bug-Device-password-fre-t258974.html
The problem with the Kaiser seems to be because on a call when it has a password set it's entering an "idle" mode rather than just turning off the backlight. Idle mode is something normally not used on PocketPCs. Once in idle mode it responds to key presses etc but doesn't leave "idle mode" so it appears frozen or in an odd state as nothing lights up!
Regards
Phil

I experienced even more issues!
Please can you share with me if you have found more complete solutions?
I experience "freezing" after long calls, same as you.
But also when replying to SMSs
Even when the device is not used for some minutes: first backlight goes off or almost off, then the start button (software and hardware buttons) become not responsive:solution? Soft reset! or wait 25 secs
Please help

Problem is widespread
I too have this exact same problem. If the phone screen goes off during the call, the end button will lock the screen. Have you noticed that pressing and holding the end button puts a screen lock on the device?. Never seen this in any other device. Normally holding the end button cancels the Data (HSDPA, GPRS etc) connection. I will try the solution and see how I go.
This is just one of a number of problems. I also find the phone goes in "Roaming" mode even when connected to my own provider, and there are annoying problems with calendar synching. Gr8 device...but!

KaiserCallEndFix.exe needed
I cannot log in to Modaco. Even after registration, no validation email sent to me. Can any friend here post the fix for TyTN II ( KaiserCallEndFix.exe) here, so I can download it!
Thank!

This has gone rather quiet, I'm using the Reg edit listed earlier that forces screen to stay on during call but it's not ideal.
Anyone else solved it besides the button press workaround or Phil's Exe file?

I also suffering a different side effect from this problem.
I choose to deactivate the lock function to avoid the on-off procedure after the end of everycall. But every 1-2 days my device stops working because it starts asking for the lock (even though the lock function is disabled!!!!!!).
If I soft reset the device the problem disappears. Does anybody also have this problem?
Is there any news on when HTC will definitely solve this issue?

this problem stilll exists. thought it was just me. Just got 2 phones from orange - complained tothem about this bug & they sent 1 replacement phone. even though I told them it was a software issue. new phone arrived and problem is still there . Orange have escalated the issue to their technical people. I await their response. I also spoke with HTC technical support in the UK who claimed not to be aware of this issue. One thing they did agree with was that if youhave a pin , when asked to input the numbers upon switching on the device , the screen goes half dimmed so you cant see properly what you are tapping in. no mention of a fix anytime soon though. lets hope HTC do sort this out an drelease a fix because I do really like this device.
great forum btw

My phone has had this issue since I got it back in Feb/Mar 08, i just hit the power button on/off and dealt with it. I'm suprised this thread is months only and HTC hasnt fixed it yet. Why are they so slow to fix issues?

omg, thanks god that i am not going crazy,
ive been using a mda vario 3 on t-mobile,
since dec 2008, got the same freezing problem...
hoping for a update to be released by htc etc, then got a replacement phone after 6months, and still same problem.
i just spoke to the technical dept and he doesnt know any problems with this,
thanks for the insight on how it occurs.
so now im gna have a serious complaint abt this, to t-mobile.
and get htc to sort it out.
heheh

Diamond: some production series better than others?

I just got my Diamond back from repairs and wanted to compare experiences:
1)
I first bought a Diamond two months ago. It came with 1.37 ROM series on it, the screen wasn't too yellowish, but touch function wasn't responsive and the GPS was a MESS!
(of course, I tried many ROMs official and unofficial, almost every Radio ROM and various Hard-SPL. None of that fixed the problems.)
I could cope with with the other flaws, but I just couldn't bear my GPS wasn't getting a fix, no matter how much sattelits were in view...
It worked at first, but soon started to display '66666' instead of the location and finally, it would never display any location again.
I tried every tips and tricks and softs, it helped giving me more and more satellits in view and apparently active, but at the end my crappy GPS could never turn the datas received into a proper location...
2)
I sent my device back to warranty (after flashing back to official ROM and SPL) and had to wait for about a month.
(the technician at first tought I was just a noob unable to set his phone properly, but after two days of attempts, he had to admit that there was something wrong with my phone and sent it to the the headquarter for replacement of motherboard and so on.
3)
The new phone I got came directly with 1.93 ROM and a little bit more yellowish screen, though, there is no spot or stain on it. So the coulour doesnt bother me.
But from the beginning I noticed the new phone was much more responsive even at the slightest touch.
From the first try, the GPS got a fix in about 1 mn time, with only 3-4 satelits in view.
I installed Hard-SPL and the latest Australian Official ROM, and though the screen seems now a little less responsive than before, the GPS is still working, fine.
I'm a VERY happy user of Diamond now, but I'm still wondering one thing:
it looks like once the warranty technicians understood that I was very demanding about quality and complete functions, they took time but gave me a phone totally different in terms of behaviour and quality of the components sensitivity of screen, GPS etc.
Is there some bad production series that they never tells publicly about, and much more better series that they give you as a replacement once they understand you will bother them until the end of time if you are not satsified?
Plz tell your experience about having received two new diamonds with totally different behaviour and quality of the components.

I guess you are totally right!!!
My first device was pealing paint in the aluminium frame on the second day, work very good by the way.
Now i´m on the second device and i my hardware keys, especially the call button is sometimes irresponsive and i have to push it several times to enter the dial.
Tried cooked rooms as well, and the call button issue still remains, so i´m a little unhappy with my diamond experience.

I've noticed that whenever i turn on my display after having left the diamond unused for sometime the lcd doesn't switch on smoothly, what i mean is that it first displays a grey pattern(only for a ms or so) and then the desktop( lcd off>>grey flash>>desktop). Usually the transition from off to desktop is quite smooth, but in my case its not!
Is this a s/w issue or h/w ?

I've never experienced that particular problem myself, but sounds like H/W problem to me...

just been through a couple of other threads related to the grey screen of death...i've had it once...it happened while i ended a call, had to soft reset to resolve it.
take a look at the grey screen of death i'm talking about

Pretty scary indeed!
It might not be a coincidence that you experienced both: grey transition when switching on the screen and once, the grey screen of death after a call...
Two different effects of the same defective part in your H/W?

a solution!, almost
untill now i've had auto brightness control switched off and the brightness was set to minimum to save battery life, but now i just tried switching on auto adjust backlight and the problem seems to have vanished.....coming out of standby is smooth as ever!
although i've to say that i don't quite understand the logic behind it.
*EDIT*
it doesn't help for long

This is what I was worrying about...
Your method sounded like a work around to avoid the display failure. But as a matter of fact, there must be a reason for the display to fail. (bad screen, power supply or something...)
By the way, I'm more and more convinced about my assumption that there are bad production series and better ones:
Today I had my device connected to my PC through USB for a couple of hours. In the meantime, I was downloading and deleting messages, watching google video on opera, after that I used wifi etc.
In this situation, my first Diamond would have got hot like hell and my hand could barely stand the pain...
Since many people were complaining about over-heat problems, I thought that was a common problem with Diamond.
But the new one did not get that hot. Just a little over-warmed, but definitely not too hot. From that phenomenon, I can see what I felt about a better touch-flow behaviour, a better GPS and so on is a part of a whole:
I was first sold a ****ty phone, and now I finally got a proper Diamond!
People with bad series, you don't have to cope with all those troubles, ask for a replacement phone!

my diamond gets heated up quite a bit at times....but i dont fully uderstand what exactly is the cause.....i've had experiences with the diamond getting pretty hot while using wifi & or gps and on another occasion i was watching a DVDRIP via wifi(@ full power) using core player and also with gps cycle running in the backgroud, still the diamond stayed well within reasonable limits.
i think it has to be a software problem, possibly the radio s/w
would you mind sharing the radio version of your diamond?

As written in my signature, I'm using the 1.00.25 which is included in all latest official ROMs.
By the way, I hope you did not cast a spell on me! (just kidding)
Today I experienced my first grey screen!!!
My Diamond was connected to the PC through USB cable, downloading e-mails, and I got a phone call. When I hung the phone, It suddainly happened, for the first time in my Diamond user carreer!
Just for one second, looking like an old black and white TV screen trying to tune on channels.
Hope that was the first and last time. In ordinary calls, (without being synchronized to the PC at the same time, it never happened so far...

sorry to hear that my friend

I'd the same experience except for the fact that my diamond wasn't connected to a PC.
I hard reseted my diamond yesterday, but the grey splash while i turn on the display from standby(post 3) still exists ( ......i don't suppose its a software problem anymore.

Why not trying to send it back to the seller and get a new one?
This problem is easy to demonstrate to the technicians, and I don't think they will be cheeky enough to say that's a normal phenomenon!

not that easy.....the thing is that if we turn on & off the lcd without a gap of atleast 4-5 min(dono exactly) i dont see that grey splash
i think im going to wait another 3-4 months before i approach for warranty.

I had that "gray splash" problem with my Kaiser and Diamond.
Hard reset also didn't work like above. For both devices the fix was simply flashing to a different (cooked) ROM.

As mentioned in another thread, the grey screen problem was fixed (as least for me when I flashed to dutty's rom)

You can stay there and wait for 5 more minutes in the shop while they are attending other customers, just to proove your point.
If they are honest, they will not deny the fact!

There might be some tweaks in the cooked ROMs that avoid the problem, or it might be due to some bad flashing or defective hardware.
If not, how do you explain that I've never experienced this with my previous HTC phones (wizard, Trinity...) nor I experienced it with my Diamonds (the first one and the new one) with stock or cooked ROMs.
except for that very special time, when I received a call while downloading messages through Active Sync.

Nexus One Screen Accuracy Issues

Hi
I purchased my AT&T 3G compatible Nexus One the first day it went on sale, I just updated to Froyo and I notice that sometimes my screen fails to respond. I have to power on and off my screen for the issue to go away. Some examples are when im typing and I hit and key and it chooses another one or i'm trying to scroll on the menu and even if im picking something from the top the phone highlights the menu icon at the bottom. Are this issue just with my phone? has anybody been able to fix this?, If i call HTC support and they send me and new phone will it have the same issues?
Please guys let me know... this is driving me crazy

the screen on this phone blows... plain and simple... you will just have to get used to it...

do you think i should get rid of it?

Hi,
Don't get rid of the phone. You don't have to reboot, just lock the screen by pressing the power button, then unlock it. I've had it a couple of times but it goes away when I do that.

Also, be aware that it's very sensitive to any part of your hand that might be leaning over the edge of the screen, or hovering over the touch buttons. For example if my finger is hovering over the home button but not touching it, and then I touch somewhere higher up on the screen, it may respond as if I had pressed menu.

So...are you saying we are holding the phone the wrong way? Lol.

the nexus has this issue with the screen. its not a big deal, just lock the screen and unlock it, it fixes the problem. its some kind of mis calibration issue. yeah it sucks, but not the end of the world. only takes 2 seconds to fix it.

Heehee. I guess Android isn't immune to that either. Nor is the EVO or Droid Incredible (not identical problems but they're still there). I think it's inevitable that as we try and jam more and more "magic" into a single unit, things start to crosstalk in unpredictable ways and glitches emerge.
I have to say, the touch-sensitive buttons on Milestone & N1 really throw off people who haven't used them before. If I pull up a picture or video and I'm showing it to someone, inevitably they clutch the phone with a finger on a touch button, and then I have to get them back into the app and explain what not to touch. That's one reason I'd rather have physical buttons such as on the Desire.

I have this touchscreen problem as well, and yes its a big deal for me! I spent $580.00 for this phone. This shouldnt be happening at all! I've tried all sorts of troubleshooting(deleting cache partition, updating to the latest froyo, restoring factory settings, tried without installing 3rd party softwares, etc..) before i finally came to the realization that this is a hardware issue. Ive tried narrowing down to possibly when and how it occurs, but you can't. It just happens when it happens. It's impossible to predict. When this problem occurs, watch closely to where the calibration is off. During the problem, the calibration is only off on the bottom half of the screen, more so close to the bottom right. The top part will work perfectly. You can test this out by swiping left to right or vice versa on the homescreen. This problem will also affect the Pinch-to-Zoom in Browser, and the ability to type correctly using the default keyboard or 3rd party's like Swype. I received an exchange thru HTC a couple days ago, and not only was this exact touchscreen issue prevalent in this unit, but also it suffered from the purplish screen tint. This issue seems to have existed since they first launched this phone, but for some reason there has been no fix for it. It's funny that the EVO received a software fix promptly after the issue was reported by many. Why not the N1?? Because it's hardware, that's why! Feature wise, this phone is by far my best PDA, I mean I really love this phone, but $580.00 is too much for such an issue to exist. I'm hoping that there's only a number of bad batches floating around. I would say, if i receive 4 exchanges, all with the same exact issue, i may look into a class action. I definitely wouldn't want to be stuck with this problem after my year warranty is up!

I haven't had the 'crazy screen' thing since FRF85B, I assumed they'd fixed it.

I haven't had it since upgraded to Froyo too

not hardware problem
I encounter this problem a couple of times and I tested two things: useing trackball I ran touch sens app and tested the touch sensor, it was fine, second I killed all apps using a task man and it fixed the issue. I am on froyo.
Sent by my Nexus one.

I experienced this yesterday for the first time on FRF91 (unrooted Stock build). I couldn't press the "enter" button on stock keyboard. It just kept choosing Delete instead. Lock/unlock screen via power button sorted it.
So the problem is still there in latest build of FroYo (for me anyhow!)
Anyone else?

I've had this problem ever since I got my N1. Sometimes made me want to switch back to my iPhone! Makes it a lot harder for my son (2 1/2) to use the phone too.
Seems reports are mixed to whether froyo fixes it or not. But it gives me hope. I've been using CM5.0.8, holding out for their final release but this gives me a reason to try MCR.

I have upgraded to FroYo FRF91 but still see the same issue.
Sometimes I face with the calibration's flaw for the left bottom corner of the touch screen.
What a shame I have paid 750$ here for this phone. I really love it but this flaw screwed up all the pleasure.

[Q] Unresponsive Touchscreen?

Hello my fellow android hackers, I need your help. Recently, my touchscreen has been completely unresponsive at the top of the screen, near the notifications bar area, but three times as thick. The problem with this (Besides having to go to my homescreen every time I need to access my notifications, or having to go into landscape mode) is that It often renders my phone useless. Often times when I select an object or slide across homescreens, the UI will select an object at the top of the screen. Shortly after, I will be unable to select anything on the screen, and if I try, the UI will select something at the top of the screen and will begin erratic movements around the homescreens, web browser, and almost any touchscreen interaction. This movement will occur whenever I try to interact with the phone's touchscreen whenever it is in this state.
This is not native to any rom, I've tried reflashing and trying many different roms. I know the touchscreen malfunction is native to the hardware, since I've tried reflashing the 2.xx.x.x.xx.6 and the 2.xx.x.x.xx.5 ruu. I think I will need to replace the touchscreen, so could anyone direct me to where to buy the part, a website to install the part, or both. I'm pretty sure I can find how to install the part, just not where to get it. Also, I'm not sure if it's a problem with the inner or outer lcd screen.
ANYWAYS, this problem is more common with the HTC Hero GSM, but HTC has said that some hero's have bad touchscreens.
Heres a link to a video demonstrating the problem. (I am running CM 6.0.0 test 2, it's a great rom)
http://www.youtube.com/watch?v=1ORe2rjWt7A&feature=related
This is with the hero cdma, but the broken area is on the side of the screen, not top.
http://www.youtube.com/watch?v=JYQnCOAtTLs&feature=related
This is to the GSM hero, but the issue is with the bottom of the screen.
This is a problem native to the HARDWARE, and occurred during normal use of the phone, just shortly after watching youtube videos and browsing the web.
Could anyone even direct me to a location to get this repaired, since the Sprint store said there was no way to fix it, but online many people had this issue and got it repaired by HTC customer care. Could anyone confirm this, or state the time length of a cdma sprint hero warranty purchased from Sprint in the US?
(Occassionally the phone works, but only for a short while and then It starts acting up again, usally during data use, like web browsing or using several apps)
Any help would be appreciated.

Is it humid where you live? Do you use a screen protector?
Sent from my HERO200 using XDA App

Yes, it is humid, and I don't use a screen protector. I think the processor was overheating during heavy use (watching video, etc) and I left the screen on for a while. I think that this damaged the screen.

Have you tried a different rom, or maybe flashing one of the new any kernels for your current rom? Almost sounds like it could be a driver issue. I did have a friend that had this problem on his stock hero, and sprint replaced it for him. If you ruu and it still does it, make a scene, they will replace it.

had the same problem with my hero, unresponsive directly below notification bar, as well as becoming completely useless randomly. took it into sprint, and the tech seemed to know exactly what the problem was. an hour later, it was fixed as well as my peeling buttons replaced...free. apparently the touch sensor was going out and it must happen more often than not considering the tech new what the issue was immediately.

Ok, I will not start another rant and rave I promise, BUT, I will say be very careful going to Sprint with a problem. I just had the same exact problem, I had to go to FOUR different stores, and finally instead of fixing my SPOTLESS Hero, they ordered me a "new" one, it has scratches all over the screen, the back cover hangs off, my hardware buttons(home,menu,ect...)are lose, and the metal where the ear speaker is is sticking out, be very careful dealing with sprint.Oh, yes this all happened in the last 4 days, they didnt give me a loner phone, and it took me 3 days to get this piece of **** they call a new phone. Just my experience.

[Q] Touch malfunction

Hello lovely people of XDA.
Both my wife and me have the Z1, i for my part have experienced screen self cracking and now she is experiencing touch malfunction.
It acts out from time to time, making typing a pain in the a** and playing games even more dificult.
F.ex. if she presses the F key, it registers the D etc.
Ive made a video of this availible here:
http://youtu.be/McGnrGfVpq8 (Sorry about the music, but there was too mutch background noise).
This happens on the home screen, during Candy Crush(yeah i know) and during texting.
Ive repaired the phone twice(previous and newest firmware) via Sony PC Software and still its no good.
It even acted out on the first boot.
Has anyone ever seen anything like this?
Can't seem too find any solution.

Theres a well documented thread about touchscreen issues, I myself was one of the people it affected, your problem sounds slightly different.
The method to test was put the phone on a flat surface and make contact with the screen, move around and if you notice a break in contact then you more than likely have the bug.
Holding the metal frame of the phone in your hand eradicated the issue for some (me included) but it was certainly a pain.
My problem went away on it's own but some weren't so lucky.
Have a search for the thread in here, it's more than likely still active.
If nothing helps from that thread then it's more than likely a case of doing a warranty repair. (if it's the same issue)

Hello there and thank you for your reply.
As it seems to me there has been no solution to the problem, ive tried holding the phone without a case and the problem persist.
People are talking about the new update fixing it, but ive tried both updating and reseting the phone so that did not do anything.
It seems like the only thing to do is to send it in for a warranty repair.
With my self cracking the workshop told me that some of the frames where faulty placed in the factory and therefore might crack the screen after a long time under pressure.
Perhaps this is related somehow, though it feels and looks like a software bug.
Thank you for your reply, i'll be sure to keep a look out on that thread. (i found it now, but i could not find it before i posted this :S)
Thanks again

The kitkat update was rumored to remedy these touch screen issues. Have you updated? My C6906 was giving me occasional touch screen issues but they are non-existent after updating.
Sent from my C6906 using XDA Premium 4 mobile app

Yes i have installed Kit Kat, seemed to help at first but started acting out again the same day.
I even did a factory reset with newest firmware downloaded through PC Companion.
I'll keep looking around and post my findings.(If any)
Update:
So we both sent our phones to the service center and sold them right afterwards. Could not find a solution for the problem and the service center ended up replacing my handset and my wifes screen.
I now have a Nexus 6(it's so fantastic!) and she has an iPhone6 plus(Blaaarh...)...
