Home button going haywire; any fix? - Bravo General

I have a Motorola Bravo that has been working marvelously for me since I got it in early August. However it's been acting up lately. Constantly the phone starts vibrating in short, rapid bursts and the interface on the phone keeps going to the home screen and eventually showing whatever the Home button was programmed to. I'm guessing it's the Home button itself that is messed up, it seems like it's being triggered constantly by something. The phone works completely fine outside of this rapid, phantom button pressing. It's definitely not a software issue (I completed several resets to get back to stock) and I don't recall anything happening that would trigger a hardware issue. It's been in an Otterbox Commuter case it's whole life and I've babied it pretty well. No drops, no water, not even a scratch on it. Even took the protective screen off in case that was causing something. It just randomly started doing this last week. The bursts last several seconds and are spaced only a few seconds apart, making the phone pretty much useless. It seems to be getting more and more frequent as time goes on too.
Has anyone had this problem? Is there any DIY fix without voiding my warranty or should I just use up the warranty on this?
Thanks - Kevin

Two things
Try #1 At home try the "real" factory reset with RSD Lite and your 2.2.1 .sbf file.
Try #2 Take it back to the store as a manufacture defect. Not insurance issue.
Best of luck to ya.

Crazy Tytn screen and button problem, please help

Hi all, this is my first post on this forum but I've been reading for a while to educate myself.
I've got a Herm200 that I've been trying to troubleshoot but to no avail. I'm fairly certain that it has a hardware problem but I haven't been able to isolate anything.
Here's whats happening:
Occasionally the screen will come out of stand-by all white. This will also happen randomly if i touch the screen to perform a command. While the screen is operating, sometimes the buttons on the face will stop working, however the buttons across both sides will continue working just fine.
When the screen turns all white a soft, hard, or stand-by cycle will not always bring it back to life. The fact that the hard reset wont always fix the problem makes me think it's a hardware issue since the phone will boot-up with the the all-white screen.
This is incredibly frustrating especially since HTC wont accept any warranty claims in the USA on the Tytn.
At first I thought this might be a problem with the ribon connection between the screen and the base but i haven't been able to confirm or discount anything at this point. I have yet to find a way to consistently reproduce or rectify the problem so it's very hard to troubleshoot.
I pretty much have to take a second phone with me everywhere right now just incase i need to make a call. Please help! Has anyone ever encountered such a problem?
Thank you in advance!

Hi. This sounds very similar to a problem that I experienced with a HERMES100. I bought the phone off someone on Ebay recently - someone had obviously scrambled the radio on it. I re-flashed it, and it sprang to life. However, after a couple of days, I experienced a problem where occasionally the LCD would stop refreshing, all the pixels faded away leaving only a white screen. Under these circumstances, some of the buttons on the phone stopped working. Turning phone on/off sometimes cured the problem, or it would require the occasional hard reset. This would happen once or twice a day and I suspect thats why someone tried to re-flash the phone.
In the end, out of curiosity I took the entire phone apart, put it all back together again and now there are no more problems!! Totally fixed!
My suspicion is that it was one of the ribbon cable push connectors on the mainboard - possibly not seated properly, or a bit of dirt contaminating the connection. Obviously when I took the phone apart I must have re-seated it.
If you are planning to take your phone apart, please exercise considerable care because some of the parts are very small and easily damaged. I would recommend buying a proper kit to take it apart. I bought mine for about £5 off ebay. Particularly useful are the plastic spoon "wedges" used to gently prise open the case after removing the screens. Don't use a screwdriver - you will scratch the case.
Good luck.
wow... that sounds like exactly what's going on here, I actually even tried to disassemble it lastnight but didnt have the right driver set. thank you for the advice!
I'll look for one of those sets but what would you search for if i needed to find it?
Thanks again, I just got a set off of Ebay. Hopefully it'll be here next week
With any luck it'll be a connection issue.
I have had the exact same problem. Because I got the Tytn through work I made our IT department handle the issue and I am currently waiting for a replacement and to find out what happened.
Yep, it looks like the problems the OP is having are very similar to the problems we've been having over in this thread:
http://forum.xda-developers.com/showthread.php?t=291027
I'm beginning to think it's a hardware problem as well but not entirely sure.
People in the above thread mentioned that using the scroll wheel a while then moving back to use the D pad fixed the problem (very briefly in my case.) Once I use the center D pad button again it locks the hardware buttons under the screen until I make my device sleep and resume.
Somtimes rather than making all the front hardware buttons unresponsive the issue is that once I use the Down Dpad button I can't use the up button. Pressing up will make it go down, as will pressing down (at least that's working ).
Regarding the white screen - this sometimes also occurs. I can force it to white screen by putting a little pressure on the silver panel surrounding the top, right and bottom of the screen (I have an imate jasjam). Randomly when there's no pressure on the rim and I wake it out of standby, it has a white screen that can only be fixed by turning the screen off and on again.
Finally, the LED indicator seems screwy. Sometimes it never flashes. Other times it flashes sporadically (uneven intervals - we're talking maybe a minute between one flash then seconds before another). When I charge it sometimes the LED doesn't come on but nevertheless it charges. Sometimes if the LED is on it never turns green to indicate a full charge. Yet other times it comes on orange, turns green, then never switches off!
Is it possible that
a) The hardware button problems.
b) The white screen problem.
c) The LED problem.
are all related to some kind of connection going loose? Why would the hardware button problem be temporarily fixable with use of the scroll wheel if this were the case?
The other thread has fallen silent. I'm hoping that some of the gurus in here can offer some input here, even if they don't know the answer but can formulate an opinion. I know very little about these devices.
Thanks in advance guys!
PS - don't really know if I should start another thread, I've posted here as it seems like very much the same issue.
Anybody any idea? advice?
I had a similar problem with my HERM100. I didn't mess around with it too much, I just had Cingular replace it out of warranty exchange (thank god those original ROMs are on the wiki ). I did notice however that after doing a master reset, the screen would function again although I haven't messed around with it too much. I got so frustrated with removing the battery for 5 minutes and STILL powering on with a white screen that I just threw it in my back seat until the new one arrived.
I don't have these screen issues. I only have hardware button problems. It's so damn frustrating! I already own a replacement.
I just received a call from my girlfriend. I wasn't able to answer the phone with the buttons, only with a screentap. I also wasn't able to close the call with the hardware button. Since the side buttons work, I went to settings -> phone, closed it, and there we go. The hardware buttons worked again.
Why the heck is this? I truly hope for some wizz out there with some advice, since HTC would only tell me to send it back after replacing it with a new TyTN with same issues.
Regards,
DM.
Anyone anyone?

This is my first post as I've so far managed to cure all my issues from just reading the forum. However, I am now having a similar problem with the white screen.
I have a cingular 8525. It fell and the following day the call and end buttons remained lit and wouldn't turn off and they also wouldn't work.
I soft reset, nothing, I then removed the battery and when I turned it back on, there was a white screen and the buttons below still don't work.
I have read the other posts on this issue, but I need help on exactly what kit to buy to reconnect the screen cable and instructions on how to do it as I've never taken apart a phone before, although I have dabbled with other electronic devices.
Your help would be much appreciated, as I am in Jamaica and there are no technicians here who I trust to help.
Thanks in advance.
Below are links to 2 kits I'm thinking of getting. Is either one better than the other?

Both kits look ok. PDA one tells you a little more but the basics appear to be in both.
I'm curious though you soft reset and took the battery out, but have you done a HARD reset? I would always try this first before dismantling.
Mike
In my case, they also are always lit up when the screen is also active.
And no matter what ROM version, they occasionally stop responding. Side buttons keep working.

Thanks for the response.
I couldn't do a hard reset because the buttons weren't working.
I have made some progress with the phone now. Found a tech guy who looked at it for me. The white screen is gone, but the buttons still stop working from time to time.
All the connections seem ok.
Is there anything else that could cause the buttons to malfunction?

Nothing obvious.
Have you got applications installed that you have loaded - could be one thats playing up.
Have you now been able to do a hard reset?
If taking device apart and reassembling improved things it does suggest hardware though and might be worth double checking all those multi-connector blocks for good connections - i.e. take them out and in a few times to ensure any oxidation on contacts is removed.

If it wouldn't be a software issue, why is it, in my case, instantly resolved when going to settings -> phone with the side buttons?
i had this problem i took it to a guy who fixed the problem he said it was a very small tear in the flex cable which causes this white screen every now ant then and the buton problem , sorry to say its the cable problem and u need a very capable person to fix it or replace it with a new one . its very common problem baised on the guy who fixed it .

Exactly what is happening to me, no white screen issues, just screen taps and answering calls, I also have another problem where the PDA will not allow me to open anything, be it the start menu or contacts, it will open and quickly close again. I have had mine swapped through Telstra in Sydney, it worked fine for a while and then the same crap again. These problems started before I even touched the OS, so it must be a build problem. Maybe we should write a joint letter to HTC letting them know that there is a serious problem with their machine.
I have had the same problem, got my Tytn through work so we sent it back to the company that supplied it to us. Got it back yesterday and they had replaced the "switchboard". Not sure what it is but there was the problem. Had white screen and buttons not working.

Home key losing functionality

Picked up my Vibrant on launch day and it's been great through the weekend, now about an hour ago the home key seems to be flaking out on me. The other three keys are still as responsive as ever, but I have to hold my thumb perfectly still for about 5 seconds before it registers, if at all. Is anyone seeing issues like this on their Galaxy? Or on similar hardware?
Dosent seem to be anything physically interfering, and no there were not any drops, falls or accidental sittings. I'll swing into a tmo store tomorrow, but figured I check in with you folks until then.
Doesn't happen on mine, probably defective device sadly .
Mines working great also... Sorry to hear
Thanks for the responses, unfortunately it looks like I'm not alone...

Tried restarting?
I did, a few times. Nothing.
I had the same problem. The home button would not respond to multiple touches, so I completely drained and charged the battery, now it works without any problems. I'm not sure if its fixed completely or just a temporary fix but so far so good.
Had the same exact problem! the next day after i got the phone i noticed that the home button would not work right, had to press it multiple times while the rest of the buttons seemed fine. I just went back to the store and replaced the phone. Everything seems to be working great now. I bet its a manufacturing screw up seeing how many people have the same issue. I would just replaced the phone and hope your next one doesnt eat sh*t
Any updates on this? I didn't have the problem until today, now my home key only works when not lit up. So if the keys are lit up and I want to use it I have to wait for the phone to go idle after a second and then hit it... I will call radio shack tomorrow and see if I can do an in-store return or since I ordered it online if I will have to mail it back, I will call the one far away so I can see if I just show up in store and fail to tell them I ordered it online if they will just do a swap for me there, and I can try that at tmobile as well... it's a 1 for 1 trade off so they aren't losing out (on much)...
I have the same issue. Sometimes it goes away but it always come back, even after factory reset. It seems like a shoddy manufacturing process. Just be glad you aren't a t-mobile employee as I have to ship it back before getting a replacement for the broken phone they sold me.
Sorry for reviving such an old post, but I stumbled on a solution of sorts to this issue of unresponsive capacitive buttons which I can reproduce 100% of the time.
This sounds silly, but I noticed the last week that whenever my home button decides to flake out on me switching live wallpapers brings it back to life. The button will then function perfectly for anywhere from a few hours to a few days, flake out again and then be brought back by a live wallpaper switch. No reseting, or changing of settings beyond the LW.
I just wanted to throw this out there, if only because many were guessing this seemingly common problem was a hardare issue and in my experience it's looking to be very much a software issue. Now I just have to figure out what's killing the button in the first place.
paxton, I tried your solution but it doesn't seem to do anything for me. I'm still at a loss.
I called Tmobile but tech service wants me to ship my phone back to them phone at my own cost. They forwarded me back to customer service when I refused. Anyone else having problems dealing with TMO? I'm worried that if I return the phone using buyer's remorse, I'll lose my Bing cash back.
i kinda had the same problem, just all buttons didnt seem so sensetive. So I removed my zag for reasons of it being sticky feeling during games like nova. Now my buttons respond so well. Thats how they should be...
i ONLY have this issue when i have a live wallpaper and also when the lights of the buttons are on, as soon as they time out i can press the home button and it will work

I had the same problem... Removing the screen protector seemed to fix all issues. Oddly enough, it was only my home button that was having poor responsiveness.

Bad touchscreen?

Have there been any reports of bad touchscreens? We just got our EVO's a week or two ago, and my wife has been complaining that it's not responding to her touches and she has to select things multiple times. I noticed it somewhere too when messing with her phone but thought it an anomoloy. Now I'm a bit concerned.
Since we are within 30 days, and the phone has had no abuse, would this be covered by any warranty even if I don't have Sprint insurance?
What steps should I take? Is there anything I can do to further test the touchscreen to see if it's really bad?
I'm going to remove the screen protector tonight just in case that is causing the issue. Has anyone had any similar issues?
I would take it into the store ASAP
Anyone else have any sort of issues like this?
What software versions are you guys running?
There were some pretty bad touch response problems with the first couple versions of 2.1. I think the first 1.47 was when they fixed them.
Until you use the phone without a screen protector its hard to say if its really the screen. If it is still doing it then yes that would be an exchange issue and should cost you nothing.
My wife has nails (not even long nails, but long enough), and when she uses my Evo, she has to use the ball of her fingertips instead of the top of her finger. She can try and press the same spot repeatedly and it won't register, whereas it always goes through the first time when I use my fingertip. She gets incredibaly frustrated in the car when we're listening to pandora, and she tries to thumb up or thumb down a song. She'll press it 10 times and nothing, but when I hit the same exact spot, it will work the first time, every time.
I think it's funny.

I have lost interest in the Surround and can't wait to upgrade

First I lose the screen as I back into something and a piece of metal barely tapped the screen and it was enough to crack it. I got it replaced and a week later the SD card went bad (couldn't save it regardless of the deep format options I tried). That forced me to buy a new card and have to re-install about 80-100 apps and games and re-configure everything.
It' been about a month since then and I get a call this morning. Upon hanging up the screen won't turn back on. I think...whatever. I pull the battery to reboot it and bam...at the Windows Phone 7 logo screen it starts to vibrate............and vibrate....and vibrate. Great...it won't stop vibrating. Looking it up online it seems the ONLY way to fix it...is to hard reset it AGAIN. $^#$^ that lol.
So the vibrator conveniently has a open window to it right above the LED flash so you can see it without having to remove the layers of plastic. I took a piece of tape, rolled it up and cut it down....and jammed it in their to prevent it from spinning.....phone works fine now (just simply dont have vibrate options now).
Hopefully when MS gets off their arse and launches Mango, the update will reset whatever screwed up setting it is that is causing it to flip out and I can take the tape out. That is...if the motor doesn't some how burn out from being jammed ^^.
Maybe I should have gone with the Samsung :/
At lease someone can benefit from this if their vibrate screws up and they don't want to hard reset. Just jam the little guy from moving! It's not like your losing anything...the vibrate on the Surround is so low, most of the time you don't even feel it go off in your pocket.
09/22/2011 Update: Well then! This proves a success for those having this issue in the future. Many HTC phones seem to have experienced this (based on searching out the vibration issues google). I removed the tape this evening, and the vibrator was still. At first I assumed it must have been burnt out from keeping it from spinning...as it was still generating power (eating through the battery that whole time)......but after testing it out...everything is back to normal. Vibration function is working fine. So I guess if you wait it out, it corrects itself eventually. How...I don't know...but I recommend jamming the motor if you ever experience it vs letting it vibrate continually for a day or two which prob would burn it out. No hard reset needed!I still want a new phone though...something just as thin but with a slide out keyboard and duel proc and cams
My surround works well all the time

[Q] Anyone else have touchscreen problems

My phone last week wasn't receiving texts so I restarted it and when it came back on the touchscreen no longer worked. The little white light would go on when I touched it so it knew where my finger was but any movement would not unlock the phone so I couldn't actually do anything with it. Sure enough a factory reset fixed the problem but I am still waiting for them to get me a new one in case the problem happens again to me. Anyone else have this happen to them or just a freak occurrence for me?
My son has gotten a hold of my s4 twice now since I have owned it. Both times I couldn't get the phone unlocked even though the touch screen was recognizing my touch. Restarting fixed it both times for me. Not sure if this is the same problem you are talking about, just thought I would share.
Sent from my SAMSUNG-SGH-I337 using Tapatalk 2
Happened to me a few times. Both screen swipes and the capacitive button presses werent registering. Happened on lock screen, call logs (swiping to call wasnt working), and swipe to answer. Pressing the home button and going back to the app fixed it. Very random but annoying nonetheless especially when not able to answer a call
Seems like buggy software to me. I've had a different issue, my phone says I have data, but I don't, I've had to restart the phone to properly pick up a data signal. This has happened twice now. Seems to be like Samsung's touchwhiz is quite buggy...
Yeah restarting it did nothing for me, tried many times, took the battery out put it back in all that stuff. The same thing happened with my data, I had a connection that entire time that I was not receiving texts but none of them actually went through which is when the problem began.

What app were you able to get in to to fix it? Would like to know in case the problem happens again when they get me a new one.
This happened to me last night, about had a major freak out.
First I have a couple questions for all of you who had this issue, so maybe we can pinpoint the actual cause:
1. Did you get any type of moisture (even just a little condensation) anywhere on or around the phone? Mine started acting up after I accidentally put my phone on the coffee table where some condensation had formed from a drink being there previously.
2. Any of you drop your phone at all? Even just a minor drop...as the day before I had a little drop (maybe from a foot off the ground), but I do have a case.
The reason I ask is because I started having this issue immediately after the phone was put on the condensation. Don't know if that was the cause, though, because I'm not sure exactly which of the steps below actually fixed it.
First I had to identify the exact problem...which I found by turning on "show touches" in Developer Options within the settings menu. This brings up a little white dot on the screen any time it registers a touch. Sure enough, I was getting "ghost touches" on the top left corner of my screen every 30 seconds or so - and it would generally last for 10-30 seconds or until I turned my screen on and off (that would fix it temporarily). The ghost touch was causing my drop down menu to pull down slightly every once in awhile, as well as not registering any of my other touches (including capacitive buttons). I knew the screen itself wasn't broken, because any addition touches were registering via the white dot - they just weren't interacting with the UI.
After doing some research online, apparently there are a couple main reasons that this ghost touching could occur:.
1. Faulty digitizer. Obviously this would Suck, and I really hoped it wasn't the cause. To repair would mean replacing the entire screen, as apparently the digitizer is attached to the screen and would be very difficult to replace by itself.
2. Any kind of moisture, whether water, skin oil, etc, getting in the cracks of the phone and staying under the screen, causing the pressure to indicate a false touch. Possible repair options included putting the phone near a WARM (but not too hot) surface for a period of time to hopefully cause the moisture to evaporate. Also some people said it just evaporated on its own after a few days (again, I hoped I wouldn't have to resort to this as I'm impatient and don't want to be without my phone for that long lol).
3. Software issue. Possible fix includes toggling HW overlays and/or GPU rendering.
Here's what I did:
Took the phone apart completely, made sure there was no visible moisture anywhere (there wasn't). Intermittently blew the phone (from the back and front, while it was disassembled) with warm air from a blow dryer. Left it alone, disassembled, for about 30 minutes.
Put the phone back together, booted up, immediately went to developer Options and (a) disabled HW overlays and (b) DISABLED "Force GPU rendering" (I actually already had it enabled).
BOOM - problem was gone!
So like I said, I'm not sure which of those did the trick - or which problem I had to begin with - but I'd be interested to know if anyone else had similar issues and/or fixes?

1. Faulty digitizer. Obviously this would Suck, and I really hoped it wasn't the cause. To repair would mean replacing the entire screen, as apparently the digitizer is attached to the screen and would be very difficult to replace by itself.
2. Any kind of moisture, whether water, skin oil, etc, getting in the cracks of the phone and staying under the screen, causing the pressure to indicate a false touch. Possible repair options included putting the phone near a WARM (but not too hot) surface for a period of time to hopefully cause the moisture to evaporate. Also some people said it just evaporated on its own after a few days (again, I hoped I wouldn't have to resort to this as I'm impatient and don't want to be without my phone for that long lol).
3. Software issue. Possible fix includes toggling HW overlays and/or GPU rendering.
Here's what I did:
Took the phone apart completely, made sure there was no visible moisture anywhere (there wasn't). Intermittently blew the phone (from the back and front, while it was disassembled) with warm air from a blow dryer. Left it alone, disassembled, for about 30 minutes.
Put the phone back together, booted up, immediately went to developer Options and (a) disabled HW overlays and (b) DISABLED "Force GPU rendering" (I actually already had it enabled).
BOOM - problem was gone!
So like I said, I'm not sure which of those did the trick - or which problem I had to begin with - but I'd be interested to know if anyone else had similar issues and/or fixes?

I should not have had any condensation at all on my screen when it began. I was using the phone playing with WatchOn and setting it up for my TV, I was messing with it for quite a while and realized after a period I hadn't received texts in a long time (I normally get at least 1 every 10 minutes, I was going on a hour and a half with 0) which I thought was weird so I restarted the phone.
When the phone came back online I did not notice the white dot pressing itself anywhere, but anytime I touched the screen it would immediately know where my finger was and follow it around, but not actually press anything. When I held the power button and the little Shutdown and Restart options came up, if I sat there and just pressed either one of them constantly they would eventually recognize that I pressed something and do that action.
I was also able to get into the homescreen by getting the talk option to come up and backing out of it (The buttons on the bottom of the screen all worked fine) but once in the homescreen I couldn't actually press any buttons regularly so gave up on it.
The guy at the ATT store said he hadn't seen any other complaints about it so I did a factory reset while there (I had already backed up everything with Kies) and when it came back on there seemed to be no problems.
Like I said though I am waiting for a new one anyway, they are backordered at my local store (Should have got a new batch in Friday, not sure where my phone is now) so hopefully the new one I get doesn't have this problem nor the lag problem a lot of people have been getting.

Yeah restarting it did nothing for me, tried many times, took the battery out put it back in all that stuff. The same thing happened with my data, I had a connection that entire time that I was not receiving texts but none of them actually went through which is when the problem began.
What app were you able to get in to to fix it? Would like to know in case the problem happens again when they get me a new one.

Just the stock Phone app. My problem seemed like a software problem more than anything else.
But if you have to restart the phone in order for the digitizer to respond, thats a different story. A swap should fix your issue, since it seems so uncommon.
