Touchscreen and buttons issue

Hi there, I have some problems with my Kaiser - strange behavior of touch screen and buttons - sometimes the touch screen becomes less sensitive and needs more preasure to take effect. The buttons - especialy the green phone button does not work somethimes - this effect disapears after few seconds or several times pressing the button ...
Does some one have idea if this is due of some software bugs or need to repair the hardware.
Will appreciate any opinion.
Thanks in advance!

Stock ROM?
Hard-Spl?
Etc....
Always good to provide as much info as possible for people to help.

I have bought the device hardspl-ed flashed with cooked rom. Then I have installed the stock rom - last official from htc site.

Funnily enough, I've noticed this with the screen in the past week myself.
I'm using the stock ROM.
I assumed that the device was busy trying to do too many things at once, but when I checked, I wasn't running any other applications.....

[Q] Galaxy S Display Rotated Upside Down. Need Assistance :(

Hi everyone...
I've been having problems with my Galaxy S since yesterday. After upgrading to XXJPM my display is rotated 180 degrees (completely upside down). Strangely enough, the touch interface seems to be working just fine.
For example, the "Phone" icon is supposed to be on the bottom-left of the screen. It is now displayed on the top-right corner (again, upside down) but in order to activate it I still have to touch the bottom-left corner right on the icon's original position.
The display is also rotated 180 degrees if I enter recovery or download mode, but the volume up-down buttons still function as is. There are times when the display will appear normal for a few seconds before rotating itself 180 degrees again.
I followed the installation steps to the letter, did everything properly, I even searched just in case other users had similar issues, but I still haven't found a fix yet (really sorry if I missed similar threads). I also tried calibrating the g-sensor, but that didn't solve the problem.
Auto-rotate works perfectly, but the screen is still upside down no matter which way I rotate the handset. The same goes for when auto-rotate is off.
Any thought will be highly appreciated. I'm also willing to make a small donation if necessary. I'm desperate for a solution

I did, but that didn't solve the problem. I think it has something to do with the bootloader since during startup the screen would show the normal Galaxy S logo correctly for about one second and then the display is rotated. Even the download/recovery interface is flipped.

The Good and the bad
Good news first: you are not the only one have this problem.
I have same problem after updated Nordic v. Froyo.
Bad one is I haven't got a clue how to sole the problem.
Let't belive ours has special talent which can jump twice more that ordinary ones.

try reflashing with one of the roms that has a bootloader included. search around not all do.. i know the jh2 for i9000m has bootloader..

Tried this, didn't work too. I also tried Tayutama Edition rom, actually it helps a bit. After finishing the sdcard scanning routine the screen would work just fine for quite a while before going straight back to being rotated. It is also still upside down during the entire boot process.

Found another interesting discovery. Still using Tayutama firmware, if I switch the Power-Saving Mode from Display settings off and on, the display will be reverted back to normal.
I wonder what's causing this issue in the first place...

Tried another fresh rom, still no improvement...
I attached a picture showing how the screen is upside down even in download mode. Notice how the USB port and the download mode triangle just don't match.
Any further advice would be highly appreciated

Solved Mine!
Make sure Galaxy lie FLAT(back of galaxy isn't flat)
Setting-Display-calibrate
Mine worked that way hope yours too.
Now landscape to potrate turn like cream
but added bonus is landscape turn either ways .
what a great addition.

I'm afraid that doesn't work for me
I'm glad you fixed your Galaxy S though. Quick question: did you have the screen upside down during the Galaxy S logo animation on startup?

It seems diffren kind problem
I am sorry that my solution did not work for you.
Mine did work few hours after down load Froyo.
Then problem began.
Have you tried factory reset then calibration?

Yes, I tried that and it didn't work.
Still trying different solutions right now, hope I can get a good solution soon

I have another Galaxy S in hand. The broken one still has its screen upside down. I was wondering if I can backup the bootloader and ROM of this new Galaxy S with the system working correctly to the broken one. Will that be possible?
As always, inputs are welcomed

Thanks wonbad!

Thanks! I had also problems with auto rotation, did even factory reset but did not start to work until made calibration you mentioned.

I've tried virtually anything to get the display fixed, including doing a complete rom backup of a healthy Galaxy S, and the display is still rotated. I think it really is a bootloader problem.
I took it to Samsung service center here in Bali. They said they can fix it, but they won't because I got the device in UK and I need to take it to a service center in the UK to get it fixed. Crazy...

A quick Note
==========
Just to make it clear, for any future reference, display rotation if shown when it is powered off and charging and also while booting, this is most probably a hardware issue, this can ONLy be achieved by replacing the LCD (or doing a hardware repair of the LCD) it has nothing to do with sensors or software.
Thanks.

[Q] Screen not working propperly

Hey guys, i'm new in these boards, so if this is not the right way to post or the right place to ask this question, sorry!!
I have a problem with my Incredible S; There are portions of the touch screen that don't respond propperly, the most alarming one, the section where the phone-apps-personalize buttons are (mostly because all buttons are always on that portion of the screen). The other one is the section where the 'install' market button is. These sections are about 0,5cm, so the whole line doesn't work.
The screen is in perfect conditions; no scratches, not broken glass, no dirt under the glass, no water, nothing. NOTHING. Phone is barelly 4 months old; bought it factory unlocked.
I tried rooting the cell, flashing clockwork mod recovery and installing several roms to test if it was a software problem; i noticed roms with ICS and 4.0 Sense don't work at all, while other oldies, like CoreDroid with Gingerbread still won't work perfectly but it works well enough to allow me to finish the initial setup (the 'next' button is in the area that doesn't work propperly, and no, i can't flip the phone 'cause those buttons don't flip on those screens). Typing is a pain in the behind though; it's seriously a nightmare.
The problem is pretty much the same as the one on this video on youtube which link i can't post yet (but you can easily find under htc incredible, eh title, tags incredible s touch screen fail not working).
I also tried with the htc calibrating tool, and some others... no luck.
I've seen that many people have the same problem, yet i haven't found any solutions... I want to hear some opinions, if anyone has any, before i decide taking it to repair and changing a perfectly fine (to the eye) touch screen.
Thanks in advance!

If after you have touch problems you need to either:
A. Replace screen and digitizer .
B. Pay to replace screen and digitizer.

Thanks for the suggestion; i installed and ran the app, and the results were pretty much the same; those areas are blank. If i try running my finger through them, it recognizes it as if two different fingers are running around that area but not over it.
What drives me insane is that i'm currently with the coredroid rom, and those sections *SOMETIMES* react (at least well enough so i can finish the setup on the phone and start actually using it). On the opposite, when i'm using any based ICS rom, they don't react at all. That makes me wonder, is it really a physical problem? or what?

I have a solid feeling that your digitizer is malfunctioning, however I'm no expert but I don't believe it should vary rom to rom. Maybe the touch sensitivity in coredroid is turned way up and it allows you to press the buttons from outside the area.
Sent from my Incredible S using xda premium

Heh, i know, i'm pretty sure it shouldn't vary, but it sorta does... what you mentioned about the enhanced sensitivity on the coredroid rom makes sense though; i tested about 5 roms already and it's the only one so far that sometimes works.
I'll try to buy a digitalizer screen over the net on Amazon or somewhere else and have it shipped here; otherwise i'll just have to wait 'till i go to Ontario in a few months.
Thanks again!~

Touch screen responsiveness issue

Hi there,
I'm having a problem with my touch screen. It works fine most of the time, except, when I tap the same area many times very quickly (like when I'm backspacing a whole message), that par of the touch screen eventually becomes unresponsive. It becomes responsive again once I turn the screen lock on and off again (the top button). I've read a few threads around with very similar problems (not on here I don't think).
I replaced the touch screen a week ago, but I've only noticed this today, so I'm not sure whether or not it's related.
I'm just running standard LG software and haven't put any third party stuff on there (apart from apps). I've done a full reset using the update utility, and using the hidden menu, but this did not fix the problem.
Here's some details about my phone:
Model: LG-P970
Android Version: 2.3.4
Kernel Version: 2.6.35
Build Number: GRJ22
Software Version: LG-P970-V20C
Please let me know if I should provide any more information. I'm just interested in knowing whether it's a problem with the touch screen, or the phone's software.
Also, I'm new to forums and what-not, so if I'm doing anything wrong, let me know!.
Ok, I've realised this is in the wrong category. Was bound to have done something wrong - won't happen again!
Thanks

Hi there,
Tell me please, does the same happen on the touch keys (menu, home, back, search)?
Also, do you have any screen protector applied?

I have said this few times in other posts..iIts a strange bug, like the touch being lost.
Its fixed easy by locking the phone, thus shutting down the screeen and touch sensor. After few seconds unlock the phone and check if it is solved, or do the process again.

Thanks
Hi Guys,
Thanks for the replies, sorry I've been away for a while.
It doesn't tend to happen on the home, back, etc, keys. It tends to happen mostly near where the backspace key on the keyboard is. It happens in other places, but it takes a lot more to trigger it to happen in the other places. (by trigger, I mean if you tap the same spot heaps when writing a message it starts to happen).
Also, yes, I've applied a screen protector. The screen protector got put on about 10 hours after the new screen, but I can't for the life of me remember whether or not it was doing it without the screen protector.
Yes, locking and unlocking the phone does fix the problem, but it's a bit of a pain doing this a few times when writing a long message.
I'd really like to know if anyone can tell me whether replacing the touchscreen will solve the problem, or if its to do with other hardware/software. I've since started using the CM roms and it's still an issue.
Cheers.

I have a touch-screen problem with my LG P970 (CM-10 stable)
Hi,
I have been using my lg p970 for more than 2 yrs however when I installed cm10 stable i my phone it works fine for some time then touch-screen does not response properly. When I touch in one corner response comes from other corner, especially while typing when I press one key 2-3 other keys are also pressed even though the keys which are press not even close to each other. I have install another keyboard from market this has reduce some misbehavior.
Please any one has a 100% solution to this problem please reply.
Thank You.

My main reason for reverting back to 2.3.4. Usually occurred when receiving a call; I couldn't answer or reboot the phone. I had to pull the battery every time.
I'm not aware of any fix, save reverting back to a GB ROM.

i think its hardware issue,,if i press and hold a little while on upper screen (right beside lg logo) touch screen became normal again. but sometimes need to hold on there when touch not work again. a member on this forum call it a flex issue of the touchscreen.
anyone know how much cost to replace it with new flex to fix this issue?

If it works with 2.3.4 and not other versions, it's a ROM issue. Changing the screens probably won't help.
This loss of touch was reported by many users, and it's always a 4.0.4+ problem. Something software-wise is crashing, or there's a driver bug.

[Q] samsung galaxy i9000 CM speaker problem

hey there.
i´m using an i9000 with the recent stable fishears cyanogen mod running on it. (see http://forum.xda-developers.com/showthread.php?p=39171569#post39171569 for more technical info)
i was able to listen to music (with the apollo music player that came with the rom) without trouble via the speakers - but after i aquired a headset yesterdsay and plugged it in for a test it worked just fine - only problem was: the phone refused to afterwards play music via speakers after unplugging the headset again - i had to reboot the phone for that to work again. i didnt find any option to choose the output method. am i just blind or is there in fact something missing?
i dont really know if that problem is already known to you guys - so please excuse me if i overlooked an existing thread about this.
also - my english isnt that well used - feel free to ask if you dont understand what i´m writing...
anyway - thx for your efforts - its greatly appreciated.

Have you tried installing other rom to check if issue is with your phone hardware...

i dont really want mess with the rom if not absulutely necessary - there´s always a chance of bricking the phone with such actions...

I have flashed i9000 thousands of times however never had any issue with flashing

and while I´m grateful for your response you could work a bit at making it more useful...
so - is this bug known or not? I´m pretty sure that my phone hardware is okay - everything i checked makes it look like a software failure...

No....I dont think its a bug I have never came across such thing.

Happened to me I was flashing roms when i got my phone and speaker just stopped working. Im pretty sure its the speaker and I heard its a common problem on the i9000. New one is pretty cheap on ebay and the speaker is pretty easy to replace. BUT DONT TAKE MY WORD FOR IT. Try a different rom and if it still doesnt work replace the speaker. Its a pretty easy and cheap repair Good Luck

Let's bring this to life!
I have an i9000M and after installing slimkat 4.4.2 (slimbean) the earpiece stopped working, also the home button. I'll switch ROMs to see. Maybe is the kernel? When I enter recovery (CWM 6.0.x.x) and go to test keys, the home button didn't log.

I downloaded Semaphore CWM (from semaphore's website) and now all works.
I was talking about the test key option in the Advanced Menu in CWM (you press all keys and it shows if they work, and what command they are assign to do) Volume Up was mapped as Volume Down and vice versa, Back was Home and Home didn't work at all.
Now all works!
