[Q] Random Touch Screen Issues

hey guys, I´ve been having some strange behavior on my M2 lately, everything was normal till last week but now the phone started registering random inputs on all over the screen... its like I am touching the screen madly... I´ve already tried flashing the retail brazil SBF and everything still the same... I can´t even answer the phone straight!!!
any ideas? maybe my digitizer has gone crazy...

Take a look at this vid. It's mine. It is happening when i'm scrolling fast. I think I will send it to a service.

I get this when my phone is on the lockscreen connected to my pc.

this happened to me a few times before. once was when i typed a really long email using my keyboard. when i shut the qwerty it started behaving crazy. a few other times was also after i used the keyboard.
then i realized something in common. the problem only occurred when i had 'words' running in the background. i uninstalled 'words' and i have never had the problem since
perhaps u have a really buggy software. try uninstalling one of ur buggy softwares and u would be grand.
if u cant locate the buggy software, turn off the screen (short press of power button), turn it on again, and unlock, and things should be back to normal

well... it look like I gonna have to send it to service too... I´ve already wiped it clean... I´ve done a clean flash of the brazil retail SBF and everything is the same... random issues all over... bad luck right?
thanks for the support guys!

I have not experienced this problem...maybe because I'm running stock ROM?

KF3 Firmware out on KIES

I am not sure if there is a thread already out for this as i couldn't find one on search.
I am a SGS II user in India and i just got a KIES notice that a firmware upgrade is available to KF3.
Is this the same one as what was release on samfirware?

Firmware had already been posted in the firmware thread in the dev forum.

As for changes, I have noticed the following till now...
1) The image for background effect, in the display settings has changed
2) The battery life seems to have improved significantly
3) Lock screen display wake lag seems to have come in now
4) Background themes in messaging is no longer there
Will keep you posted as soon as i notice more changes.
Do share anything you guys find too...

i jus tried updating my SGS II to KF3 via KIES it downloaded the update and after decryption of binary data the mobile display is staying on the green android logo and below it downloading ...
WHt do i do .. pls help

The update process gets stuck if KIES is not able to connect to your phone properly. Usually this ends with a popup message saying Update mode couldn't be activated or something like that.
If you do find a blue progress bar increasing slowly below the green android then all is fine, just wait. But if The process is stuck at 0% or an error comes up. Then you can try again by doing a hard reset of your phone and trying to run the update process again. Do not use the recover firmware option in Kies at this moment. The hard reset is necessary as third party launchers and other apps sometimes interfere in the connection to Kies.
To, get out of the green Android download screen and do whatever is stated above, simply remove the battery briefly and start your phone again.
Hope this was helpful. The information i provided is just based on my experience, correct me if i am wrong...

Thanks for your feedback. But what do you mean by No.3, Lock Screen wake up lag seems to have come in? It was there in KE8 also.
And can you test if the Noise Cancellation On/Off option is included while pressing the Menu key in a voice call? It is not here in KE8.

Yuppp, I know many people faced the lock screen lag issue even in KE8/KE7 but mysteriously, I never had the issue! Where as in KF3, I now get a delay even though its just a couple of seconds.
As for the noise cancellation option during the call, both, the call screen icon as well as the menu option are still absent. :-(

[Q] Answer sliding lag!

Hello,I have the same lag?
Anyone else have noticed this?

Yes, I've got the same problem. It took so long the other day that I missed the call completely.

anyone have an solution?

First thing I would do is a hard reset - A pain I know, but doing so you can check whether it is potentially a Hardware issue with multitouch/touch etc.
Once you've done that, if it's still exhibiting the same behaviour check your screen behaviour on touch reactions on normal day-to-day use. There may actually be an app for it. (the Note 3 suffered some touch problems, not saying the S5 has them but have to check to be sure) .
If it is deemed a software glitch and a reset fixes it then you should be OK. - However if it's a touch screen bug I'd suggest returning/swapping it.
I'm more inclined to believe it's a software glitch, and a factory reset will indeed solve the problem.

Oke,thanks

Same issue! Did a factory reset but didn't help. Send it to local service center, they keep telling me there is no issue with the phone and that when it happens I should record a video as evidence of the problem. So much so Samsung warranty! Plus I have encountered ransom reboots when answering the phone.
Totally unhappy with S5. It is terrible. S4 and S3 were very stable.

i did noticed that too..
on mine if you put directly your finger in the circle and drag it works 1st try..
i still didnt have time to hard reset to be sure..

I noticed this too. I find that you have to hold your finger on the green answer and slide slowly. It's definitely a software problem that will hopefully be fixed in an update.
Factory reset makes no difference as done this for another problem I was having.

Don't suppose anyone has found a solution to this yet? Or any alternatives to the stock dialer that might perform better?
I also get a lag between selecting a text field and the keyboard popping up which is very frustrating. Had expected more from a brand new phone

I had this problem at first as well, but after the latest update it fortunately disappeared, I did a full wipe as well.

Same problem here! Partially solved with enabling home button to accept calls....

Same here....its a pain in the ass ?

I disabled the lockscreen animation and that helped making the device more snappy. Here are some more usefull tips http://phandroid.com/2014/04/25/samsung-galaxy-s5-first-14-things-to-do/.

I also have this lag when I'm trying to respond. It only woks on the 2nd attempt.

There's definitely a knack to answering a call, which can be quite annoying. Cannot understand why they didn't just leave it alone. Would rather answer my calls with a quick swipe to the right.

Galaxy S5 black screen upon wake up

I would reflash the stock rom you have atm and data factory reset afterwards or try a data factory reset first and see if that fixes your issue.

Known bug. Supposedly fixed in recent firmware updates. More details in existing threads.
Or simply circumvent the issue entirely by upgrading to a good third party screen saver.
If you're ambitious, you could also try the following edit, which may help.
Make a backup first, then try editing build.prop
Code:
mot.proximity.delay=0
ro.lge.proximity.delay=25
.

I have the same issue... do you still get this issue? For me, sometimes, the screen does not wake up only the capacitive keys... I have to press the power button again to turn it off and then press power again to turn it on.

me too
Hi,
I'm having the same problem.
It was intermittent for a short while and a battery pull would fix it, now it's permanent.
I get capacitive buttons, I can boot into recovery or download.
I can hear touches on the screen and the annoying at$t boot sound is back since I used Odin to reflash to stock.
I think I have to take this phone to a service center and see if they will exchange it.
I'm worried that there may be traces of towelroot but from the thread that provides stock firmware and instructions for Odin it would seem that I'm good.
Has anyone had any luck with this issue or have any other tips to try?
I'm bummed because I just applied a glass protector and it looks like I'll have to get another.
Not to mention having to drive to the center.
Thanks.

With the new 1.100 motherboard version the problem is solved. It's a hardware defect. Maybe it will be fixed in next fw versions with some voltage or timing setting changes but a mobo change will definitely solve it.

For the record:
The at$t service center reflashed my phone and the screen works again.
IDK why flashing stock with odin did not work for me.
I can see from the post above mine that the problem might come back, I'll insist on a replacement if it does.

still getting the issue but for me I just need to press power 3 times for it to wake up; no need to remove battery

[Q] phone does not wake up

Sometimes, when i try to wakeup my phone using home or power button, the capacitive keys light up but the screen is black.. I have to press power button to "sleep" and wake it up again... any idea? It was like this since I got it.... I updated recently and the problem still persists... it's not a big deal but a bit annoying at times.

It may be due to firmware bug or some installed app.
You didn't tell what rom you are using (stock or custom). And also check for installed apps that you suspect.

It's a hardware defect. Mine was like this too since 11th april. After changing the motherboard to the newer, 1.1100 version, the problem is competeley gone away. It's waking up every time correctly.
We had a topic about this earlier...

Hardware defect? Are you sure? I dont have a warranty. Bought it abroad. I was hoping it was just a software glitch. I am on stock unrooted
