Scrambled Screen - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Anyone getting a scrambled screen when pushing the power button to turn the screen on? the scrambled screen is only noticeable for a second or 2. Is it a defective phone? is it something to worry about? It only Happens once in a while.... 1-2 times a day.

I have not experienced this...

Yes. Just happened now. I have my devi e plugged in if that makes a difference. Samsung has a lot to rectify with the first update. A lot

Not to bring back an older thread, but I got a replacement device and have noticed the scrambled screen when unlocking a few times now. It doesn't seem to be happening on a majority of the phones or we would be seeing more threads/posts on this.
Not sure what to do now. Wait for an update that might never come or try to get yet another replacement as I am in my 14 day Window still.

Touch Input Bug?

Just wondering if anyone else has this problem. I'm on 023, but I'm pretty sure it was happening before that as well.
My problem is that the screen often thinks I'm still touching it, when I'm not. For example, I press the delete button for text and it keeps deleting everything I have entered because it keeps holding delete. Another example is the screen getting stuck between home screens, because it believes I'm still touching it, even though I've already finished swiping.
Ye mine does that. Or the touchscreen freezes and the phone just vibrates for 4/5 seconds

Yeah. Exact same thing for me. Except maybe vib lasts longer. Could it be the screen protector? I have an iphone screen protector on top of the factory glued one.

Not sure if is the screen protector as I only have the original on there.
It is rare it happens but I've just been putting it down to a software issue.

Is this issue really common for you guys? Because I text a lot, and I've only had this happen like 2-3 times in the last 2 months...

I send about 2600 text messages per month ( I don't know if you consider that a lot or not) and it has happened I would guess about 10 times. It's just a tad annoying. Especially when you've written a long text or email and it erases half the text before you realize it. LOL..
I get the long vibrate probably 3 or 4 times a week. It's usually when I'm on Meebo, but I've noticed that it usually freezes up like that when the haptic vibrate from the keyboard coincides with an instant message or some other event that triggers vibrate.

Yeah i have this issue every now and then, rather anoying when your mid text!

Waiting time for screen on.

I have tried kj4, kka and sheep rom. All have the annoying long wait after pressing power button intil the screen is lit up. Also tried different CPU governors without result. What is the problem here? And can it be solved?
Is it just me, or do others experience this as a prob?

I've got the same rom, but I don't see the problem you described.... try to reinstall the rom.
ps: you should post this under the thread of your rom, without creating a new one
You may have a defective device.

I have the same problem with my note. I just got mine yesterday. No clue as to what's causing it. I updated my firmware to the latest but left the old kernel so i could keep root access. Had the same problem with both the new and the old firmware.

Just to clarify the issue here:
When the phone is on but screen has been off for a while, the time between pushing pwr button and until the screen lights up is about 1 second, it may not sound much but it just enough to make one press the button once again. Not what i am used to on my previous androids from HTC.
Sent from my GT-N7000 using Tapatalk
Same here. KJ4, stock KKA and sheep KKA. It is annoying indeed...
Probably a user experience thing, you guys who claim to NOT have the issue:
Can you lock the screen and wait for like 10 mins and then on the screen again and time the delay from button press to screen light-up?

Where do you come frome? I mean are u used to Samsung devices or something else?
I am judging this by my 2 previous HTC's whith all kinds of different Roms where I have never seen this.
My thought is that it is on all notes but some people does not see it as a problem but you and me do.

I am having the same issue. Takes 1-2 seconds until the device is fully powered up from standby...
I think I figured out the issue. I disabled weather on the lock screen and now my phone comes straight on. Maybe everyone with the issue can try that and see if it works for them?
Confirmed, getting rid of the weather on the lock screen gets rid of the lag
I'm having the same prob. I'll try removing the weather app and see if that helps.
Great no I cant remember how to remove it. help

This was there even on the s2..
yea, mines also has the same 1-2 sec delay. no weather on lock screen. found it odd, cause i've only had HTC phones so far, and never saw this.
Samsung don't use early_resume in the kernel, that Seems To be more qualcomm Related code.
It's that Code that gives you instant screen resume on the HTC devices et al.
I found this a niggle on the note as well, but have got Used to it,especially compared to amount of work it would take to fix it.

I've never noticed my screen "flicker"; does it flash off and on again or what?
Yeah, please clarify what a flicker is... if it only happened a couple times then it probably is related to the apps or maybe a couple things going on at once.
If it is not a constant, consistent problem and had only happened a couple times then perhaps it isn't a problem at all.

I get the flicker but it's definitely app related.
When using Google music app and going to lock screen, the " widget" sort of flickers and stretches throughout the lock screen
Sent from my Nexus 4 using xda premium
My screen flickered for a good 5 minutes and even a reboot didn't fix it. I think it's hardware related because if it was software a reboot would have fixed it. Could have been a driver glitch too but I'm pretty sure a reboot would've fixed it. My flickered a lot though saw a bunch of vertical lines and discoloration. Idk if that's what you're talking about.

I use Google Music a lot and I've never seen that. I just tried to replicate it and other than the usual CRT off animation I didn't see anything that I would construe as a flicker or flash.
If you hold your device in front of you with the screen on and look beyond it (i.e. over it's shoulder per say) you can see flicker. Works best in a dark room.
No big deal, but it's there.
I think its a big deal ...you spend your money for a working product..these issues need to be addressed..I thought I could trust LG again but dont think I can anymore

This sounds like a refresh rate issue, which would be hardware, yes?

Sounds like one of those magic eye pictures. If you squint at your screen while holding it at a 45-degree angle in a dark room with brightness turned all the way down and jog in place...
I'm not sure how to replicate it based on what you said, but I still don't see any screen flicker.

Mine started flickering like mad today for the first time. I rebooted, but that didn't fix it. I started up a benchmark app and the flickering stopped after the graphics benchmarks ran. I had to RMA my first Nexus 7 with screen issues too, so I'm hoping this is just a software issue
I don't have this issue at all.

Everyone with an s4 watch this

Need some input please. Watch this video that I filmed of my s4 earlier and tell me if your phone does this too.

Occasional home button response delay
Sent from my Galaxy S4
Your definition of Lag is definitely different than my definition. However, the "home" button has a short pause because it is designed that way. It is waiting (just a fraction of a second) to see if you are going to use it for it's double tap option or not. Disable this feature (you can search for how) and that very little delay should go away.

change S-Voice setting to not open via home key. home button response delay solved.
You did a 10 minute video for that???? I believe when you say you have OCD. I suggest you to seek professional help, and not from Samsung support
I agree there's nothing wrong with your phone.. But they're might be something wrong with you if a .01 millisecond delay bothers you to the point of making a 10 minute video and rambling on and on about it. I would try and get laid if I were you and stop worrying about the phones home button.. Not that big of a deal

Thank goodness for fast forward or that would have been a painful 10 minutes.
You should all kinds of weirdness with your launcher - how about going back to stock 100% first. But from what I see things are fine. Maybe the mechanical home button is slower then the touchscreen. You could always return it for an iPhone.
Hahahahaha is this guy serious
Sent from my SAMSUNG-SGH-I337 using xda premium
Limiting the process to four will negatively impact your performance.
More ram usage does not mean more battery usage, in fact it should usually save battery because the applications are already loaded in ram when you go to use them. If you are constantly killing them you'll have to reload from nand flash and back into ram.
Also you should probably try to make shorter videos
Do you have any idea why when I have maybe 5 apps in my recent list my home button response has a slight delay but then if I clear all recent the home button response is basically instant?
Sent from my Galaxy S4
I actually went to at&t yesterday to compare mine to the display models and the home button response was exactly the same, until I started loading multiple apps then mine was a tad bit slower. You guys might think this is ridiculous but I'm just trying to make sure that I don't have a defective device. I have like 6 more days to return it to Verizon if i feel I do.
Sent from my Galaxy S4
If you feel your device is a defect. Just go get an exchange. Let us know how your second device is doing.

your not crazy, the lag is def there. however, it is designed to be like that, so there will be no changing it. just ignore these trolls, everyone loves the opportunity to come out from the shadows to spew spite all over the newbs and repeat posters.
Well I took the s4 back and they exchanged it for another. Seems to be working much better.

Anyone else sometimes experience touches not registering on the touchscreen?

Randomly it seems, when I tap on the touchscreen on my new N7 2013, nothing happens, and I have to repeat the process several times before my touches are registered.
Does anyone else have this problem?

See my thread titled " Another touch issue, with reproducible steps".
Go into developer options and enable "Show touches" and "Pointer location"
If you see your touches registering but the app isn't responding, it is probably a problem with the app. If you see random stuff on the screen, probably a problem with the digitizer or digitizer in combination with the driver/software in this release.
Ive experienced this a few times and it seems to be a software /hardware interface issue with particular custom rom builds ive installed. I know the touchscreen hardware itself was fine when I forced reboot into recovery and the touchscreen worked as normal in custom recovery.

I wouldn't. If you had a Verizon Galaxy Nexus when it came out, you'll remember that it had the same issue with certain points on the screen (lower right hand corner) when using multi-touch applications. The entire screen would either stop seeing input or start going erratic and creating faulty inputs that weren't happening. It isn't a hardware issue, proven by some users experiencing it and some not. The only time I've experienced it is in the Netflix application while trying to choose a show to watch. I re-boot the application and viola, no more issue. Some in this thread even are stating that they only see the problem sometimes after getting the 4.3 update.
In short, it's software and not hardware.
Same issue when not touching with both hands somehow (like if the tablet is flat on a table).

Haven't had a problem with mine. I just got it today, and it's worked like a charm. I bought mine from Gamestop if that helps any.
