funny screen problem?

Hi everyone,
I'm experiencing a very weird problem, with my Trinity (actually a p3600i).
When I'm using my thumb or fingers to type on any SIP, sometimes the start button is pressed even though I'm no where near the start button!
I'm not sure if it's happened when NOT using SIP.
I've noticed that it only happens when using my thumb/fingers. If I use my nails to type the problem never happens. Same when using the stylus, no problems...
Anyone know what is going on here? It can be very annoying sometimes.
Thanks for reading!

OK I just made it happen when just in the today screen.
Doesn't just happen when using any SIP...
Happens when I'm tapping in the bottom left region of the screen in portrait mode.

you are not alone
have the same problem, occurs couple of times a day, and as you noticed when using fingers. we are not the only ones, many (really!) trininty users report the same problem. finally it may result in widely known problem related to flickering start menu button and irreactive touchscreen.
i noticed one more thing: when you disable sound for screen taps from sounds and notifications menu the erratic reactoin seems to go away, not completely, though because i still manage to cause false start menu activation by chaotic screen tapping in phone mode.

read this topic, sorry to disappoint you but imho this is our nearest future

looks like i will need to send it to them for repairs
and nothing ever returns back the same, when it goes to get repaired

Touch Screen too sensitive

Has anyone else had the issue where you can press down on the screen, a tool bar or something and the screen starts to shake or the selector starts to auto select things. I get this a lot and typing is often very hard because it randomly selecting things when i am typing on the keypad.
I have seen it once when i put the phone down go through random menus, is this a fault or just normal due to sensitivity?

Hi
I've had the same problem several times with both stock rom and cooked.
I turn it off, wipe the screen and it will usually revert to working properly.

Most would say it's a fault unfortunately. Personally I've returned mine for a replacement after a 'repair' which fitted a new screen made the problem worse.
See this thread.

Back Button Problem

This might be a relatively small problem but it can be a little annoying. The back button (right side of the menu button) seems to be a little less responsive and 'smaller' than the options button (left side of the menu button).
By smaller I mean I need to click it exactly at the right spot and the button reponsive 'area' seems to be very small compare to option button which seems to take up most of the left side allocated to it.
I am not sure if this is intented or some kind of software/hardware fault?
I read about upgrading touchpad firmware through *#*#2663#*#* but there are reports than this could brake the buttons completly.
If anyone has any information it will be greatly appreciated.
P.S phone is not rooted and I bought it from vodafone Ireland.

there are a few threads on the hardware buttons not working correctly try the search.
I found one about the back button, not a lot of info though.

I have the same issue but also to another extent. Mine has an issue where sometimes it will double tap when I only press it once. This can get annoying. I do have a screen protector on and I'm not sure if that has anything to do with it.

Same thing happens to me ... but Its kinda rare(I am not using a screen protector). Does anyone know a solution? should updating firmware fix this?
I am thinking about asking for a replacement.

Replace it, same problem with my first unit, 20% of the presses didn't register

I thought it was just me with the double tap when i press it once lol. Grrr its annoying man! :[email protected]

So the only way to fix it is to replace it?

I would imagine someone can make a mod to the touchkeys for like a certain millisecond delay between presses to fix the double tap. People have patched hardware keyboards for stuff similar to that.
As far as the non-registering presses, that might have something to do with delay too. A smart developer would have to try and look at it though I'm just guessing here.
I haven't noticed the non-registered presses in a while, not sure if it went away with a new kernel or if I just got used to how to press it to make it work. The double tap happens more often to me now lol.

Happened to me on my first unit, back button was only responding about 50-60% of the time, on the 2nd phone back button was extremely sensitive ( as sensitive as the SAMOLED screen which is a huge plus) 3rd phone seems "normal"

Galaxy S2 back button getting pressed twice on a single press.
When I am in 2nd/3rd level screen of an app, back and menu button lights go off(but screen is on). While pressing back button sometimes it's going back 2 levels with one, single press! As if I have pressed it twice. It doesn't happen always though.
Is there any fix for this?
PS: I am using a screen protector. Will remove it and see if that's the culprit or not.

u shud b thankful mate..my home butoon stopped responding at all

Hi,
Sorry to hear that.
But how did it happen? And how old is your phone? It must be still under warranty. Did you try taking it to the service center?

Back button problem sgs 2
I was also having this annoying problem.....searched over XDA....and found some tricky (fishy) codes for updating touch firmware.....which may end up braking those keys....so i stayed away from those tricks..
i googled again and found one method which finally worked for me
To get sgs2 into sleep use power button...nd for waking up use home (centre) button...this worked for me

Odp: Back Button Problem
Sorry for digging it up. I have the same issue, sometimes back button is acting like it was tapped twice. Is there any sofware solution instead of replace any parts?

Windows button not always responding?

Hello! Just bought an Optimus 7! Really good phone for the price!
But i got one problem! When im going to turn on the phone with the windows button its sometimes not responding!
Somebody else got this problem?

Yes. Happens to me all the time, but I always use the power button to turn on the screen so it doesn't bother me that much...

Sounds like a known issue.

Same here. It must be a software bug because the button is always working when the phone is unlocked.

If you still hold for a while it works

One reason for the screen not turning on is that you may be blocking the proximity sensor at the top left of the phone. The reason behind that is probably to avoid turning on the screen when the phone is e.g. in a pocket.

for me the start button for screen unlock always works, but many times screen is unlocked and all black, the systems listen to the touch input but doesnt show nothing at all....it happens very often usually when the phone is hot...

Home button problem

I have a problem with my S8. After locking my phone it randomly vibrates and turns screen back on asking to unlock (enter passcode or scan fingerprint). Sometimes this happens right after locking and other times after 5 seconds when my phone is already placed on the table. When I unlock the phone there is no notification. I can't seem to find out whats causing this. This is not always (but most of the time) happening though, its really random.
Checked internet. Checked Reddit. No apps enabled in accessibility. Smart Alert disabled.
Its driving me nuts, please help out.
EDIT: When removing passcode the phone unlocks itself to the lockscreen. Just happened after 15 seconds when laying flat on the table. Should I leave my house??? haha
EDIT2: Seems like the homebutton is registering presses. When 'Unlock with homebutton' is on it go's straight to the homescreen when above happens and when its off it turns on and just shows lockscreen. Really strange..

Seems you got faulty unit, ask to return.

Don't think so because it only happens when the phone is locked. When the phone is unlocked it behaves normal..
Thanks for the suggestion though

Actually, this is a HUGE issue IMO and abnormal behavior of the phone, which is subjet to return.
You should be straightforward in your decision or get used to the issue.

I'm tryning to say that I don't think this is a hardware issue because than it would be all the time, must be software related but can't seem to find out whats causing this.

F*CK, I think I found it. I disabled AOD, with it enabled I don't seem to have this issue.. :/

S8 Unlock problem
Im having the same problem. I unlock using the pressure sensitive home button. After locking and unlocking 3 to 4 times the home button does not respond "only on the aod screen". Then suddenly it unlocks and when I lock the screen again the phone vibrates and unlocks the screen itself
Plz help me out

I'm having the same problem. Sensitivity changes randomly. Sometimes it doesn't seem to recognize presses and sometimes it recognizes them even when I'm not touching that area. All this happens when screen is locked. AOD disabled. Sensitivity to 2 (close to very sensitive)

I have the same issue .. AOD and the rest are off! Case was taken off also. What's going on !? I don't now what to do with this... ? Mayby the best option is to change it for iphone? ;((((

Having exactly the same, however samsung technician was unable to replicate it for a whole day and they sent it back to me without any repair... Swap is also not an option as samsung will test phone on their side anyway and in case it's "good" they will send back same unit.
Issue is really random and sometimes it doesn't occure for over an hour. Then it starts vibrating and waking up after touching screen in top or middle area couple of times (screen off, AOD off, no case, no screen protector), multiple vibrations after pressing "home" button or delayed vibration.
Other reports are on reddit (pm me for link) or different xda thread forum.xda-developers.com/galaxy-s8/help/hard-press-home-issue-t3597004/page4
Anyone able to record his issue to compare with others?

Same problem here....the hard press home button don't work sometimes and vibrate 3 or 4 time after press the button. I think is hardware problem, i have reflash the firmware with odin but no lock.

Did you send the phone to Samsung assistance? And does the same problem? [emoji21]
Inviato dal mio NX531J utilizzando Tapatalk

I went to Samsung Premium Service and left my S8 (Exynos one) for 2 working days.
Sometimes when I press home button it vibrates once or with significant delay and then when you touch screen anywhere else (top, middle, edges) it vibrates again and wakes screen up. It looks like it cannot register/release pressure sensor correctly. Since they were not able to replicate this error they decided not to touch hardware at all, therefore just reflashed it and calibrated.
I'm getting this 2 or 3 times this every 15min, but it's hard to record, because when I start recording it's already working properly... Have you managed to record your issue to compare with other users having similar symptoms?

The same problem with my phone....unfortunately i don't have any record of issue. I think is a touchscreen problem

My pressure sensitive home button has a mind of its own like it works or sometimes doesn't register as a press then sometimes when I try press harder or softer it goes mad and registers lots of presses. Sometimes it just works properly though. Should I return it quick or is it just normal if the screen has to be cleaned or something?

I have same problem, i owe factory unlocked s8 created for caucasus region. my home button makes me crazy, even now when i was writing this, just picked my s8, i pressed hard on home button, on the screen off (I've enabled always on display) and no kind of vibration, than touched back button and it vibrated. So sometimes it vibrates 3-4 times when i hard press only one time, sometimes it's giving me very late vibration, sometimes i also think that i get notification and nothing is there. yesterday it gave me two vibration, during facebook scroll. i'm a big fan of samsung but, this s8 has too many hidden problems, bugs and luggs.
isn't it possible guys that in the next software update it will be solved?

Same problem here. I think there is another thread with this issue btw?
It could very well be a widespread issue but a lot of people might not even be aware of it because not everybody's using hard press preferring other ways to unlock/wake the phone.

Same problem

Me too ,its happend just wgen the phone is locked, when i hard press home button sometimes it gave me little vibration and when relased the correct vibration or other times it gave me 4 vibration.
It could be software broblem because when the phone is unlocked doesent happend and
too many people here have this problem

U won't find out when it will miss vibration or any other bug or lugg. I'm testing and testing, even i pushing home button half an hour without resting and there were no kind of bug. I think that, than when there is no too much free ram and also when phone is hot, also U have many apps minimized and u lock the screen. And at once u push hard on home button. It will fail vibration and if you observe during screen unlock, animation will stuck. It's opening bit-by-bit. Looks like very low FPS. So this 3d touch failure makes phone work luggy.
P.S. sometimes phone is cold, with much free ram and same happens((.
Also when phone is locked for long time. When you press hard on home button on screen off (with always on display) it will miss the first pushing.
Sometimes if it fails vibration, it continues doing this for minutes, even phone restart will not solve the problem.
There is something wrong. This phone has ram managment problem, there is something strange. This device is a real rocket but it isn't well optimized.
I hope Samsung will fix this bugs in the next software update, otherwise i think i will go to iOS. Just i need smooth animations, smooth app open/close, without stucking. Without luggy, without bugs.
Whith this problems this really fantastic devise is nothing.
P.S. i'm a big fan of samsung. Have had many iphone, and thinking to return there.
Sorry for my english.
