the firs link is the only one with the same problems im having, touch screen works but not after it goes on standby or if the phone go on standby by it self and i press any other bottom (not the end bottom) it will still works
everyone thinks is a hardware thing but how is the touch screen actually working for me? not like second link where the touch don't work at all
mine works but if i press the end key to make it go standby and press it again it become unresponsive, but if it goes to stand by by itself and i press any other key it will still works
well.... i guess we'll never know
probably my hd2 will go to the broken i might use it to fix any other thing drawer
Aaah.. FML

Galaxy S2 ULTRA LAG on wake up

Hello I have a 9100 international version, and this is not your usual 1-2 seconds lag on wake. My phone (well, my friend's) takes around 10 seconds to wake. Not exactly wake but for the display to show, because when I press the home key or power key, the soft keys light up and the phone vibrates to the touch, the screen is also responsive to touch while the screen is off.
All this started after I flashed paranoid android into it, but after trying multiple roms, the issue is exactly the same. I also flashed a pit file to repartition the phone to have more storage for apps and it worked. I mean the phone works flawlessly except for this particular issue of the screen not turning on fast enough, even though the touchscreen seems to be responsive.
Ill flash stock back to it and give it a try. In the meanwhile, any one else have had this issue?
Try Neatrom 6.4 is a stock based with more feautures and battery friendly. Yeah i faced this issue one time, in neatrom 6.4 i never have this issue.

Capactive Touch buttons on Galaxy S2 doesNOT dim or Times out automatically. HELP !!!

The Capactive Touch buttons on Galaxy S2 does NOT dim or goes out automatically & rather radiates a strong touch screen light,even after the "Touch Key Light duration is altered to various intervals (1.5 sec or 6sec)" . The two Touch light only goes off with the Phone's Screen timeout or manually (pressing the power button) .
It was never like this till last week when the Octa-LCD inside my SGS2 broke & today when i changed the complete display assembly of the SGS2, i got to take note of this peculiar & harassing problem only now..which is eating up my mind.What's happening &why? Was the Screen replacement Not correctly carried out (done at my Authorised Samsung Service Centre) HARDWARE problem or is it due to any Software issues? (Samsung Service Centre did say that they did no software job,only just a screen replacement i.e a Hardware job on my SGS2)
i'm Rooted, on JB 4.1.2, Stock Rom with Siyah Kernel !
Though Samsung have offered me to replace my screen for a second time in a few days ( they dont have any more stock of the SGS2 scrren at this branch), but i myself NOT Sure..what's causing the problem ? (Everything in my SGS2 is running fine except this stressful quirk which was Not there before).
.'m at a fix ,please Help me with your advices ASAP !!!!
Have you tried flashing a different kernel like Apolo kernel 4.15b or try an older version of siyah kernel 6.0beta4.
I don't really think it is software problem if it was working perfectly fine before.
HELP my SGS2 !
Thanks @gsstudios for the good advice !
...but is there any app/mod for the SGS2 that can control the capacitive buttons light settings, other than the system settings for the SGS2 like the one> Galaxy Button Lights https://play.google.com/store/apps/details?id=com.notquiteinsane.galaxybuttonlights&hl=en (works for SGS6 but not in SGS2)
I'm Not quite a Flashholic,neither do i get much time to tinker around ..so any other quicker way,except flashing a different rom, to control the light settings?
* 1 important thing Maybe ...when my Phone with the "New" screen was booted for the first time, the "developer options" & "adb debugging" were left enabled by me ( to backup my contacts , messages,etc) Could this have any detrimental effect on the capactive button light settings? I have thereafter disabled/enabled those options & rebooted the phone many times but nothing simply changes !
Btw, if all other functions of the phone is Ok ( i checked the phone's sensors with CPU-Z & everything was running fine) & the Screen touch response seems perfectly ok ,then also can this capactive button quirk be the result of Hardware manfunctioning /defect arising from the very New replaced Samsung Octa LCD itself? // I did not install any new apps, nor me,nor "Samsung Service Center" did anything on the Software part of my SGS2 recently //
Currently, only two options for those Capacitive button key lights work :1) always on & 2) always off & i have opted for choice 2 to save the distraction from the glaring/disturbing light of the capactive buttons & mainly to save some battery power !
So,if any body else have a great idea to fix the light quick , i would be immensely thankful to all !
i think u should reflash stock firmware and see if that fixes it.
yeah, Zyfloss, as you said it & i also similarly thought...i reckon the problem has been solved as of now with thë flashing of the SGS2 official Stock JB 4.1.2 Rom,the capacitive lights now seems to be working normal,timing out automatically after 1.5 sec or 6 sec as i want it ! Anyway, Thanks to Everyone who saw my post, tried to help & replied ! :good:

Samsung S4 (GT-I9505) 'back' key not working.

I've rooted my phone and flashed it back to stock 4.4.2 (TWRP recovery) because I wanted more freedom than 5.01 gave me. Everything workeds fine until it did an OTA upgrade back to 5.01.
At this point the back button stopped responding (menu button was fine). When I pressed the menu button both of them lit up, but the back button still did not respond.
I put it back to 4.4.2 again and the buttons worked just as they should, but again after an OTA upgrade the back button stopped responding. Getting tired of this, I flashed various other ROMs from Stock 5.1 to CM12.1 and whichever one I choose the same problem occurs. Only when I put it back to 4.4.2 does everything work normally.
I know I'm not the only one who has experienced this and I'm told that Samsung is aware of it happening in a very few cases, but no cure has appeared and it is getting really frustrating. Today I flashed a really great-looking ROM, which is a port from the S6 for the S4. There are one or two little issues with it, but guess what? Yes, the back button is disabled again. I have switched on the accessibility menu option, which puts a floating icon on the screen which when pressed has a few options, one of which is to go back, but this is only a workaround kludge not a solution to the problem.
Is there an expert out there that can tell me what all the later ROMs have in common which disables the back key? There is nothing intrinsically wrong with the key mechanism, such as it is, because it works perfectly under 4.4.2. I have the feeling that since this only affects a relatively few S4's the problem will not be progressed.
Does anyone out there know what is going on and can anyone help me, please?
