Multitouch issue - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hello everybody!
There's something strange happening on my P5110. Here's the thing... when I use the tablet with one finger, everything moves as smooth as I expect... but when I try to use the pinch to zoom or just the multitouch (2 or more fingers) it may become less responsive and less smooth at the scrolling. The way to fix that is by shutting down the screen and turning it on again (I presume that it's a software issue). I use the stock 4.1.2 rom and I tried with factory reset and by searching the web, with no success. Any ideas?
I hope that someone could help me out with this issue.
Thanks in advance.

Hi Barktooth ,
I had the same problem with my P5110. I was on stock 4.03 DBT and after the update to 4.1.1 Btu I had the same issue with pinch zoom like you.
I tried everything .. flashing other stock versions, resetting and so on. But the problem stayed. Then i sent it to samsung. They reinstalled the stock 4.03 DBT version. But the Problem wasn't solved. I sent it again to samsung with a video to show them the issue. Now they solved the problem by changing the motherboard. I'm now on stock 4.03 with a new motherboard and without any issue. I think you have to send it to a samsung service center. Did the problem appear after flashing a stock rom?

Hi fredy66!
Thanks a lot for the answer. It was exactly the same for me. The issue appeared after flashing the 4.1.2 stock firmware... and is staying even if I flash another firmware or by hard resetting my device. I have far mor problems though... I don't know if there's any Samsung service center around my city and my warranty is gone. I'll try to find one.
Thanks again for the answer!... I thought it was a software issue... but now it is a hardware issue =(.

Hi Barktooth,
This is really strange. Maybe it's a software problem and the service center only couldn't solve it by flashing the normal stock firmware. It's possible that some p5110 needs a special driver because of a problem with the touch controller on some motherboards. Did you update the tablet with kies or by ota? I flashed my p5110 with odin. Have you tried cm? I'm now afraid of flashing again.

Hello fredy66!
I flashed the 4.1.2 stock firmware via odin too. I tried reflashing another version without luck. I'm gonna try with the 4.2.2 stock firmware and see if that solves the problem. It's really strange... I had a Galaxy S for a long time and flashed it like there was no tomorrow... nothing happened to that device... it works flawlessly even now. That's why I thought it was a software issue... but it seems that just a few of us had the bad luck =(.
I'll try the 4.2.2 and if it solves the problem, then I'll tell you through this topic
Thanks again for your time!

I have this problem also, im on CM7 nightly. cant unlock the screen. Phones barely 3 days old
Had that same problem, and it's gone now. Don't know what did fix it, but I flashed new radio and Trinity kernel, and the problem is gone now...
I thought with the 2.3.5 the problem was solved, but its back now... dunno what it is, my phone is 2 weeks old.
I'm experiencing the same issue on a stock, not rooted or in any way modified Nexus S I9023 (SCLCD version) with Android 2.3.6
Also the settings button is right under the line (so the location is different from the video) and it is unresponsive as well.
Does anybody have any idea what to do about this???

[Q] Wifi Issue!

Guys see when i use wifi it first does not connect to the network and it only works after i reboot my device. Can somebody please help me?
fw version? custom rom? custom kernel? settings?
Are u using any UC KERNELS? The older versions have this glitch, try using the new one, it works gr8!!
☞★sent from drajax's Galaxy SL!!! *♂ツ
I am on stock kernel.
also stock fw, etc? it just broke with nothing done to the phone? more details are still needed
I am on a custom rom Concept Agarwalca V2. XXKPQ as firmware and stock kernel.
Fixed
I fixed my problem via an app! Thank you for helping!
try MIUI or cm!
Guys my problem has become even more aggravated! 1st it was connecting after a reboot now it doesn't connect even if I reboot. When i dial *#*#525#*#* It tells me driver loading failed! Somebody help me please!!!!!!!!!!!! PS: I even factory reset it installed the rom again still the same issue!!!
do everything over. flash pit, kpe, kpq and do not install anything. just start the phone and test wireless to narrow down the source of the issue.
I tried that! Maybe somethings wrong with the motherboard!!!!!!!!! I hate this guys! Can somebody help me!!!! My driver loading is failing everytime!!!
well, sorry to say it but you got your answer. if modified stuff isn't causing the issue, it's the phone itself. gonna have to get it serviced...
Supergaijin thanks for helping i solved my issue! The wifi was just taking a bit of time to load! If That doesn't work everytime! Maybe service center is my only option!

[Q] S8500 "Call not Allowed"

Hey guys i recently flashed my phone with TurkoCFW V6 and now am having a problem calling. Every time I try to call it says "Call not allowed". I saw other people posted the same issue but no one replied with a fix. I even flashed my phone with a different firmware after the problem happened and it hasn't helped. I have previously flashed my phone over 25 times with no problems so I have no idea what to do. Has anybody found a fix for this? Cause I mean a cellphone is pretty useless without calls...
I spoke to Hero355 and he gave a file to fix it with which worked but somehow only works with his firmware. I tried flashing with an official firmware and the problem persisted after which I tried flashing the firmware with his fix which just messed up the phone even more. I mean it works with his firmware but his firmware only.
I do not understand how this problem persists after reflashing if its wiping everything and reinstalling everything...
So I want to switch firmwares but cant because of this problem.
Would appreciate any help, Thanks!
please someone help...

Galaxy S6 Speakers' Issue

Hi buddies,
I know maybe It is a wrong place to ask this, but I've got a strange problem regarding to speaker.
My speaker in my S6 gets some ticks and lags during the play. I mean constantly the music stops and plays over and over.
I have the issue frequently and at the moment when I check the hardware with *#0*# there is no problem with the speaker.
I have the problem in games softwares and music players, and just recently got it.
I've tested different ROMs and kernels, both stock and unofficial, in both Lollipop and marshmallow, but the problem is still keeping up.
Attachment I've uploaded you an instance to better understand the problem.
I really appreciate if you just give me a hand with this.
Thanks.

What model S6 do you have?
Might have installed the wrong model, can you please try to flash an original stock rom and see if that works then go from there to see where you went wrong

I've got the international version (G920f).
I've flashed stock ROM bunch of times from different bases, and now I am on stock marshmallow ROM with stock kernel. Still have the issue.
If you've tried different stock roms I'd say your speaker is faulty? If you haven't triped Knox send it back?

But I test during the issue, the speaker is allright, (using *#0*#)
And also I don't enable the Knox at all.
When I use that code I goto imie viewer. Knox is always active on stock rom regardless, it sounds hardware related not software, since you've tried other roms and it's still the same issue it doesn't make sense that you broke your device speaker.

Oh, I really sorry that was a blunder
I meant *#0*# ...
So How can I really make sure that It's a hardware issue?
Does flashing ROM with box helps?
Well if you keep flashing different roms and nothing is working to fix the problem, which is including kernel issues on stock and custom I'd say it's hardware related.

I tried a Miflash but it still doesn't work, firmware v. 9.5.2.0
with firmware v. 6.1.7 the situation is even worse, after taking some pictures the phone restart itself
I think it's a hardware problem at this point
