Hi,
when i connect the phone through MHL connector i cant use the phone, its like the phone loss al touch capabilities and doesnt respond at all...
is there a way of fix this?
the phone is with stock KI3 and CF Root.
thanks!
Im giving this thread a slight bump.
I just bought a MHL adapter for my S2 and I have the exact same problem, there is some response from the screen but it is very choppy and slow.
Playing videos/games works great and the back/menu/home buttons are as responsive as they have always been.
Anyone know how to solve this?
the touch screen problem accurs dues to electrical interference from wires/chargers in near proximity to the phone screen. The problem is only when the wires/chargers are faulty. (not is usage per se but causing the interference)..
the phone screen being capacitive - is prone to anything electrically conductive (including electrically charged air near it).
when you use the MHL adapter... try dragging the phone away from other clutter as far as you can ( keeping it still connected obviuosly)..and see if the problem still persists...
Suddenly my tablet has stopped detecting mini HDMI cable. I dont know what to do?
It was working fine 2 days ago. I even performed full factory reset on the tablet but still it doesnt detect. The cable is good, i checked it by connecting my phone to it. Please Help
Thanks,
You could have possibly busted the jack in the tab, its pretty fragile if bent around, also try very carefully flexing the connector around when plugged into the tablet. Sometimes connectors don't fit in as snugly as they should, therefore not making a good connection. Just make sure not to break the jack if you haven't already.
Well not sure if i broke it or not. But i tried many things like resetting the tablet, restarting etc. but still it wont detect the HDMI cable.
Hey there. I really need someone's help here. See, my Samsung Galaxy S3 has survived a lot of throws, drops, scuffs and scratches and it works great. However I hit the final blow last night when my phone broke into a few pieces. Now it's all back together the only damage done is ;
The Case is deformed
The Front Glass is cracked
And the touch screen no longer lights up nor does it respond to any touch input.
I'm trying to find a way to project my phone's screen onto my laptop without the use of apps or extra cables. Only cable I have is the standard USB Charging Cable. Is there any way I can use this alone and a WIFI Connection to display my phones screen onto my laptop?
I would like to ask if someone else experience crazy touchscreen behavior while your m4 aqua usb is in use, be it charging or data transfer. Its impossible to type, as it type at random or close/open almost every app or menu. But once I remove the usb cable it works proporly. I have a glass screen protector, but I really don't see how it would be connected with this misbehavior.
OS: 26.1.B.3.109, locked bootloader , unrooted.
touchscreens work by closing a circuit between screen and your finger..when electricity passes through cables it creates a magnetic field..what type of glass screen protector are you using..link to it?i have one too but i haven't got any problems like these

Sorry, I had to put a generic one [cheap chinese], as I couldn't found any branded in my local market. Though I just tried and it was working just fine with 100% battery, maybe its related to the a low battery state. Will try later.
Thanks for the repy.
Hello there. I am an early adopter of this device.
After all the disappointment with the wifi and gps capabilities and failing to utilize the tf201 as a light netbook replacement, I stowed it away somewhere and lost interest, as I didn't buy the thing to play angry birds. Now about two weeks ago I remembered the tablet and wanted to try amusing our cat with it (which amazingly works great, he is all about those cat video games now ) and got out the dock as well, since someone had apparently ported a few linux images to the tf201 more successfully then last time I read up on it.
The keyboard dock was pretty much an external battery it seemed. None of the keys would work whatsoever but the touchpad did. The battery was recognized and charged fine. I tried the sd-card slot and usb connector, both also working.
I have been searching the net for similar issues and found a lot of people whose docks were dead, with various symptoms. I tried a lot of things unsuccessfully and continued to use the dock as an external battery and for quick charging with the wall plug.
Well then yesterday I connected the dock again to charge the tablet a bit, and what do you know? the keyboard is working again. WTF? I have reconnected the tablet multiple times now, folded and unfolded the whole combo and it is still working today? Could it be a software problem? Is it multiple things causing this?
I decided to open a thread and gather information in one place, so that others might find it easier to troubleshoot this.
Following is a list of things that other's who have similar problems might try to fix/investigate. After that I will post some things that I have tried in order to troubleshoot my problems and please share what ideas you might have, as I am sure the problems with my keyboard dock will return eventually.
Here is what I was able to gather as potential root causes and possible fixes for dead keyboard docks:
1) The ingenious product design of the dock hinge makes it a premium dirt trap. Lots of bits and dust can get inside and will all the time, as the gap is wide open and there is convenient rubber on the sides with glue that dissolves and attracts crap that is basically uncleanable. But the connector is! So try cleaning the first. Sadly it is not easy to access but cotton swabs and a tooth brush with some cleaning alcohol will do it. The tablet side can be cleaned more easily but also isn't so problematic as a dust trap.
2) The flex cable inside the dock can become loose due to vibrations. This was a problem with the transformer generation before and they seem to have improved the design but I still read reports from people who had this happen. This is the easiest to fix out of all of these problems and if you have connection problems with your dock, make sure to check this. The dock is very easily opened with a phillips screw driver, a plastic prod (guitar pick, old credit card, cheap phone repair tools etc) and some patience. Be sure to not lift the two halves away from each other, as the cable connecting the top to bottom is very short and if you are not careful, you'll rip off the connector on the pcb. Check the flex cables and reseat them.
3) The connector between the tf201 and the dock is built very flimsily, but better then the first transformer series. The connector on the tablet side can lift off the pads it's soldered to due to flex and stress because it carries the tablets weight partially without a lot of support. The good news about this is, that if you have a decent rework station, this is potentially fixable. Opening the tablet is a hassle, you need a heatgun to soften the adhesive around the case (noone mentions this it seems) and slide the locking tabs in the recesses (where the tablet usually locks to the dock, left and right from the connector) to the open position. Then carefully pry the whole assembly open and get access to where the flex cable is connected to the dock/charge port. with a proper hot air rework station, that port can be reflown if the pins have indeed lifted from the pads on the little pcb. But this is also very finicky, as you will melt stuff in the process without shielding it from the heat (captone tape or maybe aluminum foil can do the trick).
4) Software? I only have theories on this but I think a lot of cases have some sort of software problem. What is known about how the dock functions?
- it contains a battery, which can be charged independently of the tablet. Charging this battery requires 15V and cannot be done with a common usb connection.
- there is a usb host connector, so there must be a controller for that inside the dock. it's not just wired through to the tablet, there is stuff happening here.
- there is an sdcard slot, so there must be some hardware responsible for powering and reading/writen to that as well.
- there has to be some sort of firmware, responsible for the low level things going on in the dock I am thinking, it has to do powermanagement for several internal devices.
so my conclusion from this information is, that maybe some of the problems could be caused there. how could this be debugged?
or:
- the custom rom could have a problem with the dock. The software side might be wonky for whatever reason. I am running a KatKiss 7.1.2 rom and AOSP is the only choice I can set as the hardware keyboard. Some people had success with hard reseting their tf201 or even a factory reset or reflash. A lot of people reported this did nothing for them.
TL;DR if your keyboard isn't working, your dock isn't charging, or some other feature on your dock seems dead suddenly, try the above things and please report. I am trying to collect all info on this to help people troubleshoot and investigate these issues.
- I have tried to hard reset the tf201 with dock attached and without. didn't help.
- I opened the dock and reseated the flex cables, but they looked fine in the first place. Also didn't help.
- I tried fiddling with the keyboard and language settings, also did nothing. Don't want to reflash/change roms just yet, I couldn't gather any cohesive info on wether people -had these sorts of issues due to a custom rom.
- I cleaned the connector on the dock and the tablet with isopropyl and got out lots of gunk but this also did not help.
now I was about to reopen the tablet (I was in there before to fix something on the case), but then it suddenly started working again. So I am pretty reluctant to just open the tablet to check at the connector pcb, since it is quite risky and I am glad I was able to get the thing back together so neatly, after I opened it the first time. I have a hot air rework station and a microscope to check and repair this, but now that I am thinking it might be a software issue after all, I really don't want to risk ruining the tablet. It's obviously not made for being repaired/maintained (thanks ASUS, it's not like it was extraordinarily expensive...).
Here's the issue I had..

Having missed the window to have this repaired by Asus I just leave my keyboard in a drawer to keep papers from curling.

thanks for that link. So that apparently just concerns people who have a dock that has it's battery draining, which I am luckily not one of. I also did the test described in the link, so I guess powermanagement is not affected by the firmware incompability in this regard.
