Chosen Solution
I just finished repairing one problem I had, where the screen gets all discolored. Once I closed it up and started it, it would not respond to my touch, nothing. I tried the S-Pen and it worked fine. Does anyone know what could have caused this? I reopened it and check the ribbon connections, the only one that looks questionable was the central ribbon cable. Now, I don’t know much about electronics, but I noticed that on all the other connectors for the ribbon cables, there was a locking switch. I don’t think the connection this ribbon cable has one, and I fear that out of ignorance I may have damaged the connector attempting to flip the non-existent locking mechanism. I believe this to be the cable that connects to the front screen (Not the LCD), and is what is used to communicate the touch input. So I think this is where my problem lies. Can someone enlighten me with their perspective on this issue? I think it must be a damaged connector (requiring me to get a replacement motherboard), the ribbon cable isn’t fully connected (tried my best), or something else I am not seeing. Hopefully it is fixable, I would hate to have to scrap a tablet just after 5 months of use. Could it possibly be a broken or damaged digitizer? I have dropped it a few times.
Brett Daniels, both situation are a possibility. The connector could fail to properly seat the cable, or it could simply be a digitizer failure. Post an image off your connector on here so we might be able to see any damage. If nothing else, you might be thinking about getting the digitizer replaced. Check on here to see if that is something that you would want to tackle. Hope this helps, good luck.
Just a thought. This seems rather simple, but there is a function of the tablet that can ignore the fingers while the s pen is nearby. If you tried to touch it with your finger while holding the s pen in the same hand, it would not work with this setting in place. -David
Dear All The problem is too easy…… just disassemble the back cover of the galaxy note then check all connection “specially the one near to the power plug” it must be fitted to the connection line ten assemble it again it will work “in shaa alla”. thanks
What I discovered after encountering this issue is that if my folio cover is folded such that the magnetic edge is in contact with the RHS of the tablet I get issues with touch, but not pen input. If I fold it such that the magnetic edge is on the LHS (or not near the RHS) there is no problem. It’s obviously got something to do with the sleep wake function with the folio cover.
My wife’s galaxy note had the same problem, nothing else seemed to work until we removed the cover! apparently the same problem that Grobolo was experiencing . Who would’ve thought. and this after she had been using the same cover, put on the same way, for a long time without problems until she updated it. grrrrrr.
I just want to thank all the contributors on this thread. This morning, I, too, dropped my tablet (onto a carpeted floor) and ended up with a black screen although I could tell it was still working otherwise. I was upset since I’ve only had it a few weeks and since I bought it used, well… There went my major investment of Christmas money. But, with a couple of YouTube videos, and all the suggestions I saw here and other forums where people really do try to help each other, I managed to fix it. Getting the back off was a trial, though and nerve-wracking for an only modestly technical person. The first time round, I got the screen working but couldn’t do any finger swipes, and the S-Pen was intermittent. So off came the back again. This time I made SURE the two cables at the very top (including what I presume is the digitizer) were really and truly aligned with the white guidelines next to the sockets. The tolerances are amazingly tight (every millimeter counts).
If you are having the same problem as the OP (ie the touchscreen works with the S-Pen but not your fingers), don’t take your phone apart. Just go to application manager (in your settings) - find Google Play Store and uninstall all the updates. Then restart your phone and the touchscreen will work again. If it doesn’t (but it will in 99% of cases), uninstall updates for other Google / Samsung apps. Then restart the phone.
Hi, I replaced my screen too and had the same issue. Touch is controlled by the top layer of the screen. http://www.ebay.de/itm/like/161955166515… It´s very likely that it´s connecting ribbon isn´t connected properly. I have taken off the cover, unpluged the battery, unfastened and pulled out the ribbon, put it in again properly and tight, fastened it by the clip, rehooked the battery back in, tested it and as it worked, put the cover back on. Hope your problem can be resolved. :)
Just dial *#2663# and that will recalibrate your touch screen. ….i can believe no one posted the real answer to this . Don’t take your screens apart guys…..just dial the number string
I just changed my screen and digitizer together because of the same issue (water damage). I recommend changing both the screen and digitizer assembly together because just replacing the digitizer can be very tricky. Watch this video for reference http://youtu.be/A1ntOfJS_1c?list=UUdCZPl… I bought the screen and digitizer for $185 and it took me a total of 45 mins to 1 hr to replace. Bought the assembly off of ebay http://www.ebay.com/sch/i.html?_from=R40… NOTE: I had to re- bend the home button spring clips (on back of main board) on mine and make sure that all the flex cables snapped into the main board because this results in the phone malfunctioning (aka the finger swiping not working on the new screen but S-Pen worked). I had to unclip and reclip the screen cable 3 times before I got it in correct. TRUST ME IT WASN’T HARD JUST TAKES PATIENCE

You have only one solution, 1- close your mobile. 2 remove the battery. 3- open the cover by remove all scraws and clean from inside then after that fix the cover and keep your battery then check it. This is issue happens with me yesterday and I solved it. thanks eng. Issa
