Weird fault with Note 10.1. Help!

Hi guys, newbie here, and im in desperate need of your help!
So I decided to buy an Note 10.1 and yesterday I received it. Straight away (after turning on) I noticed this rather irritating noise (like a notification sound but not one that is the ringtones options on the tablet) that the tablet made when I held it with one hand well, at first I thought it was a motion gesture since whenever I hold it with one hand (the right hand) it switches to the previous app if your in an app, or previous Web page when surfing the net. So I searched the options 100 times, and nothing to toggle off.
Anyway it bugged me more and more and I couldn't figure it out, then by chance i just pushed slightly on the back of the tablet and the notification noise goes off. Push again, it happens again. I decided that it could be a loose connection being made and remade every time I decompress the right side back panel (I can play it like a piano). So I took the back panel off (a pain in the ****) and noticed a ribbon cable that runs directly where I push the back panel (the S pen sensor cable). It was plugged in correctly, but wasn't taped to the battery like the 2 fatter ribbon cables.
So, I taped it down thinking that me pushing the back panel was moving it and creating a loose connection. I thought I had solved it. Booted it back up, no sound!!!!! Reinstalled the back panel, booted again and BOOM, the sound returns.......
Gutted.
Not sure what to do next, it definitely sounds as if something is disconnecting and reconnecting like a USB on a PC, im getting the sound but no notification or error. I have no idea why this would make an app switch to the previous app or webpage when on net.
Any help would be much appreciated.

Well, it seems I have solved the issue. Since this is a new account, I can't post youtube videos. So I'll leave those out for the time being.
Firstly, heres a video showing the fault. As you can see, I've narrowed it down to the docking station/charger connector.
The ribbon cable was seemingly depressed causing it to disconnect briefly before reconnecting when released. Probably the down side of having a flimsy plastic case.
Solve the issue I removed the ribbon cable and taped a small amount of foam right at the mouth of the connector, making the whole connection sturdier and harder to depress with the cover on, which can be seen here.
Hopefully this helps anyone who finds themselves with a similar issue.

that woulda went straight back to the store

Yep, if the problem isn't fixed there's no way it'll get fixed under warranty now...
If the device is less than a week old, in Oz, the shop is supposed to replace the device immediately. This doesn't mean they won't try the old "It'll take 2 weeks to fix" and "It has to be sent back for repairs" schtick....

Cracks are not always visible. But if they're not there, I'd suggest you open the back case and try to reseat the ribbon cables at the touchscreen PCB. While at it, check the flat silver cable connecting that board to the mainboard also. Make sure nothing is jarred loose by the drop.

thanx for responding...i did exactly what you said ..i disconnected both cables (silver and brown) and put them back..more than half of the screen started working, the other part was just dead and those parts didnt work even when i tilted the screen.. like 5 minutes later the entire screen is dead again......do you think its the digitizer?

Sorry for the late reply. I've run into this problem before. When you have a digitizer that works for a few minutes then stops as the tab warms up, (1) more likely than not, there's a crack somewhere or a tear on the ribbons, visible or not, or (2) the new screen boycotting the old firmware. No new screen points to faulty hardware. However, it doesn't hurt to eliminate possible software causes.
The best test I can think of at this point would be to first check the physical connections again (check the connectors and ribbon ends under a magnifying glass, make sure they aren't damaged, bent or stripped), then re-flash the firmware following instructions in another thread, then turn on "show touches" in settings. If you still see "ghost touches" after a few minutes, the digitizer is likely ass-kicked by the drop.
I've had a digitizer on a TF act "leisurely" because of a crack across the width of the bordering black strip that couldn't be detected with the naked eye because it severed the circuit on just the underside. The surface was totally smooth. As the crack spread, it became obvious.
If I had access to your glass, I could've tested for you. Too bad.

[Q] Screen stops working intermittently, seems to be hardware related, help?

So I've been having a ton of issues with my phone lately, to the point I can't use it anymore. I'll list them in case they may show what the problem is. First, the charging port went out. I swapped out for a new flex cable on ebay and all was well again. Next the speaker stopped working unless I would squeeze the bottom of the phone, and then stopped working completely (Not sure if this was the speaker itself or if it was making poor contact with the new flex cable.).
Up next, and the worst problem of all, is the screen stopped working intermittently. I seemed to be able to get it working better when I would squeeze the phone, which seemed strange to me. This kept happening until it stopped working altogether!
So, thinking it was the flex cable, I just swapped it for another new one from a different seller, and it still isn't working. If I reboot the phone the screen works perfectly fine unless I put light pressure on the back of the above the "s" in nexus, then the screen shuts off and won't come back on again until I restart the phone again. As soon as I reboot the phone the screen works great again until I tap that spot.
I'm a bit at a loss to what I should be looking for, or what I need to replace? Is there some sort of short? Is a connection poorly made? It's a brand new flex cable and the old one seemed to be doing the same, and I've double checked the connections and they seem to be fine.
If you have any ideas, I'm all ears, just about to tear apart the phone to check where it might be making shorts around that area! Thanks everyone!

Seemed to be an issue with the flex cable connecter to the motherboard. When I added pressure to the connector the screen would work, as I let off pressure the screen quit. I ended up adding a few layers of electrical tape to the back of the connector so when I put the backplate housing and cover back on it would add some pressure. Seems to be working great now (knock on wood).

Thats a common experience you had. The connection between the USB cable and the motherboard for some reason can go bad. I suspect overheating may be the primary cause. The careful placement of double stick electrica tape appears to help fix this problem. I had to do it myself. The speaker not working can be caused by poor connection to the USB flex cable. There is an excellent youtube by "LE55ONS" on the disassembly/assembley which shows everything in great detail. It's worth a look.
Glad you got everything working

[Q] Stuck on booting up Samsung screen

Hi,
My Note Pro 12.2 P900 64gb is now stuck on the samsung screen of booting up and I am wondering if anyone can help me figure out what to do next.
I was experiencing the flickering issue for the last two weeks which got progressively worse and eventually caused random rebooting. One time last week it started booting slower and then it wiped out some widgets on my start screen and the apps in touchwiz but most everything else was OK. Then yesterday it would not boot up past the samsung screen. It charges up OK, and I can get to Odin where it asks if I want to load another operating system by holding power and vol up. But unless it is plugged in, just holding power off puts it in a boot loop.
The other part is if it is stuck and I hold power off it usually vibrates twice before boot looping.
I rooted the tablet when I got it, but still run stock touchwiz, I just needed some rooted apps namely LMT pie controls.
Can anyone please point me towards what to do next. Thank you very much for your help.

I guess wiping data and factory reset is your only solution right now
I shall warn you you could lose your data so I hope you already have a backup!
And also I've read that lollipop fixed flickering issue in p900 devices
I hope everything goes well for you
Good luck

hey there, you are not the only one, check this post. it seems is somethig related to battery issues

When power on, try pressing on the back, near the center with your hand. to see if it can boot normally,
Keep pressing while power on. if it works I will tell you what causing this problem.

here you can look by the minute 2:30 where the connector is located, basically under the samsung logo. I'm not doing tests yet because i have a busy day ahead

Thank you all for the responses. Holding down the back while powering on does not help. I do have the flickering thing and that started leading up to this. Lay night I took it the battery and disconnected it for a half hour and that did not help. Looking at the connections with a 20x hand lens did not reveal any cracks.
I don't remember how to wipe the data off the device, I got it right when it came out rooted it with cf root and never got around to twrp. All I wanted was LMT and Xposed. I never even updated the OS.
If anyone can help walk me through this to get it running again I'll send you a green poetic skin used once or a white well used GumDrop hideaway case I tested for work. I just would like to get this running instead of needing to purchase a new one.
Thank you again. Sincerely.

Flickering screen is caused by cracked battery connector which cannot be seen under magnified glass. Re solder will fix it, trust me I did fix some of them

So resolder the 6 posts connecting the battery connector to the motherboard? Is there anything special I need to do that, just my soldering iron with a fine tip and solder? Anything special I need about the solder or do I need a wik or anything? The last time I did any soldering work was about 25 years ago.
Also will this fix the bootlooping and hanging on booting up at the Samsung word on the screen? If it is not going to fix that problem, maybe I should look at something else first.
Thank you very much again for your help.

First, pressing the battery connector help your tablet to boot is a confirmation of cracked battery connector solders. 90% flickering problem is from cracked battery connector. 10% is bad battery. You should fix the battery connector first as it's major defect seen in many Samsung tablets. Re solder is simple, apply flux, then heat these pins and add more solders as possible to secure these pins. Even new main board, this connector will crack just after 3 or 4 months depending how you use your tablet, especially with who using it on their laps. The main board sits on a flexible LCD and only 3 screws to hold it to the frame at 2 speakers. You don't need to remove the main board, just disconnect your battery and re solder the connector from the top.
Be careful as this connector is very close to other components. Trust me, this re work will fix this problem as I have seen in some cases, battery jumps up from 8% to 45% after the re work, other cases pressing the battery connector help the tablet to boot or stop flickering.
This person applied the fix and succeed.

I have the Note Pro 12.2 and I had this same screen flickering issue. It would start to flicker at first around the 38% mark. I did research online and found this thread and many others. I tried the software fixes like the enabling of Developer Mode and screen brightness and other tries, but to no avail. When I pressed on the back of the tablet, the screen flickering would stop but then shortly return. So I saw the fix of trying to raise the motherboard which worked for about 2 weeks, then the screen flickering did return. It would then start to flicker around the 58% battery level mark and when it got down to around 26%, the tablet would shut down. When I plugged it in, it would show battery level of 0%, then quickly jump back up to the 26% mark when it shut itself down. So then by this time, I saw more of this thread and now was shown the soldering of the battery connectors. I had soldering equipment, but it was too large for this repair as these 6 pins are very close together. So I went to the hobby shop and purchased new equipment for about $30 with a smaller pin to be able to do this. Now, I am not an electronics guy and my past experience was replacing two bad capacitors on my Plasma TV when it went bad. That was the extent of my experience to date. So I opened up the back of my tablet and soldered the 6 pins again and the screen flickering has not returned. I am on my 5th battery cycle from 100% all the way down to 2% and the screen flickering and shutting itself down has not returned. Some people have said an electronics guy will do this for you for around $30. Well, I spent the $30 and did it myself. I want to thank the people for posting the solutions here as the soldering worked for me.
And from this post, a confirmation that repair center will do the same thing to fix flickering , auto reboot, auto shut down.....etc...all problems caused by cracked battery connector ( Connector Header ):

Ok I'll try to resolder it this weekend and report back. I think that my pertinent problem is that I have both the battery issue AND another problem that the tablet won't boot up at all but I will try the battery fix first and see what happens. Then I will report back.
Thank you very much for your suggestions.

Your feedback is very important as I see many " Hit and Run " users, they get the solution they need but never post back. Your first priority is fixing the battery connector, then next is the battery if problem persists.
This is a hardware defect I have seen in many Samsung tablets: battery capacity fluctuation, quick discharge, auto reboot, auto shutdown.......all come from battery connector . Read the threat Flickering Screen you'll see others try all solutions but never work because they don't know this is a hardware problem coming from this tiny connector.

Dropped my P900! Blackout!

I just dropped my P900 and it went completely dark. :crying: There's no mark, not a crack, nothing, but the display is completely dark. The touch buttons on each side of the home button lights up, but the display does not.
Any advice? Or it is Samsung support next?

May the ribbon for the display is disconnected from the circuit board.

Yeah, maybe I should open it myself and have a look. Are there any warranty seals that I will break if I pry it open? I have all the tools necessary, but are there any guides for opening the P900? I wouldn't want to break anything...

This is a video on replacing the battery but it helped me when I re-soldered the battery connection on mine.
https://www.youtube.com/watch?v=VeSG0hHpAG8
I've opened mine a few times and haven't noticed any specific seals but mine was refurbished to start with.
Also I have the proper tools but found a guitar pick was easier to use personally on this tablet.
Starting at the power port to remove the back made it a lot easier for me, its pretty hard to get anything between the back cover and the tablet in other areas.

This was indeed the problem! The connector has some kind of snap lock that had come loose. So easily fixed. Thanks for encouraging me to try to fix it myself. :good:

Glad I helped!

Sorry to hijack your thread but figured my problem might be related.
About 2 weeks ago I charged my tablet and stored it away. The other day I tried to use it and it wouldn't turn on. I tried to charge it but that didn't work either as there isn't even charging activity on the screen. I ordered a replacement battery thinking it might be that, but I was wrong. I still can't make it turn on. Any ideas what it can be? Thanks

I had a similar experience. 3 weeks ago the 1x my SM P-900 is out of its protective case, it falls 2.5 ft off a table. Hits the floor. No visible cracks or breaks. I could hear hear it operating but the screen was black. Took 3 weeks to talk myself up to it but I pried off the back & used a magnifier glass to c.a.r.e.f.u.l.l.y check every ribbon connect. 1 connector's pins were very slightly off alignment. Couldnt find anything else. Put it back together...Yes! Screen works. All seems good. Took the back off again & securely taped over every ribbon connect I could find. Long time intermittent screen flicker issue (when battery was below 40%) also seems to be gone. That has been the best, eye squintin', back hunchin', shallow breathin', micro-screw wrangling, time investment my non-hardware tech self has ever spent. Wooo!
