[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Nikon5400:
Can you tell me how you re-create this issue? It was ALWAYS present on mine when battery was low and apps like youtube or speedtest were running. Now when the warranty is about to expire I can't re-create the issue. I'd rather have this issue fixed under warranty then have it come back a day after warranty expires.

If this is a cracked connector issue, wouldn't I still have this issue?

Do you know if the cracked connector issue contributed to the heat issue? My tablet was hot to touch near the camera and the battery temperature was over 105 (while other one was always under 100 when running the same tests) Now it gets barely warm. I'll install the battery temp app again and check the temperature.

One thing I didn't mention - the tablet after being used (and abused) by kids is making cracking sounds if you try to bend it a little (I have another one to compare). Could the side effect of the abuse be the reason I don't see this issue any longer?

I read somewhere removing the battery for a few seconds fixed the issue for some, but then the issue came back for others.

Someone else mentioned the issue had to do with the charger's usb3 cable connector and not the tablet itself and switching to miniusb fixed the issue.

I have 2 usb3 chargers, so I could have been using another one lately. I'll switch the chargers next time to see if the issue comes back.

Also, I figured if removing the battery has fixed the issue for some, maybe new OS fixes it for me.

I have not used this tablet for a few months, I can't be 100% certain the issue went away with 5.1.1, but I updated to 5.1.1 about a week or two ago and was trying hard to re-create but couldn't. My warranty is about to expire and I waited this long hopping samsung may just replace it (and hopefully with the newer model) instead of fixing it, but there's no newer model and if I can't re-create the issue samsung tech won't be able to either and even if they replace parts I won't be able to verify that they did.

Could you provide a link to pictures or video with cracked connector issue? If this is something easy to fix, maybe I'll forget about the warranty and just fix it if the issue shows up again.

Thanks

Cracked battery connector is widespread problem of this tablet and its similar tablet 12.2 Tab Pro.

Cracked battery connector cannot see with your eyes, these cracked hairlines can be seen easily under microscope. I can test it by pushing left or right or lift up, but doing this when it's ready to be re soldered. Common problems of loose or cracked battery connector: flickering, overheating, burning smell, quick discharge, auto reboot, auto shutdown, hang at boot, battery's capacity fluctuation, not turning on...etc..

This problem can be seen easily when battery is low, depending how bad of the crack, one can be seen at 30% but other flickers regardless battery level, even at full charge.

I actually bought 3 of Galaxy Note Pro on Ebay with the same problem of flickering and the fix is simple: re solder battery connector. The three Tab Pros I bought, all look like new but they have the same problem.

If you don't want to mess up with your tablet, send it to repair under Warranty, and you should emphasize on the battery connector issue and address in your complaint: overheating, quick discharge, flickering.

I believe Samsung aware of this issue and what they will do to fix this problem:

1- Re solder the battery connector.

2- Solder the white battery connector directly to the black battery connector. I think this one is not necessary as they can do this way:

[IMG="Adjustment of Battery Connector"]http://www.mediafire.com/convkey/ccd3/z8t3ysov3vr364q6g.jpg[/IMG]

This connector has obvious cracks at two center pins, others pins the crack may be under. The crack is not severe so this tablet only flickers at around 30% battery or lower.

[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Nikon5400:
yes but mine stopped flickering completely.

I wonder if kids tried to bend it too much and that somehow made the connector issue disappear
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
You can test it by running at low battery around 20% to 30%. I have one that I run fine from 100% until 29%, then it begins to flicker.

Believe me or not, Lollipop cannot do the magic of fixing hardware problem and the thread of flickering is the most read in here, over 30,000. In Android Central Forum, it has more than 100,000 views as of today. These numbers can tell you why this problem is so popular in this tablet.

Just received my notepro back from the repair center!They replaced the battery and the connector and the flickering is gone!!!I was afraid i would have to pay because the tablet was rooted, but nothing they repaired it anyway!
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Nikon5400:
I've known about this problem and reported it almost a year ago. The easiest way to recreate the problem was to run youtube or speed test when the battery level is under 20%. But I can no longer recreate this issue using these two apps.

The tablet used to get hot but now it stays cool.

What other application can I run to force this issue to show up?

I want to be able to recreate this issue so I can fix it under warranty and be able to verify the issue has been fixed.

I understand this is more of a hardware issue but I thought maybe Google fine-tuned some library or something and now applications consume less resources and not stressing the hardware as much.

please let me know which applications use more resources, make tablet run hotter, etc.

P.S. The tablets I have are Tab Pro12.2. I've had about five of them, one white the rest are black. Only the white one has (had) this issue.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
Just use normal application like youtube or playing a movie while bluetooth, wireless are on, brightness is at maximum. Flickering usually start at low battery level, depending on each tablet, one can start problem at 80, others may start at below 30% battery. The only way you can test is running until the battery runs out to know when flickering will start.

You are under warranty, just use it as it happened before. I don't think they have time to test until see the flickering. Like mine, the one I bought with flickering, I had to run it for 5 hours until seeing the flickering screen at 28% battery.

By the way, it's covered by warranty, just send it for repair as you have nothing to lose. When it's out of warranty, you have to pay for any repair.

You're lucky when your tablet was repaired by a lazy tech who did not check or didn't bother if your tablet is rooted.

If the tech reported it's rooted, your tablet will put on hold, warranty status will change to out of warranty, and Samsung CSR will contact you for out of warranty fees.

That's why lazy techs don't bother if your tablet is working fine, passed tests.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Nikon5400:
You guys were correct and I was wrong. The problem did NOT go away on its own (with 5.1.1). It got better but didn't go away completely.

I can re-create this issue with speedtest, battery < 20% AND BRIGHTNESS AT 100%. . I never touched brightness setting before, so I'm pretty sure 5.1.1 or something made it better, because the issue isn't there with normal brightness level and the tablet doesn't get as hot, but the issue did not go away.

Thanks for convincing me this is a hardware issue and it couldn't go away on its own :)

Three times at Samsung service. Third time they resoldered the battery connector. Or so they claim. Tablet still flickers, although not as much as before. *sigh*

The white battery connector also is the source of flickering, I had one that flickering at 70% battery. The fix is so simple but you might need magnified glass to see the connector end: pushing the opening closer, they will make good contact. They re solder the black connector without fixing white battery connector will not fix the flickering problem.

Samsung service centers in US solve this problem by soldering the white connector directly to the black battery connector, but you don't need to do this, they solve the problem but customers will face difficulties when changing battery.

I've had my N12 for three months and have only used it on Lollipop. The screen flickered under certain lighting conditions when auto-brightness would lower the brightness in response to changing lighting conditions. I don't know if that's the same issue everyone else is/was facing. Based on how it occurred I thought it was a graphics driver or sensor issue. It was. I upgraded yesterday to the latest European (OXX) ROM and the flickering went away. So you might want to Odin upgrade your N12 with the latest ROM before performing surgery on it and voiding your warranty.

Try pressing the back of the note pro over the Samsung logo I have found that it works(did for me) it's a loose battery connector issue samsung cheap build, I know anyway if you have tried that and are frustrated of touching the Samsung logo again and again as the issue reappears then I suggest pull the back cover (use youtube) and unplug battery connector and plug it back again if you are unsure then just push battery connector downwards a little. I have tried all and first my note pro used to flicker at 46% battery level now hasn't flickered once till even 6% battery level moreover I can also say that battery life and performance has dramatically in proved as well!!!( By the way used geek bench and an tutu to compare) Hope it helps!! 'cause it sure did for me!!

If you don't know how to solder, a silver conductive epoxy might work to fix this cracked battery connector. But re solder still is the best fix and it takes only under 5 to 10 minutes.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] luffy092:
Hi all,

After reading all posts found on the Web about this issue, I tried everything :

- upgrade to 5.1

- change settings as recommended

But after all, nothing worked.

I got a Note Pro 12.2 since 2 years now and just a few days after end of warranty, I started to get the flickering issue.

Like others, the tablet works perfectly until it reaches under 80% of battery.

If I use an application that do not require high CPU or GPU (like comics reader or watching a movie), the tablet can work correctly without flickering (and rebooting).

But if I'm under 20% of battery, I got full issues and reboots.

If I use a game (clash of clan or others), I got immediatly the flickering issue if I'm under 80% of battery.

And if I plug the battery to power, no problem at all, I can play of do anything without fickering.

I saw with these posts that it would be a hardware issue so I would take a chance and try by myself to correct it.

So I watched videos that explain how to open, then I would have a look about the recommandation to install piece of plastic to raise up motherboard.

But video is not available anymore and I don't understand where to install the piece of plastic.

I saw " install a thin plastic shim under the mother board to the right of the battery connector" but I don't really understand how and where ?

Since I opened my tablet, to disconnect and reconnect cables (battery, LCD and Wifi), my tablet works perfectly !

I could do a full charge, and use the tablet with games until the tablet had no power without any flickering or others issues.

But I would like to be sure by installing the piece of plastic.

Is there anyone that still have the video of peterjo78 ?

Of would it be possible to get a picture that shows where the piece of plastic should be installed ?

Thanks in advance.

Hello. After some reading and testing of one Samsung SM-T900 I found the same thing as Beut says - cracked soldering on the connector. I resoldered all the pins and now since last 10 hours of testing it it is OK. No restarts, no flickering on the screen.

Posting picture from my microscope of the problem before resoldering.

I know this is a very old POST, but I have a Note 12.2 and i love it...no problems I bought one for my wife on EBAY...the idiot sent a TAB 12.2 and wont refund without me paying a restocking fee of $100!!! So, we kept it...now 2 weeks later it strobes/flickers under 50% battery when unplugged...I found the main culprit for this issue on 99% of the tabs is the battery cables need soldering! Theres another $100!!! I wish Samsung would do a better job!!!! What was your fix if you dont mind me asking????
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
Don't send to Samsung as you will regret it. They solder battery cables directly to the battery connector, it will solve the problem of loose connection but create problem afterward to users as they have no way to replace the battery without removing the solders

[IMG="Cables soldered to battery connector"]http://www.mediafire.com/convkey/c4ce/z7127f22cvnazjf6g.jpg[/IMG]

You can bring to any repair shops where they can do the rework, they don't necessarily know how to repair a tablet.

The rework only takes 5 to 10 minutes, all you need is removing the back cover and disconnect the battery, they can do

the rework from the top without removing the mainboard. The battery connector has to be resoldered to fix hairline cracks from solder joints. The cables don't need to solder directly to the battery connector as the way Samsung do, you only need to adjust the tip of cables closer to make firmly contact to pins of battery connector. You need a magnified glass and a thin knife to make this fix. Many people fix the flickering screen by a new battery, but actually they don't know they throw away a working battery which only needs to adjust the tips of cable from the white battery connector.

Note pro screen flickering! Help! !!!

I have purchased 2 note pro tablets, about 5 months apart, and both of them have screen flickering issues. I have sent them both in to Samsung repair center 3 times, and all 3 times received the tablets back unfixed. Apparently they do not even turn on the tablet and look at the screen, I guess they hook it up to a diagnostic machine, and that is not acknowledging the problem. I love my note pro tablet, and use it for work, but I'm getting very frustated with Samsung. I have been reading up on this issue on here, and it is apparently caused by battery connectors being cracked. I would appreciate any info on what to tell samsung the problem is to ensure that they solder the battery connectors. :confused:
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
Samsung turns around time policy is 1 day and Samsung repair centers, who are contractors, only allow techs spending one hour for each tablet in order to make profit.

They don't hook up to a diagnostic machine but techs have only one hour to complete a repair, that's reason they cannot troubleshoot correctly to this particular problem which requires a tablet runs low on battery to see the flickering screen. Believe me or not, Samsung contractors are the lowest bid winners and they usually hire low skill techs to do the repair in order to make profit, so no wonder they make many second or third returns. However, you should contact Samsung and demand to speak with upper level personnel, a tablet repair more than 3 times, they should send your a new replacement, this policy applies to any company.

I don't know which center you sent to repair, they should know how to fix this issue which is very common in this tablet and Samsung is well aware where is the source of problem. You should have all RMA numbers in your record when speaking with upper management person, don't bother to speak with a low level CSRs. If you like , file a complaint with BBB. Trust me, when BBB is involved, Samsung will immediately send you a new tablet with no question ask if you're still under warranty.

Or this one

https://www.usa.gov/consumer-complaints#item-35997

I bought a tablet from EBay, FedEx tracking showed it delivered but I didn't get it, probably it's stolen, EBay support the seller for not refund. After filing a consumer complaint and sent the receipt to EBay, I immediately got the refund.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Kmhastings:
Thanks so much for comment. The only thing I'm worried about getting a new tablet, is that it will start doing the same thing. In your opinion should I try to send them in one more time to try to get battery soldered or get a replacement ? Thanks again .
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
This is a simple fix for who knows how to solder, however if you want to repair again, be specific in your instructions : fix battery connectors and tell them: " Do not solder two connectors together ".

See the picture in my previous post, a tablet previous repaired from a Repair center , they solder battery cables directly to the connector on main board.

A new tablet gradually will have the same problem, I wonder where did you send your tablet, Texas or California ? These incompetent techs should know how to fix these common problems, well known for this tablet
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] BIZBilel:
Dude what happens if you solder two connectors together ? cuz that what the guy who soldered mine did ...
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
They solder battery cables( 2 positive, 2 negative ) to battery connector on main board to avoid loose connection and to save the cost of new battery.

In case the battery is dead, you have no way to take out the battery without removing the solders. Someone had no idea two connectors are soldered together, damage the connector and main board while removing the battery cables

There are two sources causing flickering screen:

1- Cracked battery connector on main board.

2- Battery cables has loose connection to connector on main board.

Repair centers will fix both: re solder battery connector, solder battery cables directly to battery connector on main board.

However, there is no need to solder battery cables directly to battery connector, I fix the loose connection by adjusting the opening of cable closer

[IMG="Fix connector"]http://www.mediafire.com/convkey/2e3f/rbhz5n89vmd5ria6g.jpg[/IMG]

Or using Silver Conductive glue, this one is available on Ebay or Amazon, under $5 . However, you have clean up the glue between terminals, otherwise you will experience overheat or low temperature problem due to short circuit.

[IMG="Siver Condutive Glue"]https://www.mediafire.com/convkey/14d2/xatvmi23chjavm26g.jpg[/IMG]

In this white battery connector, unknown to many users the cables can slightly move right or left, this is when you have intermittent connection

[IMG="Battery Cables"]http://www.mediafire.com/convkey/f2c0/wtfdrpc0rers8jb6g.jpg[/IMG]

Repair Center fix this issue by soldering directly positive and negative cables to pins of battery connector on main board

[IMG="Cables Soldered"]http://www.mediafire.com/convkey/565f/po850ugpl7ty8c86g.jpg[/IMG]

They fix the issue of loose connection but average users will face problem of replacing battery as they need to de solder the battery cables.

Then they need to send back to Samsung for a simple repair: replace the battery.

Here is the result when you want to remove the battery, the connector is completely damaged due to the heat

It's been now 6 month since I opened my tablet for the first time.

As I said in a previous post : opening the tablet, unplug en replug battery solved me the issue.

But it worked for a month (which is better than nothing). After a month, flickering started again.

So I opened it once again and unplug/replug battery : it worked for some weeks again.

And I do that everymonth.

But 2 month ago, I decided to change battery (26$) and since I did that, no flickering.

I believe it won't last because the real cause is, as mentionned : you need to solder the battery connectors.

The hardest part for me is to find someone who will do that. I contacted many repair center and no one has balls to do that (if I had tools I would do that by myself).

DON'T HESITATE TO OPEN and unplug/replug, it's easy, and you can work with your tablet while waiting for repairing....

What do you have to do to make the connectors tighter?

I've noticed on mine that it does happen when battery is below 50 %.

Last night it happened when I was watching youtube video,I wanted to change the resolution,got that white popup window and screen immediately started to flicker when white popup was overlayed over video.

Last time it happened watching yt videos too,and even it rebooted few times.

I just hope in my case it's software related but dunno how to resolve it.

Update:

In my case screen flickers at the boot and when I touch it.

Then in few seconds it reboots.

Issue happens when battery drops at 50 %.

Anyone had that kind of case,and was able to resolve?
