Samsung Note Pro 12.2: Screen flickering problems

[Beut]

Be aware that the wires inside the plastic battery connector can slightly move right or left, that's why they could make better contact when you reconnected the battery. However, they can loose again later on by the movement of your tablet.
That 's why I said what you did is not a permanent fix.
This is for your reference how to do it

Open the back of of your tab4 unplug the battery and press the power button then plug the battery back in and close it up restart it and problem solved . I found out its a charging issue it messes wuth the battery but this procedure fixes it . Hope it helps Cheers

Or... what you are really doing is reseating the loose connection that Beut (a trained technician) keeps referring to...a temp fix if that's all you are doing.

I have been having the same problems and wanted to see how to go about a class action lawsuit or a petition to recall the device. I have the flickering screen, power off in the middle of using the device, I also experience shut down whenever I use the screen mirroring feature, also battery charing intermittently. I just purchased this end of Jan of this year. I will be filing a BBB complaint if I continue to get push back from them.
hope this helps!

Would conductive epoxy stand up to the heat and flexion better than solder? I think it would be easier for me to work with than soldering because I can cut out a piece of cardboard to sit over the lines I want to repair.

This damn flickering is been plaguing me for a couple of years now, and it had evolved into a no-charging issue, right after school starts...

Epoxy may crack with any amount of flexing as it sets up pretty hard. But you can try. Let us know if it works.

A customer had this problem on his tab pro as well.
The screen dims when CPU is downclocking, and not when working hard as you would expect.

Resoldering the back of the battery plug on the motherboard and also overflowing the solder point a little.
(the factory always add the absolute minimum to save money)
Also added a little solder on the pins on the mobo connector side to "fatten" them, solved the problem here.
No modification to the plug itself.

It's a fix I've used a lot of times, leaded solder is permanently soft and naturally anticorrosive, unlike the silver glue they are supposedly using.

Thanks for the solution. =)

My 12.2" is doing the same sort of thing: the battery discharges quite quickly and when it gets down to around 25% the thing just keeps rebooting constantly until I power on plus up volume and select power down. That's the only way I can get out of the reboot loop!

There's no video in post #72. Besides, thanks for all the tips, but dou you guys really think it's no big deal to solder connections which are about 1mm apart? That's a typical problam of most forums sadly.

It's not difficult but without microscope or magnified glass, it'll be hard to do, especially with novice.
Your chance of mess up other components with solder bridge is likely.
.
These videos are for Samsung Tab 3, but it's exactly the same as in Note Pro or Tab Pro.
This battery connector used in different Samsung tablets so there is no difference how to resolder it. However, the level of difficulties is different depending on your model. Note Pro has more components close to the battery connector than other models, this rework is not an experiment for novices.

Untrue. A loose connection is not the issue and or the only thing your accomplishing here by doing so. You also clear all electricity from the devices components, specifically discharging the capacitors on the mother board.

All said, ... by running a battery repair app to fix any bad sectors, running the battery completely dead, disconnecting the battery which wasn't loose and holding the power button for 10 seconds, reconnecting the battery & giving it a full charge before powering on I have not had a single flicker happen since, which my device had flickered horribly under 30% battery power.

The trick worked.

My VZW Note Pro 12.2 is now 3 years old and has the same issue with flickering and constant restart at battery levels below 60%. It works fine when plugged in. But obviously useless for any travel related usage when the unit can't always be plugged in.
Few questions:
(1) How much do you think it might cost if I decide to fix it. Keep in mind I would have to pay R/T shipping plus fees. Would you say $300?

(2) I got a replacement device from insurance which is a Galaxy View. A quite radical tablet, that is really a smart HD-TV with android functionality.

(3) How much do you think the insurance will charge me if I decide to keep my banged up and 3 years old Note Pro and not return it?

Tnx,

 

[SHIVA77]

don't all of you respond the same time.
I am keeping my old device, the Note Pro 12.2. It will come in handy, even though it doesn't really run on battery below about 65% charge, which means it needs to be plugged in all the time.

 

[SHIVA77]

Anyone knows if a battery swap, specially with an aftermarket brand like NewPower99 will eliminate the flickering problem?

 

[Beut]

NewPower99 is third party battery, overpriced, and no better than OEM battery which is under $20.
Many users claim new battery fixed Flickering problem but they don't realize new battery has a tigher connection than old battery. Even new battery won't fix your problem if you have cracked battery connector.
This is not a guessing opinion, read my previous posts you may understand what I'm talking about this flaw in Samsung tablets and how to fix it. Try whatever you like and you'll see if I told you the right solution.

 

[SHIVA77]

Hi, First off I agree that the NewPower99 seems to be overpriced after I read bunch of comments on Amazon and compared with another vendor selling battery for $24 who had better comments.

Yesterday my tablet went all the way to 28% before flickering and shutting down (used to do that at 68%). That was pretty amazing. Now sure what happened but I did check on Turn Off Hardware Overlay. But if my problem gets worse I'll buy a replacement battery. Tnx.

today I tried folding up a piece of thick paper and sitting it above the connecter. I then put the back panel on so we'll see.

This is what I ended up doing - I don't have any soldering experience.

I had the flickering and rebooting problem. Hadn't seen this thread. Bought a replacement battery, which worked for a couple weeks, then suddenly didn't. Then neither battery, nor any type of power charger, could even get the tablet to boot (galaxy note 4)

Found this thread, and discovered that pressing down on the battery connector fixed the problem. So I folded up some newspaper and taped it to the battery connector and put the back cover on.

Not an ideal solution and potentially a temporary one. There's a bulge in the tablet, and pressing too hard on the screen causes that small square to discolor the screen.

If anyone can suggest a better solution please do. This is a repair for a family member, and they live far from me, so I would like to get it right

 

[SHIVA77]

Which replacement battery did you use?

Which replacement battery did you use?

EB-BT330FBE

Currently I have the original battery EB-BT330FBU in it and it is working fine (with the newspaper wad pressing into the battery connector)
