I don't think you can find it online. Re solder is sufficient, no need to replace a new one.

But why you need a new connector ? Broken or damaged ? If you need one I may help you where to find it, but change this connector is not simple as re solder unless you know how and have right equipment like hot air gun, hot plate ...etc....

in a worst case scenario.

As of now, things are fine. The tablet is working fine even on longer duration of usage like playing videos on YouTube app continuously or video calls. The battery charge is lasting long besides there is no overheating like it happened before when the connector was loose. Thanks again.

However, when the connector got detached earlier, I observed that the plastic used to design that component is of pretty cheap quality and I doubted if it would stand even before I soldered. Anyways, I managed to solder that without breaking/damaging it. My fear is that the plastic base on which the (metal) connector components were placed in side-by-side fashion would disintegrate if when the plastic base gets damaged and that is my worry. I hope you understood my point.

Also, I would appreciate if you point me to any links that would explain a little more about these components.

This connector is quite sturdy and not easily to be broken unless by a novice user.

I see many users broke this connector as they have no idea what they are doing: instead of prying up and removing the white connector, they pried up the black connector, damage the connector as well its solder traces.

Here is the connector if someone needs it

I am having the same issue- for temp fix : I noticed that tab S when used in power saving mode- doesn't flicker. This is just my observation

Can someone provide me with the real fix or only option i left is to replace battery connector or to soldier it.?

Did anyone tried doing a hard reset- According to Samsung service support, they didn't acknowledge this as a common issue and asked me to hard reset the device
[Galaxy Tab S Q&A, Help & Troubleshooting] Beut:
Even it's the truth, they are not allow to admit it or get fired . Samsung knows it very well, like other manufacturers, they never admit the defects of their product.

This is not a software problem, reset has nothing to do with it, even load different firmwares.

It is not only this model, look for topic of Flickering screen from Galaxy Tab Pro or Note Pro, they have the same problems. In Android Central Forum, this topic reaches over 100,000 views, a live truth of this problem. Search for this topic by Google, you'll see it everywhere from many forums.

Just got back mine from warranty repair: "we were unable to find the problem highlighted, but have found a different one."

In summary, they claim having changed a ci/pa/filter (?) and have installed a new firmware (well, not new, it was the same version I already had).

Well, now the tablet is no longer showing the stripes, nor randomly freezes or reboots, but battery is not able to recharge properly: when recharging, it moves from 80% to 100% in seconds, and when discharging I've jumps from ~100% to ~80% and then from 70% to 50% in seconds, for a total lifetime of a charge of 1 hour (1st cycle charge/discharge) and 2 hours (2nd cycle).

I'll keep trying for few cycles more, but I'm afraid I'll have to send it back to repair again.

Tablet back today: they changed the battery, the display (I suppose they broke it while opening the tablet) and the USB cable (?).

Battery looks much more stable now: can charge up to 100% and discharged down to 10% remaining stable and with no stripes on the display.

Err, i left the tablet at 70% this morning, in flight mode, and when coming back this evening tablet was switched off and not restarting. Had to soft reset to switch on, finding 25% on the battery (the night it went from 80% to 70%, which is not that bad, considering WiFi was on and had no time to trim sync of the various apps).

Maybe it is just a sw problem... will see in the next days
[Galaxy Tab S Q&A, Help & Troubleshooting] wis38:
Battery behavior is strange: almost fully discharged (5%) it was at 3.692V while at 100% the voltage was 4.345V. With power saving on and continuous usage (browser only, display at low brightness) it arrived at 15% in ~2 hours , with a battery voltage now at 3.998V.

OK, I made just a couple of cycles discharge/charge (battery is new) but builtin calibration should not be so far from reality.

Few months before repair (before the big troubles with the stability) the tablet was able to run 6-7 hours before running out of battery, when used in power saving mode (well, in standard mode autonomy was never better than 4 hours).

Any suggestion?

Thanks

[Galaxy Tab S Q&A, Help & Troubleshooting] Ferg8080:
I recently bought a Samsung Tab 8.4 off of Ebay to find when I'd loaded my apps on it started to have the above mentioned problems e.g. rebooting, freezing and flickering. One guaranteed way of seeing the mentioned issues was to turn off power saving mode and tap on the google voice search and every time without fail it would seize up. I have since returned the tablet to the seller but what I noticed was after doing a factory reset to clear my stuff off the tablet it seemed to work fine regardless of power saving mode. How odd?
[Galaxy Tab S Q&A, Help & Troubleshooting] Alfatoad:
I could only get my SM-T700 to act normally by having it plugged in. It was alright at the start with full chaege but the lower the batt got freezes and flicking would start. This got worse till it needed constant mains power. All software based fixes didn't work. So it had to be a battery related issue I reasoned. Opened the back up (you tube it if your not sure) and lifted the white battery connector from the black motherboard socket. Adjusting the white plug was far to difficult even a pin or needle wasn't small enough to get in there. But the 5 pins on the black are there easily accessible, so I gave each one a slight lean to either the left or right. The smallest amount.

And hey presto all working again first time in months if been able to use my tablet un plugged. So if having your tablet plugged in stops the flicking freezing... it would point to a battery issue
[Galaxy Tab S Q&A, Help & Troubleshooting] Beut:
This is a fix from Samsung repair center, they just soldered the cables directly to the battery connector to fix loose connection which also causes flickering screen.

However, they did not resolder the battery connector, the screen still flickered, especially at low battery. I did resolder all the six pins, problem solved.

There's no more flickering screen, even at 10% battery.

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

This is the original, the closed up view did not show any signs of hairline cracks. That's why most people think the battery connector's solder joints are fine.

However, if gently pushed, it will move.

[Galaxy Tab S Q&A, Help & Troubleshooting] Alfatoad:
I never even looked at the solder joints. So possibility my method of leaning on the pins to the battery transferred force to the rear of the socket. So the issue may reoccur and soldering will be the final solution.

But so far so good.

Hi

I am completely new to this forum. I am not a software developer but I am an electronic service engineer by education. So soldering is not uncommon ground to me. I have been having the flicker/random restart problem on my SM-T700 for months, just getting worse and worse. I had searched hi and low and until now only found descriptions of how to clear the caches etc. I had installed a custom rom, same problem. I had suspected the battery but battery time actually seems ok. I found out how to open up the tablet and disconnected and reconnected the battery, as I found hints it could be a bad connection in between the two parts. Here I thought I had fixed it as it worked fine again for a little while. But of course the problem just came back.

Finally I found this thread which pointed in the direction of the solderings. So once again I opened up the tablet to inspect the connector closer. I took some macro photos of the solderings, and it doesn't look good. You can see the pictures here. The difference between them is primarily the focus point:

I will now go to my work place (I am actually on holiday) where I have access to some soldering equipment to re-solder the connector.

[Galaxy Tab S Q&A, Help & Troubleshooting] Prostheta:
I haven't needed to do any sort of soldering work to my Tab S2 8.0 yet; I think the best way of doing a more non-destructive test repair is to carefully prise up the sides of the white connector until it can be lifted off, then using a pair of tweezers, lightly bend the six contacts in the black header alternate directions. Literally less than you can see; they need to be straight of course. Refitting the white connector means that if it was a poor connection within the leaf contacts within the connector, this gives them a fighting chance. In my case, everything is now perfectly fine. I opened YouTube, whammed the brightness up to full and zero flicker, glitch and reboot. It worked for me, so before you try something you can't undo, consider this I guess.

In order to fix loose battery cables, there is no need to take them out of the connector. Use this conductive glue , one 0.2 ml syringe is more than enough to fix the cables.

http://www.ebay.com/itm/3X-Silver-C...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649

This is the original connector

[IMG="Original"]http://www.mediafire.com/convkey/eb9e/irbfv80x3r9vx2n6g.jpg[/IMG]

Then apply this glue, smear it evenly and deeply to six cables, then wipe out the excess with alcohol to avoid shorted circuit.

Make sure the glue is clear between two adjacent cables.

[Galaxy Tab S Q&A, Help & Troubleshooting] Tinderbox (UK):
Never had a battery or flicker problem on my 10.5" in over 2 and a half years and i use my tab every day, I am sure flexing/accidental dropping loosens the battery connector as their are a lot more 8.4" than 10.5" affected, I have my 10.5" in a solid skin/case so no flexing and when not being used it`s in a zipped up hard case.

I remember one 8.4" owner saying that when he open his, the battery connector that is soldered to the motherboard was totally loose and had broken away, I dont know how the S2 or S3 do the battery connection, I might have a look and see if Samsung did anything different.

EDIT: It looks like the S2 uses the same type of connector.

[Galaxy Tab S Q&A, Help & Troubleshooting] aktacosa:
I have been reading this post for several days trying to figure out how to fix this problem, and I've done everything short of soldering the battery connections (I used a macro lense to inspect them, and they weren't bad), and I had almost lost hope but I wanted to try one more thing. I have read from several sources that it was unconfirmed that this was caused by a software issue, but I was willing to try anything. Typically there is no give, and no warning, once my battery (which I just replaced) would reach less than 30% was when the problems would start. The only way to avoid it was to recharge the tablet above 30%, but when I would go to charge the tablet, it would start charging at 0%! It was highly annoying mostly because I just replaced the battery.

Here was my method for a possible fix, I used Cf-Autoroot (link found here on XDA) to root the tablet with Odin (supplied in the zip file), then downloaded the Lineage OS klimtwifi ROM for the T700 from XDA and flashed it along with GApps Pico. I haven't had much time to do any real testing, but so far my battery has reached less than 30% twice and I haven't experienced any glitching, or random restarts. So we'll see what the future holds. I wasn't expecting much when I bought this tablet used at a Goodwill store, but it really is a great tablet, and it's very functional. With this update you'll be on 7.1.2, and there are nightly updates that can be downloaded and installed from the device which is a nice touch. The only thing I miss is the fingerprint sensor. It doesn't function properly within the ROM, but it's not a deal breaker. I hope this helps someone. Let me know if you have any questions.

EDIT**

Through my testing I have figured out that it's not software. The tablet still froze and shut off but at 10% battery this time. After putting on the charger it still started at 0%. So disappointing.
[Galaxy Tab S Q&A, Help & Troubleshooting] adibadi:
I underclocked my Tab S 8.4 to max 1.5GHz and all the flickering/restarts stopped, but now it runs annoyingly slow (not that it was blazing fast at 1.9GHz). So if you're rooted, this could be a temporary solution. Next I will have to inspect the connector and probably solder it. Not in a big hurry though because I got a Mediapad M3 to replace this.
[Galaxy Tab S Q&A, Help & Troubleshooting] aktacosa:
How do you do that?
[Galaxy Tab S Q&A, Help & Troubleshooting] adibadi:
I used no frills CPU app from the playstore, set max speed to 1.5.

I have since opened the tablet and squeezed the battery female terminals a bit closer together as suggested earlier on this thread. So I set my CPU at full speed again, waiting to see if the problem comes back.

[Galaxy Tab S Q&A, Help & Troubleshooting] aktacosa:
I bought the Tab S 8.4 T700 at a Goodwill store for a steal for $59! I don't think they knew what they had lol. After charging it all the way I noticed that it too has the screen flickering issue after updating to Marshmallow. I summed it up to it came from a second hand store, and it was pretty beat up when I bought it but I wanted to see if I could get some life out of it still. So I performed a factory reset, cleared the cache, and did everything I knew to do with any Android device that could potentially have issues after a firmware update, but no luck. I called several cell phone/tablet repair shops in my area but they weren't willing to look into the issue, so I was on my own until I found this post and saw that I wasn't alone. The biggest symptom I was having was that the screen would flicker and go nuts when the battery would get below a certain percentage (~20%), then it would constantly boot loop until the percentage was above that. After reading this post in its entirety I did end up changing the battery, I also checked the terminals, and the connections and after looking at them practically under a microscope I found that there was nothing wrong with any of them. So I kept searching.

I kind of fixed the issue somewhat by putting a custom ROM on it by LineageOS (gorgeous ROM running 7.1 Nougat), but it still craps out if the battery gets below 10%. I've followed this post very closely for other solutions, but I'm still at a loss. This a great tablet, and I don't need it for any particular reason other than just for entertainment, but the end doesn't justify the means if this issue persists. This tablet even refurbished is still around the $200 range on Amazon, but I found that Amazon also carries the motherboard for this tablet for about $70 for the 16GB version (which I have). Does anyone think that switching it out would help?
[Galaxy Tab S Q&A, Help & Troubleshooting] Beut:
Change new battery or mainboard won't solve the problem as they have the same issue of battery connectors: white of battery and black on mainboard.

Call repair shop won't help you, they will charge you to replace the LCD due to flickering problem, and believe me or not, they have no clue how to fix them.

Try whatever you like, it won't go away unless you need to fix 2 major problems:

1- Resolder the battery connector.

2- Fix the loose connection on the white connector.

I already point to the right solution but many people just don't understand it and try something else not related to the flaws in Samsung tablets.

Just want to contribute to this thread. Like everybody here, I have experienced the screen flicker, then loss of signal, then flicker again then crash/reset of the tablet when my Tab S LTE 8.4 isn't connected to a charger. The problem is much worse if I'm using 4G mobile data. I've tried almost everything except for soldering. Even tried opening up the back and pushing the pins together to no avail. Pushing the pins only fixed the problem for half a day before the problem comes back again. The battery has also been replaced years ago (1 year after I bought it) by a third-party before which only temporarily solved the problem.

I have finally found a solution that seems to have worked. I underclocked the CPU from a max of 2100 MHz to 1900 using a generic CPU overclock/underclock app. (the app I used specifically is called Quick CPU Overclock Lite). I have owned this tablet for years and this is the only solution that has so far lasted more than half a day. I am about to do further testing but I am typing this message now on this tablet. Before the underclock my tablet would've crashed hours ago ago if it weren't attached to a charger.

Will be testing to see if I can drain the tablet's battery to near zero without crashing. I'm at 60% and going strong when previously I was crashing at 88%. No flicker, loss of signal, crash whatsoever. I'm gonna see if I can push the underclock to 2000 MHz but I'm already very satisfied with the results at 1900 MHz. This tablet was borderline unusable without a charger before, now it's perfect again for studying and web surfing.

If anybody else still owns a Tab S this 2020 and still experiencing this problem, give it a shot. Lol.
