Please help! Galaxy Tab S glitch.

So, I got a Tab S a couple of months ago and then about a month ago I started having some trouble with it. Lines flashing down the screen and the screen turning off. I'd have to lock and unlock to get the screen back on. Sent it to Samsung for repair and they sent it back about two weeks ago saying they couldn't find a problem. Well, the problem is definitely still there so today I took a video. Samsung said I would have to send it back in for more tests and that they would not watch the video. I'm afraid they're not going to find anything again so I was wondering if anyone had a similar problem and could help.

That's the video, remove the spaces

Does it still happen when you use power saver mode?
When the display goes blank, you press the power button twice, once to enter sleep mode, and again to wake it up, so it looks like a loose display connection or a faulty display, does the screen ever come back on without pressing the power button.
Does the brightness level effect how often the display goes blank?
John.

Thanks for getting back to me. It does still happen on power saving as it turned that on not long after I took the video. Screen brightness I'm not sure though because I packaged it back up to return or send for repair, whichever I decide is best to do.

This happend to me 2 times in the 6 months I have the tab s, seems more like a software thing for me.

All you can do is a factory reset, then install no apps (in case they cause the fault) and see if the problem is still there, if it is, all you can do if you are still in warranty is get an replacement or repair.
John.

I've got the tablet back out of the box while I wait for my repair packaging. I did a factory reset when I got in from work and restored a backup and straight away I had to the same problem. I've now done another reset but with out restore, I haven't even logged in to my Google account. So I'm thinking it's either an app I have installed, not that there were that many or some of the factory installed apps I disabled/removed. I don't think the restore from backup reinstalled apks such as remote play and show box so they can't have been the problem. Could deleting any of the factory apps cause any problems?

You can only delete factory apps when you are rooted, any you have delete without root will make no difference to your tablet stability, try and use the stock apps and see if the error shows.

I've disabled a couple of them like New York times and the office suite one. It's working faultlessly at the minute. The problem is when it came back from Samsung it was working fine for about a week and then the problem returned so I can't be sure if I've solved anything or its just a ticking time bomb.

I don't know how Samsung tests the tablets, they will just send it back if they cannot find a fault, download a couple of benchmark apps, to stress your tablet and see if the fault shows up, see if increasing the brightness while benchmarking doe anything.

Just ran Geekbench 3 adjusting brightness from lowest to full and nothing, worked fine. I'm at a loss, I know that if I send it back to Samsung they're not going to find anything and spoke to Very today, they won't refund me without Samsung authorising it.

Is that Very UK, if so they send phones and tablets for repair, if they cannot repair your phone/tablet in 30 days they give you a refund unless as you said the manufacture says to refund.
Hopefully your problem will not show again, but it could have been an downloaded app, or an update to an stock app that causes the problem only time will tell.
I suppose you are on lollipop, I decided to stay on Kitkat as it`s super stable for me.

Yeh it is, but I bought it a couple of months ago. And they've have to find the fault first.

Hello i have similiar kind of problem i mean it shows stripes and boom reboot or sometimes screen goes black.I wonder if you found any solution?

Have you done a factory data reset from the settings menu, you will loose all internal user information so backup first.
If you have done an reset and still have the problem and you are on the stock rom and have not flashed an rom and have not rooted then you have an hardware fault.

Yss i did it 2 times didnt worked.Weird thing is when i open powersave mod its not happening maybe i should use powersave mod always meh

If you are out of warranty check the battery as it sound like an bad connection or a bad battery, there are guides on youtube on how to get the cover off the tablet, you can buy a kit from the link below for $65 or cheaper on ebay for the battery and pry tool.

Note 4 rebooting randomly then not booting fully.

This is a serious problem. In the past couple of days, I have been using my note 4 and it reboots out of nowhere and will not boot again. I tried wiping cache, no dice. Tried factory resetting it, no dice. Used the Verizon official software repair tool, no dice. I even flashed it manually with ODIN and used a PIT file to re-partition it and that fixes it for a couple of days, but then it does it again.
Nothing will get the device to boot again, and it will not boot into safe mode either.
Does anyone have any idea as to what on earth is going on? I've had to put my SIM card in another phone that works.

Hello Macmaster2000, tried using another battery?
My current note 4 situation, though some battery/charging apps say the battery is "healthy".... when its not plugged in it will go into a boot-loop after about 1-2 hours of usage on battery even if it had 80-90% of battery life and it would still boot-loop.. but when it is connected to the charger it wont boot-loop..
Sadly, I don't have a replacement battery to tell you if that's the problem to my bootloops or other :\ worth a shot thou!

:highfive: No problem glad to be of help! :highfive:, my batteries came in(I've ordered 2 off amazon due to a bad past experience with my old nexus 4 when i ordered one. was a month without a phone . one from BinTek and the other sais its OEM but i say "yea right" as long as it works ) and as well it solved my problems! I just wish I Didn't factory reset my phone :crying: back to square one again ah well live and learn.
another thing to take a "note" of ; =D when i've reinstalled 5.0.1 i had a crash message along the side of "NFC crashed failed to respond" maybe our batteries aren't actually "dead" maybe faulty NFC chipet or whatever on the battery preventing it from staying alive (i truely dont know but this sounds suspicious..... it could be that our batteries were bottomshelf.... or.... *looks at samsung* )

I think the best batteries are from Anker, best sellers on amazon and I've never had a problem!
Also, not sure on the NFC crashing, I use it daily and haven't had an issue.

Another attempt to bring Note 4 Back to life (ATT - Unlocked after contract was over)

So experts,
Currently I am on S7 but I do miss my Note 4.
After Marshmallow update it started lagging, shutting off etc.. all known problems. To fix it I downloaded wake lock app and it worked fine but drained battery a lot.
I tried to flash it through odin etc... (not a technical guy I am, followed instruction from one of the threads on this forum).. took all the files on SD Card and after that phone never turned on.
It does not charge, no LED lights when plugged in, none of the buttons are responsive. I have tried everything like new charger, usb cable, PC, new batteries etc...
1) Do you guys think It's hardware problem?
If No then,
2) Is it possible to fix it and how?
Please note: Phone does not turn on or recognized by PC. If it is just software problem then I am determined to fix it. I may need instruction for even very simple steps.
Thanks in advance to all!

Bump....
Anyone?

Sounds VERY similar to the problems I and others have had with hardware. I sent mine into repair, and for a flat $74 fee, Samsung reported errors with the charging circuit, main board, camera, etc. They replaced darn near everything on that phone, all for $74... Well worth it, in my estimation. Phone still performs better than today's $400 phones... Call samsung and they'll set you up. Had the phone back in under 10 days.

Oh ok. I better do that if it is getting resolved in $74. For some reason I am not able to adjust to Galaxy s7, been on it for 6 months now I guess.

I switched to cricket several months back, and have had relatively few issues until I downloaded an ad blocker. then I started having the freezing rebooting stuttering ect.
I tried to do a factory reset, and It got into a boot loop. Somehow I managed to get it booted properly clearing the cache.
I don't know why But it is almost like I somehow got new features after wiping. With s note, and a popup hitting the home button.
However
the freezing and reboot issues are still occurring. I had none of this till I downloaded the ad blocker.
Its currently on 6.0.1 baseband n910aucs2epk2 kernel 3.10.40-8932341 Build no mmb29m.n910aucs2epk2
can I try reinstalling the update, I haven't had one since switching to cricket. I assume I would have to instal it through sd card.
And When the second poster said to contact samsung for repair. Will they fix it if you aren't the original owner?
And specifically who am I looking to contact within samsung?
thanks

Don't know all the answers but I did contact Samsung. They have walk - in centers, just google it, contact the one which is near to you. You can either ship the phone to them or just walk in. I have not confirmed about the cost of repair yet!

Had word with Samsung repair and they said the max they charge is $199. Anything more than that is beyond economical value so they don't suggest to do it. visitng them this Saturday. Will update.

I visited Samsung walk in center today. In my case they refused to repair it saying that the issue is Motherboard (without even checking, but he seemed vary confident) and the repair cost is more than the price of new phone as of now. I tried to convince him to check at least. Disappointed I am, honestly! but this visit was like final nail in the coffin.
How did you convince them to do it all for just $74?

Call Samsung customer service, they've been great to me.

Samsung did fix it for $70. Phone looks fresh and new now! Great service. Thanks for your suggestion!!
Now I am confused between s7 and note 4. S7 has good features like finger print (very accurate) and samsung pay (brilliant) which is missing from Note4. But I may still switch to Note 4.

Redmi Note 8T app freezing

I bought my wife a Redmi Note 8T for xmas, and unfortunately it's been an absolute nightmare to operate ever since she received it. It works perfectly after a reboot, but after a few hours or perhaps half a day of use many of the apps on the phone refuse to open, they just display an all white screen or sometimes the logo of the app, but never open fully. You can close them, or press the home button to go back to something else but that app will not open unless you reboot the phone again.
I did multiple factory resets and re-set everything up but the problem always comes back. I ended up returning it to the retailer (I'm in Australia but the retailer was overseas), but they insist they couldn't re-create the problem, and refused to tell me if they were actually using the phone for a few hours before trying the apps...they seemed to be only ever trying it out after a reboot. I won't name the retailer but their customer service is extremely poor and I certainly won't be using them again. In the end I asked them to send the phone back to me, at which point they demanded $70 to return it as "there were no issues found". I paid it, got the phone back and then cancelled the charges on my credit card just to annoy them.
Anyway...I got the phone back a couple of days ago and set it up again from scratch, MIUI 11.0.5, added my wife's google account, installed half a dozen of her apps (FB Messenger, Whatsapp, Bring shopping etc)...she used the phone for about 2 hours then Messenger and Bring refused to open with the same problem. I can only imagine it's some kind of CPU or RAM issue. It's the 4gb/64gb model so it should be very capable of handling such a light load. Model M1308C3XG.
I figured I'd cut my losses so went and bought her the Mi 9 Lite from a local retailer yesterday morning and it's been working perfectly ever since. Cost twice as much as the 8T but at least I'm not copping an earful any more!
So...I have a new 8T that's has nothing to do....figured I might unlock the bootloader and try TWRP, see if it makes any difference. Did the unlock last night but it tells me I gotta wait 168 hours. Sigh. Anyone got any ideas in the meantime feel free to throw them my way.

Hi Bro.
Me also facing this problem. I am using redmi note 8 (Indian verison)4/64GB variant
I faces the the same problem u mentioned above.
Me also reseted the mobile but the problem still occurs.
Also me unlocked the bootloader and installed the original fastboot flash ROM. But still the problem occurs.
I don't know how to solve this problem.
If you got some solutions suggest me....

I never did get it solved mate, but you know what's interesting is that I can't recreate the issue without a SIM inserted in the phone. I transferred the SIM into the new Mi 9 Lite and it's working fine, and I have been playing with the Note 8T without a SIM...the issue hasn't come back. So my guess is this is a fault with the GSM hardware in this model of phone...it might only happen if you're using a certain frequency which is why not everyone has the problem?

Hi, I'm having exactly the same issues, even though I changed ROM. Seems like a hardware issue. Did you manage to fix it?

Question Regular, repeatable shutdowns

Someone please give me hope.
I've got this phone yesterday and it keeps turning itself off when locked. If my phone doesn't receive a "wake up signal" like a notificationn or isn't in charge it will turn off in around 5 minutes (measured with a clock). This is not a sudden shutdown or crash ,you can see the logo on the screen.
Neither safe boot nor factory reset solved the problem.
Returning it and buying it again at the same price is impossible now so i'm hoping for a fix before the return window ends.
Can Xiaomi fix my (and probably others) phone in less than a month or is better to throw the towel now and go for a full refund?

Oh.. Had a few unexpected shutdowns Yesterday.. and one today.. but it's Not reproduceable.
Have you tried to enable AOD? Maybe this is a workaround....

Yeah, even with AOD permanently on after around 5min the phone shuts off. I've also tried running the clock app in chrono mode in the background with no results.
Rightnow i'm trying to reinstall miui 12.0.2 cause i don't understand if this is an hardware problem or a software one.
Also we don't know how widespread this problem is, a lot of people are happy with their F£ but it's impossible not to notice a problem this serious

Just ordered the phone, will come in a week, what version of MIUI does it come with, Global stable or Global beta?

Bro try unlocking bootloader and installing xiaomi.eu

I have the same problem. Got it yesterday, went to sleep and in the morning the phone was rebooted/crashed.
Had to put in Sim pin and Device pin again just like after a reboot.
I hope this gets fixed soon.

Same problem here, I have the f3 for ten days with MIUI Global 12.0.4 (Italian Country), several reboots (four) almost always at night under charge, but once even during the day in front of my eyes, another time I have found the smartphone completely turned off, at this point I don't know whether to ask for a refund because I don't know if it's a SW or HW problem
There are several users who are reporting this problem

Hmmm i think the update from yesterday solved the problem for me.
I didn´t have a reboot this night.
Edit: Had another reboot this night, so update didn´t help.

UPDATE: i've updated the phone to 12.0.4 and the problem still remains. i will ship it back to Amazon in a few days. Also the problem got even worse ( before update): it's the second time i've found the phone with 0 charge after one of those shutdowns. The "when isn't in charge" part of the OP is also wrong, in the last days the phone switched of even while charging

Had a reboot this night on 12.0.4

Before putting it definetly inside the box after factory reset i've tried to start the phone again and then lock the screen at the welcome page. After 10 mins i've found it turned off

Same problem for me. I wonder, does it also happen on xiaomi.eu rom? Hope its not a hardware fault.

Pretty sure it´s just a software Problem. During my search for a solution i found out, the Poco x3 had the same problem.

That can't be, if it was a software problem all of us on MIUI will have the same experience. I think mine is a hardware problem cause is worse than anyone here. Also a lot of people do not have any problems so maybe is a QC issue on some component like the power management chip

I dont have any shutdowns or reboots at night, but i use an old charger with 800mA.
My Shutdowns come If i disable AOD.
