Note 3 stuck with Samsung logo - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi,
I have bought new Samsung galaxy note 3 last month and my first samsung product.
Within 3 days it started to trouble... When plugin for charging, it is automatically started to reboot continuously and only after unplugging the charger it will restart to normal. Tried with couple of other chargers and the same issue persists during charing.
So far I have been using apple products and my brother also used to go for apple products. My brother insists to go with iPhone 5S and I want to try a new product with samsung which gone in vain though everyone might won't have this issue.
Okay..patiently packed the 2 days old..sorry should be new phone and went to samsung authorized service center traveling for 1 hr and waited for 2 hrs. I have took the video of the reboot problem and explained the issue. They got the phone and it will take 1-2 days or collection .Gave the phone to them and travelled back for another 1 hr and half a day gone.
After 2 days got the call from service center to collect the phone...during office hours with lot of excitement to use new phone took permission and travelled again for 1 hr and waited for 2 hrs for collection.asked for the problem and they have told some charging unit has been replaced.
happy back to home...put it for charger and after 20 mins I have gone out and came to room to see the same rebooting issue continuously.
no time to go to the service center due to office work as it will waste my 4-5 hours. waited for Saturday and almost for 6 days it has it been not used and inside the box..my brother started to tease me and so far using iPhone for 6 years with different models and for at least 1 year no issues... ok patience...
gone again to service center and blasted them but what use and they got the paper waiter ( that's note 3) and this time they told it will 1 week for complete checking... what to do gave them and returned back for the 2nd time.
new phone for $900 and used only 2 days...after 4 days got the call for collection and I have asked what is the problem with the phone and they have told they have replaced the mother board itself...great..I have asked to write it clearly what has been replaced in the service request form and it is what written "RPL PBA (4.4.2)"
at last started to use the new phone after 10 days and I am happy the issue is not happened again...but now after 20 days it started to have different issue... this time the Samsung logo displayed and you can't to anything...once tried with pressing the power button and it is rebooted... happened again after5 days and this time even pressing the power button didn't helped...after 30 mins I have tried again to press the power button thought of trying it before going to recovery mode and this time restarted...
this is not rooted and don't have any SD card and installed only minimum apps...and suggestion why this note 3 stuck with Samsung logo? do I need to go to service center again....
it is still with samsung official OS..below is the details
already having 1 yr warranty and thinking for paying for 1 more year...

Android version: 4.4.2
baseband version: N9005XXUENC2

If u want easy, bring to service center and blast them
Uf u want to test urself first, try to go into recovery and do factory reset nd wipe cache. Why?
Ur phone might did an auto update, and might did an auto reboot after that.
If still cannot, u may want to try to reflash stock official firmware.
If still fail, try to send back to service center.

Hi..Thanks for your reply. But I haven't checked for auto update. May be I will monitor for some more days if this issues happens again or not..when I am in between the office work...this type of issue is very irritating. . Unable to call or message. .. Such a pain....Doing all kind of repairing in office. ..

Is my Nexus 4 Dead?

Well it appears my nexus 4 has died mysteriously. About a month ago battery life went to **** and it started rebooting at random intervals. Tried a factory reset with no improvement. As of 2 weeks ago my phone would only operate for about 1 1/2h on a charge, and would often reboot whenever I opened an app or something. I'm away visiting family right now so I've just left it on my charger at almost all times.
Today when trying to answer a text my phone rebooted and now it won't go past the boot screen, plugged in or not. Opening fastboot works, but when I open recovery mode from here it show a picture of the android with a caution symbol over him. I took my case off to swap the SIM into my old Nexus S, and on the bottom right corner the bezel has popped out.
Is my phone done? I broke my screen in Feb and had to send it to a LG authorized repair shop, so is my phone even under warranty? Would me personally swapping the battery be of any benefit?
Thanks for your advice.
Yes it still should be under warranty.
I did the same thing. I broke the back of my nexus and had to send it to the official LG repair facility in TX for out of warranty repair.
2 weeks later I had issues with the proximity sensor not always working. Called google and set it up for a in warranty replacement.
Google shipped me a new nexus and put a hold on my credit card. You have to send your broken device back within 21 days so you wont get charged.
The adress Google had me send my broken in warranty phone to. Was the same adress I sent the phone to originally for the out of warranty repair fix. Since LG did the repair of the screen I'm sure they stand by there own work.
Just make sure you tell google you already had it fixed, and that you used the official LG repair facility in TX.

I'm in the U.K. and have the sim error problem. Phone has never been rooted always on stock.
1st occurrence within 3 months ownership but it got to a point, after a week, where it always read no sim even after restart. Samsung warranty repair changed mother/main board.
Phone was dropping calls after the warranty repair so went back to Samsung. Warranty repair 2. Changed 2 wires, don't know which ones. But now phone was working fine.
3 Weeks after repair 2, the screen went black. I could still hear all tones etc but no screen so can't answer calls (most basic function of phone). Samsung put new screen and another new main/motherboard. So now this is the 3rd mainboard. Phone came back on 2/10/14 after the repair. After 2 days I have again got message about 5 times at a time but restart is solving it for now.
So I think the problem lies in the faulty mainboards Samsung are manufacturing. Why? Because my 1st board failed and eventually always had the message no sim inserted. The engineer report said main board was changed. If it was too do with a faulty sim tray then wouldn't they have fitted one of those instead. 2nd board worked fine even though calls were dropping. This board was in phone for 3 weeks until screen got changed so I'm presuming had to change board along with screen. The latest main board which is apparently new has lasted 2 days. Like I said above its only happened a few times so far but I rather it happen all the time so I can send it in again.
I have spoke to Samsung UK escalation and they said if I require another repair then they will take it higher up but even with an exchange what is there not to say new/refurbished S4 wont be faulty down the line.
What is Samsung doing about this, absolutely nothing. My worst ever experience with a phone and I got a s 1,2,3 which all still work not even a glitch. Will buy another phone but keep fighting for a resolution with this one. Still has 17 months warranty.

Sudden shutdown

Hello everyone,
today I had an issue with my 6 days old Note 4: I put it in my trouser pocket. After I while I wanted to take a look at my news and found the device had shut down...
Okay, You may say that I might have touched the power-off-button, but as I tried to start it again there was no reaction...
At home I took the bayttery pack out and put it in again. Then it started again.
I'm a little bit uncertain what to do: should I wait if it happens again or exchange it against another Note 4 at my seller (they exchange directly in the first 14 days)?
Did You hear that this happens to more devices?
- Battery was at 90% and the device is not rooted yet.
Thank You in advance!
What i will do is factory reset and then observe for a few days if it will happen again. If it happened again, it must be a hardware problem. If there's no more time because the 14 day limit is almost over, then i will have it replaced immediately.

S7 Edge completely dead

Hello everyone,
I've got a huge problem with my s7 edge. It started betweend first and second week of usage of my s7 edge, phone got totally freezed and only volume down + power could do something with my phone. After few weeks later, freezes were very annoying, very often (2-10 times per day) and it took longer to reboot my phone. I decided to download oficcial unbranded software from sammobile, I've flashed my phone with 5 files using odin and do full wipe. When my phone booted it was ok for maybe 2 hours and again, freeze! Ok, so press volume down + power... It boots! But after few hours later, (phone was 80%+ battery) I tried to check recent notifications, took my phone, pressed power button... and nothing happens. Trying to hold volume down + power for longer than 10s and also nothing happens. Phone is not charging and when connected to computer, I can hear a sound that something is connected, but windows says that my device is not working properly. When holding volume down + power, I can hear again sound of disconnecting and connecting device again. It's now almost 24hrs from this freeze. Phone is completely dead. After I got up from bed, pressed volume down + power again and I saw GALAXY S7 edge on my screen, but again, freeze and nothing happens for maybe 10 minutes, so again, volume down + power and phone is dead again. Nothing happens...
If you experienced simillar problem or have any solutions, please help!
Cheers!

Since flashing a new software didn't help then it is definitely a hardware problem. If it is a defective unit then it should be repaired or replaced for free by the repair shop, assuming you haven't rooted your phone.
I haven't rooted my device, only flashed with latest official not branded samsung rom. I left it to my carrier on warrianty, waiting for response. Up to 2 weeks...

Had that problem with my Note 4 bro. It was a broken EMMC memory chip and Samsung should repair it by swaping the motherbord under warranty. If you Rooted it or tripped knox, like i did, than you have a problem coz they will ask you to pay for the repairs. If that happenes remind them this.. I wish i knew this before i sold my note 4 for scrap.

Good luck.
Time for small update,
thanks for links TheOne741. Cellular operator had sent my phone to authorised service, but they offered somethink like 70USD (different currencies) for repair, when new mainboard for S7 Edge is around 400$! I declined their proposal and now my phone is in other service, I want them to replace it by new one, still waiting! Hope for quick response from this second service point.
I had a Galaxy i5700 a lot time ago and I managed to install android into de SD and the simptoms u are describing are the same that happened to me when the SD had bad sectors before completely dying...
I tried removing sd card and sim card too, nothing changes.

Samsung ditched eMMC and went to UFS. while it may be a memory issue, its not eMMC.
Don't pay anything for Your phone. I've had one really sh***y service that told me the sim card slot is broken (on a device that I didn't even know that it has a sim card slot/tablet) and now I have to pay 100% same amount of money as the value of my whole tablet. That device wasn't even rooted. Nothing. I even had a sh***y insurance that didn't help me either. So I was left there with a choice of paying (device was around 100 usd) 100 usd(for a sim card slot repair that I don't even have idea if it exists, I've had phones with broken sim card slots and they were working fine) or just buy a new one. So I decided to call a "shopping lawyer"(I just payed for the call) I've no idea how to properly say that in english, sorry guys. And then the lawyer told me that I need to say that if they will not fix it on warranty then I'll go to court. Week later I got a letter that my device will be repaired as soon as they can do it, and that they are really sorry. After 14 days I got my tablet back, fully working.. well. They scratched the screen a lot so I just sold it later. Kinda sad with the scratches cause it was a really great GPS. 7 inches.. big screen.
So in conclusion.
Don't pay anything. Just use the warranty. Even if the device was rooted You have a full right to a warranty repair. And since You didn't root Your device then You're fine. It's a hardware defect and they have to pay for it and fix it.
Yup, I did not send my phone on warranty but on suretyship because my phone was only around month old! And it is obviously hardware problem, but first service tried to scam me. I have been reading tons of articles about scratching screens, breaking plastic frames, resending "repaired" laptops without few parts or even charger from very first service that my phone was sent to. And for that I took my phone away from them in a blink of an eye. Now I'm just waiting for expertise or replacement from other service.
I'm having a similar issue... hope somebody has an answer
Quick update after 40 days without phone. Motherboard is replaced. Not a whole device....
Now I want a IP68 standard confirmation. Authorised service doesn't want to give me any kind of document that confirms dust and waterproof (it should mean that my phone is assembled correctly!)
I won't sign any document that I received my phone without this.
What should I do? Where I can get any document about IP68 confirmation? Should I send my phone to another service just to confirm IP68 standard?
Once ur phone has been opened the ip68 cannot be restored unless Samsung is doing the seal.
Trimis de pe al meu SM-N9005 folosind Tapatalk
I received my phone with confirmation of all norms and standards that producent delivers. It doesn't have any signs of disassembling. Like new one. 37 days of usage and 40 days of servicing. Nice ratio
Thanks for help and information!

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"
Its a Note 4 SM-N910F, Android 6.0.1, BB N910FXXU1DPE2, kernel 3.10.40-7733605 [email protected] #1
i feel I have tried everything... History:
Phone has been working fine for a year, upgraded to 6.0.1 no problems about 2 or 3 months ago. no new apps installed. Last week it started getting very laggy, keyboard strokes took for ever to register. I thought, ok, time to to a factory reset to blow out any old cobwebs. Did it via the menu. However the phone froze midway thought. I left it for an hour and then pulled out the battery. I popped it back in and it performed the reset without me having to press anything. Cool, thats good I thought.
Now I was going to change the battery, so I powered off as normal and put my other 2 week old original samsung battery in, and it would not power on. After a few reinsertions it powered back on. I though i have to do another reset. So I tried, and it would not reset. It just died. I cant restart the phone, it dies. If I shut it down normally. it wont turn on back on, I have to take out and reinsert the battery multiple times, holding down the powerbutton between to discharge. this can take up to 10 tries now. Sometimes it will go th the unable to bot in normal mode and "downloading , do not turn of target, but it will stay there for ever, more than an hour.
Every 15-20 tries it would turn on, let me get in via pin, only to start freezing up within a min, and then die again. Somewhere I read that a guy hada similar problem, and he used wakelock and that worked, on level 4. I managed to download that and used it, and hey presto, it works!
Now I had to power down the phone for a reason, and it took me about 30 min of battery and powerbuttonholding before it managed to boot up, and I was quick enough to start wakelock on level 4.
It wont boot in to safe mode, it wont boot in to recovery mode, it wont boot in to the factory reset mode. Its the same with either battery, and different cables.
Any ideas what i can do here, or what could be wrong? I havent gotten it wet or banged it.
I am having the same exact issue on a N910A. Phone was functioning correctly and in December it started getting really laggy. Performed various resets, purchased new battery. Still laggy. Up until two weeks ago the phone was slow but now it will not power on . The phone will not charge as well.
Mine did same, 6 months old, not rooted stock firmware. Locked up yesterday, couldn't do anything. Pulled battery and restarted. Samsung logo comes on screen goes black for android boot then it hangs with blue led flashing. Nothing I do gets it past that point. Tried safe boot but it doesn't fully launch with correct button combo and volume up. In the end I re-installed firmware using Keis. All went well, everything as per youtube tutorial. Except one thing, at end of download phone didn't re-start. Still can't get it to boot, any ideas?
Edit: Lock up didn't coincide with any new apps being loaded or updates of existing. Only change was a week ago which was an automatic update of the stock firmware (Lollipop)

are you still under warranty? i sent mine to a samsung center, the guy recognized the problem as the motherboard, said I wasnt the first. That was 3 weeks ago, they are STILL waiting for the parts. They say the Samsung factory are way behind with repair parts, etc etc. I am hoping it will go under warranty. Ill update when I know!
I've been having the same problem that started yesterday morning. I've tried a few different solutions but nothings worked, I get the feeling that my phone is dead and I'm not in warranty either. I'm going to approach Samsung but my guess is they will want more than the phone is worth to repair it. I've read about so many people having the same issues, its horrendous engineering on Samsungs part considering how much their phones cost to start with

Your guess is probably correct and I totally agree with you. I seriously think manufacturers do not want their devices to be problem free for more than two years. Probably why they have stopped making phones with batteries that simply pop out.

Definitely...surely it couldn't have been that hard to make a device with a battery that was still removable on the newer phones. It's frightening how many forum posts I've found with people having their phones just brick out of nowhere (and that's just the note 4). I've given up trying to fix mine, I've tried every method I could find and nothings worked. I can only assume that this problem is simply the motherboard of the phone not working anymore. I'm not even sure what phone to buy now but it certainly won't be a Samsung.

If you do not care about the camera thera are a lot of rather affordable options which can be tossed in the bin when they start malfunctioning and if their warranty has run out. If you care about the camera being as good as the Note 4's than the range of phones you can buy is quite limited.

If you are able to boot it into Download Mode then you should Download Stock Rom file for Galaxy Note 4 from Sammobile and Flash it through Odin..
Everything will be OK... ?
Unfortunately, SAMMOBILE does not have the SM-N910A firmware.

I think the camera on the note 4 is absolutley terrible. I might even go so far as to say the pictures are unusable. the applied noise reduction renders everything splotchy, colors are off and its not sharp at all. and Im not talking dark conditions here.
Anyway, my phone was repaired under warranty and is back to working as it should. It was indeed the motherboard, so if you have the same troubles I had, those are your best bets.
I don't think replacement via warranty will be available. I will attempt to power into download mode and verify if I can get it back up and running. If not, a good ole paperweight.

Sounds like the problems I have: with my first N910F: started with lagging apps / freezing, then random reboots now and then, eventually giving error messages when booting. Finally, now it will only start after the battery has been out for at least 30 minutes, but hangs on error message. When pulling battery out and putting back in it, wont give a single sign of life. Since I was just out of warranty it has been lying around, and I bought a second hand N910F for replacement, sadly its starting to give the same errors too and is just out of warranty too (its currently still working, but with freezes / reboots / and already a event with boot error).
I read It could be memory chips or some power chip on the motherboard, appears to be a common problem. So.... Last month I bought a new motherboard on ebay (chinese delivery, 80€). Received it last week and put it back in; phone is back to life. (putting it in is a very simple task, with iFixit teardown / guide)
Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

My phone is also random Rebooting
It also shuts down at 25% of battery remaining, Have you also faced similar issue?
Download the app "Wake Lock" and run the Partial Wake Lock option. Apparently the updated software impacts the CPU. For the restarting issue, put it in the freezer for a couple minutes. You may have to take the battery out once, but it has worked for me every time.
This looks very much like the issue reported here:

There are temporary fixes (wakelock), but ultimately this is a harware issue, and the fix is a new motherboard.
I think that underlying it is a problem with heat affecting the eMMC chip or its connection to the motherboard.

Hey can u pls get me the stock firmware for n910gddu1dpb4
You might find this interesting. Since I couldn't get mine to power up at all, I called Samsung tech and they quoted me $75 to fix it and they would pay for shipping. I figured it was better then getting another phone off Swappa. 2-3 weeks later i get an email that they are repairing it under warranty at no cost to me. I got a refurbished phone since i know my IEMI number was different. they didn't explain why. Anyway, I got lucky i guess.
