[Q] Black screen, no boot, random vibration - Galaxy S 4 Q&A, Help & Troubleshooting

Ok, so my Galaxy S4 GT-I9505 won't boot up. Pretty common situation by what i have read on this and other forums so far but mine seems to behave a little different.
Since I've had the device it sometimes just randomly rebooted without any obvious reason but since it only occured once in a few month i did not investigate this any further.
Yesterday it suddenly got really slow when using some normal apps, nothing special (not like a little slow when the cpu is heavily used, but really really slow) it took about one minute for it to close any app and going back to the home screen etc, everything while still recording my actions so when it became unstuck just doing everything i tried in the meantime really fast, then again blocking. So far so good after a reboot that took 5 minutes (even the boot animation appeared extremely slow and fragmented) everything seemed normal.
Until it just freezed while i tried to make a phone call, during which it never dialed but just displaying the dialing animation, although i could switch back to the home screen and back to the "call" i could not end it or cancel it or anything, the phone behaved normal but the call stayed.
Then i tried rebooting it ...
... now it seems to be a brick, nothing will work it won't start up in any mode neither recovery, nor normal, nor download mode nothing.
After a few hours in the charger (i just left it there) suddenly the (untill then black) screen displayed the charging animation, when i tried to boot it then it just went back to a black screen.
After another hour it just started vibrating out of nowhere (and just stopped when i removed the battery).
Thats it, do you have any ideas on that ?
Some other info on the phone :
- rooted stock rom Android 4.4.2 from Vodafone
- tried adb, odin, but no connection to any pc possible at the moment

You have a faulty battery or some other damaged hardware.
Try to see if it boots with an other battery, if that fails then you have hardware damage.

Thanks for your quick reply! I'm going to try a different battery now ...

What ever happened with this? My wife's S4 started doing the exact same thing.

Oh, well I'm sorry I forgot to update the status here.
So I followed the instructions here and bought a new battery, unfortunately the problems didn't disappear.
As the S4 wasn't usable I sent it in to the repair service, which replaced the faulty electronic parts (the Mainboard as I guess). The defect was covered by the warranty in my case.
I don't know how I could help you here, in case the repair might not be covered by your warranty I would try replacing the battery.
Good luck

I think my Hermes is dead :(

Was working fine this morning, alarm went off etc and checked my mail. Put it into my pocket to read on the bus, got it out and it wouldn't come out of sleep mode. So tried reset with the stylus, no luck, so then pulled the battery and powered on.
All I get now is the green light coming on and staying on and that's it nothing else. I've got Hard-SPL the last released version and Shamanix Ultimate rom which has been fine for the last few months. And yer now this.
I've tried removing the sim card, the storage card and plugging it into windows. It detects something, brings up a network device but then I get nothing after that. I've tried using RUUWrapper to flash another OS rom but it still won't go. (This only happened once)
*Update* Somehow after plugging the usb cable in and holding power and the ok button to get the tri colour screen (even though its staying black) it managed to attempt to flash a new image to my phone. It said it was successful but its still not booting. I'm going to try and reflash the radio and hard spl but any other ideas? I tried looking for mtty to go through that way but no luck.
i had the same problem like you any help oli, pof or any one who could help to come back our hermes??
you sure its even a software problem? it seem to me like a hardware problem, like ur lcd screen is dead or something. i would try a remote control app like mymobiler and see if there's anything there first

Could be a hardware issue but I don't think its the LCD. The lights to indicate bluetooth aren't flashing which I had on by default. Its also not even flashing the green light at this point. It sorta powers on but thats it.
*Update*
After a bit of time the light did start flashing green but no bluetooth. The red and green phone buttons also turned on (Dopod 838 Pro). Its also now appearing to charge off the USB. But still no link in windows. I can ring the phone but nothing happens, it rings in the phone im using but the mobile itself does not.
well in my case my device if i plug it in the charger it charges but no led indication if i turn on the device only the green led turns on but it stays no start of splash etc etc etc only i can put it in bootmode if i flash it dont makes nothing
Well I dropped the phone into the service centre. It is 11 days (taking into account the leap year) outside of warranty. I'm kinda annoyed because the tech there said 3 would normally replace/repair under warranty at 10 days out of warranty.
Either way i've got a quote of $140, they claim its the screen but didnt have a screen in stock to test so i'm waiting for that. Three may still cover it under warranty because its so close to the warranty period and well i've had a few billing issues with them before where they were at fault. Namely the charged my credit card which they had been for over 6 months with no issues and then claimed I had not paid them. It took two weeks and multiple complaints before they accepted my bank statement showing them it was paid.
Still waiting now at almost a week and a half but hopefully its just the screen and they will fix it for me. They were hesitant to but I believe they will cover all of it, at first only offered 50% of the cost which is a bit of a kick in the teeth when its so close to warranty and under statutory warranty it should be covered.
Will keep this updated.
so has anyone figured out a reason/solution to this issue?
Unfortunately no
Once three got the parts in and tested them in my unit they were still unable to get it to boot nor get into some kind of special boot diagnostic mode they use so it was declared a complete board failure and deemed uneconomical to repair.
As it was so close to warranty they are now trying to sort out what they can do, possibly a loyalty upgrade or something similar. I've given them ideas of what phone I would like to get and hopefully they can accommodate me else I will look at chasing the statutory warranty angle.

HD2 Touch Screen Not Responding

Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!
Can anybody out there help with this? I am currently without a phone :-(
I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help
Check the flex cable.. this part are very delicate.
is this :

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.
same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds
Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!
I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.
This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...
Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.
I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/
just got off the phone with tmo. they are sending me a new one.
Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..
I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it
After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...
I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?
Mine sometimes worked well for hours... days... but eventually the problem came back.
Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.
I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...

[Q] HD2 won't turn on — short vibration and black screen

Hi everyone,
I would really appreciate it if you could give me an advice for my TMOUS HD2 P81120, that won't turn on.
I bought it with some firmware problems, spent plenty of time flashing it and finally managed to install a stock ROM from SDCARD using a fridge (it couldn't install w/o such cooling).
After that, it booted to white splashscreen with pink logo (smth like "Bringing happinness", don't remember the text) and stuck on it. I rebooted, flashed HSPL 2.08 successfully.
After that the device won't turn on at all. When I hold the Power button, all I get a barely sensible short vibration, but the screen stays completely black, no signs of life. I kept it on AC charger overnight — nothing has changed. When I hook it to the charger w/o the battery, and put the battery in, HD2 powers on itself (same short vibration, no other signs of life). Tried removing the sdcard, different combinations of power-ons, still nothing. Tried freezing it again for 5-10 mins — still no luck.
Please let me know what else I can try.
and one more thing — when I plug the USB, the PC doesn't detect any device.
It seems that a JTAG is my last resort, still I'm not sure I can find the hardware for that.

the problem is that your HD2 are overheating so the only thing thats left in your case is to replace motherboard

Good point!
Make sure that none of the three pins on the phone that touch the battery are bent. One of the causes of constant reboot is when one of those pins are not touching the battery. Please let me know if it worked for you...

That were definitely not the battery pins.
If anyone cares - here's how it ended (or not yet )
I found a JTAG service in my city, they wanted 50$ to restore the device to a working condition. I agreed, they took the phone. After that they've called me and said they have restored the bootloader, but can't make HD2 actually boot (they flashed stock ROM directly through JTAG, but it always got stuck on "Stick Together Screen". Now I understand I have probably flashed the wrong rom/radio — that's what has bricked it. I paid them 7$ for "diagnostics" and got back a phone with a working bootloader.
After that, I used the "fridge" method to flash latest radio for HD2 and some custom Win6.5.3 ROM (10 mins of fridge before each step). Then I cooled it again and put the cold phone on a frozen chicken (still laughing on that). Guess what — it booted into WM6.5, I even managed to make a call, though it rebooted in 3-5 mins. Overheating problems confirmed, at least it's not a complete brick.
What I've done now is found a guy that will try to "reball" the CPU's BGA - sort of "reheat" the chip to get a firm contact of it with the motherboard, and solve the heat problems. He'll call me today and let me know how it went — i'll update this topic.
As a conclusion, I can only say: "Check three times what you're flashing before you actually are flashing". Otherwise, JTAG is a wonderful "resurrection" solution, although a bit pricey (my case is pure luck).

Help identifying hardware problem

Hi,
I have my HTC HD2 for 3.5 years. I have replaced the touchscreen twice until now. Other than that, worked flawlessly.
Now i have a problem. The phone was dropped and landed on it's back pretty hard. When i picked it up, it was turned off.
After the drop, when i turn it on, it does random things, like:
1. the htc logo appears and gets stuck
2. the screen turns on white and nothing happens
3. the phone loads up the os fine, but the touchscreen doesn't work.
4. the phone loads up the os, touchscreen works, but everything is very very slow.
5. the phone loads up the os, touchscreen works, works normal, but after moving it around a little, everything freezes and nothing works anymore.
It goes through all these states randomly. it changes between them, if i shake it or tap it hard with my fingers.
after having it for such a long time, i know how to fix it my self. but this time, i can't identify the faulty component.
thank you!
probably motherboard or you can try if some button isn't pressed permanently.
try to clean/bend pattery pins
I tried what you said, no luck.
I was thinking that it might be the motherboard, i will investigate further.
Thank you.
Maybe the sd card slot is damaged, SD problems can cause a lot of weird issues!!
My 2 cents worth . ..

thank you for your comments. it looks like i'll never know what the problem was... i started selling the phone for parts. I already sold almost half of it. I bought a Samsung Galaxy Nexus.

Galaxy S7 Edge died

Hello XDA comunity
I need you help. Something strange has happened to my device. Today I noticed that my S7E was freezing with garbeled pixels on the screen and reebooting by itself. I tried to go to the recovery and do a factory reset and the thing is, the device froze in it too! So I actually managed to boot into it and backup everything. After that, I did a factory reset and everything seemed fine. So I went into recovery to test out if the phone would repeat the same freeze, and after I entered, the phone turned off and didnt turn on again. So now It wont even give out any sign of life, not even with the charger. I tried the power + volume down but it wont turn on. So now I am stuck with a dead device :/
Can someone help me?
Regards
---------------SOLVED--------------
Going to Leave this here in case someone gets it too.
If for some reason your SGS7E is freezing with artifacts on its screen and then reebooting, you have a corrupted firmware. If for some reason, it shuts off and dosent turn off, or it wont respond to the power + volume down combo, check if it feels warm to the touch (not warm like 40º ou 30º more like, warm for your surroundings) if it does, that means that somehow it got stuck and wont power off. Just wait for it to drain completly and try again.
Go to SAMSUNG STORE / SERVICES REPAIRS ; ))

Have you tried leave the phone on it's original charger
for at least an hour or more and then see if you can
get into either download mode or recovery?
I have seen many phones which have very similar
problems like your phone has and charging for at
least an hour on it's original battery charger will
usually allow booting into either recovery mode
and or into download mode.
If your phone can be booted into recovery or download
mode after charging and still has problems then simply
download the official samsung S7 Edge Nougat 7 or
Marshmallow 6.02 firmware and flash it with Odin3,
doing that will get your phone working properly just like
when you first purchased it.
Good luck,
Have a great day!

Hello, thanks for taking your time to help me. I'm on another account right now so dont be suprised about it since I forgot my password ahah.
Well, I'm testing the one hour charge and will reportback asap. The thing is, the device dosent turn on no matter what I do. I have a kill-a-watt so I can mesure its voltage and its showing 1.2 volts so I guess its doing something. I will report back asap.
UPDATE: Still not turning on :/

As one mentioned above: in that case: no boot, no Recovery, you have only one option, and the procedure is:
1. Pack your phone carefully, preventing it from further damage;
2. Using your laptop/tablet, PC, go online;
3. Open search engine, in search field place your town and "Samsung repair centre" then push enter
4. Remember the address and deliver your phone there. It may be handy to give them a call first
Sadly, this is only one option you have now.
Another Update
So after geting frustrated and wanting to trow the smartphone to a wall, to my surprise, I felt that the device was warm to the touch and decided to put it on its box while I went to sleep. I've just woken up and decided to try it, and it went stright up to the download mode. A few secounds later it turned itself off again, but I decided to insist and I managed to do it again while I connected it to the computer. I managed then to flash an original nougat firmware to it. After that I could finally turn the device on. So I'm just charging it right now so I can turn it on again and see if it can boot. I suspect that in some way, my firmware got corrupted.
TLDR: If your device feels a bit warm, just let it drain the rest of the battery and resist the urge to do the damn power reset and try again.

Dead Phone and no life at all
Im suffering the same damn problem with my 4 month old S7 edge.
Im in the UK but i bought the phone brand new boxed from Dubai, it is the international sm-g935f.
Box was sealed and brand new and bought from a major official retailer, i actually bought 2, one for me and one for wife, her one has been perfectly fine.
Long story short, last few months starting getting the screen freeze with blurred pixels, screen would stay frozen exactly as it was and then eventually phone would black screen and tried to reboot...
blue notification light would constantly stay on and it would NOT turn on and just loop with the s7 edge powered by Android logo unless i did vol+power down a few times, it would then turn on and proceeed to the flashing samsung logo before it would load up...
problem got worse by worse day by day,
i did everything from full wipe and factory restore etc safe mode etc, but it kept doing this and got worst over last few days...
now i could never get it start unless i actually tired the hard reboot power + vol down about 5 or 6 times and failing that i would try recovery mode then hard reboot again,
once turned on would be slow and laggy and glitchy at first then slowly get back up to speed and work again, only to die at some point or other when i would go to use it, unused it would stay on all day and recieve calls etc.
but last night i think i got the black screen of death... black screen with blue notification light soild blue and permanently on, no matter what i tried i could not shake the blue light, i got the s7 edge logo a few times before finally absolutely nothing,
light stayed on for about 5 to 6 hours i thought just to let the battery die.
this morning its all dead, no light no power no nothing. no matter what i try and any combination of keys i cant get it to even flinch, put charger cable on and nothing, no lights, no power or boot combination works
Have spoke to samsung here in UK, they say its under warranty but they wont touch it with a barge pole as Samsung EU Europe warranty only covers handsets bought in the UK or europe and this is a an international middle east handset according to serial and imei number and that for me to make a claim it needs to go back to retailer in Dubai and make claim with Samsung warranty there..
I was hoping it was just a software issue and thus have put up with it for so long as i have no way of sending it back to Dubai,
Does anyone know how i can just get it back up to life again, just to get my messages, some photos and media from it and possibly delete my google account on it as all whatsapp and insta and snapchat etc wud still be running on it if somehow i could get it to Dubai, as i had not password or pin protected it at all, its all open, so if someone did power it up, they wud have easy access to full contents
any help or any guidance would be so much appreciated, as im just sitting with a £450 brick at the moment and its very disheartening that usually an expert with samsungs just cant get this to work.
Im appalled at Samsungs attitude here in the UK, that the latest S7 edge flagship model is dying like this and many others round the world too, so its a common problem and they wont help at all, i mean u would think they would cover the warranty internationally as people travel all over world with thier phones and its the exact same handset they are selling at their official Samsung stores in the all the Dubai malls, in Duty free airport etc, its absolutely appalling, having been a samsung pro person from the first galaxy s phones, and owning and spending a large chunk of my money over last 10 years on samsung products in my household and family and friends and endorsing them wherever i go, its the first time i feel ever so let down by them.
hi guys.....
did anyone have a read of my post?
any help or ideas guys?
update....left it plugged in to see if it would charge....but still nothing, no warm up feel or doesn't even look like its taking any charge.
so how long should it leave it unplugged to see if maybe it needs completely draining?
still cant get it to power using any key combination at all

hi guys.....
did anyone have a read of my post?
any help or ideas guys?
update....left it plugged in to see if it would charge....but still nothing, no warm up feel or doesn't even look like its taking any charge.
so how long should it leave it unplugged to see if maybe it needs completely draining?
still cant get it to power using any key combination at all

I left mine over two hours off charge. Same simptoms. I guess it depends on the amount of charge left

Dead Phone and no life at all
Im suffering the same damn problem with my 4 month old S7 edge.
Im in the UK but i bought the phone brand new boxed from Dubai, it is the international sm-g935f.
Box was sealed and brand new and bought from a major official retailer, i actually bought 2, one for me and one for wife, her one has been perfectly fine.
Long story short, last few months starting getting the screen freeze with blurred pixels, screen would stay frozen exactly as it was and then eventually phone would black screen and tried to reboot...
blue notification light would constantly stay on and it would NOT turn on and just loop with the s7 edge powered by Android logo unless i did vol+power down a few times, it would then turn on and proceeed to the flashing samsung logo before it would load up...
problem got worse by worse day by day,
i did everything from full wipe and factory restore etc safe mode etc, but it kept doing this and got worst over last few days...
now i could never get it start unless i actually tired the hard reboot power + vol down about 5 or 6 times and failing that i would try recovery mode then hard reboot again,
once turned on would be slow and laggy and glitchy at first then slowly get back up to speed and work again, only to die at some point or other when i would go to use it, unused it would stay on all day and recieve calls etc.
but last night i think i got the black screen of death... black screen with blue notification light soild blue and permanently on, no matter what i tried i could not shake the blue light, i got the s7 edge logo a few times before finally absolutely nothing,
light stayed on for about 5 to 6 hours i thought just to let the battery die.
this morning its all dead, no light no power no nothing. no matter what i try and any combination of keys i cant get it to even flinch, put charger cable on and nothing, no lights, no power or boot combination works
Have spoke to samsung here in UK, they say its under warranty but they wont touch it with a barge pole as Samsung EU Europe warranty only covers handsets bought in the UK or europe and this is a an international middle east handset according to serial and imei number and that for me to make a claim it needs to go back to retailer in Dubai and make claim with Samsung warranty there..
I was hoping it was just a software issue and thus have put up with it for so long as i have no way of sending it back to Dubai,
Does anyone know how i can just get it back up to life again, just to get my messages, some photos and media from it and possibly delete my google account on it as all whatsapp and insta and snapchat etc wud still be running on it if somehow i could get it to Dubai, as i had not password or pin protected it at all, its all open, so if someone did power it up, they wud have easy access to full contents
any help or any guidance would be so much appreciated, as im just sitting with a £450 brick at the moment and its very disheartening that usually an expert with samsungs just cant get this to work.
Im appalled at Samsungs attitude here in the UK, that the latest S7 edge flagship model is dying like this and many others round the world too, so its a common problem and they wont help at all, i mean u would think they would cover the warranty internationally as people travel all over world with thier phones and its the exact same handset they are selling at their official Samsung stores in the all the Dubai malls, in Duty free airport etc, its absolutely appalling, having been a samsung pro person from the first galaxy s phones, and owning and spending a large chunk of my money over last 10 years on samsung products in my household and family and friends and endorsing them wherever i go, its the first time i feel ever so let down by them.

Hello friend
I know that feeling. I had the same feeling after I saw my phone going dead on me. Well, this will sound crazy but, for now just leave it on your desk over a night, dont try to charge it, dont try to reset it, just leave it for at least 12 hours. My phone died like that, it started to loop each time I got the artifacts on the screen. Worse, it even did the same on the recovery menu. I bought mine with dubai firmware. The only diferent thing I did, was to flash 7.0 BTU rom directly on it since I live in portugal and the phone had a ton of apps that were in arabic. I used odin to flash it and for a week or so, the device worked flawless, only missing some important apps from the system wich I found to be odd. Now, for the good news, after hours of research at the time I actually learned that samsung build in a switch in case of inconsistent booting or kernel panic errors, that make your phone simply turn off to avoid a battery explosion (Like the note 7). This means that the phone wont charge or turn on if this switch is on. So I felt that my phone was not hot, but just warm to the touch when everything arout it was at 2º celcius. That meant that it was stuck with the screen turned off. I just let it sit for 2 hours while I took a nap and after that, I actually didnt use the charger right away, I tried the download mode key combo and it turned on. But since it was without battery, it turned of instantly. So I tried again and after it went straight to download mode, I connected to the computer and flashed the 7.0 btu firmware again. After this ordeal, I actually learned that the first flash actually didnt install a ton of system apps or functions that in turn, made the cellphone freeze. You can flash an original firmware in your phone, it wont brake the warraty or touch the knox 0x0 warranty.
There is a high chance that when you update or flash the firmware, something can go wrong (in my case it was a corrupted firmware doing to the internet connection). This will be the same with OTA's I guess. So dont despair, just let it sit for a while and tri again after that. With no battery the device will turn the switch off and you can use it afterwards again. The faul its at the software.

I debranded from dubai firmware to android 7.0 UK BTU ROM. I redownloaded and flashed again when I got the chance to do it, and so far I have 0 problems with freezes or artifacts. Check if the firmware is properly downloaded before doing anything to avoid a stuck screen of death that may take a long time to discharge the battery.
For both of you guys, I'm sorry if my english sucks
If you guys need anything else, just PM me or respond here on this tread and I will try to help you as mucha s I can.

Any way i can get it to turn on or somehow power back up again?
Any manual or computer way?
Have tried charging it and then leaving it for few days and then tried powering back up, but still nothing.
Usually when it used to freeze and black screen trying the power and vol down a few times would re boot it...
But right now it just seems like its died for good...
Please help anyone?

Yes i would love to be able to flash it again or even wipe/factory data reset... Im very familiar on how to to that using stock roms or custom roms, but I can't even get it into download mode...
If I could just get it to power and into download or recovery mode then I would at least be able to do something with it.
But it seems your right like it is stuck on the black screen.
I left it in charge last night...
So now im. Thinking just to leave it without charging at all again...
But how long to wait till I know if it's properly battery dead and discharged?
If I do that then surely if battery is completely drained and discharged then it wont even have enough power to go into download or recovery mode?
Then do I attempt to try charge it again?
Risk is not knowing how or when of the battery is will be completely dead...
If it is stuck/frozen in black screen then charging it again will just prolong it again?
Uurrggghh its driving me crazy

In my opinion, you sould get a kill-a-watt to plug into a wall plug and to the charger to see the voltage thats going trough. If its 1,4v then the device is turned on but with a black screen (At least thats what it was showing to me, and its 1,4 because is just suppling energy, not charging).
The time it takes to discharge depens on why is stuck on that black screen. Mine was stuck at the recovery screen and took like 2 hours to discharge completly.
Unfortunally I'm having artifacts again :/ so this time I will downgrade my phone to 6.0.1. The simptoms I have when it does this, are overheating and extreme lag whithout doing nothing. Another suspicion I have is, it seems that the device does this when it wakes up.
I will take it directly to sammy next week anyway for them to analise it. Will report back asap. Meawhile I will test out other stuff too see what can be causing this.
Should I just talk to Samsung in Dubai?
And im thinking that possibly just send it back to them directly and let them deal with it under warranty?
I'm wondering if they will even let me do this?
I have the original receipt or both the phones from where it was bought in dubai.
The worst thing is the phone is only 4 months old when I bought it brand new and the one I bought for my wife is fine...
Her one is running a absolutely perfect and all latest updates etc, never ever crashed or ever frozen once, and she does a lot of photo and video editing on Instagram as a food blogger so her photo and video apps really push the phone.

Well, like someone said a few posts above, it seems that there are some units that have a sort of defect in the motherboard related to power states. I suspect that I have the same defect on my device. Samsung has a global warranty http://www.samsung.com/sec/support/guarantee/InternationalWarranty/ so I dont know if this could help you. I'm lucky in that department since the company that sold it to me aquired it from dubai but the reciept is from my country so I can solve this problem here.
As a last resort you should sent it to dubai since its worth the money IMHO

That global warranty is only for Laptops, trust me I know from previous experience and it was excellent how they replaced and fixed my laptop even when i was abroad and once they sent me out a new battery whilst I was abroad to my hotel address.
butthey do not do global or international warranty on mobile phones.
The phone has to go back to samsung repair centre in the country of origin of the phone and they can tell just from the serial number.
So UK/Europe handsets can be repaired under warranty in country in Europe at samsung repair centres but they wont touch non UK/EU handsets. My Dubai/Gulf S7 edge can go back to any repair centre in gulf states or country.
Its ridiculous really as the phone is exact same hardware and even same model number as uk/eu S7 edge SM-G935F with the only difference being the regional stock firmwares.
I just laughed at the UK repair centre customer sevices guy as tried to convince me that the phones were different because they carried different software..... And thats why they cant touch a dubai phone as it according to him setup differently, just couldnt be bothered to argue or explain to him that I could make a uk phone look exactly like a dubai phone with the flashing of the correct regional firmware.

If I could just get the damn phone to power up im any mode again im sure incould try and fix it again with the proper latest 7.0 nougat stock firmware...
But i am suspecting like many others and lots of samsung warranty repairs being done here UK/USA and abroad all over the world that some particular version of these handsets definite motherboard problem and all being replaced by samsung under warranty and problems fixed after motherboard replacement....
Arrggghhh
Teaches me right for going for the titanium silver model...
Lol i should have just got the same as my wife and bought 2 gold handsets.... She wanted the gold and i wanted to have a different one to hers and preferred the silver...
So now another headache....
How the hell do i send this back to Samsung in dubai and havr them return ot back to me without facing any customs and duty tax issues in dubai, and also if and when they send the phone back here in UK i think I will face customs and duty tax issues here again.
Anyone know any info about this?
