[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
I had a right nightmare at the Samsung support store I went to today, the only thing they'd do first off was to flash the firmware again even though I told them I'd re-flashed it numerous times and that them doing it again wouldn't do diddly squat but apparently how they flash it is different to how we do it, I should of asked them if they put the phone into download mode and flash the phone with odin!

Anyway I had to return after an hour to pick up the phone and as I'd left my sim card at home thinking they were going to keep the phone and repair and not just flash the firmware i had no way of testing the phone as I had no free WiFi to connect to and one thing that tended to freeze my phone was multitasking while installing lots of apps.

So I got back home and started installing all my apps from Google play while browsing and generally doing lots of stuff while all the apps were being installed in the background and what do you know, it froze and instead of rebooting after a while it stayed frozen with the screen on so I jump back in my car and drive back to the support store so I could show them the phone had locked up as proof and the damn battery must have ran out literally 2 minutes from the store as the screen was blank and I couldn't power it back on. All this was worse by the fact it's just under a 40 mile round trip to the Samsung store which I've made twice today.

They took my word for it anyway, I just hope it's fixed when I go to pick it up next week.
[Samsung Galaxy S7 Edge Questions and Answers] lossah:
I wonder, what firmware are you guys using with those kind of problems?
[Samsung Galaxy S7 Edge Questions and Answers] Will_i_ams:
Completely stock and whatever was the very latest one. All apps up to date too.
[Samsung Galaxy S7 Edge Questions and Answers] pshdo:
UPDATE!

The service center told me that the complete motherboard in my phone was changed. (Amazing that this can be the best solution, prize wise)

- so people, if you have this freezing problem, then send the phone for repair, sooner beter than later!

From the papers i recived with my phone, the board changed is: assy-pba main(comm) G935F/M32
[Samsung Galaxy S7 Edge Questions and Answers] Wildestdrm:
My phone fresed while I clicked powerbutton while playing a game.
[Samsung Galaxy S7 Edge Questions and Answers] Will_i_ams:
That's really interesting. Great that they changed the board for you! I wonder if mine has the same problem/repair...
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
Just had to phone Samsung as they decided to finally email me about my phone being picked up on Wednesday! Little but late though as I decided to take it into their support store 20 miles away after having no reply back from my email last week so while on the phone I asked if she could check on the status of the repair and she said the pba has been replaced so it would seem the same board has been replaced in my handset.
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
Picked up my s7 edge this afternoon, very impressed with the speed of the repair, taken in on Friday and all done by Monday! So far so good, fingers crossed the replacement main board has cured all the issues I was having. One thing I'm not sure about is the state of the battery, it died while I was taking the phone back on Friday to show them the frozen screen and the battery was complete flat when I plugged it in to charge it and I'm not sure what damage might have been done with the battery being left completely discharged like that but hopefully it won't impact on battery life.

One other thing I've noticed, before the repair my phone wouldn't wireless charge unless I took the phone out of the spigen case I use, now it charges with the case on so I wonder if something else was faulty with the original pba board.
[Samsung Galaxy S7 Edge Questions and Answers] RiTCHiE007:
Anyone ever had this fixed? I have the same problem and i have tried it all.

---------- Post added at 06:38 PM ---------- Previous post was at 06:27 PM ----------

Im in the same boat bro! Freezes and black screen lockups and when im in safe mode it seems gone so it should be a software related thing but im scared to send my phone back for repairs because samsung hires a 3rd party company for these problems and dynafix have a horrible reputation.
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
If numerous apps are freezing your phone then imo it's a hardware issue with the main board and not a software problem, I now have zero issues with my S7 Edge since having the pba board replaced, opted not to send my phone off and instead took it to a Samsung support store 20 miles away to get it fixed.

I don't know exactly what the fault is with the main board but clearly certain apps appear to cause the faulty board to lock up and freeze the phone. I could play numerous games and had no issues, then I'd open up tapatalk or Skype or other apps and there was a good chance the phone would freeze up completely.
[Samsung Galaxy S7 Edge Questions and Answers] RiTCHiE007:
Hi, well all the apps seems to work fine and none of them are freezing but it seems that after using some apps and then when i turn off my screen that after a while it seems to lock up and wont turn on any more. I have tried to delete my apps, flash new firmware, new sd card etc but no go but now that im in safe mode it seems oke. Did yours free in safe mode?
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
Yeah it froze in safe mode, have you tested your handset by using it without an sd card for a while to see if that stops the freezing, if not then that's worth a try.
[Samsung Galaxy S7 Edge Questions and Answers] Will_i_ams:
So this is what they've done to fix mine...

(SPOILERS....) Nothing. They've done nothing.

No crashes so far, I report if they do
[Samsung Galaxy S7 Edge Questions and Answers] Will_i_ams:
Don't understand the weird double post.
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
Looks they just re-flashed the firmware like they did for me on my first visit to their support centre, they also told me it appeared to be working fine, didn't take me long to get the phone to freeze though via heavy multitasking while Google play was re-installing all my apps and by using apps which had a tendency to cause the phone to freeze up.

But who knows, maybe your issues weren't caused by a faulty pba board.
[Samsung Galaxy S7 Edge Questions and Answers] Will_i_ams:
Yeah I don't want to seem ungrateful. They've tried to fix it for free and to be honest, if it was my company, I'd try the cheapest thing first too.

I hope what they've done is enough but I'm definitely not optimistic.
[Samsung Galaxy S7 Edge Questions and Answers] 5icz:
I am still debugging my Dual Sim S7. I though one of the SIMs I use might be causing this issue or one of the Sim slots but unfortunately the phone freezes either with only 1 SIM in the phone ( I tried both Sims alone) and also the freeze happens when the single Sim is inserted either in Slot 1 or Slot 2.

Simple system monitor app shows a high CPU usage during idle by system_server process (about 15% load). Can other people check if they see this process also highly active?
[Samsung Galaxy S7 Edge Questions and Answers] olafd72:
I had the same thing. I purchased and the next day, it rebooted. OK, can happen. Then a few days later again, I saw my phone on the chair next to me in the car, rebooting. Then I encountered later, several freezes. I had to reset it with volume-powerbutton. Then an OTA update was installed a few weeks ago and then it started rebooting every second. I brought it to the Vodafone store, they sent it to their repair center (or Samsung's ?) and I got it back with in a week. They replaced the board and it said 'software update' (although I already had installed the last updates?). When I picked it up at the store, they said it happens a lot with the S7 Edge. Luckily it is now all solved.

By the way; prior to repair, it also thought battery life was really poor. Now it is fine!
[Samsung Galaxy S7 Edge Questions and Answers] alex6600:
I have one reboot after 1 month of use. Without freezes. Phone been in standby on desk.
[Samsung Galaxy S7 Edge Questions and Answers] oaz63:
so the only solution is to send the phone back to Samsung? i really don't want to go through the hassle and trouble with them!!

it'll take weeks to get the phone back :(
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
If your getting random freezing and rebooting, especially if it happens in safe mode or with apps that come pre-installed with the firmware then yes that is the only solution as your phone has a faulty main board (pba board as they call it) and your gonna want to get it sorted while it's under warranty.

I was lucky enough to have a Samsung support centre 20 mile drive away so I took it there and had a very speedy repair and the phone has been running like a dream since, not one problem since the pba board was changed.
[Samsung Galaxy S7 Edge Questions and Answers] alexisgt:
What about the waterproof protection after the device will be opened for a main board replacement?

Is there any chance the factory sealing won't be anymore as much effective as it should?
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
Can't answer this with a definite answer but if the phone is repaired by Samsung i would of thought it should still be water resistant, I expect they put the phone together exactly the same way as it's put together when originally manufactured.

The way I see it, Samsung advertise the s7 as being water resistant, I see nothing mentioned anywhere about that only being the case as long as the phone hasn't had a repair done to it.
[Samsung Galaxy S7 Edge Questions and Answers] 5icz:
I flashed Android 7 beta and still the freezes and restarts happen. I am now going to send it for warranty repair since I believe it is HW problem.
[Samsung Galaxy S7 Edge Questions and Answers] Will_i_ams:
Test
[Samsung Galaxy S7 Edge Questions and Answers] thewelt1:
Yep happened to me loads thought it was software related..flashed nougat beta 2 weeks ago everything fine til yesterday phone constantly rebooting didn't even respond to touch after resetting turning into complete nightmare..my mrs has s7 edge adwell and she had no issues. Think ive just got a dud..??
[Samsung Galaxy S7 Edge Questions and Answers] Crucio_:
Don't know if its a good or bad thing that others are having the problem I'm having. Guess its nice to see its not just my device, but that is just worrying.

I purchased mine off ebay two weeks ago, an unwanted upgrade and now i cant use the phone more a long period of time without it freezing or rebooting, even have had the device freeze during the Secure Setup. The device is in safe mode right now and i'm not having the issue for now. How are people testing to see what app may be causing the issue? surely like me people install many apps at once, do i really have to go one app at a time, use it for a period of time, see if the freeze/reboot happens? or is there a log dump that we can see somewhere?
[Samsung Galaxy S7 Edge Questions and Answers] hobibur:
I have had this phone for just over two weeks. The freeze/black screen happened 2 in the 2 weeks around 5 days apart.

But since yesterday, it has happened about 6 more times. Only way to get the phone alive again is holding the power and vol down buttons.

What is the warranty policy with Samsung, can I just take it to one of their service centre and have them look at it. The phone is 2nd hand Grade A. Will that effect the warranty?

The phone is a UK O2 Network (unlocked now) Exynos.
[Samsung Galaxy S7 Edge Questions and Answers] Smartie36:
While running in safe mode have you tried going through all the apps that come pre-installed with the firmware, open an app, play about with it for a while then move onto the next app and just keep doing that for an hour or so and if it freezes or reboots then I'd say you have a faulty pba main board which is what the fault was on my phone.

Mine took longer to freeze while running in safe mode, I spent a while just alternating between all the pre-installed apps and eventually the phone locked up on an app that previously had worked fine while I was flicking through all the apps.
[Samsung Galaxy S7 Edge Questions and Answers] 5icz:
Finally my phone phone returned from service and seems that the freezes are fixed. So for me I could not find any SW or SIM or SD card problem which could be easily fixed and the board had to be replaced.

[Samsung Galaxy S7 Edge Questions and Answers] Tarar:
Hey Guys.

I am having these freezes/restarts randomly.

i cannot return the phone as i bought it from OLX.

is any fix available yet?

also i am encountering this "failed to mount data/invalid argument" error on recovery.

does this have anything to do with the freezes/restarts?

Please Help.
[Samsung Galaxy S7 Edge Questions and Answers] DarkSandmaN:
I am thinking to buy S7 edge but reading this i am not so shure now :( are lot s7 edges affected buy this freezing and restarting or just some of them? i see this thread have only 10 pages so i am little optimistic :)

Does it do that on snapdragon or exynos devices?

Is it maybe sd card problem?
[Samsung Galaxy S7 Edge Questions and Answers] MonstaSaleens:
I'm sure it's only some. Mines, plus a lot of the guys in a telegram group I'm with have no problems with their s7's get it new and it should run perfectly. Just got mine 2 weeks ago and have gear vr and all type of accessories for it. Everything is fine for me.
[Samsung Galaxy S7 Edge Questions and Answers] Tarar:
Did root and custom firmware solve the problem?

Please help.
[Samsung Galaxy S7 Edge Questions and Answers] Brava27:
Of course.
[Samsung Galaxy S7 Edge Questions and Answers] Shadeftw:
Atention!

Due to having several problems on my GS7E related to the ones you guys have I decided to post some pictures of my problem with the following explanations.

I originaly wrote this post here on xda https://xdaforums.com/s7-edge/help/galaxy-s7-edge-died-t3548658/post70956396#post70956396

After some tests and duds, I realized that I needed to bite the bullet and sent it in to sammmy since it was on warranty period. They changed the logic board and I got it repaired.

If your device freezes from nothing after you flash it, if it gets blank screen with or without led and heats up on one side then my friends... its time to take it to a repair center.

In my case, this happened:

Artifacts on recovery

Artifacts on instalation

So beware... DONT root it, DONT try other stuff that could make you lose your warranty JUST GO TO A REPAIR CENTER AND GET IT FIXED! Be totally honest with sammy techs, provide as many information that you can, record videos, take photos and prove what kind of failure you guys have on your devices.

It seems that there is at least 1% of the devices are with somekind of MB failures so my friends you should go, even with minor scratches (not shatered glass!) to sammy and get it fixed!!!

I'm sharing this to help you guys, so that you can fix this wonderfull device.

[Samsung Galaxy S7 Edge Questions and Answers] Tarar:
Yes it did solve it.

I noticed i was having an error "failed to mount data invalid arguement in the 6.0 recovery"

Now i am using twrp and haven't experienced a freeze/reboot yet.

Phone does overheat though.
[Samsung Galaxy S7 Edge Questions and Answers] Brava27:
Haha this post was a year and a half ago.
[Samsung Galaxy S7 Edge Questions and Answers] crmadera:
I currently got mine for 200 bucks. I did notice since day 1 that my phone would slow down and eventually freeze. I even noticed that it would randomly restart while charging. I really want to root it but I know I would void my warranty. Anyhow, previous to this phone I had an s4 (still have it actually) rooted. I used an app called App Cache Cleaner, which let me know how much there was at the time. I used the widget. I also used grenify to shut down apps I did not like. Those apps work amazing on a rooted phone. I started using those more on this phone and did notice that it helped, although the Cache cleaner app widget kinda sucks. What I also did is I added the S7 widget feature where you can see how much RAM you have available. I clear that often, usually before I turn off my screen. 4 days doing this and have not noticed slowing down or freezing.

I know I kinda made it confusing but as a recap:

1. Use greenify to pretty much shut down apps that you do not use/need (if you have a rooted phone this is a plus)

2. An app cache cleaner app would really help. Mine has a widget and is also set to clean it every 6 minutes (you can change the frequency at which it cleans)

3. S7 has a widget in which you can monitor the sotrage and memory and optimize it. Use it.

All this combined should reduce the amount of memory your phone uses. Unfortunately, we cannot take full advantage of this supposed "beast phone" because of all this freezing.

I hope this could help some of you. I'm not an expert on technology but this sure helps me.
[Samsung Galaxy S7 Edge Questions and Answers] obelix123:
so mine problem is little diff . my phone keeps freezing and then restarting by itself every minute or so . I tried TWRP to erase everything , tried flashing thru ODIN 6,1 n 7,0 android , tried also ticking in ODin - nand erase n repartition . but still keeps restarting , its not under warranty anymore :(

can anyone help ????
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
I cannot say what is exact reason of freezing/ rebooting, but I suspect an app or software or built in service causing this. Strangely and luckily though, in my 8 months of use i had yet to experience a single reboot or freeze, only an app froze one time and i pressed home button , at first it didnt respond but pressing another time it went to homescreen and I closed app through recent window and then uninstalled it, that app was dream league soccer game. Actually i am a heavy user and play games all the time. So i can say that the most likely chance fir freezing/reboots is an 3rd party app or may be a built in service, and the most less likely is hardware fault, especially memory controller etc. I would suggest going in safe mode to check if freezing/rebooting happens there also. Good Luck

Edit : A guy said above about nand erase, please understand NEVER EVER TRY TO NAND ERASE, you will simply kill your phone !!
[Samsung Galaxy S7 Edge Questions and Answers] obelix123:
guess what , I did not kill the phone with nand erase and repartition :) but problem of freezing n rebooting still exist , I think the problem will be in Motherboard , cause the same symptoms r when I am also in recovery mode
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Yes it may be MB, but again never do nand erase, if you didnt kill that means your nand isn't erased simply. I have researched thoroughly on this. You can see this post of mine https://xdaforums.com/galaxy-s3/hel...n-3-07-gs3-t1747066/post73733262#post73733262

Hello

I have Pure Nexus rom installed. I updated the Pure Nexus zip just fine. When I tried to flash the vendor .img file form TWRP ,I chose "Install", "Install Image" and then chose MMB29V_vendor.img and it then prompted me to choose which partition to flash image, Boot or recovery. I'm not sure what to choose and why. Any help would be appreciated.

Thanks

You are on an old version of twrp. You need to update twrp to version 3.00. When you do that you will have the option to install the vendor.IMG to the vendor partition.
[Nexus 6P Q&A, Help & Troubleshooting] chickenbristle:
Thanks so much, I'll try that!
[Nexus 6P Q&A, Help & Troubleshooting] dontbeweakvato:
Wait, stop! Before flashing twrp you should create a pin 4 digit when rom is booted (settings>security). Because twrp will encrypt Upon first boot with "default_password" except you cant use that as a password or decrypt with it. So create 4 digit pin when phones booted in your rom, then use flashify to flash new twrp 3.0.0.0 or .1 (its easy), then boot into recov while useing pin to decrypt data. When you next boot into your rom you can change security to swipe or nothing. So next time you boot twrp you wont get a "can not decrypt data" message. Even when there is no encryption pass word set.

This is from experience.

Twrp latest build has changed a little how it works.

Hey all,

Just some details before the background.

I was running a stock with a unlocked bootloader for a while now. I basically only use my nexus now to watch netflixs and HBOgo. Got the tablet over four years ago.

This morning after it's nightly charge I went to unlock it and it froze up. I rebooted it, noticed the date was off (Jan 1st) and froze after I unlocked it. Reboot again, it made it to the screen where it was optimizing my apps but the screen starting flickering and having artifacts, and powered off. Now it will power itself off 5 or so seconds into the boot animation.

I've tried going into recovery via the bootloader but when I select it and hit the power button it just turns it self off. I then used the nexus toolbox to reflash a stock rom (along with a factory reset), and TWRP. I tried booting up again and same thing. I then went into TWRP and start troubleshooting, but the screen is starting to flicker and have artifacts, then powers off.

Is the hardware dead on this?

Sorry for the jumbled mess of details, i've been bouncing around trying to troubleshoot/fix this.
