Samsung S7 Edge problems with PWM - Samsung Galaxy S7 Edge Questions and Answers

Hi all,
I have recently purchased a samsung s7 edge on contract and had nothing but problems with the phone, first of all after 15 days it stopped charging, was repaired but damaged by the repair centre who has smashed the screen and now refusing to fix the problem.
The phone itself has a problem with the PWM and is messing up the screen, its flickering all different colours and looks like a pipboy (fallout game) when left with the screen on mode.
I was wondering if the PWM on the phone is hardware based or software based, since im now left with a 2 month old phone which is completely unusable. I have factory reset the phone via the recovery menu, cleared the cache and wiped data but still has the problem.
I have read that people are suffering from this with the new marshmallow update, since i cannot actually so into any app i cannot see if the phone updated to that version, so im thinking if the issue is down to the marshmellow update the PWM would be controlled by the software and maybe if i go back a andriod version this would solve the issue.
Any one have any advice or information relating to this matter?

[Q] GS5 900F Clock/Time bug?

As per usual, I get the weirdest bugs/faults with my devices!
Just got a new S5 32GB from Singapore (900F variant). Was on holiday there, and they don't have that version in Australia where I live. Anyway, I tested the heck out of the thing while I was there, as the warranty is only valid in Singapore, and I wanted to tease out any hardware faults early.
When I was changing the SIM card once, I noticed that the system time had lagged a significant amount while the phone was off. In fact, if you turn it off and take out the battery for long enough, the time can change to several days in the past! To the best of my knowledge, modern phones, like PCs, keep accurate time even with the phone battery removed. I have confirmed this with my old S3, as well as other Samsung phones at the store.
After several visits to the local service center in Singapore, I finally convinced them to change the mainboard. After the repair, the problem was still present.
Has anyone else experienced this? Or can they test this? I keep the Auto time Update settings always off, and have done that for all my phones.
Changing of the main board would seem to exclude a hardware issue, but then there were some questions as to whether the main board was actually replaced by the repair center. The online tracking of the repair order ended in 'unable to be done due to request cancelled', which made me *really* suspicious, and the IMEI and serial numbers remained the same. Have never dealt with Samsung in Singapore before, so not sure how things work there. That's another story though, I suppose...
Update: Have gotten the phone back in my actual hands, and tinkered more with the problem. Have noticed that after a battery pull, the system time seems to default back to certain points in time (this time, 2118hrs, 18th July 2014).
Can anyone try a battery pull (leaving the battery out for a few minutes) with Auto Time Update off to see if this happens to their S5?
Thanks!

S7 Edge - Freezing and random rebooting

Hey all,
I have a galaxy s7 edge that's 2 months old. It's randomly freezing which is forcing me to do a hard reset or rebooting. I have done a factory restart by the settings, I have done a factory restart by holding the power, home and volume up key and lastly I have done a smart switch emergency thingy-me-bob.
The phone has never been rooted or messed around with in that matter and was working flawlessly up until this point. It's running all the latest updates you can get OTA - My next step tomorrow is to go into store for them to essentially repeat what I have done for several months...wondering if anyone here has any ideas of anything else I could try? Hoping it isn't a hardware defect.
Cheers,
Tom
Had exactly the same issue. Ran it in safe mode and it still froze. Factory reset - still the same problem. Sent it off to Samsung and got it back a few days ago along with the usual note explaining that the fault had been identified, latest software had been installed and it had passed through quality control. Went through setup and within an hour it was freezing again. Not convinced Samsung did anything other than re-flash the firmware and send it back. I'm guessing that this is a hardware issue, as I have read many posts with people experiencing the same issue. It's going back tomorrow so they can try again, with a note in the box, politely asking them to dig a little deeper....
Did another factory reset and it's frozen while on the always on display svtren. Think I'll be leaving a note asking them to do a physical hardware check!
You have latest software?
As per the original post, everything is running on latest.
Any way, visited the 'Geek squad' who informed me that I had done a factory reset wrong *sigh* restarted it infront of me and would you believe it! crashed. They're now sending it to Samsung to look at who I assume will just flash it again.
Very very disappointed with the edge, compared to my OP3T it's so sluggish.
had the same problem. had to send mine to samsung. there was something wrong with the partitioning i think but in some way odin couldn't fix
Fingers crossed it's something like that is wrong with mine!
I have exactly the same problem.
I'm in aus, and bought the phone from HK, so I'm a bit reluctant to send it back to HK/China.
I've done everything... but still the same.

From what I have read, it sounds like a hardware issue. The guy are the store was an utter moron but he did say the harder it is to the fix the more likely they are to just give me a new phone. Once i get it back ill share what they've done and see if it can help fix your issue.
Mine does reboot from time to time. Once a day, once a week...
Sometimes reboots when it stands alone on charging, sometimes in my pocket. I just realizes when my smartwatch vibrates to advert lost bluetooth conection.
Lastest firmware. I´ll probably will send to warranty.
I just recently got the S7 Edge. Great phone I just hates when it does that.

Screen frozen but touchscreen still working

A couple of days ago I started having issues with the responsiveness of my screen and it seemed to get worse over time. I soon found out that the screen didn't seem to refresh, as the touchscreen was still working and the phone itself still did what it had to do, only the screen itself did not refresh. My phone is rooted, however a couple of weeks ago after my screen, while watching videos started dancing around, I decided to return it to stock to see if the issues continued (they did and became worse). When I went through the setup of the stock software I could press next, however the screen would not change to the next screen, however, when I turned off and on the phone, it would be on the next screen.
I am wondering if anybody has an idea what the issue could be with my phone? First I was convinced it was a problem with the rom, as the phone worked fine and the screen doesn't have any issues besides the refreshing issue. However the dancing screen while watching videos reminded me of graphic card issues. Samsung obviously doesn't cover the repair as the warranty has voided, so my consideration now is the fix my phone or buy a one plus 3t.
Thanks for your help!:fingers-crossed:
Btw: it is the SM-928F United Kingdom 02. I was running the Pixel nougat rom (couldn't stand the ridiculously long wait for nougat). I changed back to stock with the Kies software of Samsung. I have posted a video to explain the issue better: https://youtu.be/vKmVi0lo7VE
Thanks!

S7 Edge SM-G935FD always Auto Restarting[urgent help needed]

Maybe your power button is jammed?
When i checked, Power button is pressing and releasing. Power button is functioning actually, I can enter to Recovery, Download Mod and I can lock screen using power button. Or any other method to verified power button?

My S7 Edge did the same thing I reset it to factory settings empyrion I went in and did safe mode I tried resetting it and not installing any applications it seems that my ROM had gotten corrupted or something for no reason there was definitely a hardware problem. Never could figure out what it was I had insurance with Verizon and because I had cracked the screen barely three months prior before the problem began they stuck me with the $200 deductible to get it replaced. if you got insurance you will probably have to send it in but what mine was doing was it started just lagging then it just got to wear it wouldn't do anything it would freeze up and just reset and it would continually do that even when no programs installed except the factory setting and it would reset until the battery died I don't know that's exactly what you're experiencing but mine was in a constant Loop of reset it didn't get water damaged or anything the only thing I can figure is it had the 7.0 nougat update when it began doing this hope that helps you out sorry for the run on I'm talk texting I'm with the S8 now I haven't had any problems I'm just wondering if they've actually supported that I hadn't heard any other people having the same problems but mine surely did right after I got the update Android 7.0 on Verizon good luck bud

YES!!!..........Its exactly what you described. It started in the beginning like get slow>freeze with in 1 min>restart......But now after installing stock ROM back, its now directly restarting like a loop....Only difference we could use/see mobile for 10-20sec.....with in that time, it will restart again.
Unfortunately I dont have insurance.
If its hardware problem, samsung will rectify with accepting payment??
My S7 Edge did the same thing recently....no fix but to send for replacement. I reset it to factory settings. I went in and did safe mode. I tried resetting it and not installing any google apps. Seems that my ROM had gotten corrupted or something for no reason there was definitely a hardware problem or corrupted data in the OS or ROM. Never could figure out what it was. I had insurance with Asurion and Verizon but because I had barely cracked the outer screen 3 months prior (digitizer and oled where fine....was just outter guarilla glass which people complain about due to having no tempered glass to fit it correctly. So i had gotten the skin type scratch protector and one 2 foot drop onto asphault not even 2 weeks after receiving the object...pebble cracked it on the edge. Three months the problem began with freezing amd resetting finally b4 giving up and making a claim. ASURION stuck me with the $200 deductible to get it replaced because they said the drop/crack caused the malfunction though it worked perfectly for the 3 months...even had full sensitivity at the cracked area. If you got insurance, i imagine you will have to replace it. I did ad i saw no other choice and it ticked me off them sticking me with the deductible of full 200. Leave the cracked screen on hell. Just fix what they didnt fix when they got it to refurbish it initially. Have gotten at least 5 poorly refurbed phones that didnt last a year that was passed off as GOOD AD NEW. Mine started lagging then it just got to were it wouldn't do anything but cycle reboots. It would freeze up and just reset and it would continually do that even with no google or verizon account setup or apps. Only installed the factory settings which included the preinstalled bloatware. Phone would boot, then reset, boot and would reset again...continuous loop until the battery would die.
I don't know if that's exactly what you're experiencing but mine was in a constant Loop of reset. T here was no water damaged or anything other than a drop months earlier, an update, and i had recently moved some apps to the ext Sd card (which that should have been resolved at factory reset) cause i removed the micro sd card incase it was conflicting in someway from priorly having apps installed onto it.. the only thing I can figure is it had the 7.0 nougat update when it began doing this. Hope that helps you out. Sorry for the run-on sentences. I tried clearing up my grammar and punctuation...at least look a bit edumacated.? I had been talk texting.
Currently, I'm with the S8 now. I haven't had any problems so far. Dont like the default samsung voice input that it resets to constantly. But i am sure the S8 has more support for the new OS THAN DID s7. Phone companies are notorious to slack on support for models even 1 year old. Minimal support at best. You might get 2 Android OS updates. Not likely though. Pushing the new big thing each year and forget about the loyal customers that have chosen to spend out money with said co. rather than their rival. After the N7 hand grenades. Time that Samsung start supporting their phones updates a bit better. I'm really of the opinion that sufficient testing and support wasnt given towards the s7 the 7.0 OS. New OS updates Always buggie when first released. I hadn't heard any other people having the same problems as we did but i havent looked. Verizon claims no issues from the update. I question all retailers truthfulness on such issues. It a business and i see hoe much they mark up their retail products. 5 time the cost of internet prices many times.
Do report back pleas e. Sorry so winded....wanted to give all my thoughts and details of my exact experience. Hope you can fix it cheaper than i did. The s8 is sure to have more samsung support for a longer time. Nag them if you are settling with insurance. They can give you a new phone vs. Refurbed if they want to make u satisfied.
Good luck brother. Many blessings.

Display gone dead

I've only had this phone for about a month and been running Havoc, I just upgraded the rom about 4 days ago. The screen just went blank out of nowhere yesterday, the phone is always on. Even when I boot into recovery or flashboot, still no display. The screen gets lighter when it powers up and you can access the storage, just no display. Obviously, I have no warranty. I'd just like to ask if this is a definite hardware problem or is there any possibility of it being a software issue (don't think so but could be wrong).
Much thanks in advance.

Try flashing stock rom from aft or fastboot if still the display doesn't work then it's a hardware issue
it might be a hardware issue.
Since nobody else seems to be having this specific issue, I've got to assume it is a hardware problem. Not overly thrilled with Asus at this point, I had one of their tablets randomly crap out on me not too long ago. Anyway, we'll see how far I get with customer service after "voiding the warranty", I've started an RMA with Asus and Banggood is requesting a video demonstrating the issue. I'll just follow up here if anybody is wondering how that process goes.
