Wake-up gesture and heart-rate monitor stopped two months from purchase

Hey guys! I find myself in a bit of a pickle here. I got my Galaxy Watch (SM-800) two months back. Everything was working perfectly, untill a week back when my heart rate monitor and lift-to-wake stopped working without any warning. I've checked all settings (permission for gestures, wake-up gesture is also on) but I just cannot get these to work any more. I also flashed the latest firmware using NetOdin3, I was extremely hopeful that'll end my troubles but it didn't. I am planning to drop the watch off at a service center this weekend, but I've been a solve-things-by-myself guy for over a decade with my phones, and I hate having to visit the customer care. Is there any work around you guys can think of that I should try?
Thanks!

Severe brightness issue (screen largely unusable)

Hi all, I have a problem with my stock T-Mobile US S9. A few months ago this weird thing happened where if I turned on my screen immediately after it turned itself off, only the top few lines would be visible. The whole screen would take input, but you could only see a little below the status bar, maybe. If I waited a bit and then turned the screen on, it would work normally, with the whole screen visible and looking fine.
It's gotten progressively worse to the point where this happens most of the time I turn the screen on. However, I've found two workarounds:
1) My Always On Display is set to turn on when I tap the phone. If I do that, the AOD works as normal, and if I then turn on the phone screen the phone screen works fine. This only works when Always on display is set to turn on on tap. It does not work if AOD is set to always be on.
2) If, when my screen is glitching out I hold the screen up to a reeaally bright light (like inches from a lightbulb), the rest of the screen turns on. It's weirdly green tinted and kind of stuttery.
Turning off automatic brightness does not fix this issue. If tried booting in safe mode and even factory resetting the phone. Issue still persists, including on screens like when the phone enters recovery mode.
The fact that I can get the screen working normally using workaround #1 makes me think this is a software issue, but the fact that it happens on the recovery screen makes me think it's pretty low-level. Any ideas? Anyone else had a similar issue?

I gave Samsung tech support a call and the level 1 tech I spoke with seemed to think that it was a software issue and that I should bring it in to be looked at by a technician. I'm in Maine at the moment and there's no Samsung or UBreakIFix stores within two hours, so she suggested taking it to Best Buy to look at. Not amazingly helpful or surprising.
If it's a software issue though... I mean this is my fourth Android phone and I've rooted and flashed ROMs on all the previous phones anyway. I don't want to lose Samsung Pay, so I'd rather not unlock the bootloader, but is there a way to flash the stock operating system or something? The exact model number is SM-G960U

It's a firmware or hardware issue not software as a reload* would have fixed it.
The firmware has been corrupted (needs reflashed) or there's been a hardware failure.
Best to send it in for repair or take it the a Samsung Experience Center as they can reflash the stock rom and have advanced diagnostic tools.
*make sure all system apks are running on factory load and have not been updated after the reload.
Updates, destroyers of worlds...

If that’s really necessary I’ll do it. But the closest place is out of state and when I called them said it would take 4 hours just to do a diagnostic. That plus the round trip... if there’s a way I can save some time, I’d like to.
For example, if one possibility is a stock firmware reflash, that’s something I’ve never done before on a Samsung device, but not very different from things I feel comfortable doing. I've flashed roms and rooted many android devices in the past. From a preliminary search , it looks like there's even a leaked tool online to do so from Samsung called Odin and that I just need to find the latest SM-G960U image with the right "csc" code for my carrier (I think TMB for T Mobile US). What would be even better is if one of those diagnostic tools you mentioned leaked the same way that Odin did.
Any recommendations on either diagnostic software or firmware reflashing? Or would you strongly advise leaving that kind of thing alone? I would like to still use things like Samsung Pay at the end of all this.

If it's under warranty let Samsung deal with it. A good tech with experience is invaluable.
Rather then waste time the extra ride might end up being the easiest solution. You could also next or 2nd day it to the center and back, make sure it's insured and packaged well.

That makes complete sense for something under warranty, but unfortunately my phone isn't. The S9 is about three years old now, and the Samsung rep was quick to tell me that the device was no longer covered. It looks like a mail-in repair service would cost about $175, which I'm theoretically willing to pay, but not if I can just handle on my own for free.

In that case you have nothing to lose by reflashing it. Hopefully that gets it.
Otherwise it be hardware... probably a good chance this actually the cause.
The good news is the 9's are available for a couple hundred in good condition if need be.
I was considering getting the 9 as a second phone (have the 10+) as the 10+'s haven't come down much in price.
Samsung current lineup sucks.

Huh. Well, before reflashing, I tried something I found other people suggesting for a related problem: https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/7
It's an app called OLED Saver. It's not perfect, the screen still has an odd green tint to it unless I use one of the tricks I was describing above. But I no longer have the issue where most of the screen isn't visible.
I might try reflashing anyway, will post results if I do.

Yeah, no joy. Reflashed by downloading the latest firmware using Frija for SM-G960U with TMB as the CSC, and flashed using Odin v3.13.3. If anything the problem is slightly worse now, but OLED Saver still mostly seems to fix it. I guess it's just a hardware issue with a weird software workaround...

Same type of brightness problem here as you describe, on my new S9 (G960U) - - Model starqltesq - CSS XAA
The product is under guarantee, but as it is imported from Hongkong to France, I don't have accesss to the Samsung local representatives and have probably to send it back to Hongkong ...
I will keep you updated if I learn something about the problem and the solution ....

Wiping the cache partition stopped this happening for me for around 24 hours but it came back this morning. On the Note9 forums someone posted that setting animations to .5 in dev options fixes this. I will try it.

Disable animations instead. It wastes resources. Personally I like seeing a fast, snappy OS do it's thing with no middle man needed. Lol, you end up waiting for the animations rather than the OS.

I've heard of people flashing custom roms and that resolved the issue permenetly, but can't find anyone willing to give some real feedback. I posted a topic asking this question, but haven't gotten any replies..

Not very helpful, but a work around could be to use Screen Filter

I temporary fixing my S9+ green screen issue by uninstalling the NFC module.
Unfortunately, this option make us cant charging the phone.
Maybe some one expert in hardware mod can do better.

Hey could you explain what exactly did you uninstall and how?
After uninstalling it wireless charing stopped working or what did you mean by cant charge the phone?
Did it fully resolve the green screen issue?

Some people noticed that problem after upgrade Android 9 to 10.
At this moment we have some facts:
1) OLED saver temporary solves problem
2) disconnect NFC module solves problem, some people on xda and on the yt confirm that
3) heating back cover using heat gun can help - I Discovered that some weeks ago
Interesting comment from the yt:
Sour Words
Sorry to say this, but green screen issue is a hardware fault not something an update can fix. One of the updates from Samsung is causing the CPU to over heat and in return permanently damaging the oled screen. Not only that but also compromising the battery as well. The only fix is the replacement of both the oled screen and battery. This repair is entirely the fault of Samsung due to a faulty update that over works the CPU capacity. Therefore my advice is for you to return your device back to Samsung and lodge an assessment request. They charge a small fee for the assessment, but the entire repair should be compensated by Samsung. Be firm and keep the pressure via emailing them to insist on Samsung covering the repair costs. My Note 9 is almost 3 years old when green screen issue happened. They fixed the entire thing free of charge. But I kept firm and didn't let them bully me into charging me for the repairs, which was their fault in the first place. I must admit, my phone despite its age, is in perfect condition. Not a scratch on it. Which I know contributed winning my argument for the repairs. So if you have psychical damage, I doubt you will have a chance. Good luck to all who will give this successful method a go.

Galaxy Watch (R805u) sensors dead

I just bought the original Galaxy watch a few days ago, seemed like a great deal for a nice smartwatch. as i'm not very sporty, i'm just noticing now that all of the sensors are not working! Gyro, Accelerometer, HR . I have been at this for a couple of hours now researching if it's hardware related to see if i can get a refund or software problem. unfortunetly, most of the threads / forums i have been on are torn between both. some say that a couple of reboots fixed it and some say they had to service the watch to fix it. Does anybody have some final thoughts? Thank you!
Model : SM-R805u
latest software : Tizen 5.5.01 R805USQU1DUD1

Unfortunately, I have not seen a hardware fix for the Galaxy HR sensor around this forum...
Not sure what Samsung would charge to do it?
I had that watch and my HR sensor never worked correctly and flash green randomly...

After contacting the seller, I'm eligible for a full refund or an exchange, is the watch worth it? should I get an exchange and be happy about it or is the galaxy watch just prone to sensors failing? cause if so I wouldn't bother and will get a refund.
Thank you for the reply!

Myself, I would get the refund and check maybe the Galaxy Active 2 which I like and has good sensor's with more support here...

Question My Pixel 6 Pro died.

So, my 6 days old Pixel 6 Pro just died during using Camera. I just opened camera settings, it freezed, display got black and now I cannot turn it on. If I put charger, nothing shows up, just black unresponsive screen. Holding power button for 30 sec - nothing, holding power button + volume up also did not help. Its completely unresponsive.
Any help please?? I am from Czech republic, bought it from Google Germany. Warranty is technically not possible, I do not know how to do it since I do not live in Germany.

Does anything happen if you plug into a PC?

In another thread, u said u installed a moddee gcam, messed around with dev settings, after that your phone was dead.
Now u say, u are using camera and entered settings, and the phone died.
OPOmaniac said:
OK so my phone just DIED because of this modded Gcam. I donwloaded latest Gcam mentioned here above and then went to settings - developer settings - and tried to turn off "segmenter_use_darwinn_tpu_delegate" so I can use also front camera. Once i unticked that, my phone freezed, screen turned to black and its technically dead.

Yes, true, I opened Modded Gcam. But still, how it can kill my phone? Its just Gcam app. Other users did not have any problem to turn off the dev settings.

Do you have your phone rooted? According to comediiian, you tinkered a bit with your device. But as long as you run stock software, no modded/custom apk should be able to kill your phone.
You could always try to get warranty from Google, by using a forwarding service that you give Google to send in your device and get it back. Or you could use the address of a friend in Germany, if you have one.

Best refer to this and contact the seller of your phone.
Keep in mind though, that you will have to probably pay at least for shipping.
If the kernel crashed, it might be worth a try to wait a couple days until the battery runs out. Maybe you even have a Kernel Panic. It's just odd that the screen stays completely black. Wait at least 5 or 6 days. Then charge it, to see if anything turns on.

I am not rooted, all is stock. I spent like 2 hours with Google support chat and nothing helped. We tried to reach bootloader, recovery, changed cables for charging. Nothing helped.
I will send it for a repair through some forwarding company. Thank you for the tip!
I am just so disappointed. Had Oneplus 8 Pro before Pixel and this phone survived lot more than this Pixel. I think there must be some critical bug or something.

Please don't blame this gcam mod... It works perfectly and cannot "kill" a P6Pro.
It's either a bad luck or a bad usage.

So, I have some news.
It was not working for like 3 hours. I thought ok let's try to kill battery faster by putting it on the heater. I left it there for like 15 minutes. It got pretty hot and then I tried again boot to bootloader by volume down and power. On the third attempt it worked!! My phone is back again. I'm still not sure what happened, but as I said, it happened once I clicked that dev settings in Gcam. I know it works for others without an issue.

Congratulations! Thank god you didn't put it in a microwave oven - SCNR

in no way you will drain your battery faster by putting it on a heater. HOWEVER you'll certainly harm the li-ion cell and definitely reduce its max capacity by doing so.
Lithium cells DRAIN faster when cold, not when hot. That's why ebikes are useless in winter or cold countries

It's hard to mesure the exact impact on your battery... Probably you've lost some mAh of max capacity, maybe none.
Just enjoy it now but keep in mind heat is the enemy of li ion cells, a well as over charge/discharge.

You need to calm down before messing with things you don't fully understand.

P6P is my fourth Pixel phone. All 4 purchased at release.
My experience up to this point is that the phone as a offering has stability issues until the 3rd month of OTAs.
I dont really mod to heavily until the new year.

I had the same issue several days ago.
The screen went black and the phone won't vibrate when long pressing power bottom.
But actually I had WIFI hotspot turned on, and the hotspot was still accessible.
So I depress the power bottom for about 1 minutes and the phone just rebooted fine.

I had the exact same thing happen to mine. Except mine randomly rebooted about ten times over a few hours, then finally died.
Came back from the dead about an hour later.
By the way, there's quite a few peopel having random reboot issues. Seems like it's probably all connected to the black screen and temporarily dead scenarios.
The only people that have reached a solution are people that had the device replaced.
I'm going to be sending mine back. I think everyone else should as well - maybe it'll wake Google up to realizing they have a pretty major issue.
Why does my Pixel 6 Pro keep randomly rebooting? - Google Pixel Community

Pardon my confusion but what is the point of the gcam mod on a P6P?
1. I thought it was non-Pixel phones that benefit from modded gcam apps.
2. If the P6P has the best camera, what is being done to the gcam app to make it better or different to then reinstall on a P6P?

Question Samsung Galaxy A 32 4 G has a blank/black screen after Android 13 update. Any ideas?

Hi everyone, the phone was working fine, it was left to do an update for 3:00 in the morning. Couple hours later realized phone was blank/ black screen. Followed steps to do power and volume down and all it did was vibrate. It vibrates when plugged in. Two technicians looked at it and said it was a screen problem but a new screen was tried and it only showed a charging sign and after that it went blank again. I am wondering if it was android update that breaked the phone or is it something else. What specific hardware failure or is this software failure?
Any help would be greatly appreciated. Thank you.

My cousin had a similar issue with a black screen when they woke up - however their phone automatically reset itself and lost all data while updated to Android 13 overnight.

tried a firmware reflash?
anyways yes. samsung is a **** and has given me terrible experience with my a32. they dont pay attention to midrangers at all pushing out broken ota updates. My fingerprint sensor is now bricked permanently (no like actually. downgrading firmware doesnt help. its just gone. its fine physically. according to logs but something else broke ig). Then that stupid mobile data bug. where if i was using mobile data jt would disconnect from the cell towers and reconnect. as if there was no service. i saw many people have this issue. I was forced to use a gsi. One ui 5.0 is still pretty terrible for this thing. its not optimized at all. I am waiting for one ui 5.1. the final big update for this phone. Samsung seems to be pushing it out for all the phones. even cheaper than this phone. but looks like they forgot abt it.
