Lean on me harder? The phone was working after they replaced the screen with the old motherboard installed. The fact that I rooted it and blew the e fuse has nothing to do with the broken screen. The screen is breaking on devices without root as well.

I would accept it if it was because of something I did, but here it's 100% Samsung's fault for selling me a device with defective screen.
[Samsung Galaxy S21 Ultra] blackhawk:
Meh, you did do something😖

By loading a custom kernel that could (or did) cause hardware damage. The firmware sets many of the hardware's operating parameters.

You automatically void the warranty and for good reasons. You have in the manufacturer's eyes you intentionally damage it by altering its instruction set.

So don't play coy, you rolled the dice and got snake eyes. The price was pretty cheap considering Samsung could have refused to service it altogether.

What's really going to bake your noodle is if Samsung recycled the mobo by replacing the fried chipset and reused it🤣
[Samsung Galaxy S21 Ultra] mati11233:
"altering its instruction set" "fried chipset" "damage it" Holly.... you really don't know what you are talking about. I don't know if you are trolling or just really don't know much about this topic.

Samsung clearly admitted that they messed up during production and sold me a defective screen as they replaced the screen free of charge. Besides the device was rooted 6 months before the screen died
[Samsung Galaxy S21 Ultra] blackhawk:
You altered its instruction set from stock, right?

Nuff said. You altered it's operational parameters by doing so... if this was the cause of the failure is unknown. You added variables that didn't need to be there.

Firmware failures can take days, weeks even years to manifest themselves.

Rootkits sometimes fry hardware too.

So yeah continue as you were... are you feeling lucky today?🤣

My S21+ too went dead after just 1 month. The phone does vibrate when I switch it on or off but nothing on screen. Went to Samsung service station and they say the screen needs to be replaced. I reached out to Samsung team and fought hard with them to get the device replaced. Now they say the device is out of stock.

With so many ppl complaining about the screen issue and then device going out of stock, has Samsung messed it again and trying to hide the issue?
[Samsung Galaxy S21 Ultra] blackhawk:
Demand a full refund from these jokers.

When Sammy gets it right, it's good.

Otherwise it's a bomb.
[Samsung Galaxy S21 Ultra] brianjsw:
My phone from the initial pre-order just died today too with the exact same symptom. Was literally working fine. Set it down, came back 5 minutes later and no display. Went to UBREAKIFIX and they told me they are seeing lots of these. They also said there isn't an official announcement or bulletin from Samsung they are aware of. They noted that the new replacement displays they are receiving all have a yellow sticker on them saying 'improved'. So something seems afoot definitely.
[Samsung Galaxy S21 Ultra] Srbija2012:
2 people = serious issue?
[Samsung Galaxy S21 Ultra] Srbija2012:
What an absolute load of BS.

Altered its instructions? Operational parameters? You come here and post absolute dribble. No part of modifying the bootloader alters any instruction for the display, stop with the keyboard warriorism.

Ive had, as have others, faulty displays replaced on rooted devices. Samsung have no evidence to suggest that ROOT (SW based alter) causes display malfunctions or damage., otherwise they wouldn't have replaced them!!

Firmware failures can take days, weeks even years to manifest themselves. <-- please do enlighten us...
[Samsung Galaxy S21 Ultra] blackhawk:
Allow me to retort...

That model has a lot of issues. I doubt you damaged it. Samsung warranty is unpredictable at best. I go out of my way to give them an excuse and avoid dealing with them if at all possible.

These devices can run very well stock; why by a $1+G device if you don't like it? The stock firmware is intergrated to that hardware and tested as such.

As for the hardware instruction set, if you altered the factory set parameters you can damage the hardware, it's a simple concept.

Don't be so naive. If this was or wasn't done I don't have a crystal ball and doubt do you. It's a risk you take loading 3rd party firmware. -If- you don't alter the stock kernel or drivers the risk is lower but that's part of why people root devices, isn't it?

Taking seconds, minutes, hours, days, weeks, whatever to fail is dependent on how much the hardware's limits were exceeded and how close to tolerance the components are. Some devices will fail while others may not. Instruction sets are generally on the conservative side of the component limits to offset individual component tolerance deviations. You see that in PC overclocking, it's well know to the point where identical processors are tested/graded by the manufacturer and sold as such. The better ones are guaranteed to run at higher frequencies.

Had my S21U Exynos in March and was running fine even after latest upgrade to Android 12 and OneUi 4. Until the BSOD happens today(27 Nov) just about an hour ago after charging my phone. The screen is just pitch black and just will not turn on and the only thing visible is the side panel. I know my phone is still active as it is still connected to DeX on my laptop. I had read in a Facebook Forum from users that has the same issue. I tried their workaround that is by reverting the Dark Mode to Light Mode. I tried this several times back and forth and finally the screen turns on. I then increase the brightness to about 50% and deactivated the Adaptive Brightness setting. So far its working fine for now. I have also reported this issue in the Samsung Members app.
[Samsung Galaxy S21 Ultra] genjo_sanzo:
Today 28 Nov it happens again but this time around its less than 2 minutes of trying to turn on the device. I then proceeded to do the same workaround as I did yesterday and the screen lights up again.
[Samsung Galaxy S21 Ultra] mehra1:
MIne s21 plus just got the same problem and now its 1.5 years old. Not sure how much it will cost now to get a replacement.
[Samsung Galaxy S21 Ultra] blackhawk:
Since Samsung's has gone to variable refresh rate displays the failure rate has gone up it appears. Not good. I would lean on Samsung like a cheap suit to get done for no charge or at least at wholesale cost.

Hello, please help me I’m stuck in a bad situation, I have s21 ultra I’m facing a problem now , when I turn on the phone it shows the Samsung logo for 2 second and the screen goes off and phone is running inside , but the screen stays active in downloading mode , I tried all methods of resetting hard reset soft reset nothing is working please help me
[Samsung Galaxy S21 Ultra] z@yd_@hmed:
Yes screen works in download mode only
[Samsung Galaxy S21 Ultra] Rstment ^m^:
Your best bet is having it replaced... if not under warrranty then open up the phone and disconnect the screen cable then reconnect it ( Phone MUST be off - or you'll fry the motherboard )

If this doesn't work idk... flash the latest stable system update and repeat the process above ( Maybe even try powering the phone on without screen connected , power it off - by disconnecting battery - reconnect screen then power it back on )
[Samsung Galaxy S21 Ultra] z@yd_@hmed:
Thank you, but tried every method and also checked with a new display still the same issue. Phone power on and show Samsung logo for 2 seconds and screen goes off , but it’s displaying the screen in download mode , anyone who have faced this problem and got the fix ?
[Samsung Galaxy S21 Ultra] Rstment ^m^:
You need to reflash the software , if that still doesn't work then you know there's something wrong with the motherboard
[Samsung Galaxy S21 Ultra] z@yd_@hmed:
Yes I reflashed the software with Odin 3 and still the same problem
[Samsung Galaxy S21 Ultra] Rstment ^m^:
Can't help you... taking it to a good repair center ( specialized in motherboard repair ) should give you more insight

Good luck
[Samsung Galaxy S21 Ultra] z@yd_@hmed:
where to post questions in this forum

sure thTs the only option left im just scared of losing my data it’s like a nightmare
[Samsung Galaxy S21 Ultra] Rstment ^m^:
Does twrp eixist for your phone? You can backup like that ( search twrp backup broken screen for guides )

Or search google "How to enable usb debugging broken screen" - once you have adb enabled use tool like https://github.com/Genymobile/scrcpy to display phone image on your pc

Another way of enabling usb debugging is by flashing modified boot.img with build.prop changed to include these lines:

persist.service.adb.enable=1

persist.service.debuggable=1

persist.sys.usb.config=mtp,adb

( Better use google again to find a detailed tutorial on how to make a modified boot.img )

If you have usb c to hdmi cable you can connect to tv and view the phone screen like that - if touch still works navigate and enable usb debugging , if touch doesn't work you'll need keyboard or mouse
[Samsung Galaxy S21 Ultra] z@yd_@hmed:
Thank you so much bro , sure will Definitely try this ❤️
[Samsung Galaxy S21 Ultra] blackhawk:
Try refreshing the stock firmware, possible corruption.

If that fails it's likely a bad mobo.
[Samsung Galaxy S21 Ultra] z@yd_@hmed:
Tried everything nothing worked
[Samsung Galaxy S21 Ultra] blackhawk:
If you reflashed it and the problem persists, it's hardware.

If so how did it go?
[Huawei Mate 20 X Questions & Answers] jbmc83:
haven't done that (yet), but it was good to see that here in Singapore there is a Huawei service center that offers original battery replacement for a reasonable price.

we recently did a battery replacement for my gf's Moto G5 Plus, but so far looks like the (non-original) replacement isn't up to par...
[Huawei Mate 20 X Questions & Answers] Deanro:
There are starred reviews on aliexpress that reflect customer experiences with battery replacement. From what I've read these customers are well content with the renewed battery strength. You might want to take a look.
[Huawei Mate 20 X Questions & Answers] Deleted member 11523331:
No absolutely not needed.. Why when the phone will last the longest of all smartphones?
[Huawei Mate 20 X Questions & Answers] jbmc83:
depends how long and how hard uve been using it i guess. im currently down to roughly 4500 mAh, thus 90% of the original 5000 mAh capacity. still super happy with the SOT im getting though :)
[Huawei Mate 20 X Questions & Answers] Deanro:
That's far from accurate. There are phones with 6000 even 18,000 mah capacities. For example the Samsung Galaxy M31 has 6000 mah.

Mah numbers stated on batteries are just that, numbers. There are phones with even lower battery capacities that outlast higher battery capacity phones by several hours including the 20x as yt video showdowns between different phones demonstrate. No doubt, although a higher mah indicates greater battery life generally, relatively speaking, battery life overall depends more on what's determined by the interaction among software, voltage and hardware than what's stated on the battery.
[Huawei Mate 20 X Questions & Answers] blackhawk:
It's not just a drop in mAh's that warrant replacement. If there's any detected battery swelling the battery needs replaced asap.

The risk of a thermal runaway event increases dramatically with a damaged (swollen) Li battery.

This can happen even with a new battery.

The swelling can possibly damage the phone as well, without going supernova, by putting pressure on surrounding components... like the display.
[Huawei Mate 20 X Questions & Answers] Deanro:
Your dropped battery capacity isn't surprising but natural during the course of its use. My own battery has a capacity of just shy of 4700, somewhere in the neighborhood of 4630 last time I checked.

As you stated, your battery was at one point at a full 5000 mah and lost 10% of its capacity to what's presently 4500. But just so you know, your battery is not precisely filled to 5000 mah right out the factory. In reality its always less than whats stated; the reason being is that batteries differ in capacity during manufacturing mostly to cut costs. Battery manufacturers round the numbers to the nearest hundredth or thousandth to read batteries easier. Hope this helps.
[Huawei Mate 20 X Questions & Answers] Deanro:
Correct. This is why within the battery, cells are damaged which skip proper readings by the amount equal to the amount of juice generated by the lost, damaged cell.
[Huawei Mate 20 X Questions & Answers] blackhawk:
This is what a typical Li polymer battery used in cell phones looks like.

There's no hard case to contain it so any internal pressure immediately becomes an issue.

Swelling in the cell it's self will distort the structure of the cell and alter it permanently.

A sealed plastic bag surrounds it to hold any vented gases or goo.

It's just one cell and it's rolled construction is similar to a capacitor.

It's alarmingly flimsy... and packed with energy.
[Huawei Mate 20 X Questions & Answers] Deleted member 11523331:
Sorry man you not right

No there is no any smartphone with 6000mAh Batteey you too naive to believe lies and fake statements from china :D That is complete crap what you saying that lower capacity batt will outperform battery with larger capacity.. :LOL: Where do you live boy?

I will explain you about the batteries ok? ;)

As I know about batteries. Li-ion batteries has best density

Speaking of cell density batteries there would have to be new design and new technology.

For more battery cells you obviously need larger battery ! THAT'S WHY Mate 20 X / Honor Note 10 battery is the largest from all.

Battery Size

Although higher-capacity batteries generally last longer than lower-capacity ones, they are not always suitable for use in every device. To achieve a higher capacity, battery makers often have to fit more cells into each battery. Cells are the parts of a battery in which the chemical reaction needed to generate electricity happens. Increasing a battery's cell count can in turn increase both the size and weight of the battery, making it unsuitable for use in slimline devices such as smaller cell phones and netbooks. The temperature and speed of electrical current discharge affects the overall capacity of the battery. Poorly made batteries often heat up too quickly resulting in performance issues or degraded capacity.

To calculate a battery's life, divide the capacity of the battery by the current required by the object it powers. For example, imagine that you have two batteries for your cell phone, one with a capacity of 1000 mAh and one with a capacity of 2000 mAh, and that your phone requires a current of 200 mA to function. The first battery would power the phone for five hours, as 1000 divided by 200 equals five. But the second battery would power the phone for ten hours, as it has double the capacity of the first. While a larger number indicates battery power, larger mAh batteries may not be better if it is a poor quality battery. It simply means it can store more power.

Cell phone battery life is heavily dependent on the way in which you use the phone. The more features you run at the same time on your phone, the more current your phone requires and the quicker the battery's capacity drains. This is why using WiFi or running complex games on your phone drains the battery quickly. As such, a battery with a high capacity that is used to power a smartphone might last for less time than a low-capacity battery that powers a basic device.
[Huawei Mate 20 X Questions & Answers] Deleted member 11523331:
The battery will most likely get swollen becuse stupid ppl will take their phones into shower where is humid and steam and it will obviously get inside phone remember 20X isn't ip68 and even ip68 phones can suffer if the phone is in humidity environment...

OR

If the phone is in freezing cold place so the frost will pass through no matter how proof device is and then when you take it to warm environment straight away inside phone and battery the freeze will turn into water and short and create battery to swollen becuse of the reaction ...

You're right about the waterproofing, don't test it.

It might work...

In my case it wasn't abused and I was lucky it didn't take out my Note 10+'s display.

Heat and/or rapid discharging can cause it.

Or a bad copy from the factory.

Or simply accumulative damage over time and insults. I live in the desert so heat is omnipresent. I try to keep it cool especially when charging.

My phone has never been cold charged or even close to damp. Cold charging (>40°F) can trigger a run away thermal event or cause permanent damage.

Charging in temperatures under 72°F can cause Li plating which permanently degrades the cell.

Youre not bright when it comes to the subject of battery and 1000% wrong yet again. The Samsung Galaxy M31 is korean which you mistakingly think is chinese and has a 6000 mah battery which I'm sure youre too afraid to verify in google. The Helio P70 has a 18000 mah battery which of course you deny since you dont operate in our reality.

Longer capacity batteries dont guarantee a longer lasting life than lower capacity ones. Case in point, the iphone xr with 2940 mah equals the note 9 with 4000 mah as this yt video proves:

then advanced wipe - and wipe everything except system.

then i flashed again the latest version of twrp , magisk , rmm bypass, and no-verify-opt-encrypt 6.0

when i tried to flash no-verify-opt-encrypt 6.0 i got the error "failed to mount preload invaild argument"

however, my phone is rooted, and it is working.

is it should be an issue ?

how can i fix it?
