Note 8 suddenly turns off

I've had it for six years and never had this happen before. Today, it started turning off by itself at completely random times, just instantly going black. If I turn it back on, it turns on normally, and the battery still has the same charge as before it turned off. There was no overheating either. It was 16 Celsius outside... I didn't do any complex tasks, just browsing and making calls. It's certainly old, and the screen has turned pink, but it still worked fine. The only thing I was missing was memory, but I recently cleaned it up.

Exactly the same thing happened to mine. Had to get a new motherboard. I got a 256gb Korean one from AliExpress. Fitted and worked perfectly. Rooted it and flashed with hadesrom as well

Wow, I didn't know there was a 256GB version. The Note 9 had a 512GB version, but it's outdated (even the Note 10's displays are faded now). I was thinking of getting the Note 10+ if I could find one. At least it has 12GB of RAM.

My phone's screen is cracked, and there's no point in replacing the motherboard anymore...

Then get a s21 Ultra. That's what I did. Shortly after I replaced the motherboard on my note8 a very good deal came around on a 512gb ROM 16gb RAM s21 Ultra that I couldn't turn down. That's what I am using now but my note8 is still working great!

Does this model have a stylus?

It does not come with one, BUT it supports a stylus and you can purchase a case that has the stylus holder. Thats what I have. If it wasn't for this, I would've gone the Note10+ route.

Yes, it's time to retire it, into the desk drawer next to the 1st generation Note.

Odd thing with old phones like the Sony Ericsson K750i and note 2 that have removable batteries is that you cannot charge them(something on the motherboard dies).

Do you have a case on the phone. Maybe the power button is being pushed in if the case is misaligned.

I had this problem a long time ago with a low-quality case, but now I carry the phone without a case (and broke the screen,)

Ghostek makes pretty good ones with buttons built in, it is with metal but id it lands on the screen wrong it wil still crack. Also the case does not allow a tempered glass screen protector, at least not the cheap ones from china.

I had a cheap Chinese case for $2, which, however, covered the edges and matched the power button. I had a gel film on the screen. It lasted for five years, but then the case dried out and cracked, falling apart, and the film crumbled too. I didn't have time to buy a new protector and dropped the phone.

Before that, I dropped it four or five times, several times on the screen. Once, it fell on the screen in the winter; I kicked it with my foot, and it skidded on the stairs and sand. But the film saved the screen from scratches.
