Owners of 128 GB iPhone 6 and 6 Plus Models Reporting Crashing and Boot Loop Issues

Could they have been using the 16 or 64GB models sporting MLCs? The article didn't seem to mention which models was tested?

I'd agree that most users wouldn't be able to tell the difference in performance but cutting corners on a premium product is just bad taste. Like Porsche swapping out the Michelin tires on their Cayenne Turbo with $69.99 Nexens cos most suburban drivers wouldn't be able to tell the difference.

The problem with TLC in a phone isn't so much performance as it is endurance. Apple recently bought an Israeli company specialized in NAND error correction, probably for the use of cheap TLC NAND in their premium devices. But even with the best error correction and wear leveling, TLC has a shorter lifespan than MLC.

Also, I'd guess TLC is only in the 128 GB models due to performance. By interleaving the 128 GB of TLC NAND they can probably match or exceed the performance of MLC NAND in tiny amounts like 16 GB.

This is pure speculation, but maybe the issue is with Apple's new NAND controller using the specialized error correction developed by that Israeli company. For all we know, this is Apple's first attempt at an in house NAND controller, or at least their first attempt at a more complex NAND controller. Just thinking out loud here - we don't even know yet that the rebootloop is a hardware issue.
 
I'll share my story here with you. I have a 16GB plus. For 3 weeks it has been perfect. Yesterday i tried launching Facebook but it was crashing and taking me back to the springboard. I tried one more time and the phone rebooted, apple logo, then again, and then again. 3 times. When it finally woke up, i tried Facebook again, then team stream and some other apps and i saw a red screen popping out, boom, restart. Tried quitting all apps, rebooting manually, and launching some app and then boom, blue screen and reboot. And no app would launch. Not apple apps, not 3rd party apps, nothing. Scared the living **** out of me. Didn't want to hard reset.. So i went to sleep. This morning i decided to hard reset it, connected it to iTunes, clicked restore and it said "first disable find my iPhone". I took the phone in the hand and everything was in english (mine is in italian). I checked it out and changed it to Italian and since then everything has been flawless! The only thing that has changed was language and location based services.. Like iAD was turned on again and other default stuff that i disabled on day1. WTF was that???? I was ready to drive to my apple store and than this happened. I have 5 kernel panics and 1 gpu restart. Should i go and exchange it? Or wait IF it does the same thing?

Btw, i took a screenshot to remember which apps i had in which order and 2 screenshots were normal, the last one was the top half of the screen ok, and the bottom half was black. Like it only captured to top half of the screen. Man, scary stuff, lol.

I Have a problem with my iPhone 6 (64 GB) using the Music App. I have iTunes Match and "show all files" turned off, so I see only Tracks stored on the device. But after skipping a few tracks, the Music App won't play the song (even if the song worked recently) but otherwise act normal (you can press Play/Pause or skip the tracks; but the songs just don't start).. restarting the App won't help but sometimes waiting around 2 minutes or rebooting the iPhone let's me play the songs. Maybe a Software Bug? I experienced it since updating to iOS 8.1

This is normal with iTunes Match and has been the case for me since I've had it. Even on iOS 7. It's good when it works but it still has some serious bugs with automatically skipping or not playing songs that are actually stored on the device. Sometimes I even get stutters or hangups with it trying to buffer a track that is already downloaded to the device and occasionally have to toggle airplane mode on/off to force it to play the song.

Thanks a lot. I'm an iTunes Match user since Day 1 (in Germany). Never had such issues in all those years.
 
What is a "large app library"? I read something about this last week and they said it was happening when people had over 700 apps installed. I have a 6plus 128GB and I haven't had any issues, but I don't have anywhere near 700 apps installed.

I have about 200 apps and I consider that a lot. But I have no problems. I never say stuff about what other people put on their phone, its their business, but 700 apps is asking for trouble.
 
Experiencing frequent crashing in YouTube app, several websites (YouTube, bodybuilding.com, muscles fitness.com, Google, news.com.au - pattern seems to be anything with embedded media), sometimes macrumors. Webpage crashes, white screen with the new grey banner 'this webpage has crashed and will now be reloaded'.

In the MLC 16GB iP6+ at least, the NAND contains the ECC processing. This makes for a very fast flash. This leaves the rest of the controlling work to be done by the CPU. This is nothing new for Apple (I've just learned) as this controller in the CPU also runs the flash encryption. The A4 did it. I'm not sure about the SoC in the 3g s.

So with TLC, it would still be a controller in the CPU (SoC), but perhaps not the same controller algorithms used when MLC NAND is present. Perhaps something is going wrong with the 128GB NAND that is causing the whole SoC to reset? Perhaps the SoC is failing on wear leveling? There will be a lot of that with TLC.
 
So, now we get CrashGate too.

Plus BendGate.

And CallGate.

And DeleteGate.

And DistortionGate.

Wow, I have actually lost count.

Steve Jobs must be turning in his grave. His obsesssive attention to details has been replaced by poor quality control.

I dont have itunes match and and thats what is happening to me is just playing the songs that i bought from itunes store and skipping all other songs
 
I've got a 128Gb 6 Plus and I've had big problems with my iTunes 'music' app! It forgets my songs, delete songs from my playlists and causes my car stereo to crash (via USB).
 
Hi. I have a 64 gb iphone 6 and I had this problem. I took it back it Apple and am waiting for a replacement. Another person was there with the same problem and they just restored their phone not even discussing a replacement.
 
I have 6 Plus 64GB and it's been working great, 8.1 working fine.

I don't doubt this has happened to some, but it seems to be a very small amount.

My only question is, how long do you put off going to the Genius Bar after experiencing this, or any other problem??? It always seems that some people complain about an issue, yet have not been the to Genius Bar.

The people who did go to Genius Bar got their phones replaced. So it sounds like a hardware issue, that's effecting a small amount of people and Apple is taking of it.:cool:

It is a non issue because there is no credible evidence of a design failure here.

NTSB: "We've had 20 of your Firestone Sports II tires blow after they reach 100mph in the last 3 days."

Firestone: "We have reviewed the design, integrity of the tire & re-evaluated the tire testing. We found no flaws."

NTSB: "Ok but tires are still blowing up."

Firestone: "Notify us when you have more details to provide. The information you provided shows that those consumers are breaking the law & we do not provide support for criminals."

That's the same exact thing people said when iPhone 6+'s where reported to bend easily.
Guess what?
There's a huge thread in the other forum with a good percentage of people with bent/warped 6+'s.

The issue is real.
