The Apple 128GB iPhone 6 Plus may suffer from an issue that can cause unexpected crashes and even result in the smartphone getting stuck in a boot loop, according to BusinessKorea.
Users who encounter the problem often have to get a replacement device and industry insiders believe they know what the problem is.
Some in the industry point out that considering that technical defects mainly occur in the 128GB version of the iPhone 6 Plus, there might be a problem in the controller IC of triple-level cell (TLC) NAND flash. TLC flash is a type of solid-state NAND flash memory that stores three bits of data per flash media cell. It can store two to three times as much data as a single-level cell (SLC) that stores one bit of data and a multi-level cell (MLC) solid-state flash memory that stores two bits of data. Moreover, TLC flash is more affordable. However, TLC is slower than SLC or MLC in reading and writing data. To reduce cost, Apple reportedly used TLC NAND flash in the 128GB version of the iPhone 6+ and some other models.
Assuming that the crash and boot looping problem is due to the TLC NAND Flash, it's possible that Apple will need to issue a recall, claim some observers. Notably, iOS 8.1 has not resolved the problem.
Samsung is apparently having issues with its 840 and 840 EVO solid state drives as well. Those drives are experience low read performance and also use TLC NAND flash. The company is said to be working on a firmware update.

iPhone 6 with 64 gigs of memory. Random resprings, but when chatting with Apple they said "your iPhone model are all designed with the same parts" but evidently it's not.
iPhone 6 Plus with 128GB memory ... two potential problem areas:
1. Mail sometimes crashes & comes up with blank or empty screen in last used app list
2. App that reads large .doc files occasionally says it can't read a file. Quitting the app and restarting usually clears it up. Have used this app for years and never had this problem until iPhone 6 Plus with 128GB memory.
My 1 day old iphone 6 128gb turned off today. None of the buttons worked and hard reset also failed.
When I plugged in the phone to a power source, the apple logo comes on for 3 secs and goes off for 3 secs. This cycle repeats continuously.
Sounds like I have a boot loop issue.
Yes there is a problem. My 128gb 6 crashes and/or reboots regularly. The wifi comes in and out. This is my 4th iPhone. It IS a real issue. Apple scanned my phone and has found each and every crash and reboot. They told me too backup my phone and reboot from a complete wash/restart. I still have the same issue after the reboot. During my chat with a representative I asked if this was a regular problem that they've been having. He stated that "it is regular enough to the extent that we think we have a solution. " FACT - the 128GB has problems. I'm not happy.
Slow wifi,faulty signal,crashing,freezing,random reboots,hairgate and bengate. This is what they do Plague iSheeps (Easily mislead by their own egos and think they are being unique and innovative. Often wrong but convinced they are correct)
This 128GB 6 Plus is driving me crazy !!!! Reboots after reboots. Plu it in and when you press the home button the screen stays black. Had to press Home+Power to get it back. Now is in an endless apple logo !!!!!!
Malware has a new add on, me! Whatever I do causes android to do any by durable crap ever existed than ever to frustrate the shit out of it. Never will be working decent. Extremely trustful now of android? I think never again!
Had the problem on my initial 6+ 128 GB, got a replacement. The problem's not as bad - it doesn't respring as often as the other phone - but it still exists.
The article really says it in the title. The RAM _may_ have problems. It's not definitive and may not even be true. At any rate it probably only affects certain phones while the rest are just fine.
It sounds like a problem which you're either gonna have right out of the box or never experience at all. I guess those of us who have had zero problems after a month or so probably will never have to worry about it.
