# Major Hardware Issue Could Prompt iPhone 6 Plus Recall

Reports indicated that the 128GB iPhone 6 Plus repeatedly restarted after more than 700 apps were installed, even after upgrading to iOS 8.1. The article linked the issue to a possible fault involving TLC NAND flash memory and raised the prospect of a recall.

## In brief

The iPhone 6 Plus could face a recall if its reported hardware problem was confirmed to involve TLC NAND flash. Reports described repeated restarts on the 128GB model with more than 700 apps installed, while analysts suggested the flash memory controller IC might be responsible.

[iPhone 6 Plus](<https://www.accordhk.com/>) has faced continuing controversy. Its large 5.5-inch screen helped it capture a share of the large-screen smartphone market and win over users, but persistent quality issues have caused users considerable frustration. Following the recent issue of bending cases, another hardware problem has emerged, this time involving flash memory, and it could potentially lead to an iPhone 6 Plus recall.

Earlier reports indicated that when more than 700 [apps](</services/#apps>) are installed on the 128GB iPhone 6 Plus, the system repeatedly restarts. Even upgrading to iOS 8.1 does not resolve the issue. The problem may be related to the iPhone 6 Plus switching to cheaper triple-level cell (TLC) NAND flash memory.

Previous iPhones mostly used more stable but also more expensive multi-level cell (MLC) NAND flash memory, while TLC NAND flash had been used in some iPads.

However, [Apple ](<https://www.accordhk.com/app-developers/>)switched to TLC NAND flash in the iPhone for the first time this year to reduce costs, mainly in the high-capacity 128GB iPhone 6 Plus. TLC is cheaper and offers two to three times more capacity than single-level cell (SLC) and multi-level cell (MLC) memory. However, TLC has slower read and write speeds, and analysts suggested that the problem might lie in the controller IC for the TLC NAND flash.

If the problem is ultimately confirmed to lie in the TLC NAND flash, Apple may have to recall all iPhone 6 Plus devices already sold, which would represent another major setback for the company.

## Frequently asked questions

### What problem was reported with the 128GB iPhone 6 Plus?

Reports indicated that the system repeatedly restarted when more than 700 apps were installed. Upgrading to iOS 8.1 reportedly did not resolve the issue.

### What might have caused the repeated restarts?

The article suggested a possible connection to the switch to cheaper TLC NAND flash memory. Analysts indicated that the problem might lie in its controller IC.

### Why did Apple switch to TLC NAND flash memory?

According to the article, Apple made the switch to reduce costs, mainly in the 128GB iPhone 6 Plus. TLC was described as cheaper and offering greater capacity than SLC and MLC memory, although its read and write speeds were slower.

### Did the article confirm an iPhone 6 Plus recall?

No. It said Apple might have to recall all iPhone 6 Plus devices already sold if the problem was ultimately confirmed to lie in the TLC NAND flash.
