People's creativity goes beyond that. A proof of this is a modification made on a Samsung Galaxy Note 2 which received a 8500 mAh battery that lasts about three months in standby mode and 256GB external memory.
It was connected to device an electronic filament for attaching a card slot that supports 256GB cards, enough capacity to store about 1.5 million mp3 files.
The author is a member of the famous XDA Developers forum who posted the photos of his modified device in a forum post.
The phone's owner also said he bought the memory card for $500 and the 8500 mAh battery on eBay. The model has undergone changes was a GT-N7102, Dual SIM version of the Galaxy Note 2 only sold in China.
Because of the battery size, the Galaxy Note 2 could not be closed with the traditional phone's cover which also needed adjustments (jerry-rigg) to close.
The modifications are not recommended by Samsung that says that the warranty is lost in these cases, but we thought it was cool, what did you think?
