MK Business News (via The Verge) reports that the Galaxy Note 2 will be announced at the IFA consumer electronics trade show in Germany in August, and then go on sale in October.
The news provider claims that the Galaxy Note 2 will have a 5.5-inch screen, up from 5.3 inches in the current model.
It has previously been suggested that the second Galaxy Note would have a faster quad-core processor and a 12-megapixel camera.
MK Business News feels that the device will come with the latest version of Android, 4.1 Jelly Bean, which will debut in Google's own Nexus 7 tablet this month.
However, it is thought unlikely that Samsung will fit the product with its unbreakable plane display (UBP) technology, which The Verge feels is the "precursor to future flexible displays".
Rather, UBP is expected to be introduced in a future tablet product from Samsung, either as part of the Galaxy Tab range or something different entirely.
