This year looks to be no different and we should see the Galaxy Note 4 unveiled, supposedly on 3 September. And it probably won't be the only new product Samsung announces - that just wouldn't be Samsung style.
To whet your appetite, the Galaxy Note 4 is tipped to be the first 4K smartphone and a retina scanner.
Sony Xperia Z3 and Z3 Compact
Sony seems to be launching new flagship phone regularly now. The Xperia Z1 and Xperia Z2 were only months apart and the Xperia Z3 (D6653) is tipped to be unveiled at this year's IFA show. It will also be accompanied by a Z3 Compact - even though we haven't seen an Xperia Z2 Compact yet.
