Although Sony’s attempt to turn the Xperia Z4 Tablet into a hybrid via the included keyboard dock is largely a failure, the Z4 is still one of the best 10in Android tablets available. It still has a few flaws, but if you want an Android-based alternative to the iPad then this is the tablet to get.

LG G4 vs Sony Xperia Z4 (Z3+) comparison: The Xperia Z4 wins on performance, but the LG G4 wins on looks and photography
Source: Tech Advisor EN→zh-CN Archive.org version
As we haven’t had any hands on time with the Sony Xperia Z4 as it is yet to be announced in the UK, we can’t say definitively which phone is better. With that being said, it depends on what you use your phone for – the LG G4 seems to be the better option for photography and general style/comfort, while the Z4 looks to be the more powerful of the two phones.

Sony Xperia Z4 preview

The Z4 family wasn't unveiled at CES 2015, obviously – and there's some talk that the Xperia Z4 may not even make a showing at Mobile World Congress 2015, which takes place in Barcelona from 2nd-5th March. Sony will undoubtedly be showing some new devices off at MWC (it's believed the company will hold a press conference on 2nd March, but that's yet to be confirmed), but many think the lack of rumours and leaks concerning the device suggest it's still a few months off being ready for launch.
