Lightweight, simple, and the battery life is amazing. The screen and appearance is super clear and bright. I recommend any galaxy phone, and Samsung product.

updated by Evan Kypreos - 29/04/2014 The Samsung Galaxy S4 was released as a high-end powerhouse back in 2013, but has since been superseded by the superb Galaxy S5 , which was followed itself by the Galaxy S6 .

Stunning 5-inch Full HD screen; Vast array of features; Powerful quad-core processor

Plastic design; A little bit expensive; Limited storage space

Phone was fine - looked good and worked fine over wifi. However it was not unclocked. I had to call At&T to get the unlocking code. Rest is all working fine.

Samsung's Galaxy S flagship enters its fourth iteration. Is four the magic number for Samsung?

Brilliant Full HD display; awesome camera and settings; powerful CPU; extensive features set; plenty of connectivity – NFC / MHL 2.0 / IR LED / LTE / Bluetooth 4; decent battery life; lightweight for size

Plasticky build quality; TouchWiz can be laggy; almost too many features and some like Smart Scroll don't work all that well; no way near enough onboard memory (16GB gets you just over 8GB

The Galaxy S4 is the fastest selling Samsung smartphone with 10 million units sold a month after its release. The handset has the tag line Life Companion, which is something you can't ignore as it's displayed on the lock screen, no matter what wallpaper you choose.

Phone is delivered before the given time. Packaging is very good. The phone is very good and light weight. Multiple extra and new functionality in this. Good internal memory. Don't think there is too much heating problem.

I purchased this phone for use with a T-Mobile family plan,inserted the SIM and memory card from my old phone and it was ready to go except that it would not send text messages to more than one contact at a time. Staff at the local T-Mobile store adjusted the settings and solved the problem.

Samsung's Galaxy S4: there's life in the old dog yet, now with added Lollipop

Unrivaled performance; Gorgeous display; Long-life battery; Good camera

Some gestures feel forced; No Octa-core at this time for the UK; Only 16GB for UK

worked for a few minutes, then freezes up. tried everything, downloaded updates, removed battery, to no avail will be returning it

I purchased this phone for my son and had it sent directly to him. I was very disappointed to find out that it won't work with his T-Mobile account as it states in the description!!
