What are the best and worst things about the Samsung Galaxy s3?

in my opinion just one bad thing, its build quality its all made up of plastic material

but all other things are good

bye have a nice day and merry christmas

Worst: Unlike the iPhone 4S, which is universally lauded as beautiful handset, the S3 splits opinion. Although the author finds the device to be well crafted, other members of the team don’t like the plastic look. The S3 has a plastic feel when compared with unibody handsets such as the iPhone 4S and HTC One X. There is no escaping this. However, the general consensus seems to be the white version looks far superior to the pebble blue edition.

3. Fiddly brightness controls

A feature we found to be particularly irritating was the “auto adjusting screen power”, which regularly adjusted the brightness of the screen depending on the lighting. We found this to be too sensitive, especially when using the device on the train and in a car.

To make things more complicated the internet app has its own brightness controls. We found the automatic brightness setting to be inadequate so we changed this manually.

2. Wireless charging not available

The S3 supports wireless charging, but the kit has been delayed until September. When it eventually pops up, the charging kit is unlikely to be cheap either. This is disappointing and Samsung could have been the manufacturer to usher in wireless charging out-of-the-box.

Biggest problem: Apple launched the Siri voice-activated personal assistant on the iPhone 4S, and, although it generated excitement, it is a feature that has been confined to use in social environments. We don't mind Samsung adding this feature, but the execution with S-Voice is poor. Although the device is able to perform simple tasks, asking the device to do anything else is difficult.

Performance when answering questions was inconsistent. S-Voice was able to answer an easy question such as “what is the tallest mountain in the world?”. But when asked to provide the "weather in Iraq", it could only tell us what it is like in Leicester Square. Indeed, when we asked S-Voice the weather for any region, it always returned Leicester Square.

Best: Unrivalled performance

The S3 is the quickest and most responsive smartphone tested. Samsung has manufactured its own Exynos 1.4GHz quad-core processor using a 32nm process to improve efficiency. The firm has also added in 1GB of RAM.

Opening and switching between apps is lag free. The device also comes with a Pop up play feature, which allows users to carry on watching a video and use other applications such as messages. This is an excellent feature and allows PC-like multitasking as opposed to just “app switching”.

2. Battery: Samsung has nailed a key feature with the inclusion of the mammoth 2100mAh battery, and has managed to keep the handset weight down to 133g. The first smartphone to break the 12-hour barrier in our real-world usage test, and it did not disappoint. During the test, corporate email, Gmail and Twitter accounts were set to push content throughout the day and we also carried out a range of tasks including web browsing and watching a 40 minute video. Brightness was cranked up to the maximum level, Wi-Fi remained off and battery saver was turned off.

The S3 powered through the entire 12 hour day and still had 27 per cent of the battery remaining. The screen was responsible for 52 per cent of the battery drain, mobile standby took up 19 per cent, voice calls 9 per cent and the Android OS 7 per cent.

With the ability to turn on a multitude of power saving options, it is possible to strength the battery life well beyond the 12 hour mark.

1. Screen

The Super AMOLED HD display with 1280 x 720 resolution is the best hardware feature. At 4.8in, it’s big, but not overkill like the Galaxy Note (5.3in). So, you can still hold it to your ear without feeling embarrassed.On paper the display 306ppi pixel density may not match the iPhone 4S (326ppi), but this is irrelevant. The S3 renders colours superbly – replicating shades which will make your eyes water. It’s great for watching HD movies and videos from YouTube, but equally for viewing PDFs, word documents and emails, because the text is razor sharp.Samsung has even built in a control for users who don’t like oversaturated colours. The ‘natural’ pre-set tones alters the colour temperature and contrast. We found this setting to be easy on the eye on the commute home, after a long day of using screens.
