The tablet will, after a time of inactivity, go into standby mode. Restoring the tablet from standby mode involves holding the power button for 7 to 15 seconds until the Galaxy Tab splash screen is displayed on the screen. This tablet, like the Galaxy Tab Plus 7″, does not have any form of visual indicator showing whether the tablet is on, in standby or that a message was received. You have to turn on the tablet to check if an email was received which is fine in the grand scheme of things, but a visual indicator that can be seen from a distance would be nice.
The Galaxy Tab supports a large amount of audio and video formats including Mpeg4, H.264, H.265, Divx, AAC, WMA and AC-3. As an audio person myself, the lack of .WAV and .AIF formats is a bummer but many devices like this do not support those audio formats.
I picked up the Galaxy Tab 4 8.0 a couple of weeks ago... when it was on sale for $240. In all honestly, it's OK for a budget tablet... but bear in mind that it's much better when compared to all the other budget android tablets on the market.
