ABOUT THE A30 TABLET: You'll find both a 3.5mm headphone jack and a micro USB charging port on top of the tablet, along with an IR blaster that lets you use it as a remote control when using the pre-installed CloserTV app. The right side has a clicky power button and volume rocker, and the left has a flap that gives you access to a SIM and microSD card slot, the latter of which worked fine with a 256GB card. There's a single mono speaker on the back, in the bottom right corner. It's not very loud and the location makes it very easy to accidentally muffle it with your hand. The Fire HD 8 and Tab3 8 both have better-sounding front-facing stereo speakers. The A30's 8-inch, 189-pixel-per-inch, 1,280-by-800 IPS display is pretty standard at this price point. It matches the HD 8 and Tab3 8, giving you fairly crisp text and video that's free from pixelation except on close inspection. Colors can seem a little washed out when viewed from the side, but looking straight ahead you won't have an issue.
