Display and Speaker Quality
Moving onto the display we have Sony giving the Xperia TX a nicely sized 4.55-inch display. The 4.55-inch display has a 1280x720 resolution, providing us with a pixel density of around 323ppi. The display is shatter-proof, and scratch-resistant to boot.
Sure, it's not Full HD, but it does the job. The Xperia TX's display does a great job at giving you a beautiful display to look at, and while it won't break records, it does its job pretty well.
The rear speaker on the Xperia TX is well sized, but it doesn't pack a powerful punch. This isn't a tablet, so I don't expect it to have the best quality speaker, but it would be nice for a company known for their audio products to have put a bit more effort into this section of the Xperia TX.
I'm not someone who has their music on speaker all of the time, but from time to time I'll take a phone call and have my hands busy so I'll go hands-free and turn the speaker on. The speech can sound quite atrocious at times, and speaking of bad audio, the earpiece on the Xperia TX can put out some shocking quality.
I was actually quite impressed with a mid-range handset from a company struggling in the market up until I started making phone calls. I do all of my testing on Telstra, who is Australia's best telco, and even then, it was bad.
