Vivo Xplay 3S unveiled with a 6-inch 2K display, powerful audio amp and fingerprint reader
We came away rather impressed with the Vivo Xplay from China, so today's launch of its successor, the Xplay 3S (which is a bit odd as there was never an "Xplay 2"), is something that we've been looking forward to since the teaser way back in October. As mentioned before, this new Android phone is still the first to pack a 2K (2,560 x 1,440) display, which works out to be a ridiculously high 490ppi density on the 6-inch panel. Like other recent Vivo phones, you'll find a pair of dedicated audio chips on the Xplay 3S -- here you have ESS Technology's ES9018 DAC and Texas Instruments' OPA2604 amplifier, both of which are said to be the crème de la crème in their respective categories. This should go nicely with the built-in DTS Headphone:X feature that brings 7.1 or even 11.1 surround sound effect to your stereo headphones; plus Vivo's video streaming service already hosts about 200 Headphone:X-capable movies (along with over 400 movies in 1080p and over 1,000 movies in 720p), with more to be added each month.
Vivo Xplay boasts 5.7-inch 1080p screen, dedicated audio chips and nifty single-hand mode (video)
Another 1080p quad-core Android phone, you say? Well, there's a bit more to it. Launched by BBK spin-off Vivo in Beijing just now, this 5.7-inch Xplay goes one step further than its smaller X1 and X1S cousins by packing one extra audio chip and the OPA2604 operational amplifier from Texas Instruments in order to add extra oomph to Cirrus Logic's CS4398 DAC and CS8422 stereo asynchronous sample-rate converter -- both of which are featured on the X1 series. If you're a DIY audio enthusiast, you might have already tinkered with an OPA2604 while making your own headphone amplifier; so in other words, Vivo is trying to save you the hassle. Before we dive into the audio performance, let's quickly look at the rest of the phone first. Underneath the 500-nit LTPS display lies a Qualcomm Snapdragon 600 quad-core SoC (1.7GHz, 2GB RAM and Adreno 320 graphics engine), 16GB or 32GB of built-in storage, 3,400mAh battery and NFC. On the back you'll find a Sony 13-megapixel imager next to a pair of speakers (FLAC playback is supported natively), but flip the phone over and you'll be looking at a surprisingly generous 5-megapixel front-facing camera -- much like the one on Oppo's mid-range Ulike 2. Vivo's somehow managed to pack all of this into a 7.99mm-thick body with a screen bezel of just 2.3mm thick (which bests Pantech's thin-bezeled Vega Iron) and a large viewable-to-total area ratio of 75.11 percent. Alas, for 3G there's only WCDMA 2100, meaning the phone may have to rely more on GSM 850/900/1800/1900 or WiFi in many parts of the world. More after the break.
