Intex Aqua Crystal Plus Full Specifications, Price and Review
The Intex Aqua Crystal Plus is one of the sleekest budget smartphones Intex ever produced, launched in May 2017. At just 7.4mm thin and weighing 140.2 grams, it is among the slimmest dual SIM 4G phones in its price category. Beyond its design, it packs a genuinely strong spec sheet for a budget device — a 13MP rear camera with dual LED flash, 5MP front camera, 296 PPI HD display, 2GB RAM, 16GB storage expandable to 128GB, USB OTG support and a gyroscope. It runs Android 7.0 Nougat on a MediaTek MTK6737 quad-core processor and supports 4G LTE Band 40 on both SIM slots. One important note — neither SIM slot supports 3G. This guide covers the complete Intex Aqua Crystal Plus specifications, design highlights and everything you need to know.
What Makes the Intex Aqua Crystal Plus Stand Out
The Aqua Crystal Plus combines three features that were rare together at its price point in 2017 — a genuinely slim body, a strong camera and USB OTG support. At 7.4mm thickness, it was thinner than many flagship phones of the time. The 13MP dual LED flash camera placed it alongside phones costing significantly more, and USB OTG — the ability to plug in USB drives and accessories directly — added real productivity value that most competing budget phones skipped. The inclusion of a gyroscope for VR compatibility and a sharp 296 PPI display rounded out a spec sheet well above the entry-level norm.

Intex Aqua Crystal Plus Design — 7.4mm Slim Profile
The defining physical characteristic of the Aqua Crystal Plus is its 7.4mm thickness. To put that in perspective, the iPhone 7 launched in 2016 measured 7.1mm — so the Crystal Plus was matching near-flagship thinness at a fraction of the price. At 140.2 grams and a 71.20mm width, it is easy to hold one-handed and slips effortlessly into any pocket. The 140mm height keeps it compact despite the 5-inch screen. The clean White and Black colour options complement the slim aesthetic without looking budget.
Intex Aqua Crystal Plus USB OTG — What You Can Do With It
USB OTG (On-The-Go) support means the Crystal Plus can act as a USB host — connecting external devices directly to the phone via an OTG adapter. Practical uses include:
- USB pen drives — transfer photos, documents and videos between the phone and a USB drive without a computer
- USB keyboards — type faster on documents or long messages
- USB mice — navigate the phone screen without touching it
- USB card readers — read microSD or SD cards directly
- USB game controllers — play compatible Android games with a physical controller
At the budget price point of the Crystal Plus, USB OTG was an uncommon inclusion — making it stand out against the Aqua Lions series and Aqua Trend Lite which all lacked OTG support.
Intex Aqua Crystal Plus Camera Review
The 13MP rear camera with dual LED flash is the Crystal Plus's strongest selling point. Dual LED flash produces warmer, more natural-toned low-light photos compared to the single LED flash on competing budget phones. In daylight the 13MP sensor captures detailed images suitable for social media, printing and zoom cropping. The 5MP front camera delivers sharp, usable selfies and handles WhatsApp video calls clearly — well above the 2MP front cameras common at this price range.
No 3G Support — What It Means
Like several other Intex 2017 budget phones, the Aqua Crystal Plus supports 4G LTE and 2G GSM only — there is no 3G on either SIM slot. In areas with strong 4G coverage from Airtel, Jio or Vodafone-Idea this is not noticeable. However in locations where 4G signal is weak the phone will drop to 2G speeds rather than falling back to 3G. For city and town users this is rarely an issue. For semi-urban or rural users it is worth factoring into the buying decision.
Is the Intex Aqua Crystal Plus Worth Buying in 2025?
The Intex Aqua Crystal Plus was genuinely impressive for its launch price in May 2017 — the combination of a 7.4mm slim body, 13MP camera, USB OTG, gyroscope and 296 PPI display was unusual at budget pricing. In 2025, Android 7.0 Nougat is unsupported and the MTK6737 struggles with modern apps. However if you find one second-hand for a very low price, it remains a capable secondary device. For a new purchase, the Realme C55, Redmi A3 or Samsung Galaxy A05 offer equivalent or better specs with current Android and full software support.
