Jolla (smartphone) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jolla (smartphone) rather than just read about it. In short: The Jolla smartphone (or Jolla 1 or J1) is a smartphone produced by Jolla that runs the Sailfish OS. Following a successful crowdfunding campaign, it was manufactured in China and released on 27 November 2013.

Key takeaways

Jolla (smartphone) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jolla (smartphone) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jolla (smartphone) from memory before moving on to harder problems.

Reference excerpt

The Jolla smartphone (or Jolla 1 or J1) is a smartphone produced by Jolla that runs the Sailfish OS. Following a successful crowdfunding campaign, it was manufactured in China and released on 27 November 2013. The Jolla smartphone is no longer supported by Sailfish OS updates, the last update compatible being v3.4.0, released on 22 September 2020. Like the Nokia N9, the Jolla departed from the at that time conventional smartphone home button centric user interface and only featured a power button and a volume up and down rocker switch. Instead it relied on a swipe interface to close and switch between screens and applications would access a pulley menu to select menu items inside applications. In addition to the comparably limited number of native Sailfish applications available in the Jolla app store, the Jolla Phone featured the proprietary Alien Dalvik to provide support for installing Android-applications from F-Droid, Aurora Store (an opensource Google Play Store implementation) or others like Aptoide. The J1 smartphone is not to be confused with the Jolla Phone (2026), a successor device announced on 5 December 2025.

First unveiled device

On 20 May 2013, after IamTheOtherHalf internet campaign, Jolla unveiled the following details and design of their first device:

4.5 in IPS qHD (540×960) "Estrade" display Qualcomm Snapdragon 400 1.4 GHz dual-core 16 GB of storage memory microSD support 8 MPix AF camera, back 2 MPix camera, front 2100 mAh user-replaceable battery "The Other Half" Gesture-based Sailfish OS Android applications compliant MicroUSB 3.5 mm headphone jack Buttonless display, gesture navigation Device in English language version Qt, QML, HTML5 (see: Sailfish OS architecture) The Sailfish OS SDK was published at the end of February 2013. The Jolla smartphone is compatible with frequency bands in the ITU region 1: 4G (LTE) bands 3 (1800 MHz), 7 (2600 MHz) and 20 (800 MHz); 3G (WCDMA / UMTS) band 1 (2100 MHz), 8 (900 MHz); 2G (GSM) bands 850 MHz, 900 MHz, 1800 MHz, 1900 MHz. 4G and 3G will work in Europe but support is not guaranteed in other regions, even if a compatible frequency band is used.

Retail availability Jolla started shipping the phone in late November 2013. At first the phone could only be ordered on the web from within the European Union. The phone also became available in the stores of the Finnish carrier DNA on 11 December 2013. On 28 April 2014, the Jolla phone became available in Estonia at the outlets of Elisa Eesti, the first operator outside Finland to offer the phone in their shops. On 25 July 2014 Jolla opened the first Jolla store in Kazakhstan in association with Mobile Invest. On 12 August 2014 Jolla was launched in Hong Kong in a partnership with 3 Hong Kong. In September 2014, Jolla launched in India on e-retailer Snapdeal. In November 2014, Jolla launched in Russia.

Support Sailfish OS updates were provided for the Jolla 1 for 7 years. Other Linux distributions like postmarketOS continue to provide updates for the original Jolla phone but don't support calls, SMS or mobile data.

Jolla Phone (2026) The Jolla Phone (2026) is the successor to the J1, announced on 5 December 2025 and shown at Mobile World Congress 2026. It is marketed as an independent European Linux smartphone, emphasising privacy, long-term software support, and Android app compatibility without Google services.

Hardware The device is powered by a MediaTek Dimensity 7100 processor with 8 GB of LPDDR4X RAM and 256 GB of UFS 2.2 storage, expandable via microSD. The display is a 6.36" FullHD AMOLED panel at 390 ppi, protected by Gorilla Glass. The camera system consists of a 50 MP primary and 13 MP ultrawide on the rear. The 5,500 mAh battery is user-replaceable, continuing the J1 design tradition. A physical privacy switch disabling the microphone, camera, and Bluetooth is included, alongside a side-mounted fingerprint scanner. Connectivity includes 5G, Wi-Fi 6, Bluetooth 5.4, NFC, and dual nano-SIM. The Other Half (TOH) modular accessory interface returns with 7 pogo pins and I3C bus support, with full CAD specifications released to enable community hardware development.

Software The phone ships with Sailfish OS 5.2.11 Jolla guarantees a minimum of five years of OS updates. A review by Gadget Hacks noted that Sailfish OS treats privacy as a fundamental architectural principle, offering real-time visibility into network connections and granular data flow controls not available on mainstream platforms.

Release Pre-orders opened in December 2025 at €499, capped at 10,000 units, with the first batch selling out in under 48 hours. Retail pricing is expected at €599–699. The phone is initially available in the EU, UK, Norway, and Switzerland. The Associated Press covered the device at MWC 2026 as a privacy-focused handset for Europeans. First batch shipping was in July 2026.

Worked examples

Example 1 — a first encounter with Jolla (smartphone)

Start with the simplest possible case. Write down what Jolla (smartphone) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jolla (smartphone) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jolla (smartphone) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jolla (smartphone)

In research: Jolla (smartphone) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Jolla (smartphone) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Jolla (smartphone) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Discontinued smartphones, Linux-based devices, MeeGo devices, so understanding it makes those chapters shorter.
In everyday life: Look for Jolla (smartphone) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
