1. Jolla Hardware, the key factors against competitors

  • The Other Half - Extended back cover adding software to the phone. Four simple ones are introduced so far, enabling downloading content to the phone via an unique code in an NFC tag. However, people are looking forward for TOH's including hardware and adding phone's functionality. The Other Half can interact with the phone via I2C data port, NFC (wireless Near Field Communication port), Bluetooth and/or WLAN connection. DIY projects are already going on with extra OLED Screen, Hardware keyboard, wireless charging and more. Also Jolla might introduce some hardware related TOH's later, but the time is not yet. This might lift Jolla to it's own category in the smart phone markets.
  • No surface buttons - Gesture based Sailfish OS user interface is designed for use without any surface buttons. UI is quite intuitive, and after using this phone for a while other models might feel somewhat outdated.
  • I2C connection port - Enables interaction with several different hardware pieces, and is not yet introduced in too many smartphones. Officially Jolla doesn't use this port for anything yet, but there are a lot of possibilities. The Other Half is the most likely implementation, followed by set of docks on which the phone can be attached.

  • Superb sRGB color balance, comparable with iPhone 5 and HTC One
  • Average brightness and contrast
  • High white balance (8400K), making pure white to show slighlty blue
  • Screen is cold toned, colouring some photos to more blue

  • Front-facing camera is very small and demands a lot of light. Unusable in dark surrounding.
  • Video image quality reported as ok, sound quality is very poor

    - officlally supported format vFAT (single partition, 32 Gb size limit)
    - other supported formats ext4, btrfx (tested to work with 64 Gb)
  • Some uncertainty about 64GB MicroSD support. Possibly supported for several models. One 64GB model, Sundisk ultra, formatted to BTRFX (with Linux), is tested to work. Jolla's portuguese distributor informs support for 64GB cards.
Talk time
  • 2100mAh (3.8V, 7.98Wh)
  • microUSB charger (included)
    Input 100~240VAC 0.2A 50-60 Hz, Output 5VDC 1.0A

Durability, talk time
  • 10 hours with GSM
  • 9 hours with 3G/4G
Durability, standby time
  • 500 h all connections off
  • 24 - 48 hours in normal use

  • Battery quality seems just fine after seven months of use
Design &
  • Phone is split to two parts, back cover is called ”The Other Half”. Main part is black. 9 different colors are introduced to The Other Half, of which White, Cyan, Black and Dark Orange are introduced so far
  • Height: 131 mm
  • Width: 68 mm
  • Thickness: 9.9 mm
  • Weight: 141 g
  • Several comments about the design, opinions vary. Most are saying its simple and beautiful and right sized for hand. Few comments about cheap impression, possibly slippery back surface.
  •  Chipset: Snapdragon 400 (MSM8930AB, Qualcomm)

    CPU: Krait 300
    1.4GHz Dual Core
  • Average chip, standard model in this price group. Chipset's RF circuit offers large band variety for 2G/GSM, 3G/UMTS and 4G/LTE networks
  • GPU: Adreno 305
  • Modern graphic chip, should run modern games with decent performance with Jolla's screen resolution. Users have reported Android games to run as well as in their previous phones.
  • Sample video running GTA3 below
  • Mono speaker at the bottom
  • Mono speaker for phone calls
  • 3,5mm headphone connection 
    - Headphones not included
    - 4-pin plug, model AHJ
  • Microphone for phone calls
    and sound recording
  • Ambience microphone for
    active noise cancellation
  • Audio quality during phone calls is surprisingly good.
  • Audio quality during music playback suffers from single speaker
  • Some headphone models with a microphone are reported to add extra noise (might also be a headphone quality issue)
  • GSM (2G)
    - 850/900/1800/1900 Mhz

  • UMTS (3G)
    - 900/2100 Mhz

  • LTE (4G) **
    - 800/1800/2600 MHz

  • MICRO SIM Card
  • LTE (4G) coverage
  • **  LTE wireless service may not be available even if listed bands are supported by your carrier.
  • No FM radio
Wireless Connectivity

  • WLAN802.11 b/g/n 2.4GHz
    - Hardware chip also supports ac (5GHz), but it seems to be not enabled
  • Bluetooth 4.0 EDR HS
  • wireless NFC
    - limited to TOH connection
  • MicroUSB 2.0 HS
  • 3.5mm 4-pin audio jack
  • Extension interface for I2C data connectivity & power in/out. 
  • Phone is equipped with a large range of connection ports, but the only visible ones are microUSB and audio jack.
  • WLAN supports DLNA (Upnp media streaming)

  • Works as WiFi Hotspot. From settings it's possible to enable sharing of mobile internet to other devices via WLAN (tethering)
  • Proximity
  • Accelerometer
  • Gyro
  • E-compass
  • Ambient light
  • Phone is equipped with an average set of sensors in its price group. All sensors are accessible for both Sailfish and Android apps
Back cover

The Other Half
  • 4 official, several unofficial introduced 
  • TOH can interact with the phone via I2C, NFC, WiFi or Bluetooth. Those available are using NFC.
  • TOH can include software, changing the phone's functionality
  • TOH could include hardware, adding phone's features in the limits of the connection type, power and bandwidth)
  • Phone's ambience is changed automatically when TOH is connected to the phone for its first time. After the first time this automatic change can be disabled
  • The idea of The Other Half is to be an active, possibly hardware and/or software equipped cover which can add/affect the functionality of the phone. The Other Half could be e.g. a qwerty-keyboard, extra battery, more connection ports etc. The Other Half includes an unique ID recognized by the phone. Wireless NFC power in/out enables power to be transferred both ways between The Other Half and "The First Half", but both halves could also carry their own power source.
