We line a shift5.1 (left) up next to our Wiko Pulp 4G and see some similarities in their designs.
  • We line a shift5.1 (left) up next to our Wiko Pulp 4G and see some similarities in their designs.

  • With the Wiko's official length measuring 143.9 mm from top to bottom, it is only 0.1 mm shorter than the shift5.1.

  • We played a very simple game of smart phone Jenga with the phones to see how their widths and thickness...stack up to each other.

  • Both have the same width: 72 mm. The Pulp4G, on top, is 8.8 mm thick, yet it appears thinner than the 7 mm of the shift 5.1, possibly due to its curved edges.

  • The back cover has a different look but is the same kind of snap off.

  • Starting with the easily removable back cover we begin our journey towards the inside of this smartphone.

  • The user-removable Li-Po battery pops out with the move of a finger.

  • With 9.5 Wh (2500 mAh @ 3.8 V), it finds its place ahead of the iPhone 6 with 6.91 Wh (1810 mAh @ 3.82 V) and close behind the Galaxy S5 with 10.7 Wh (2800 mAh @ 3.85 V).

  • The mid frame is held in place by eleven Phillips screws.

  • Having removed those screws we use our trusty plastic opening tool to pry away the mid frame.

  • The only thing that remains inside the midframe is the rear facing loud speaker.

  • We are happy to see that it connects to the motherboard via spring contacts, allowing easy replacements in the future.

  • On the back of the display assembly we find the motherboard at the top section.

  • We take a moment to rejoice when we see all those ZIF connectors and bracket-covered press connectors. Then, start swiftly unlocking and unplugging them one by one.

  • First thing to come out is the small front facing camera which offers 5 megapixels.

  • Second in line is the big brother for the rear facing side which provides 13 megapixels for full HD video recording.

  • One of the display cables still clings to the motherboard but can be peeled off easily.

  • Just two more Phillips screws to unscrew and we can take the board out for a close inspection.

  • Behind the mother board we remove a rubber gasket that goes around the headphone jack and holds the lens for the LED flash.

  • Last part at the top section is the earpiece speaker.

  • At the bottom of the display assembly we find a daughter board with some components.

  • First we disconnect the cable coming from the motherboard and pry out the vibrator.

  • Next we peel off a small connector plate and disconnect the antenna cable.

  • Now we are ready to carefully pry out the daughter board itself which is glued in with some double sided tape.

Add Comment

  • Being able to detach the daughter board completely from the cable (and therefore from the mother board) is a big advantage over the shift5.1.

  • On the other hand, all of the components are soldered to the board, which makes repairing them individually a bit trickier.

    • USB port

    • Vibrator

    • Microphone

Add Comment

  • Speaking of the connection cable, we peel off the big sticker and find the second display cable running underneath and directly into the display itself.

  • With the sticker gone it is possible to also take away the power and volume buttons.

  • We stop here, leaving the connector cable in place.

  • We take a moment and sum up what we've discovered.

Final Thoughts
  • Replacing the battery is easy as pie with the swappable back cover.
  • This phone doesn't use excessive glue nor proprietary screws—we found only Phillips throughout the entirety.
  • Most of the components can be replaced separately.
  • The motherboard and daughterboard are connected via a detachable cable.
  • Unfortunately, the components on the daughterboard are soldered on, making a repair on an individual component difficult.
