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. 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. We take a moment to rejoice when we see all those ZIF connectors and bracket-covered press connectors.

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.

This is what makes the Wiko Pulp 4G tick: MSM8916 CPU with an ARMv8 Cortex-A53

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. 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.

  • 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.

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.

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 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.
