Duration: 45 min.

Steps: 20 Steps

In this guide, we’ll walk you through the process of swapping out the faulty proximity sensor on your Galaxy S4 Active. If your screen refuses to dim while you’re chatting away, it’s time for a little repair magic! If you need help, you can always schedule a repair.

Step 1

– There are some nifty little clips holding the back cover snug against the chassis. Look for a small dip right above the power button. With a gentle touch from your fingernail or a spudger, you can pop the cover up right there.

– Carefully detach the back cover from the chassis.

– Now, go ahead and lift off the back cover.

Step 2

– Time to give that battery a gentle nudge! Use your fingers to lift it out. Don’t worry, there’s a little pocket in the chassis just waiting to help you out.

– Go ahead and lift out the battery!

Step 3

– Let’s kick things off by popping out the SIM card and microSD card. You’ve got this!

Step 4

– Grab your trusty steel laboratory spatula and let’s get those four metal shields off! Gently slide the spatula under the covers and give them a little nudge to pop them out of their cozy spots in the chassis. You’ve got this!

Step 5

– Time to get those twelve Phillips screws out of the way! They’re holding the chassis to the display, and we need them free. Grab a container to keep them safe and sound. You’re looking for 12 x 3.9 mm Phillips screws. Let’s do this!

Step 6

– The chassis isn’t just hanging out with the display; it’s got some sneaky little hooks keeping it in place. Grab your trusty steel spatula and let’s get that chassis detached!

– Slide the spatula right between the display and the chassis. A great starting point is around the power button—it’s like finding the sweet spot!

– Now, gently glide the spatula all the way around the device. You’re doing great!

– Once you’ve successfully detached the chassis, go ahead and lift it off the display. You’re one step closer to a happy device!

Step 7

– First up, let’s unplug that sub-board’s plug contact. Easy peasy!

– Next, disconnect the antenna cable. It’s just a little tug and you’re good to go!

– Time to disconnect the display connection. Just a quick pull and it’s off!

– Now, let’s unplug the brightness sensor. A little flick and it’s free!

– Don’t forget to disconnect the proximity sensor. Just a gentle nudge will do the trick!

– Finally, unplug the front camera connection. You’re almost there!

Step 8

– The logic board is snugly attached to the rear camera and the vibration motor. Gently nudge the logic board towards the USB port to set it free.

– Now, with care, lift the logic board up.

– Finally, remove the logic board from its cozy home in the enclosure.

Step 9

– Let’s kick things off by unscrewing that Phillips screw to free the cover plate. This little guy is holding down the speaker, proximity sensor, and front camera, so it’s kind of important! You’re looking for one 3.0 mm Phillips screw here.

– Now, gently lift off the cover from the enclosure. Easy peasy!

Step 10

– Carefully take out the proximity sensor from its cozy little home in the enclosure.

Step 11

– Position the new proximity sensor in the enclosure.

Step 12

– Position the cover plate in the enclosure.

– Fasten the cover with the Phillips screw. The cover plate holds the speaker, proximity sensor and front camera in place.1 x 3.0 mm Phillips screw

Step 13

– Gently nestle the logic board into its cozy spot in the enclosure.

– Keep an eye out for any pesky plug connections trying to sneak under the logic board—don’t let them get stuck!

– The logic board has a special bonding moment with the rear camera and vibration motor attachments. Just give it a gentle nudge towards the top of the enclosure until it clicks firmly into place.

Step 14

– Connect the front camera to the logic board.

– Connect the logic board to the proximity sensor.

– Connect the brightness sensor.

– Connect the display.

– Connect the logic board to the antenna cable.

– Connect the sub-board.

Step 15

– The chassis isn’t just hanging out with the display; it’s got some sneaky little hooks keeping it in place. Give the chassis a gentle push with your fingers to snug it up against the display.

– Now, press that chassis down firmly across the whole device.
