Introduction

Use this guide to replace the display of your Sony Xperia Z3.

To reassemble the device, follow this guide in reverse order and apply new adhesive where needed.

  1. Heat the back cover of your Xperia Z3 to loosen the adhesive underneath.
    • Heat the back cover of your Xperia Z3 to loosen the adhesive underneath.

    • Lift up the back cover with a suction handle and put an opening pick in the gap.

    • Move the pick carefully around the edges to loosen the adhesive on every side of the phone.

    • Don't put the pick in too deep under the back cover to not damage any parts inside the phone.

    How hot (how many C) should the iOpener be? I think it would be safer / more accurate to heat the iOpener in an oven with accurate temperature control.

    Careful here. The back cover cracked in two places. Once when I exerted pressure with the suction handle, and in the corner when moving the pick around the edges- even though I was very gentle. The battery was adhered firmly to the back cover.

    I cracked the back cover instantly. Make sure to buy a spare one before opening!

  2. After the adhesive around the egdes is loosened, pull up the back cover with your suction handle.
    • After the adhesive around the egdes is loosened, pull up the back cover with your suction handle.

    • Use a tweezer to pull out two black straps that are attached to two pieces of adhesive right on the battery.

    Careful during this bit. My old Z3 back cover couldn’t take it and split into lots of pieces (probably weakened over the years!). Just order a replacement for £3 off ebay before doing it ;-)

    • Gently pull out both of the black straps with the adhesive tabs.

    • Never pull out the straps upwards but always sideways. It can easily happen that you rupture the adhesive tabs right in between. In this case use a plastic card to pry off the back cover carefully, use heat if necessary !

    • Use a spudger on the left side of the frame to lever out the battery.

      • Be careful with the spudger—there are cables beneath the battery!

    • Remove the battery.

    • Unscrew the two Phillips #00 screws.

    • Use a tweezer to remove the adhesive strip of the loudspeaker assembly.

    • Pull up the metal clamp at the upper end of the loudspeaker assembly by using a tweezer and remove it.

    • Lift up the main flex cable covering the loudspeaker assembly with a Spudger

      • Take care to not damage the loudspeaker. The flex cable is attached to the assembly with adhesive and is a little bit sticky.

      • Lift up the whole loudspeaker assembly with a spudger and remove it.

    • Use an iOpener to loosen the adhesive underneath the display of your phone.

      • The stickiest areas are in the upper and lower area of your display. After cooling down, the adhesive will stick to the mid frame again. If needed reheat it.

      • After the adhesive at the lower end of your phone is loosened, pull up the display with your suction handle and insert an opening pick.

    • After loosening the adhesive in the lower area of your phone with an opening pick, insert an other opening pick approximately 1/16 of an inch and slide it along both sides of the phone to sparate the display from the frame.

      • Take care! While you're loosening the adhesive beneath the upper part of your phone, do not insert the opening pick too deep between the display and the mid frame. The earpiece is placed right beneath the "Sony" Logo and you don't want to damage it.

    • After loosening all the adhesive beneath the display twist the opening pick in the lower end of your phone a little bit to lift up the display.

    • To fully remove the display off your phone, you need to thread the display flex cable through the gap of the mid frame in the bottom end of your phone.

      • Take care of all the connectors of the main flex cable hanging around and of course the display flex cable itself.

    • If you didn't manage to keep the earpiece in its place while removing the display you have to remove it now.

      • The earpiece is extremely sticky and might be damaged while removing it.

    • Use an iOpener to soften the glue, then use an opening pick to slide between the the earpiece and the display and carefully take off the earpiece speaker.

      • When reassembling put the earpiece speaker back on the frontside of your phone.

    The picture is misleading. If you try to remove the speaker with tweezers just how the picture depicts it, you will most likely rip it in two peaces like I did. Warming it up is absolutely necessary, but then just use a pick to loosen the adhesive underneath the speaker and remove it afterwards. For reassembly you will then need some new adhesive sticker for the speaker, but those are pretty cheap.

What website is best to obtain a genuine screen and back from?

Do I need a new adhesive sticker to put the backcover back on?

Josua - Reply

The back cover won’t fall off Josua but I would definitely recommend new adhesive!

Dominik Schnabelrauch -

But only for the phone to be waterproof? Because mine is definitely not waterproof anymore.. So I think this wouldn’t make any difference.

Josua -

In our case the back cover just held semi tight to the phone assembly without new adhesive. It could happen that the back cover falls off, when you pull the phone out of your pocket or you drop it. New adhesive also protects your phone from dust which can cause overheating.

Dominik Schnabelrauch -

Should adhesive also be used on the new front display? or will the old adhesive be enough by reheating it and letting it cool with the new display on the phone?

My Z3’s screen was “glitching,” as in the phone’s screen showed static noise from time to time. It was hard for me to do anything on the device, and the problem would be fixed for a really short amount of time by knocking on the phone (I know, that’s a very bad solution). Do you suppose that the cause of this weird “glitch” is an inconsistency of the LCD’s connector? Or can it be some other internal issue? How should I properly handle this problem?
