The iPhone 7 Plus uses both the primary loudspeaker and the earpiece speaker together to produce stereo sound. Use this guide to replace the primary loudspeaker at the bottom of the phone only. Replacing this speaker can help resolve issues such as loss of sound, poor sound quality, and distorted sound.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 3.4 mm pentalobe screws at the bottom edge of the iPhone.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  2. Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
    • Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

  3. Apply a suction cup to the lower half  of the front panel, just above the home button. Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.
    • Apply a suction cup to the lower half of the front panel, just above the home button.

    • Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.

  4. Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Insert the flat end of a spudger into the gap. The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, rock the screen up and down to weaken the adhesive until you can fit a spudger inside.

    • While pulling up on the suction cup, twist the spudger to widen the opening between the screen and rear case.

  5. Insert the flat end of the spudger between the front panel and the rear case at the lower left edge of the iPhone. Slide the spudger up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place. Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

  11. Pull the display assembly slightly away from the top edge of the phone to disengage the clips holding it to the rear case. Open the iPhone by swinging the display up from the left side, like the back cover of a book. Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

  15. Make sure the battery is disconnected before you disconnect or reconnect the cables in this step. Use the flat end of a spudger or a fingernail to disconnect the two lower display connectors by prying them straight up from their sockets on the logic board. To re-attach press connectors, press down on one end until it clicks into place, then repeat on the other end. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

Thanks Jeff, this guide helped me complete the repair, even the fiddly bits with the diversity antennae. Oh the joy of hearing the “by the seaside “ ringtone from a previously mute iPhone. :D
