Overview
What this part is
The loudspeaker in the vivo Y33s sits at the bottom of the phone and plays ringtones, alerts, media and hands-free calls. Water, dust and loud use can damage the speaker cone, so the sound becomes quiet, distorted or stops.
Before replacing it, check the volume, turn off Do Not Disturb and clean the speaker grille gently. If there is still no sound from the speaker but headphones or Bluetooth work, the speaker is the likely fault. The earpiece used for normal calls is a separate part.

FAQ
Frequently asked questions
Will this fit my Y33s?
Yes, if Settings › About phone shows Y33s. It does not fit the vivo Y33T, Y21s or Y33e.
Does it fit the vivo Y33T or Y21s?
No. They are different phones with different internal parts. This part is for the vivo Y33s only.
How do I know it is the speaker and not a software fault?
Restart the phone and play a video at full volume. If headphones or Bluetooth work but the speaker is silent or crackles, the speaker is the likely fault.
Is it made by vivo?
No. It is a brand new, OEM-quality loudspeaker made to fit the vivo Y33s, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The phone has to be opened, and the battery must be disconnected before the speaker is changed.
