My sound stop working on my phone.

Do you have sound when using headphones? If so and a factory reset didn't work and assuming you tried playing with the settings then you probably going to need to open the device and see if the speaker is connected properly. If it is then it probably failed and you need to replace it. Shouldn't cost much if you DIY

I replaced my speaker and it still isn't working can anyone help me please

Go to settings go to do not disturb turn on sound

I have a Grand X Max 2 and I had taken it apart to replace the battery and charge port. My sound worked fine before I took it apart, I know for a fact I didn't break anything because I was too careful. Well when I put the speaker back in, I notice when putting the screws back in it just didn't sit flush and kept playing with it and taking it out, back in and finally, I guess it made contact somewhere and my sound came back on.
