Speaker stopped working

I was whatching a video on youtube and the sound was fine. Then I started whatching another video and suddenly the sound started to get more quiet and cracked and than was gone. Now when i start playing a song or a video it plays crackinh sound for a short time and then goes off completly.

I am on the newest firmware. Is this a software or hardware bug? And has anybody experienced somehting like this already?

Low speaker sound after putting my phone in water

Hello.

Some minutes ago I "washed" my phone with water, just a flow of warm water from the sink, less than 30 seconds. Approximately after 2 minutes I removed the back cover and dried it. After that, the speaker became very low and with bad quality sound, and progressively got louder and louder until it got back it's normal sound. Is that normal with this or any waterproof phone?

Thanks! Sorry if I don't explained myself very well, English is not my native language.

mpow speaker free offer.

I received an e-mail from someone claiming to work for mpow which I have never heard of.

They cited that they got my information from my XDA profile and wanted to send me a free speaker in exchange for an honest amazon and XDA review.

Do I trust this? Is someone trying to scam me? Sounds too good to be true. I never get offers like this.
