The coating gets also loose on my Aqua Fish. As the plastic underneath is black it doesn't mind for me. I think it was more difficult for Intex to produce a smooth plastic surface and so they gave it a coating. Only bad thing are the coating pieces at your desk, in your car or whereever ;-)

Next thing: The Intex logo is getting loose. I hope sometimes all letters will fall off so there will be a clean look again...

I've got a 3M screen protection. As we know, the screen is not made of glass and I think this is the first you should do when getting a brand new Aqua Fish/Jolla C.

The power Button seems to wear over time. I have to press it a bit harder to get some reaction.

Sometimes, I hear that cell modem distortion sound from the speaker. This can be an electrical fault or maybe it can be fixed by software.

That's all I think. Apart from that, I find the Aqua Fish is a nice daily phone. I cannot use LTE with Vodafone in Germany, but I don't need it. 3G is fast enough for me.
