Sounds and resolution has changed in a negative way. Please respond!

Dear Supercell

Since a few days the sounds on my clash of clans have changed. All the buildings besides the Air sweeper, the DE storage and the x-bows sound like walls, when clicked on. Also, collecting dark elixir from my drills sounds different too.
When I put my troops down, they all sound the same. But that's just slightly annoying. What is REALLY annoying me, is the that the resolution on my HTC-one mini 2 has dropped dramatically and it really has a impact on my motivation to play the game and on my overall experience.
I've noticed me playing less over the last couple of days (not wanting to boost etc.).
The game feels cheaper and a bit strange.

I hope that you can give me an answer and possibly fix this. I've asked clanmates of me and they DON'T have that problem. So it seems to be a bug.

Thank you very much in advance for your answer.
With kind regards x tildertyp

I'm having these problems too...

This is also happening to me. Most buildings make a "wall" sound when I click on them and there are other weird stuff like that while I'm attacking.
This has never happened to me until I updated the game.
