I have a client that has several Blackberrys with Foremen on site. The phones come back after a few days with buzzing in the earphone and speakerphone when someone's talking. We send them off for repair and then they work for a couple days. At first, I thought it was just a bad batch of Blackberrys, but now I know it's environment.
They work with concrete drilling and finishing so I'm assuming the fine dust is getting in.
We've worked with the cell rep to get OtterBoxes but they're not helping. Before the Blackberrys they had rubberized phones that had the same issue. We just assumed they were bad phones, but with this current issue, we're now sure it's not the phones themselves.
Anyone else run into this issue and conquered it?
