You can consider getting the Qin F22 Pro.

I wanted to use this but it made my DT2W and lift to wake completely useless. It’s a pity because these are the only two issues I had with it.

I’ve literally never heard of Keen until this article.

I assume that you are talking about connectivity issues?

On a side note, I used an international base S22 and had terrible battery life when I was in the US. However, that’s likely due to the chip’s inefficiencies rather the connectivity issues. I had strong 4G/5G reception on T-Mobile.
