Without knowing any of the specifics--how long you've been in business, how much you've raised so far, the number of employees, the market opportunity, competitive landscape, runway, how much experience you and your other founder had, how much experience the CTO had, etc, etc, etc--I can't imagine trying to give you any advice other than to...
1) Ask yourself these questions:
* Did I get into this for a quick payday or to build a business?
* How could I best contribute to the business if I stayed? Is that something I want to do?
* Are these people I'd want to stay and work with indefinitely?
* If I had to walk away today and give up all my stock, what dollar value would I put on my contributions (both assets and effort) to date?
* If I had to walk away today, how much cash would I need to comfortably cover the downtime until I find what's next?
2) Talk to a personal attorney who has some experience working with start-ups, fundraising, etc. Someone who's negotiated founder contracts and separation agreements.
3) If you know them well enough, talk to the board, advisors, and/or investors who participated in your last round and ask their advice.
If they want you to leave after the next round, then that probably needs to be part of the conversations with potential investors. If you're a founder and have a large chunk of stock, it's not unlikely that they'd want to buy most or all of it back from you with proceeds from the next round.
"Perhaps you should fix those mistakes in your "% Change" column... Looks like some rows show a decrease when there is an increase (for example C in 2012 is 4.9 and 4.10 in 2013, and % change here is -16% ...)."
I have to remember to add "What's the % change between 4.9 and 4.10?" to my list of tech interview questions.
You can also go pseudo-base-5, which will get you 99 and it's relatively easy to know where you are: right hand fingers are 1s, right hand thumb is 5, left hand fingers are 10s, left hand thumb is 50.

I wonder how much this reflects a split in the market between people who treat their smartphone like a computer vs those who treat it like an appliance. When I buy a microwave, a TV, a stereo, a car, or pretty much any other consumer product, I have no expectation that the UI will ever change. I won't have people moving the knobs on my cars dashboard, or "flattening" the UI on my microwave. Android is on OS used primarily by phone manufacturers who still want to control the user experience (e.g. TouchWiz), and who are selling that phone as an appliance.
Complaining that one can't put Kit Kat on a Nexus S seems a bit like complaining that you can't add HDMI input on your old Sony Trinitron or put ABS on my 1990 Miata.
