Vanguard. Website works well enough. Rarely find a need to use the Android app - I use Mint primarily to keep an eye on my accounts, and Google Now for timely updates of certain stocks/funds.
I use Vanguard as well, most of my trades with them are their ETFs or Mutual Funds so it's no fee (I don't trade very often, maybe every 6 months to rebalance).
My stocks are predominantly in Fidelity because I have their 2%-back-on-everything AMEX, which rolls into my Fidelity Brokerage account. $7.95 trades which I think is pretty standard for mega-bank retail trades without trade volume or account balance discounts.
No, but at the same time I've never needed their CS. The one time I've called was to inform of international travel. Total time spent on the call was less than 5 minutes. Did the same thing for my Visa card and that took over 15.
My only other interaction with them is when they send me new cards to activate, like if my card is going to expire or they want to issue me a new number. Activation is all automated and takes 2 minutes.
Fidelity brokerage I think is a separate service organization, and have had no problems with them either about account questions.
Same here, although I primarily use it because trading Vanguard ETFs is free, which is mostly what's in my portfolio. Other brokers probably provide better tools, Vanguard's views are adequate but nothing special really. They do have pretty great customer service though, the few times I have had to call the person on the other end was always very knowledgeable.
