Welcome to the Android Forums.
What you are experiencing is support forum psychosis. You're going crazy thinking there are problems with every phone out there, when in truth the real problems are rather rare. What happens is that when someone has a problem they find their way here to find a solution, adding to the appearance of problems everywhere.
I won't say there are no problems, because there are. Some are hardware shortcomings and others are software related, but most can be overcome with a little knowledge and elbow grease. Occasionally you will get a device with a manufacturing defect, but that can happen with any product. Android wouldn't have become the global smartphone leader in such a short time if it didn't have something going for it.
It's commendable that you are doing a little research before you buy. That will eliminate a barrel full of disappointment in the long run.
Now, if you could tell us what you expect from a smartphone, and what your preferences are in terms of size, carrier and budget, then we can make some recommendations.
