The Samsung S4 had many strong points going for it. It also has several weaknesses. So far during my testing I have experienced slow downs when opening apps, motion controls not always working especially in bright sunlight. But even more basic it’s a problem with using headphones.

There is an active thread over at XDA Developers detailing issues people are having whereby the S4 cannot provide enough current/power, which in turn causes the headphones to crack and pop.

Not a good state of affairs.
