Umobile user here but no problems with 3g around my area.
Is the signal at your place weak ? if 3G is on and the signal is weak, could be due to that.

S4's camera also quite big right? A little hump on the back for a better camera or a flatter back for a lousy camera, I choose the former.
Erm... Actually... Sometimes bigger lens is for a bigger sensor. When the sensor is bigger, of course a bigger lens is needed to let light in. Aperture is another thing. Sensor size should be the main factor in controlling the "size" of a "camera" on a "phone".
Nokia Pureview 808 has a 1/1.2" sensor thus it's big like a monster

Lumia 1020 has a 1/1.5" or 2/3" sensor which is smaller so the hump is also smaller. Of course they slim down and redesigned other parts too. Best to ask nokia what they did

Xperia Z1 has a 1/2.3" sensor, which is the same size as the one used in QX10. The numbers may not sound like a huge difference but this 1/2.3" sensor is actually about a quarter of the size of the 1/1.2" sensor in 808.

So... The biggest controlling factor in the size of the camera on a phone is the sensor size. The lens size and thus the "hump" due to the camera depends on the sensor size.
iPhone/
One/S4 all using 1/3.2 or 1/3" sensor. Quite a lot smaller.
Other factors affecting include image stabilisation like the one in LG G2 and Lumia 1020. I'm referring to Optical Stabilisation, not software based stabilisation. Optical means there's a mechanism that compensates the sensor positioning with any movement or vibration due to our hands or body movement. S4/One/iPhone/Z1 all not equipped with this feature.
Not expert too. Just my understandings. Enjoy

EDIT: Seems like HTC One has OIS.

Did you update your Antutu score? Antutu is now on V4 with some new tests for "Multitask", "Dalvik" and some changes to the GPU test.

That's why I never like Samsung products,oversized and plastic design,but for the size,they really did a good job on galaxy s4,screen on s4 is amazing too,just the plastic design I dont like
