Kyocera KX440 / KX444

Ok v fans i need some input on this. I just bought a lg 4700 on Tues of this week and it works great. The ptt is on point, FINALLY but it does take some time to get used to especially cause its new but i got the hang of it. But i have noticed is that the bars on this phone jump up and down alot, i don't lose signal or anything but its something that i ain't used to seeing being a verizon customer cause that feature is a nextel thing lol. Maybe i am being a little to worried and paranoid cause i have been paying extra attention to the phone with ptt and all and the phones features but i was just wondering if maybe its my phone in particular or is it the lg 4700 model itself is why cause the the other ptt phones don't interest me at all but if the perfomance is better on the kyo then i may consider it...Please if someone has any info please let me know asap...Thanks
