Problems with X8?

[#1]

I got my X8 last Wednesday, and have been exploring it and faced a few problems so far:

1. network signal reception is rather poorly: compared to my previous G900, or other SE devices, and even iphone with the same SIM card(s), it is relatively bad. Wonder if it is this individual phone or X8 in general?

2. Maps: possiby due to the poor signal reception the map does not load at all while in vehicle; if this bad how can it be used as a navigator?? Also while using Maps the phone froze twice, and both times I had to take out the battery to restart the phone. Has anybody else experienced the same problem?

I have rang the customer centre to discuss the signal reception problem, and now am considering for a swap while the guarantee lasts.
