The phone chooses networks based on strength and stuff.
It picks the best available network, going down the list from 4G, to 3G, then 2G depending on reception.

Re: why change network 3g to 2g

You only can get 4G if
- Your phone support this . Does it the 730 (dual sim) or the 735 (single sim)?
- You have a data plan which includes 4G (so your provider must have a 4G network and you have to "pay" for this.) So do you have a 4G dataplan.
- The area where your are must have 4G coverage. Even if you area has 4G there can be "dead" spot like in buildings ect. So if you move around you never have 4G
- If your phone does not "see" 4G than it automatically change to 3 or 2G that isnot a mistake from your phone.

Because I do not have answeres on above questions I do not know why you do not have 4G
