Increasing Signal Strength

[russy]

Is there a way to increase the signal strength on this phone? I have also SGS4 and there is a hidden menu from where you can change some values and the reception is better, but battery lasts a bit less. I need this because in my area the 4G signal is a bit weak and the phone always goes in H+ mode, which ia annoying. If I choose only 4G network then it works but I have no coverage in some areas.

You may try using dialer and dial *#*#4636#*#* later choose phone information 1 or 2 depends on which slot you put the sim card for data connection and later choose LTE only
