If anyone is getting poor 4G signal coverage due to location, being indoors, on the train etc I have been entering into Engineering mode and setting my network selection to 'LTE only', it has been providing a steady signal strength so I may continue using the internet/play games etc at a desirable speed even in conditions where the signal would revert to 3G or 3G coverage was really poor.
1. Enter Engineering mode -Type *#*#3646633#*#* into dialer or download: https://play.google.com/store/ap ... eerStarter&hl=en_GB (If using app click MTK Settings)
2. Land on Telephony Tab > Scroll down to 'Network Selecting'
3. Choose designated 4G Sim (SIM1 OR SIM2)
4. Set preferred network type to 'LTE only'
5. Exit - signal will take a few seconds to refresh
In 'LTE only' mode you will not be able to recieve or make calls so make sure you revert back to 4G/3G/2G(auto) or 4G/3G.Once I am in a location where I know 4G has good coverage I revert back to 4G/3G.
Hopefully this becomes useful for others.
