4G dropping to 3G
I have an unlocked Samsung Galaxy Note 9 and live in an area with 4G volte calling availability but not regular 4G. My query is, when I first switch on my phone I get 4G at full strength, I can make a 4G call and all is OK, however after about 3 minutes of having 4G (from switch on or coming out out of airplane mode), my phone will switch to 3G 'H+' on about 2 bars and stay there. The phone is set to auto select LTE/3G/2G, is there any reason why 3G is getting priority over 4G?

Hi @bpshanahan
So your smartphone will use a whole bunch of parameters to determine which mobile tower and what frequency (3G/4G ect.) to latch onto.
It's not just signal strength but also the quality of the signal. I.e heavy traffic on a particular frequency in that area can slow the speed down considerably.
Usually your phone will choose the best frequency for you, if that means dropping to 3G but getting better quality transfer of data.
You can of course set your priority yourself to 4G and see if you notice any change in quality. As your on the move tho i would recommend keeping it on auto.
Hope that helps :)
