Signal Issues on different devices

[randnet]

I have a Samsung S10 plus which I bought direct from Samsung and is unlocked. I recently got an O2 contract and it came with a Huawei P30 Pro. In the S10 plus I get 1 bar of 4g and the network is slow. In the Huawei I get full bars 4g and the network is a bit better. Same SIM in either phone and same house/location. I've reset the network settings of the S10 but the poor signal remains. Why would this be?

Run a speedtest on both

Could be a number of things @randnet.
Different phones have different antennas and are made of different materials.
Could be that they use a different signal band as well.

No faults in my area and when I raised it I was told no faults were found

Have you tried the speed tests?

I would be surprised if a UK Samsung S10 plus would be out performed on antenna by the Huawei p40 pro. In other areas I get full 4g but not at home on the S10, but i do on the p30 pro. The S10 even has 4g volte and WiFi calling even through it came from Samsung not O2 and doesn't run an O2 branded ROM, it's a BTU/BTU.

Got a DECT phone or doorbell, by any chance, @randnet? Or some other home device that's affecting the S10 antenna signal reception?

Any tips here of use?

I have a ring pro and a cordless phone, but when I was on three I had no signal Issues and the issue is present 75 feet away or more from the doorbell and phone down the end of my garden.
