A55 signal always drops to edge and stays there

[frazam]

Just got my A55 last Saturday, and I thought all was fine til I went out the house.

In places I frequent where I always get a steady 5g signal with my Xiaomi and 4g signal with my old A50, the A55 goes to 5g then goes to edge. It stays on edge unless I turn airplane mode on/off or reboot the phone. 

I switched the sim cards from my Xiaomi and A55, but the Xiaomi still maintains a full 5g signal while the A55 goes to edge and stays there. Both sims are on the same network too. 

Is there something I need to tweak? Or is this a defective unit?

Edit: posting on my A55 and of course it didn't post the first time due to network issues. This is frustrating

It's absolute ***. Absolutely WORST signal I've ever had in any device. It shows 5G and sends data 200 kB/s. Samsung S10 in the same place reaches 8 MB/s.

Same with my A55, it drops to 4g+ in areas where I have full 5G signal with my Poco F3.

it started the same issue to my unit this week. sim1 would go from 4g to edge (sim carrier has no 3g and 5g signal in my area), and sim2 would lose volte function then from 5g to 3g. at first i thought it was sim2 fault (recently converted it from physical sim to esim) but realized why also sim1. even restarting the phone the problem would come back later on. my unit is on the march security update.
