My Carrier Services app from Google was updated last night from the Play Store. I'm wondering if this has anything to do with interface with towers and LTE signal? I restarted my Pixel 3 XL and now it seems my signal at home is more stable again and not jumping from 1 bar to 4 than back down to even zero bars at times. This could have just been temporary, so not declaring anything fixed until I try it when I get home tonight. Can't really tell at work because there is a Verizon transmitter on a street light pole only about a hundred feet away from my office window, so always 5 bars and a dBm level in the -60s here all the time.
Still poor signal after this update
