The signal of my xz2 compact is very unstable.

[Harrier]

I started using xz2 compact these days, maybe a bit late, but I really like its design and size. But in use I found that its signal is very unstable. Frequent switching of 4G and 4G+ signals is a typical problem. I did a variety of attempts, including a factory reset, but it didn't work. Even if enter safe mode, the problem remains. So I don't think it's the problem caused by the application. By the way, I have upgraded the system to the latest 52.0.A.8.25. Does anyone know how to solve or improve this problem?

I upgraded the system software to the latest 52.0.A.8.50 but the problem remains. The same environment, the same SIM card, the signal is very stable on other mobile phones(huawei p20, iphone7).

I tested it for a long time and found that even if the signal is not stable, it rarely leads to network disconnection. It seems that just the signal bar shows the problem, he may be too sensitive.

I found that the xperia xz2 released in China had been fixed for the signal bar problem. I don't know if the same correction is being used in the international version, but I hope the official can investigate the problem with the signal bar display.
