This will be my last post on signal strength..The Samsung S-10 plus has some signal issues that can only be fixed by a software update as reported by android police..Every phone can have that issue and they will fix it sooner or later with that update..This is why updates are so important on every phone..
Google(Android) gives there updates to Samsung/Verizon/LG etc then those companies go through the original update and modify it to there own specs..Sometimes it is good and other times like this post,it turns out bad for Samsung.
The Galaxy S10+ may be one of the best phones you can buy right now, but based on recent reports and our own testing, there's at least one metric where it falls behind: signal strength. It turns out that a combination of your carrier, the frequency you're connected to, and even going caseless can have a huge impact on the quality of its cellular connection, resulting in measurably lower signal strength compared to other recent phones in our testing.
The issue manifests simply: The reported signal strength on Samsung's Galaxy S10+ is reduced compared to other devices, with devices on some carriers such as Sprint being affected more than others. Even customers of AT&T and T-Mobile, however, are occasionally reporting reduced signal strength. Furthermore, in our own tests, merely holding the phone "wrong" while it isn't in a case can make a big dent in signal strength.
