2/3 G signal strength

---

Is it possible to get the mobile signal strength on GT 7.7
I had try lots of ways but can't successful.

What you mean "get"? To get it as a function in your own app's code or just you want to see it?
Turn off WiFi and you'll see strength bars in notification popup (on the place where you usually see WiFi signal bars).

There are plenty of apps like this one that display signal info:

You can also get that in the About page of the device settings. What exactly are you after?

nooooo, use this one instead, this Widget is better

It's all the same data obtained from the phone. A widget tends to suck battery and performance so that's why I recommended a simpler app. Since there are a ton of them, it's really incumbent on the end user to decide what they like.

All of that apps doesn't work on SGS2/Tab7.7 (Exynos-based chipsets).
No, they work (run), but unable to show correct signal level due to a "bug" in modem FW. They always show +85dbm. So the only way to see correct signal strength is the system signal meter in statusbar.

Any way to update the modem driver to fix the Bug ?

Don't think so. Samsung does not care about it - still not fixed even on SGS2, which is already on the market for a long time. Maybe it will be fixed with ICS release, nobody knows.
