    Hi, i use a 9930 sprint, 7.1 Bundle 1737 (v.7.1.0.580, Platform 5.10.429). OTA indicates
    that's the latest version to be running.

    I've noticed a change in signal strength and weaker reception with frequent dropped calls at my home, for.. maybe 3-4 months... seems it used to be stronger with no signal issues.

    Just wondering if there's anything i can try with the handset, firmware that might be better...
    software that could be changed or whatever. Very odd, but nothing has changed with towers
    in my area according to Sprint.

    Have done Service Book push, Profile/PRL updates, battery pulls/recycle power etc. many times and no change.

    Thanks for any suggestions - if any -

    Mike

    The only thing to try is loading up older versions of the OS to see if any give you better reception.

    Certainly, with my 9900, different versions of the OS changed the signal strength I was receiving.

    Thanks, is there a quick and simple way to revert /replace the latest software and... anyone have this experience and know which version might be best for signal/reception vs. this latest version. ?

    geez - according to my searching so far it sure seems as if downgrading the OS is a big ordeal if you happen to only use a Mac DM - or has anything changed in the last few years i'm not seeing?

    You need to use a windows PC.

    There is no definitive answer to which OS will be best for you. All you can do is experiment with different versions.
