    Hello everyone.

    I opened the signal field test. app today on my iPhone 4 by dialling *3001#12345#*.

    After quitting the app, by pressing the home button once, there were DB's showing instead of signal bars.

    I tried doing a hard reset (home+power button) and it didn't fix my problem.

    Does anybody know how to change the dbs back to signal bars because its better for me to understand?

    Thanks in advance :)

    Same.
    Restart your iPhone, failing that, try doing a restore from backup - fixes most things.
