iPhone 4 signal field test

[nikolas410]

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.
