WHAT COULD CAUSE AN ANDROID PHONE’S WIFI / BLUETOOTH TO BE UNABLE TO COME ON?

Common causes of this issue include:

• Corrupted apks or files: The WiFi / Bluetooth apks or files might be missing or corrupted
• Third-party apps: Third-party or WiFi / Bluetooth management apps might be interfering e.g Babel Fonts apk
• Temporary OS error: The Android OS might have encountered a minor error
• Connection timeout: If no Bluetooth / WiFi network is detected within the set timeout (which might have been set too low in this case) then the WiFi / Bluetooth will automatically go off
• Hardware: The IC might be damaged

HOW DO I DIAGNOSE IF MY WIFI AND BLUETOOTH NOT COMING ON IS DUE TO A SOFTWARE OR HARDWARE PROBLEM?

You only need to run a simple test by trying to turn on your phone’s FM Radio. If the FM Radio can come on then its most likely a software issue. If the FM Radio can’t turn on also or force closes then you’re most likely dealing with a hardware issue.

To confirm its a hardware issue, try changing the phone’s font manager i.e Babel fonts apk sometimes cause Bluetooth and WiFi not to come on.
