Phones & Connectivity
Bluetooth Range and Dropout Checker
Work through a repeatable placement check for a connected Bluetooth accessory. Use distance, obstacles and observed behaviour to choose the next comparison. The page does not scan devices or calculate a maximum range.
4G and 5G Signal Reading Checker
Understand a signal value copied from your phone or modem’s own status display. Select 4G LTE or a 5G SS metric, then enter the reading manually. The browser cannot read the cellular radio or verify the source.
CarPlay Connection Troubleshooter
Choose the connection method and the requirements already checked for this iPhone and vehicle. The guide gives manual next steps for CarPlay. It does not connect to the car, inspect the cable or confirm compatibility from a model database.
Screen Mirroring Compatibility Checker
Select the source platform, the receiver’s protocol and the symptom observed. The guide distinguishes AirPlay, Miracast and Google Cast before suggesting checks. It cannot discover displays, read device capabilities or certify a phone and TV combination.
Phone Sound Checker
Choose the phone platform, affected sound, observed output and Focus or Do Not Disturb state. The guide separates incoming-call ringing, Clock alarms and media before suggesting manual settings checks. It cannot read a silent switch, volume, audio route or alarm configuration.
iPhone Message Colours Explained
Check the meaning of an observed message color and service label in Apple’s Messages app. Select outgoing blue, outgoing green, incoming gray or unknown, then the visible label and symptom. No conversation text, contact details or screenshots are needed.
