Application helps to comprehensively check old Android smartphones and iPhones

Buying a used smartphone is quite difficult, even for those who are tech-savvy. It will be difficult to check all the features and components inside the device with the naked eye. Therefore, if you are not sure about the quality of the device, you can immediately install the Phone Doctor Plus application for Android or iOS.

The interface of Phone Doctor Plus is relatively simple, providing up to 30 different features, allowing users to comprehensively check everything from hardware, features to sensors on the smartphone.

The first section will display general information on the smartphone including battery capacity, storage capacity in the device and memory card, RAM, CPU, download/upload capacity...

To check other features on the smartphone, users just need to switch to the next page. This includes items to check multi-touch, touch screen, speaker and microphone... In addition, you can also check Wi-Fi, 3G, Bluetooth, location, and vibration connections on the smartphone through the options below.

If any part is passed, it will be marked with a green check mark, otherwise it will be marked with a red check mark. If you see too many unstable features or components, think again before bringing that smartphone home.
