Prevent Android Reset

Question

We carry out short-term rental on cell phones and tablets. You need a pill for a week, you can come to us, and we rent it too. What happens at the end of the week (or weeks) you need to return it. Often the tenant does not return it (for various reasons), but now it is stolen. We have an application that we download and can send a command to something that blocks the device. Or we can program the application to enable x-days, and then lock it (e.g. parking meter). After locking, a password is required to unlock. This works, but only works if the user has not yet returned the reset device to the factory. If we download the application and rent it to someone within 2 weeks (as an example), we find that often the tenant reset returns to the factory. For various reasons, they do this, mostly they play with him and just want to start all over again. Or, if their time has come, it is blocked, and then they pay for a different rental period, and we give them a password to unlock it. In this case, they now know that we have a rental meter.

We can connect the device and install the application as a system application, but chasing empty tools and playing a cat and mouse game with vendors trying to prevent rooting is too much work.

What do I need, is there a way to set a password in factory reset in Android settings? I understand that most MFG devices allow you to press buttons and reset, but with which I can live. I need to not have a reset button in Android settings so easy to execute. Does anyone have a way to do this?

Answer 1

As I see, since tablets like Android phones have both a unique identifier and imei (phones), Google gets an imei phone, you can see that they register this. So far, they have not tracked the device after a hard reset, so you have nothing to do. Cloud policy change is the real solution to this problem. Imagine if larger providers, such as facebook and google, etc., can ask for authorization when a user reports about the lost or stolen to the original owner, this problem will not exist.

Answer 2

What you may need if you rent for specific software is a kiosk mode app. This can be achieved easily if you plan the program schedule for 2 or 3 seconds in the future, when it will be killed. In addition, modding the OS will not be easy.

Answer 3

Have you tried to save application data on an SD card?

This store is not deleted unless you perform a cleanup.
