Hi Minniecat, I'm guessing that you know your device should be compatible? What device and OS is it?
Yes sorry I did mean which version of the Operating System in this case Android. Apologies for not being clear.
SuperSafe Boost is compatible with Android Operating System (OS) version 5.0.0 or higher number.
The Samsung Galaxy J1 was first introduced with the Android Operating System (OS) version 4.4.4 otherwise known as KitKat.
To add to the responses here, I feel it's worth checking to update the 'phone OS. Whether it will update depends on whether the supplier allowed updates - some supplier software may require a specific OS. But many Samsung J1 devices will update the OS at least to version 5 so here's hoping yours is one that will update.

Hi Minniecat, as Gondola says it is worth checking as you'll more than likely had quite a few updates since you got the phone.
