Hi everyone, I'm a new user of this forum and I'm also a new custom ROM installer. I have a few days ago installed my first custom ROM on an old Samsung Galaxy S3. I also have an old Mediacom SmartPad S4 tablet, but I have not found any ROM for this tablet. Could you tell me if there is any ROM for this tablet or if you can install Windows 7 or Windows 10? At the moment the device is practically unusable. Mount an Android 4.2 and from what I know even WhatsApp will remove the availability for devices that have this operating system, since it has already removed it for those who have 4.1 (S3 mini for example). Could somebody help me out?
