Had this old phone lying around. I thought I re-purpose it for some IoT stuff. It an old Micromax A50 Ninja (running ginger bread 2.3.6). I want to make an app on this device that communicates with arduino. However, I cannot sign into the device. I re-checked with my credentials else where, and they checkout to be fine. But on this device, the sign-in still fails.
Is this because the OS is outdated? Well, can I do anything on this phone, now that this is the state of the device os?
