this has lineage os installed onto it. whenever you boot the device you need to press the power button to confirm it. this is because stock android/ Samsung's own system is extremely laggy and has a ton of issues. if you want me to put stock os on and remove all custom firmware please message me. SIM works on it and comes with charging cable and case. dispatched asap and any issues 1 week return policy and message me for more information on device. will be reset when you buy Also cleaned before dispatch
