    My S4 was not working so I opened the case as it was in power switch loop. Got it to work but when booted phone I was in pin screen lock but this was never enabled by myself. Why did this happen and how to get rid of it without doing a factory reset? The mob is second hand but it had a factory reset when I bought it. Is it possible the security pin from first owner was somehow still residing on the memory cache/memory??
