Says and knows anyone who has a properly working device after 3 years. My Note 2 would have been working still fine after 5 years if it wasn't accidentally water damaged 2mos ago. The S3 that my brother bought alongside it is still working and my mom is using that. The first tablet we had at home was a Samsung P6500 Tab Plus. My mom is still using it to play games like Sim City and Candy Crush. I check it up every now and then and it's far from crippled.
Exactly. We still have Nexus 7's, a SHIELD tablet, OG Moto X's, etc. that my daughters still use daily. There isn't a hard expiration date, it's all about taking care of it.
