Me and my mom using Redmi Y2 but we don't feel unsafe because we handle all electronic devices with care and take all necessary precautions in all smartphones. I have many people don't take care for electronic devices and do not take the precautions. We can see in electronic devices many precautions are mentioned there(Do's and Don'ts) which may lead to damage to electronic devices and at last they can blast. We just feel unsafe if we hear any case of blast of a smartphone without knowing how that device was handled by that owner..
