Yes, even the latest models of Poco phones may potentially encounter deadboot issues. A deadboot problem refers to a state where your phone is totally unresponsive and can't even boot up to the system. It is commonly caused by a severe firmware crash that may result from unsuccessful updates, firmware modification attempts, or sometimes due to hardware damage.
However, it's important to note that this does not mean every Poco phone will have this issue. It depends on various factors like the software's stability, the user's handling, and so forth. Also, the company is striving to fix such major issues with software updates. In case you ever encounter a deadboot issue, it's recommended to bring your phone to a professional technician or a service center as it might require a more technical handling like a firmware flash. Remember, attempting to fix it without proper knowledge might worsen the situation.
But overall, Poco phones are generally deemed as reliable and efficient smartphones. Just ensure that you always install updates only from trusted sources and take good care of your device to avoid such issues.
