Hi Sandeep,
Some of the highlighting design issues for Meizu M2 Note are
i) Uses 2nd sim slot as memory expansion slot
ii) Presence of screen protection is not surely confirmed.
iii) 1.3 Ghz clock cycle octacore processor
iv) Non removable battery
The last one is a real problem in case the handset hangs while using and there is no way out to resolve it except for just switching it off.
Although there are a few power and volume key combinations available to serve the purpose but they are not completely reliable.
