Hi friends, Today I am telling you about the Samsung Z3 smartphone which is not good.This phone is based on Tizon OS which is not good OS compare than Android because it has not much useful apps at Tizon Store which is use in android phone.I have this phone but I am not satisfy from its features.Its Hardware features almost good but should be 16 GB inbuilt memory in this phone because 8 GB memory is less.User can use only 2-3 GB for data storage and remains memory take applications after install.So due to less memory it shows notification of Space running out.Its front and rear camera quality is good but battery backup not much better.Display resolution is good but it has main disadvantage it has less useful app at Tizon store and we can not easily install applications.Its good looking phone and stylish design but fetures are bad. Its only 3G support not 4G support.Its features are complecated.Difficulty to understand its features to the user.Sound quality not good.Its expensive smartphone according its features.Its not value for money.Now I want to selling my phone.I gives only two star.Thank you.
