Samsung the tech giant has recently launched its Z series in which the Samsung Galaxy Z1 has a very good speakers and has a amoled display which is crystal clear display.Actually the most cracking about the phone is it does not run on android os( operating system) but it runs on TIZEN OS it is a new os from samsung itself.It doesn’t support the android apps or the apk files.Its camera is brilliant.Though its battery backup is weak.It is not durable because it has only 768MB ram and 4GB rom( internal memory or phone memory) in it. It does no has that much value of money which was expected from samsung
