Ominous display. Review on Nokia Lumia 720

My experience with this phone is around 6 months old. I bout this device on OLX and one of my friends saurabh was already using this phone since few months. I faced many problems with this phone but the major one was the strength of the display glass. I donno for sure which material they used to make that glass but me and saurabh has broken the glass 5 times wheres this never happened with any other phone by any of us. for my personal experience first time I got the phone dropped from the height of hardly 1 and half feet and I was expecting to receive minor or no dents but I was shocked to look at the screen coz it was scattered so badly. talking about other issues the phone has inbuilt AUTO-CLOSE feature for apps. be that an Skype or Facebook app or browser etc it will get closed(crashed) automatically after use of 10 to 15 mins and in some cases even 5 mins. plus the windows phone OS seems like developers have no interest in making app for that OS and plus the hardware restrictions of the phone and the app often make it a big troublemaker. Conclusion: buy this only if u r concerned a lot about privacy and security or if u r one of those who like nokia for no reason
