Almost 2 years back my sister wanted a cellphone so she came to me and asked what to buy so I search on web visited popular online stores and shorted out some models, after having a look of the models she liked this one after buying as every user does she installs apps of her will and used it after 2 months the apps tried to get upgrades which she is not allowing resulting the phone hangs, get stuck, work late, so she again came to me and as every sister or brother will do she blames me that it is a bad phone I cheated and so on. so I took the phone connected to my WiFi, it upgrades the phone fully after 4 hours all apps get upgraded then I used it for 24 hours roughly installed game of more than 1 GB and played that surfed internet watched videos watched steaming videos and it does hangs any time so I called her asked her about phone asked for upgrade or not she said yes it asked and she didn’t go for it I returned her phone told her to use it how ever she wants but update it when it needs. it has been more or less 2 years and she is still using without any complain.
