Gionee M2 mobile is very heavy mobile but it is very tough to break and if your mobile fall down then it will withstand and you should not care about this.My all other mobile phone damaged due to fall down.And you can boost this phone by using inbuild process manager.App manager contain in its feature can boost the running speed and you can clear the running process and can easily run by using this kind of feature.I will suggest those people who have the same phone to clear the running process by app manager.
