One warning for galexy a7 users please don’t upgrade your firmware to lollipop because kitkat is the best one, If you upgrade to lollipop need to face the CPU lagging issue and battery drain fast,
so please don’t do it. .
I upgraded my phone to lollipop after that I faced many problems like battery drain issue, slow performance etc. after that I again downgrade my phone to kitkat 4.4.4 with the help of odin 3.
So please don’t do it. .
