I have bought the phone at 2015 and my version of the phone is kitkat
there is a problem that is I can’t root my phone so it is a problem
and the camera quality is poor but battery life is unbeatable and there is
a bundle of hang to remove the hanging hera I found a solution
note the point s
un ninstall harm full apps
remove cached data
do not use more than 2 GB
give some space for phone
by doing this point s I am sure that your phone will not hang so iam congluding my words and thanks for reading
