Very sturdy phone. Have fallen many times.. Cool.. gets into three pieces and when assembled works perfectly. Bought it four years back. Because no selfie had another one with the front camera. If you disable background services speed problem is ok. Can be used as a standby phone mainly for calling and messaging purposes. Can update the contacts from google accounts. works perfectly as an ordinary phone. Good voice clarity
It is a very very slow phone I ever seen.
From the day one, it is slow.
When making a call, I have to wait for couple of minutes before this mobile comes in the mood for making a call for me.
I can remember that day, when I had to make a call and I waited for 40 minutes to make this mobile agree to make a call for me.
I will suggest all to NOT buy this mobile at any situation because without having a mobile phone is far better than having this mobile phone.
the phone is good bt dhe worst disaster is hunging and loosing sensitivty.
On my 4th year of using this phone model, my greatest problem I've facing is that everytime I click the power off, it's always restarting so i always unpack the battery :(
I've been using this phone for more than 4 years.
For the people facing hanging problems, it is because of Google Play Services. If you have higher version than 9.0.4 of GPSer. you might face problem.
I too face the same problem when my play services are updated. Although having 9.0.4 version causes unable to use play store.
worst phone frequently hanging and battery life also very very very very poor.
