This piece has only 1 GB RAM with 1 Ghz processor. Camera is average but output is awesome when using Camera app downloaded from store. It doesn't lag while playing high emd game like Asphalt 8. Preinstalled Power Manager is awesome. Internal memory of 8GB is sufficient and can add upto 32 GB via expanding storage and phone still works good. 4000 MAH battery is awesome and can last approx 50 hrs without charging in heavy usage.
Phone starts lagging and overheating when a different company's charger is used and service is very poor.
It will be very tricky to find spare parts in market. Even authorized servoce centers would take more than 2 weeks to get the piece repaired if any part needs to be replaced.
