Hello everyone I am a past user of Celkon A9+. I had buy it for 3500/- rupees. After using this phone for around 6month here is my experience.
The first problem I faced was its battery. It drains a lot, I have to charge it every 4 hour and after it gets 100% charge while I use sometimes it gets switch off and restart itself and shows connect to the charger. Its touch screen is not working properly, the apps opens automatically. This phone hangs a lot, sometimes I need to remove the battery and put again to hard reset the phone. While using internet it gets very heat as well. Overall I am very disappointed with this phone.
