Anonymous, 17 Oct 2016Hai friends i want to buy k4 note.is it good.please tell meYa its work well i m satisfied with the product
ARUL , 19 Oct 2016i have purchase lenovo k4 note ? dnt buy crappy laggy lenovo phones..
My name is Lokesh Kumar Sharma Pls k4 support the volte support or not
K4 note battery and overheating problems are easily solved with 3 steps:
1. Go to Settings>Power manager>Background app management>click "Restrict All"
2. Install GREENIFY (Oasis Feng), go to Settings then check "Alternative Screen mode", analyze then greenify all the apps that can be greenified. (Note Android Marshmallow has a greenify clone called "doze" but the current K4 note Marshmallow is full of bugs so do not update yet!)
3. Install CPU Cooler Master by PICOO Design and follow installation directions. This will solve overheating problems.
4. Install AMPERE by Braintapp. If you use a 2 ampere (2000 ma) or higher charger and a good cable, you should read between 1800 to 2000 ma. If less than this, replace your cable. The K4 Note can give you 7 hours talk time with just 30 minutes of charging.
A VINOD, 19 Oct 2016please tell me jio sim is working on this phone with calling alsoIm using K4 with Jio sim. You can only use data with Jio sim. Calling not supported as K4 doesnt has VoLTE. You can use Jio voice or simply whatsapp for calling.
Awesome device. Im totally satisfied using K4 Note.
Only one thing is not good which is its camera.
