Why my karbonn titanium 4g vista heat after turn on data. I bought it before 2 weeks. no background usage nothing overuse only watch YouTube or facebook
Hmm.. It's pretty normal for a phone to heat up while charging but only to a certain degree. Even calls make your phone heat up specially when Wi-Fi or mobile data is enabled. I'm sticking to my first answer, happened to me before what I did was uninstall some of the apps since some are rarely used or simply disable them.
No background apps. Its heat while charging. And after turning data on.
No data usage need to heat.
while calling it heatup.
Looks like a lot of your apps are running in the background and is using mobile data that's why your phone heats up. Try to uninstall them or freeze them and see the difference.
