YU Yureka Plus Heating & Lagging

Hello,
I know it's Yureka's page but I couldn't found any separate page for Yureka Plus, hence posting the issue here. So, my issue is- my phone starts heating and also lags a lot on basic tasks. It's with most of Yureka Plus users, so my phone isn't faulty. I've not yet inserted any SIM card in it, so maybe, it'll heat even more whenever I insert SIM cards.

So, please help me to solve the issue. :(

Heating occurs in following situations-

• On using Camera for more than a minute (highest temperature of sensors keeps around 55C)


• On loading heavy website in Chrome (highest around 65C, yes it's too much)


• On doing basic tasks (around 50C)

Lagging occurs in-

• UC Mini and Facebook Lite apps, I can't understand why!


• In the multi-task bar (or whatever it's called), when I swap to close the app, it lag a little bit


• In Chrome while loading heavy sites (it's common in many phones, but still :P )


• On clicking on File Explorer icon, it takes around three seconds to show the files and folders.
