Pehle apne phone ke settings me jao aur dekho ki koi unknown app to nahi hai jo battery zyada kha raha ho ya data use kar raha ho. Background apps check karo aur jo bhi app suspicious lage uska naam Google me search kar lo. Agar real hack ka shaq hai to factory reset sabse sure solution hai, lekin pehle apne Wi-Fi router history aur data usage bhi check kar lo.
