I own a 32GB, 3GB RAM version of Moto G4 plus. It’s becoming very hot when I use apps like camera/torch which are basic applications of a smartphone. Even it reached as high as 45 degree Celcius while using these apps.
Also while charging using the Turbocharger, you’ll get afraid that the phone is going to blown off, the temperature increases very fast & stabilises around 44 degree Celcius for some time & then gradually reduces to normal temperature after battery % increases above 70. Also, the fingerprint sensor/phone doesn’t recognize any of the fingerprints for some fraction of time even after multiple attempts.
