So last night, I noticed my phone was charging a little slow, as fast as 3% per hour, made me tensed. Upon checking some youtube today, a guy recommended to reset battery stats after diallinh *#*#9900# ,and my problem solved,this device is 3 months...
Nah, thats not what I asked, In my previous redmi phone, when I used to do whatsapp call, I will press power button and it will turn screen off, but it doesnt work with my Samsung
