The first problem relates to the Mi-Mover app, which allows you to transfer apps and some settings from any Android device (running 4.2 or higher) to a Xiaomi phone. This is a pretty common feature, even on Nexus and Pixel phones. However, if both devices are running MIUI, Mi-Mover will copy all system data to the new phone. This includes confidential information, like saved payment information, overriding Android's built-in sandbox protection in the process. Some applications are unaffected, like ones check the device or require a PIN at launch, but many popular apps like Twitter and Airbnb don't check the device. So if someone had access to a Xiaomi phone, they could copy all of a user's information without much effort.

Another flaw was found in how MIUI handles device-administrator apps. As you may know, many security/anti-theft apps (like Android Device Manager) can use Android's administrator permission to wipe the device. Uninstalling these apps usually requires the user's password, but eScan discovered that no prompt was given when deleting an administrator app. Theoretically, someone could steal a Xiaomi phone and quickly delete any anti-theft apps before the owner had the chance to use them.

Try charging with another brand charger. If the heating continues, you may have to service the mobile - because there's an alleged incident that RN4 got exploded.
Redmi Note 4 explodes, owner suffers serious injury; know what happened and reaction of Xiaomi

 

[TigerKing]

^why all mi phones heating up..
My Redmi note 4 temperature is fine, while charging and while watching x265 8 bit videos.

I think, it's all started during China border issue, who purchased mobiles after that incident.

Clap clap, for that analogy..

 

[nac]

What's the temperature you guys are getting?

I thought it's normal when charging. Redmi 4 goes upto 45 deg, that's the max I noticed when charging, video calling. BTW, lowest I got was around 35/36 deg when it was idle.

You maybe right! We should take this to Defense ministry.

Same here..

but some days back, other 2A 5V charger (I have Lenovo charger) take more than 4-5 hours to complete charge. And temperature also became high around 50+
So I started using OEM charger and its charging device fast. It takes 2 hours to complete charge.
I think, if you are using other than OEM charger, redmi device or some system app (in Installed apps) recognize which charger you are using and slows down charging..

hi everyone i want to post below query in Flipkart forum

can anyone tell me how to do it as it says you do not have sufficient previlidges

Recently i purchased RedMi Note 4 on Flipkart, on 15th May 2017, Order ID - OD109164671764760000,

First time i got defective product, Scratches on Charger surface and Speaker issues. So i contacted customer care and asked for refund they gave me replacement for it. But in repalcement also i got defective product only one speaker is working, camera issues and Brightness Issues, now i am asking them refund they are not giving.

If customer do not like product or get defective product customer can return it and get refund. as per their policy i am returing withing time period.

Instead of giving refund they are asking me to go to service center of MI and get issue solved, why the hell i should go i paid for new product not defective, give me my money back.

I want Refund. such a bad experience i got wasted my time and energy. i m regrating i purchased from flipkart. such a bad experience i got. I dont want your product. I WANT REFUND.

You made a wise choice. I've ordered both of these, Redmi Note 4 (4-64GB) for my wife, and Redmi 4 (3-32GB) for a workplace colleague.

Redmi Note 4 has a superior chipset, it can do slow motion video recording (720p@120 fps) and also 4K30fps (although with another software, not stock camera). I recommend using "OpenCamera" from Play Store for 4K.
With twice more pixels on the screen (1080p screen) and bigger screen too (5.5 inches), its a no branier.
Its good for 3D too. I just ran Asphalt 8 and its running at around 30 fps reliably. Not sure how the Redmi 4 would run it though.

And Audio quality tests also put Redmi Note 4 ahead, its in the league of iPhones. Loudspeaker is rated as "Very good". (source of info- gsmarena).

So, all the best.

Try new Google Camera..

Dolby Atmos is very simple to use while vipre is great for someone who knows how to configure it properly.
