[G4 Q&A, Help & Troubleshooting] KingFatty:
Yes, look for the custom-made app from another member of this forum for the LG G4, it's called: Key Plus

You can assign other functions to the double-click of the volume up button.

Currently, double-clicking the volume down will launch the camera (and take a quick photo depending on your settings). Key Plus cannot change that action. But Key Plus can change the action for double-click of the volume up. You can choose all kinds of actions, but a lot of people choose the flashlight. Maybe you would want to choose google voice recognition, etc.

I got confused since i want to flash a rom to my locked bootloader H815ASEA my question is if something goes wrong can i flash back to the default firmware using lg flashtool?
[G4 Q&A, Help & Troubleshooting] glorifiedg:
Hi guys! Switch from nexus 5 to g4 5 days ago!

I have 3 problems that are really annoying me in G4.

1- can't find an option to save new contacts in Google contacts by default.

2- whenever I install WhatsApp I have duplicated numbers not in phone app but I do have them in SMS app (stock/yataa/handcent).

3- some contacts refuse to sync over bluetooth to my car. I tried to figure what's different between them and the ones who sync and can't find any common denominator.

Thanks!

Yes you can restore your firmware using the lg flash tool but how was you going to flash a rom without an unlocked bootloader?

[G4 Q&A, Help & Troubleshooting] Esxalon:
just found this, sorry if I'm wrong here

I got my lg g4 a week ago, love it so far, really love it, except one thing: The display is getting really, really warm. The back is not getting hot, just the Display, I understand that it can get warm when gaming, but the only thing I'm doing is listening to music and reading some PDF's, and after ~10 Minutes the display is gotten very, very hot. I don't know what to do, because I have only few days left to give it back and get my money back. I could also send it back and get a new g4 device, but if it's still getting that hot, then I'm stucked with this phone

In comparison, my old iPhone 4 was only getting this hot, when I use 3G, but the whole iPhone was getting hot, not just the display.

My Brother has a Samsung Galaxy S3 neo and he is playing games 24/7 and his device never got hot, maybe a little bit warm but not hot

my cousin has a lg g2, he said when playing games the back gets hot, but never, ever the display

Is my device broken or are all lg g4 (displays) like this? Battery is fine, I was nearly 10 hours away today and when back I had 24% left, but as I said it sometimes gets REALLY hot

if you guys tell me that's normal and my phone won't explode/break if I keep making the display 100000°C hot (CPU-Z is saying something about 60°C), I will keep my g4, because I have no idea what else to buy. Otherwise I will have to give my g4 back and wait for newer phones to come out.

Use a download manager like jdownloader or something similar from playstore..

---------- Post added at 07:22 PM ---------- Previous post was at 07:18 PM ----------

If you go in the settings and activate developer options look for allow oem unlock and tick that then go to lg developers website (on a pc or laptop) and follow the instructions to unlock your bootloader , once it's unlocked come back onto xda and follow the low effort root guide (step by step) it seems very daunting but don't worry because if you mess anything up then grab the lg flash tool and the kdz file for your phone and restore it back to stock...
[G4 Q&A, Help & Troubleshooting] jafferkhan:
Thanks for the reply... Is it imperative I follow the method you described or simply unlocking then recovery then root through flashing super su in the recovery?

There is a downloading progress and we can't do it anything. This is absurd and I think must be a method to control downloads without any program.

Hotword Detection over Bluetooth

I'm coming from a 2013 Moto X, so this is probably the issue with the phone that "hams my biscuits" the most. I'm using an h811, and I have Nova Launcher installed. I'm not rooted yet, but I got rid of as much of voicemate as I could. So I have finally gotten hotword detection from my lockscreen except when I'm connected to my car's bluetooth. I've tried toggling on and off the Bluetooth headset option in google now, and yet the phone remains unresponsive to "Ok Google" unless I unlock it and open Google Now at least once. It may seem minor, but the car is where handsfree operation is most important.

Does anyone have any tips on making hotword detection play nice with bluetooth?
