[Xiaomi Mi 4C] twister7373:
Hi guys,

This is my first post, i'm new to XDA and a noob in Android. I work as software developer in argentina, so i understand concepts like hardware, processor, firmware, OS and so on, but i have no experience of any kind in android developing or modding, i have never flashed a rom. I'm here to learn and contribute if i can.

I have bought a Xiaomi mi 4c for my daughter, and from then started reading a lot about custom roms and android OS. Mi4c came with lte bands 1,3,7 enabled and nothing more, and in my country lte bands 4 and 28 are used. i knew this before i bought the phone and its not a problem cause we are almost always connected to wifi. I think mi4c is a great phone, fast processor and full of features.

At this moment i have read a lot about unlocking LTE bands, specially about modifying NV values (6828, 6829, etc) and found that almost nobody could succesfuly unlock bands. as far as i can understand, its not enough to enable a particular band by modifying NV values, the modem firmware needs to know how to handle that band prior to use it. That kind of information its not located in the andoird rom itself, and thats why installing different custom or stock roms doesn't effectively enable extra bands. That information is located in the modem firmware (modem.bin, non-hlos.bin) and that code its not open source, its held protected by qualcomm.

So i have found another phone with the same SoC as mi4c that comes with more lte bands enabled from stock. im talking about Nextbit Robin phone, wich has this bands enab led from stock condition:

GSM 850/900/1800/1900

HSPA 850/900/1700/1800/1900/2100

LTE Bands 1/2/3/4/5/7/8/12/17/19/20/28

I wonder if could be possible to enable the same bands in mi4c just by flashing the robin modem files into mi4cs. is there any chance of success? does anybody tried to?

i know it was a very long post, sorry for that, i just wanted to introduce my self. i ll write shortly next time :)
[Xiaomi Mi 4C] Phlogistol:
Welcome to the forum :)

Short answer -- you can't enable any more LTE bands. Some people claim they enabled software support in the modem driver, but the problem is hardware; Xiaomi disabled all unsupported LTE bands on the antenna and they do this on almost all of their models. Sorry :(
[Xiaomi Mi 4C] kazukirein:
So, by hard modding the antenna (which require hardware skill), is it possible to unlock more LTE bands? This phone have very good price/performace, so if there any trick, mod, rom to improve it, than why not?:)
[Xiaomi Mi 4C] Phlogistol:
I guess it should be technically possible, but good luck finding someone who knows how to do this :)

Does the LG G4 support carrier aggregation on T-Mobile? My phone is not displaying it in Engineering Mode. Should I try a factory reset to fix any problems, or is this normal?

Does the 6p have the double tap to wake option?
[Nexus 6P Q&A, Help & Troubleshooting] richie.slayer:
Nope, had seen a video where the presenter absently tried to double tap it, didnt wake up.

Though with ambient display I kinda see why they omitted it.

With the inclusion of the sensor hub hopefully the battery hit stays frugal.
[Nexus 6P Q&A, Help & Troubleshooting] jagman96:
Shouldn't matter with the fingerprint scanner. You shouldn't even see the lock screen.
[Nexus 6P Q&A, Help & Troubleshooting] ericerk:
That honestly bums me out, hopefully there'll be a third party app that enables it, I love that feature. I know it's enabled on the Nexus 9, as a Display option, I hope it was disabled.

Not going to lie, I don't plan to use the finger print scanner, I really don't love the though of it being in any form of "confidential / private" (encrypted) keychain.
[Nexus 6P Q&A, Help & Troubleshooting] frigidazzi:
I hope this can be enabled without using lots of extra battery like it does on the nexus 5. I use a wear watch so the lock screen is off much of the time anyways, so double tapping while the phone is still on my desk would be great. Personally I was not a fan of the ambient display on the nexus 6. So I am sure I will disable that right away.
[Nexus 6P Q&A, Help & Troubleshooting] mazinya:
Will I be able to wake up phone with voice command when screen is locked and and off?
[Nexus 6P Q&A, Help & Troubleshooting] Poke_N_PDA:
On the moto x, ambient display was awesome and the was never a need for this. On the nexus 6, it just never worked right. I'm hoping sensor hub resolves this and makes it perfect. Combined with the fingerprint scanner I really have no desire for double trap to wake. However, I don't fault others for wanting it. Hey, they threw the LED in there when it was disabled by default, maybe dttw is in there too.
[Nexus 6P Q&A, Help & Troubleshooting] chakra:
Plus they claim they own your fingerprints once you enter them, that is scarry.
[Nexus 6P Q&A, Help & Troubleshooting] krazyq:
fingerprint unlock doesn't work well if you use your phone while it's on a desk so Double Tap to wake should be a must on almost all new devices.

Moto X's Display Notification is probably one of the best things out there, I'm definitely going to miss it

[Nexus 6P Q&A, Help & Troubleshooting] MasK:
Well..like someone mentioned, if the phone is lying on the desk, there is no better way to wake it up other than to press the front button (Samsungs) or double tap it.

This ambient display.. how does it work? You wave your hand over it and it shows your lock screen or more?

I do not use any lock screens. How is this gonna help me?

Cheers.

Hey, I was just as skeptical as the next guy, which is why I agreed it sounded scary but needed proof before I went off believing it. Don't lump me in with the gullible.
[Nexus 6P Q&A, Help & Troubleshooting] 640k:
wut? sensors detect when they're covered, meaning ambient doesn't turn on while in your pocket. if you're just driving around, it'll show, unless your phone is face down.
[Nexus 6P Q&A, Help & Troubleshooting] CacheOnlyPlease:
When the phone notices movement (like when you take it out of your pocket), it will wake up the screen partially (only the pixels it needs to with an amoled display) to display your notifications. Like others have said, when the prox sensor is tripped (ie: when the phone is in your pocket) it's disabled, but it is quite annoying to see your phone light up when you're driving because it senses the bumps in the road as movement and wakes up the display.

It's a gimmick if you ask me. Cool that it's there, but I definitely appreciate that you can turn it off.

Edit: To contribute to the thread, I'm sure there will be a kernel out there that supports double tap to wake. I understand not everyone roots their phones, but I have a feeling a majority of nexus owners on this forum will.
[Nexus 6P Q&A, Help & Troubleshooting] unknown1205:
ok, i often have my phone on my lap while i drive so i just assumed it would be on in my pocket as well. still i dont prefer to have my screen constantly turning on with the slightest movement. cause sometimes i would be carrying the phone in my hand, etc.
[Nexus 6P Q&A, Help & Troubleshooting] FuMMoD:
Looking forward to a custom kernel that enables DT2W without draining battery. Really loving this feature on my Oneplus One.
[Nexus 6P Q&A, Help & Troubleshooting] 640k:
i never had any problems with the ambient display randomly waking my phone (unlock, butt dial, etc). the only time i've ever had problems is with the shake to camera. handy when you need it, but a huge PITA when you don't.
[Nexus 6P Q&A, Help & Troubleshooting] Bokoblin:
Do you think an app that does the same thing as this one for the nexus 6 on lollipop : http://www.androidauthority.com/double-tap-nexus-6-root-app-569624/ can activate it ?

Was it working good on Nexus 6 ?
[Nexus 6P Q&A, Help & Troubleshooting] sprintrjm:

Self Incrimination: Password vs Fingerprint

The number one issue I have with fingerprint is this. Supposedly giving up your password is self incriminating and you don't have to but if your phone is locked with your fingerprint you have to unlock it. Hence for this reason Ive been hesitant to use it. Seems to break a chain of security you might have. I guess im just paranoid.

Oh thanks, couldn't you just navigate to the folder using a root explorer and change the 0 to a 1? I could be way off but id think it would be worth a shot. So I hope a dev makes this enabled on a rom and allow sRBG to not get reset on reboot.

[Nexus 6P Q&A, Help & Troubleshooting] fredphoesh:

What???

the fingerprint scanner is UNDER the phone. The screen is on TOP of the phone...

if the phone is on my desk, as it is 80% of the day, then how does double tap to wake not matter?

I've had the phone for a day, and it is a hassle to turn it on. My note 4 has a physical button to wake on top... so it is a feature I'd like A LOT.

[Nexus 6P Q&A, Help & Troubleshooting] NCguy:
Coming from the oneplus one I really got used to double tap myself. I'm not rooted so I've settled for wave or depocket to wake on the 6p and I use the proximity and gravity sensors to keep the screen on while I'm holding it and allow it to screen off when I set it down on a table, in my pocket, or in the case. I'm getting adjusted faster than I thought. The sensors seem to use no significant amount of battery at all.

[Sprint HTC One (M8)] F0rZ3r0:
I have S-ON and a non-HK phone with an OS of 2.16.651 I believe. [MENTION=4609217]Sloth[/MENTION] tried to help me but to no success, so I'll try to see if anybody else can help me figure out the issue.

Basically, everything works up until I actually start to flash the phone. It gives me this error:

FAILED (data transfer failure (Unknown error))

There's a bit more to it, but that's mostly unrelated stuff (the command and blahblahblah).

I've tried 2 different computers and different ports on all of them. I don't have any other USB cables for my phone available, but this one works with my PS4 controllers finely so I'm guessing it should work fine.

If someone could help me and anyone else with my luck in the future, please answer. I don't want to have to resort to a store as I have no money and the store is quite far. Thanks!

EDIT: Something else to mention, there is no firmware on this device and only has an accessible bootloader and recovery. I currently have the bootlocker relocked. I had ViperOneM8, although uninstalled after realizing I had no access to WiFi (I ignored the disclaimer :c). I don't have a SIM card as this phone was given and I didn't buy it myself from any carrier, I have no service. Some other stuff to mention is that I verified the MD5 of the firmware and it was not corrupt, I had the proper working drivers as I checked if it found my device, and that's it.

I had the same problem, especially when I used VR goggles to play PC games(via Trinus VR app) even when USB was plugged in, after 30min of playing eg doom 3 i had drop from 70% to 40%

In normal usage, when I was watching movies and using standard Sony charger I had slower drops but still after one movie I had drop from 80% to 75% with charger plugged in...

I found only one solution for that: 2.2 A charger and 5.2V

Its damn hard to find such charger, most of them have 2 USB slots and cut half this power to every USB, but some of them give full 2.2/5,2 to every USB slot and that one is best.

BUT problem is, that such charger can really quickly mess up your battery. Phone is hot as hell, and battery can die x2 faster than using normal charger. So I use it only sometimes when watching movies.

PS also I found out that using docking station that use pins are way better and faster to charge our XZ.
