[Android Q&A, Help & Troubleshooting] onenessboy:
Is Carrier Jio from india ? if yes they say that 1800 Band 3 support.

Oh even after rooting its not supporting :( so that means its not permission issue. My sim working well on another volte enabled phone perfectly.

by the way how did you root ? I tried different rooting softwares none worked.

That means ulefone wrongly said Volte will work for this phone. I just bought this as it said support volte...

If phone is volte enabled, then why it is not fixing to on.. a million dollar question :(

I heard in may forums people say VOLTE is a software feature than Hardware feature, however seller said Hardwareneeds to be upgraded. so bad.. ulefone in their website in specification they said, volte will work .. However in reality its not
[Android Q&A, Help & Troubleshooting] Darkrevange:
No...is Orange Romania, On a Xiaomi redmi note4 volte work's prefectly...

Probably is a software problem...Perhaps something must be changed in build.prop

For root I followed the tutorial on page two of this thread and it worked...
[Android Q&A, Help & Troubleshooting] rob1992:
I may have found reason. It might be that a phone model needs to be certified on a network before it can use volte, maybe the power isn't yet? I'm sending an email to our national branch of T-Mobile today.

Update : they don't seem to be that willing to allow unlocked phones on their network. They prefer that you buy a phone supplied by them so they can extort you for money. They even have gone as far as requesting oems to remove support for band 12

[Android Q&A, Help & Troubleshooting] onenessboy:
so bad, the same thing here...worst carriers insisting to buy their own branded phones...

Oh my god, Carrier blames phone, while ulefone mailed me that carrier is problem. What the hell happening, its a lesson for me, always to go for branded phones... they are selling this phone like first ever 6000 + mah battery but in reality, volte is not functioning..

When i contact ulefone, they said that it should support 1800 Band 3, when I contacted carrier, they said phone needs software update. ....

does some expert knows how to crack this and enable volte ? as most of people use custom roms to remove all restrictions by these carriers and oem companies ?

Please help guyz

so sorry to hear this.. i too wasted my money on this crap , Just for volte support i bought this phone as it has huge battery backup... :( raised a disupute with seller but they closed it saying reason carrier is the problem.

badly need some expert to crack this phone to make volte working...waiting...waiting...waiting...
[Android Q&A, Help & Troubleshooting] Darkrevange:
It's a software issue ... Because Orange does not sell xiaomi phones and on redmi note 4 it works...

I looked in build.prop and there is no setting for volte and ims ... So I do not know how ulefone say that should work when there is no trace of volte or LTE 4G CALLS in settings

can you check these...

Hey friend,

As you have root permission.. can you check if following files exist. Because one of the forum they said, following method to enable it.'

Can you check if below works for you

Install SQLite App & launch this app. Go to files tab. Tap on data > data > com.android providers.settings > databases. open Settings.db , Global , search for Volte_feature_disabled change value from 1 to 0 close sqlite editor , restart your phone

.

Can you check these

thats good news then... do you see Volte_feature_disabled like that ? I dont see that in your thumbnail, can you check if this is there

and volte_vt_enabled also should be 0 ...can you try

see below post for universal method for enabling volte.. see section 2 --this may not specific to this phone ..u can try it

https://www.bigtricks.in/how-to-enable-volte-feature-in-any-android-device/

check that method and try if that can enable volte

Another note about volte, I guess ulefone was of the opinion that the phone supporting the required bands == being able to use a technology that the provider has to decide if it's enabled or not on a device to device basis. I HIGHLY doubt we'll ever see providers enabling it on this model

Hi,

did you get a chance to verify this ? Just curious to know if this helps
[Android Q&A, Help & Troubleshooting] Darkrevange:
Hi. It doesn't work...
[Android Q&A, Help & Troubleshooting] onenessboy:
Oh... so sad to hear...so ulephone selling all all false information that it supports volte...too bad.
[Android Q&A, Help & Troubleshooting] rob1992:
Well technically it does support it, but VoLTE is a certification based service. If your phone company says no you can't use it. It mostly comes down to laws like the phone also needing to be able to support E911 to make sure you can always call the emergency services.

What Ulefone does is tell us that the certification stuff is all in the hands of the provider and all they need to do is making able to use band 12.

It's a bit more involved than that.

update:

So i've been using it for a couple of weeks. After having the glass screen protector on for a while i took it back off both because it had cracked and because it pretty much starts radiating blue light when it's outside in the sun. I'm just going accept micro scratches from pocket sand. I get about 2 days from a full battery including leaving it on during the night. Something i did notice is that when you have both gps and bluetooth on it will get quite warm to the touch on the back. Most likely this is just a side effect of metal conducting heat a lot better as plastic.

Initially i thought that the audio chip was distorting a lot but after some more looking in to it i found that i indeed have way more songs on my phone that have succumbed to the loudness war. It also gets fairly warm while charging, so probably not the best power conversion circuitry in there.

[Android Q&A, Help & Troubleshooting] bialyikar:
Testing on Linux

After downloading the OTA update, the phone rebooted and then he booted in TWRP. The reboot of the system results in a return to TWRP. The solution is to install the original Recovery.

Download rom (np. Ulefone-Power-2_Android-7.0_20170427.zip)> unzip> in the unzipped directory open the terminal and issue the command: sudo fastboot flash recovery recovery && sudo fastboot reboot

The phone will bootin and update the system.

Then you can restore TWRP and SuperSU :)

[Android Q&A, Help & Troubleshooting] Paradise12314:
So if I'm fully understanding this Thread, there are 2 versions of TWRP. One works but without Touch, and another has Touch but has difficulty with Nougat Encryption. Just a few questions:

Does the non-touch TWRP work every time? Or can you only launch it once then it goes wonky after?

When you was porting the non-touch, which partition did you take the Kernel zimage from the Power 2 Rom? The Recovery or Boot? Perhaps they are both compiled differently. Touch Enabled/Disabled etc.

I've found TWRP for an Oukitel U11 Plus. Can someone try porting that one to see if Touch and Encrypted Mounting can work together? Maybe we will be lucky with it :) Attached zip file!

I don't have the Power 2 myself, but hopefully I'm getting it for Christmas time. Once I do, I'll give it a crack. I'm not bad at tinkering myself. The more people to attempt porting the better. Shame we can't get Ulefone to Cooperate with us.

Factory Reset not allowing me to chose option

Hi All,

Anyone having an issue after entering the hard factory reset option screen (holding Power and UpVol) that you can move among the 3 choices but cant select them :rolleyes:

Also have Win10 and cant seem to Format + Download with the Smartphone Flash Tools. Think this is because the Ports VCOM devices Mgr option doesn't stick around after powering the device only have a MTP drives not an MTK (may be wrong)

Can anyone help. All this becase I lost my access pattern and want to reset everything.

A
[Android Q&A, Help & Troubleshooting] bialyikar:
A bit late, but maybe still useful.

"holding Power and UpVol" isn't "hard factory reset" option ;) Anyway, when you entering the "Power + UpVol" menu, you navigate witch "VolUp" and accept witch "VolDown".

If You hawe to format / bring back the factory software, follow the instructions:

-Download Power 2 - ROM

- Unpack FlashTools, and Click on Flash_tool.exe

- Select "scatter-Loading" and search MT6750_Android_scatter.txt in ROM

- Wait file to be added into Flash Tool

- Select "Download Only" or if upgrade "Firmware upgrade"

- Turn off your phone, remove the battery (if the battery is removable) and replace it after some seconds (and don't turn on the phone).

- Press “Download” button to start

- and connect your phone into the computer via USB data cable.

- The process will start and a red progress bar will appear after color purple, yellow.

- And green circles display

- Finish !

- You can now safely disconnect your phone and turn it on.
