I'm pretty sure now it must be a faulty battery. I can charge to 100% and it lasts fine if I only use the phone for calls and texts. When I do anything online, browsing, Facebook or use any app that updates online it now crashes withing 5-10 minutes. I just went from 98% to dying in less than 5 minutes. It then charges back to 100% quite quickly, in less than an hour. New battery on order now, hopefully that will sort it.
[Device Reviews and Information] soulfunkdjx:
The same happened to me and I was keep calibrating the battery in every charge. in the 4th charge the battery it was working good again. Maybe you must insist.
[Device Reviews and Information] handful17:
It was the battery that was knackered, I noticed when I took it out the other day that it's suffered the expansion mentioned elsewhere in the thread (I think on this thread, I know I've read about it somewhere) The middle section feels distinctly "fat".

Anyway, I now have a new battery(+ a spare) and all is fine again. For the benefit of others I bought my batteries from Vifocal http://vifocal.com/catalogsearch/result/index/?cat=11&q=be+touch+2+battery They came from China in 18 days.

Thanks to all who suggested solutions!
[Device Reviews and Information] soulfunkdjx:
OK guys here is a solution to your problems with the ulefone's be touch 2 battery. You need to calibrate your battery but with specific procedure. I did these steps and I have seen a huge difference.I did this with the official rom but I don't think you'll have any problems with other ROMs. Let's start....

01)Root your phone.

02)Download from play store the application Battery calibration by Nèma (the one that I used and worked for me)

03) Now use your phone until the battery dies. After 5 minutes open again your phone and use your phone until it dies again. Do this procedure as many times it takes so the phone can't switched on. Remember every time the phone is powering off you need to wait 5 minutes the most to switched it on again.

04)Now that your phone is fully dead remove the battery for 10 minutes and then insert it again. Now power it on. If is not starting continue to the step 5. If is starting just repeat the step 3 procedure again until is fully dead.

05) Now as your phone is fully dead just plug the USB cable to start charging but leave the phone as it is, don't power it on. Wait till is says 100%.

06) Now that you are 100% (don't believe wait is says ;) ) don't power it on and remove the battery for 10 minutes. After 10 minutes passed insert the battery and power on the phone. Voilà... I suppose that is not showing 100% huh?

07) Now open the application battery calibration and make green the two buttons and plug the USB cable to charge until it sounds a strange sound that notify you that the battery is fully charged. Unplug the USB cable and power off your phone. Remove again the battery for 10 minutes. After 10 minutes passed insert the battery and power on the phone. If is not showing 100% repeat the step 7 until you'll get 100%. If you get 100% go to step 8.

08) As your phone is powered on open the application battery calibration and make green the two buttons. Plug the USB cable and if it says the the phone is fully charged press the button "Battery Calibration" and remove the USB cable. If is not showing you a message about your phone that is fully charged wait till it sounds the strange sound that is notify you about fully charged battery and then press the button "Battery Calibration" and remove the USB cable.

09) Now use your phone normally and when the battery reach the 0% and your phone is powered off go and plug the USB cable (You'll see a new icon with a green battery and a thunder), don't power on your phone and let it charge to 100% without any interactions.

10) Repeat the step 9 for 3 - 4 times.

Congratulations, now your battery is fully calibrated.

Same thing happened to me today. Suddenly the battery charge dropped during phone conversation from 85% to 15%. After I plugged the phone into car charger the battery started to heat up and there was a burnt smell, like burning hair. The battery is slightly fatter from the middle. Now it's plugged into wall charger and everything seems "normal". Of course I ordered 2 new batteries from Vifocal like you. Hope they come soon. It feels a bit uncomfortable to use possibly dysfunctional battery.
[Device Reviews and Information] handful17:
Mine never smelt strange and held battery fine for calls but as soon as I did anything that involved data/wifi it dropped like a stone. It's fine now with the new battery and it's nice to have a spare as well! You can track the delivery from Vifocal to some extent on 17track although mine stayed on "preadvised" for quite a long time and then went very quickly to "in country of destination". Hope a new battery solves your issue as well.
[Device Reviews and Information] imprezawrxhatch:
Okay, I have heard many others that their battery became bloated. The thought didn't cross my mind that I would be a victim as well. :(

It even force the display to pop.

See the battery.

I need step by step info how to flash CM12.1 from Needrom into my Be Touch 2 please.

Should I go like this?

1. Install TWRP with Flash Tools

2. Root with TWRP and SuperSU

3. Install CM12.1 with TWRP

4. Install Gapps with TWRP

I have Windows 10. Should I install some MTK drivers first?
[Device Reviews and Information] soulfunkdjx:
Before you do anything go to your phone settings and enable the usb debugging from the developers options.

You need to install these drivers.Try to see if it works. If it not then someone with windows 10 should tell you how to do it on windows 10.
[Device Reviews and Information] Moolok:
Ok. I did all this and now my BT2 has TWRP, root access and CM12.1. Should have done this ages ago. Feels like a new phone again. And no more stagefright vulnerability.

I managed to install drivers into Windows 10 and after that flashing TWRP was no biggie.
[Device Reviews and Information] tareumlaneuchie:
Farewell... So I changed the Screen on my BeTouch 2 - which was provided by the reseller when I indicated that I was seeing white spots.

The screen change is not so difficult to make, even though the screen is glued to the frame. It take a bit of force to separate the LCD screen from its frame, but with the right tools it can be done (metallic and plastic spludger tool). Once the screen is removed, you will need to remove all traces of glue from the frame. I used 3M black double sided tape specially made for iPads and the likes that I go from Amazon to close it all up.

Unfortunately, the replacement screen I have is bad (I see white / blurry bands and no discernable images) ... This is the last straw for me concerning Ulefone. The phone went to a drawer and will most likely end up being destroyed, as I can't even wipe it properly. I went ahead and got an old S4, which I find to be sooooo much better than the BT2.

A day typically ends around 40% battery, with no fear of a sudden discharge. Good luck to you all with this crappy phone, but this has been a serious waste of my time and patience. I am done with 'no-brand' china phone.

Screen turning black - problem during a call and not coming back until the call is finished:

Playing around, I found out, that if I do the calibration of the proximity sensor the other way round - cover the sensor, when it tells you not to and leave it uncovered when it should be covered - calibration succeeds and behavior while calling is correct again.
[Device Reviews and Information] Moolok:
Also flashing and replacing the stock ROM with CM12.1 fixed that bug. Among others like auto launching an app after install/update.

I hope I get that new battery soon. Current battery seems to be getting worse. And fatter.

128GB microSD card compatibility!

I'm glad to tell you that our phone is compatible with 128GB microSD card!!! ;)

Tested personally one from Team Group. I'm talking about this one.

Here are some screenshots...

Is this the solution for installing drivers on Windows 10 64-bit or something else?

http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/
[Device Reviews and Information] Moolok:
Actually if I remember right I just installed drivers as legacy device or something like that. I had no need for that a complicated measures.

Hmm... Now I'm thinking updating my 64gb sd-card to 128gb :D
[Device Reviews and Information] corduroy27:
Well... if someone can be more specific about Windows 10 64-bit driver installation, it would be nice...

Because I had bad experience from a wrong driver installation in the past.

Only Keep in mind that I'm sure only about this (Team) card. I don't know if other 128GB cards are compatible too. Maybe yes, maybe not.
[Device Reviews and Information] peterscm:
After new battery arrived and charged, I cannot power on my phone. Pressing power button does nothing..

eventually I manage to turn it on but I don't know how I did it. After the phone is powered on, the power button and volume button is not working. No matter how hard I press it, it does not power off. The volume does not increase or decrease when I press the volume button.

Any advise? claim warranty? I bought it last year August.
[Device Reviews and Information] soulfunkdjx:
??? Strange... Obviously has nothing to do with the new battery. Try factory settings or better try flashing the rom again with the official guide from ulefone's site. If not this solve the problem then the problem will be inside your hardware and needs a person who knows about fixing phones. On the other hand you can try the warranty process but it'll take 3 months to take it back plus the money it'll cost to send it. Maybe start thinking of buying the ulefone power??? Until now all the customers they say only good comments about this phone.
[Device Reviews and Information] peido:
LOL

I would not recommend another ulefone, but that's just me.
[Device Reviews and Information] soulfunkdjx:
This model had serious problems (mine has nothing at all except the swollen battery). Untill now the other ulefone models are working great and you can see it from the comments.

Anyway the choice is yours. ;)
[Device Reviews and Information] soulfunkdjx:
Now read what it started to do... I plug the usb cable to charge my phone and is charging very very very slow. One hour now and my phone charged only 5%!!!!!! If i take out the battery for 5 minutes and insert it again it will show me 90%!! The funny is that it holds later normally as 90% about one full day. I tried also my method for calibration but is not fixing. Maybe the reason is the swollen battery. I am waiting the new ones to check it.
[Device Reviews and Information] Moolok:
Smallest things can make a difference. Even a small one.

Yesterday I went to my operator and got a new SIM-card. The old one was micro size and since I now use SIM slot 1 which uses mini size I had to use an adapter. Old card was about 4 years old.

To my amazement with the new card phone picks up LTE carrier a lot faster and stronger than with the old one.

My device have an unresponsive row on top screen when pressing.

On test i can draw but i cannot press. The device is rooted and have CM 12.1 as OS.

Can anybody help me?
[Device Reviews and Information] soulfunkdjx:
Maybe try to flash again the original. If it remains is a hardware problem.

I can't wait for mine. I have ordered them 3 weeks now and haven't arrived...

Suddenly my screen started to unglue from the metalic frame...!!! Also my back camera stopped working but i'll open it and check the connectors as the flashing didn't solve anything.

COME ON BATTERIES PLEASE COME TO DADDY!!!!
[Device Reviews and Information] handful17:
After getting my new batteries I was again happy with my BT2....and now I've gone and cracked the screen :mad:

I'm not good when it comes to fixing electronics and have no confidence I would be able to complete a satisfactory repair (if I could get a screen which seem quite hard to come by) so looks like I will have to change to a new phone. First thoughts are either a Ulefone Power or a Redmi Note 3 Pro. The Redmi is quite a bit more expensive and overall the better specced phone but the battery life on the Power looks amazing. Is there anything else I should consider in the sub $200 bracket?
[Device Reviews and Information] soulfunkdjx:
I believe power is value for money. I am very close to order it...
[Device Reviews and Information] handful17:
I like the look of it but the 16gb memory is a bit of a deal breaker for me I think because I use 2 sims.

I've ruled the Redmi out as well now, no 4g support for my network in the UK. Now looking at the Elephone P9000 and Oukitel K6000 Pro.
[Device Reviews and Information] soulfunkdjx:
Good choices though...Elephone p9000 is also an incredible phone. Supports 2 sim cards and sd card the same time?
[Device Reviews and Information] handful17:
No, one slot is sim or memory card but with it being 32gb memory I can probably live with that compared to just 16 on the Ulefone Power. It's a shame they all seem to be moving to a choice between 2nd sim or Micro SD, I loved that about the BT2.
[Device Reviews and Information] Tertsi:
Digged my crappy BT2 out of the junk pile (i had given up with this one) and flashed the CM 12.1 rom couple od days ago... tadaa so far it seems to be 90% more stable than the stock roms. Well fingerprint and bluetooth streaming are known bugs on this rom. If they get even the BT workin then it would be just fine. 48500p on Antutu no sweat!
[Device Reviews and Information] soulfunkdjx:
How does the battery doing? Is it better from original rom? Or is showing again 1% and keeping on for half an hour? We want more stable % indicator.
[Device Reviews and Information] Tertsi:
forget abut it- it seems my joy was premature... the ****fone started to do it again... after couple of charge cycles now it shuts it self down 1-4 times a day just like before.
[Device Reviews and Information] madrugao:
Do you remember if the back camera chip is the one just next to the front's camera?
[Device Reviews and Information] Dekay99:
I agree with tertsi, cm12.1 solves a lot of problems on bt2. Like sudden reboot and hang on ringtone.

Al least in Day 3 ;)

But how secure is it? Toto bad That Bluetooth audio does not work.

And Will it stay this way

Dekay99
[Device Reviews and Information] Moolok:
I've been using CM12.1 about a month now and it's way better than stock. Too bad about that audio streaming with Bluetooth bug but that's about only downside with this ROM.

My new battery is now properly calibrated and no more sudden drops in charge etc. I can go a day without charging now unless I play or watch movies. Then ofc recharging or power bank is needed.

About security I think it's at least as secure as stock. More so even as the stagefright is fixed.
[Device Reviews and Information] jlev:
Hi - I recently replaced the display on my Ulefone be Touch 2 with one from AliExpress. Installing the new display is reasonably straightforward (hint: use a hair dryer to soften the glue first when you remove the broken display, and again before you put the new display into place).

However after that the screen doesn't display correctly. According to the seller this is normal, and can be fixed by flashing the ROM. The seller even gave me instructions and all software (flash tool and image files) to do this part. However even having done this the screen is still not displaying correctly.

It is hard to describe what I'm seeing but it's like cyan/blue "noise" on the screen, and impossible to make anything out.

Would be interested to hear from anyone else who has experienced this. At the moment all I can think is either 1) the new screen is broken, or 2) I need to leave the phone alone for longer while it builds android post-boot. Unfortunately I can't see anything on the screen which may give me hints as to what I should be doing.
[Device Reviews and Information] soulfunkdjx:
Sorry mate. But at the point you are right now try to open It again. Sometimes if you are not sure about something it's better to find a technician. So try removing It again or fing a technician.
[Device Reviews and Information] jlev:
Got the screen working!

But flashing wiped the IMEIs, so I need to go back to a ROM that can be rooted and will run MTK Engineering : (
[Device Reviews and Information] soulfunkdjx:
So how did you make it?? Did you open again the screen?
[Device Reviews and Information] jlev:
The problem with the screen was because the documentation on the Aliexpress vendor's didn't have enough detail (it was also in Chinese). I had to use trial-and-error until I found a configuration which (barely) worked.

For some strange reason flashing s7tyler's lk.bin (where I believe the issue was) didn't fix the issue. You had to flash the vendor's lk.bin file first, then reflash everything.

To be honest I'm not quite sure where my IMEIs got erased. I flashed Cyanogenmod before I realised it was gone. And MTK Toolkit/etc don't work under the Cyanogenmod ports : (
[Device Reviews and Information] soulfunkdjx:
s7tyler's lk.bin and vendor's lk.bin what are these? Drivers for the screen?

If you are rooted you can use ''Chamelephon'' application from play store to add your IMEIs

it is dead after OTA update..then flashed fw with orj updater,

now it is workng but blackscreen..
[Device Reviews and Information] soulfunkdjx:
Ok piece of cake...

You just flashed the wrong rom. The same happened to me.

Follow the steps from the official site of ulefone.

http://ulefone.com/download/betouch2.html

There are two versions of our phone. If you get black screen with option 1 then you have to flash option 2.

I flashed option 1 and i get also a black screen.

But option 2 was working perfect.

Your phone is not dead so don't worry.

Please tell us if you manage to open your phone. I am waiting...
[Device Reviews and Information] t-mobile_mda:
i really tried two roms.. same condition.. blaackscreen..
[Device Reviews and Information] soulfunkdjx:
Did you tried with the link i gave you?

With the "agold" flashtool that ulefone provides?
[Device Reviews and Information] t-mobile_mda:
of course i did.. these files stored in my HDD.. i really did..
[Device Reviews and Information] soulfunkdjx:
Ok.

When you are flashing the bar goes till the end?At 100%? Try with the sp flashtool with the roms you already downloaded. Load scater file and chose firmware upgrade. If nothing happened again try format option (you will lose your imei but if you root your phone you can easy add it again). Maybe accidentally you download the same rom two times? Did you made OTA update when you were rooted? Answer all these questions.
[Device Reviews and Information] t-mobile_mda:
w.b.r.
[Device Reviews and Information] soulfunkdjx:
So this is the problem. You update your phone when you were rooted. You bricked it. Some people made the same mistake in the past and they opened the phone by flashing it. I don't know why you are still having a black screen. I'll search it and i'll contact you if i find the solution. In the meantime try to read older posts from this thread as you'll find some answers.

CM 12.1 never worked for me as it has a lot but a lot of options (which is good) but in my ocassion no as i want something more simple and with a better battery life. I'll test the new one later. Until now i'm with the vibe rom and is very good.
[Device Reviews and Information] soulfunkdjx:
I'm back...i installed modulaterom on our phone and so far all good. It seems to be the original ulefone's rom with the difference that the programer added an android 6 look and some goods apps. Until now i didn't find any bug. Everything is working great. And the home button, and fingerprint scanner, and gestures. My only complaint is that the volume is so loud that makes a distortion effect if the volume is maxxed. I installed engineer mode to fix it but is not opening mtk settings. I'll try it via the dialer. Tomorrow i'll come back to tell you the battery's life as i did a calibration and needs a full charge to see the right result.
