[Device Reviews and Information] Carlito Z3:
Hi guys,

I received mine on tuesday (ordered on chinavasion, shipped quickly with little gifts to excuse for the delay). I worried a bit because it was not perfect a the beginning:

antutu score 20000

flash light that was not working after 3 tries

really slow to charge

and in fact after one night, everything is perfect:

antutu score ~45000

flash light OK (I guess there is a security when phone is hot or battery not charged, that was the case after many hours of apps configuration)

normal time to charge

BUT, I have a real annoying issue with my LG G WATCH R...

When I wanted to pair it with the phone, I had to factory reset it (I though it was a limitation of wear if you change you phone); and everything was OK... but after one day without my watch on my fist, when I came back home, impossible to connect the watch to the phone :( (on the phone, wear shows "connecting")

I decided to factory reset the watch again, and once again everything was OK (fast pairing, sync etc)..

And this morning... patatra, I can connect the watch to the phone...

That's really annoying...

EDIT: I have no issue with bluetooth in my car, it connects everytime I enter my car...

I contacted ulefone, and a good point is they answer quite quickly to the questions...
[Device Reviews and Information] aszu:
OK, so this phone is a bit of a scam:

1. Poorly optimized, laggy Android 5.0 ROM pretending to be 5.1 (at least it is pure stock, no bloatware...)

2. I measured battery capacity using external meter and it is about 2100mAh - and this is being generous, not accounting for charging efficiency

3. "Fast charging" is outputting 1.3A using bundled charger - using better charger does not seem to make a difference. It takes a bit over 1.5 hours to fully charge the phone, which confirms ~2000mAh battery capacity.

4. As mentioned, phone tends to overheat, no sure if this is because of poor cooling system design or there is something wrong with the software and it runs chips at higher voltage / frequency than required.

5. 'TouchID' is temperamental at best (in many cases it just does not work) and the build quality/feel of the physical button is atrocious.

Maybe it is just my battery that is subpar and this phone is going to receive some awesome support from the manufacturer (proper 5.1 ROM, fixed lag, power management and overheating) - but it is unlikely, considering that the previous version of this phone received very little support.

I can't really recommend this phone at this point (unless you need iPhone 6 clone for some reason), give your hard earned money to a more honest company instead (Lenovo, UMI? Jiayu?).

It is kind of a shame, because the build is actually nice (except this unfortunate button). I might be picking something with the new 'helio x10' next, in the hunt to replace Jiayu S3 which has its own set of problems (poor call quality, dreadfully slow charging, wifi wakelock drain).
[Device Reviews and Information] Rizera:
Wow, what a letdown. Still:

1 - That is a tricky one. Maybe CM or software updates from Ulefone could solve the issue but still, quite hard to happen.

2 - 2100? Wow. How did you manage to measure this? That is very far from the "official" data.

3 - That was pretty much expected, I guess. They advertise 35% in 15 mins, but this is very hard to believe. 1.5 hours to fully charge isn't slow, though.

4 - Is this a SoC issue or software issue? I don't game much but still, it is a letdown.

5 - I've heard from various reviews that TouchID on the original Ulefone Be Touch was quite great. Why would they change it?

Again, thanks for your feedback.
[Device Reviews and Information] aszu:
1. Would be nice, but it is unlikely to happen any time soon, I don't think there is even one fully working CM for those cheap MTK devices out there, and Ulefone is one of the most niche / unheard of brands.

2. I used device like this: www.ebay.com/itm/221738231479 - it has proven accurate in the past. Also simple calculations from point 3 prove that the battery cannot be 3Ah.

3. It is not slow, but if you consider the fact that the battery is just 2Ah, the charging time is just normal.

4. In theory they could use some inferior bin of MTK chips that require higher voltage to run. Or maybe kernel governor is too aggressive and keeps the CPU/GPU in a high power state for too long (maybe so the phone can boast 'better' Antutu score). Or maybe they skimmed on a piece of copper to dissipate the heat more efficiently (then it does not really impact battery life, but my cause temperature-induced throttling during prolonged gaming, etc). Hard to tell without looking at the governor and frequency / voltage table in the kernel - I might have a poke a bit later.

5. It is just a hassle to use as it quite often just does not work - but maybe it is just my sensor or my finger :)

It is not a terrible phone or anything, but for the money you can do better. I think everyone considering purchase should probably forget about this contraption and get something like Lenovo K3 Note instead, which is better in every aspect: lower price, smooth software with proper support (both manufacturer and community), true battery capacity, noise cancelling microphones, good audio, display without nasty pink hue, notification LED, etc. Unless you *really* want iPhone 6 lookalike or 'TouchID' feature (that is actually a hassle to use due to spotty performance and terrible button design).
[Device Reviews and Information] thor2001:
Well, it isn't that simple, if you want full 4G-compliance (especially FDD-LTE Band20/800 MHz) in Europe.

This is a BIG issue, even with Xiaomi, Meizu, ZTE ...

[Device Reviews and Information] Guerreiro_BR:
This problem happens with all that already have ?
[Device Reviews and Information] WearySky:
1 - Funnily enough, I find the AOSP build on this to be less laggy than that on the Elephone P7000. But this weird "5.0 pretending to be 5.1" thing also seems to screw up XPosed framework (which works fine on the P7000). You have to install the 5.0 version of the framework, but then none of the modules I tried seemed to work.

2 - Maybe you got a bad battery? Because for regular day to day use, I'm seeing identical battery life to my K3 note. Though this is only in non-gaming situations... If I do any gaming, it drains the battery like a mofo (this is related to point 4, I think)

4 - I think there's definitely an issue with the firmware, since in my experience the overheating seems to be related entirely to high-demand applications. If I'm just surfing the net or reading an ebook, it is fine. Gaming is when it really goes bonkers.

5 - I find *all* of these touch fingerprint sensors to be finicky as hell. If you don't get the angle *just right*, it rejects you. The P7000 was exactly the same.

The K3 note is a fantastic phone with tons of support... But I haven't been able to get OTA updates working when rooted/debloated. And you *have* to root and debloat the damn thing, because good gracious that's a lot of Chinese bloatware. So any time you want to update, it's a bit of a hassle.
[Device Reviews and Information] aszu:
1. My point of reference is 'beta' Lollipop 5.1 ROM for Jiayu S3 (same hardware platform), with is buttery smooth (I mean, *really* smooth, like iPhone-smooth) compared to laggy hell in Be Touch 2. I have not seen any of the Elephone phones, I am afraid. Try changing Android version to 5.0 in build prop, also make sure api level (ro.build.version.sdk) in build.prop is set to 21 (which is 5.0 API - I think the parameterit is already set to this value) - there is a small chance that it might help with Xposed (if it uses those values to determine what to do)

2. My battery is definitively 2Ah (even though the label says 3Ah), but it is very likely that there are different batches of batteries out there and some are better than the other.

4. Not sure if the governors and frequency table are tweakable in the stock kernel (don't have a phone with me at the moment), but might be worth checking the parameters with something like Kernel Auditor.

5. Yep, waste of time...
[Device Reviews and Information] WearySky:
Thanks for the build prop tip, I'll try that after I finish my wifi youtube test (currently at 78%, after running for an hour - battery temp is 39 degrees C)
[Device Reviews and Information] r_kalar_2:
Waiting for your result bro.
[Device Reviews and Information] WearySky:
So, ,it looks like my work wifi kicked me off and I didn't notice (awful wifi there). I ended up getting about 4.5 hours, 4 hours of which was over LTE. There's 4gb of data I'm not getting back, whoops. Re-running today, with the latest firmware update as well. Incidentally, they seem to have fixed the overheating problem with the updated firmware, I was playing CSR racing for 30 minutes last night and the temperature was pegged right at 35. So that's good, at least, and may mean improved battery life too.
[Device Reviews and Information] r_kalar_2:
Very good news. Thank you
[Device Reviews and Information] WearySky:
Final time: 5 hours, 15 minutes of youtube streaming over wifi. Screen brightness right in the middle.
[Device Reviews and Information] ferbulous:
Hi, did you get xposed tweaks working now?
[Device Reviews and Information] aszu:
OK, a bit more feedback after using this phone for a day as a 'daily driver', comparing to Jiayu S3

TL;DR: this thing is unusable for me in its current state.

1. Battery life is roughly half of Jiayu S3 (with true 3Ah battery, as measured by my meter). Yes, it does charge much faster than Jiayu, but that is simply because charging current is 40% higher and battery capacity over 30% lower.

2. Device is plagued with lag and stutter (100% pure stock ROM, flashed directly with SP Flash Tool), it is so bad that it makes SwiftKey almost unusable - if you type too quickly it actually detects individual taps as 'swipes' and comes up with some random predictions.

3. Touch digitizer has some accuracy issues and often does not recognize input (could be partially due to point 2).

4. After playing with 'TouchID' for a while I eventually just turned it off - not worth the hassle. The button itself is noisy and flaky.

5. Wifi performance is bad (at least on ac) - it struggles to reach 10Mbps, Jiayu at the same spot reaches 50Mbps.

6. ROM is a total mess, fake '5.1' version tag, log is full of debug stuff that should not even be there and spammed with various errors (wifi, etc).

7. Headset call speaker in Ulefone is much better (nice, loud sound, voice easy to understand) than Jiayu (which is simply terrible in my unit, makes rattling noise when the volume is too high), but microphone quality is actually worse - could be due to just a single mic design with no noise cancellation.

8. Minor annoyances like no notifcation LED, the device is actually a bit to tall which impacts operation comfort.

9. Did I mention pink-tinted display? iayu's display is not perfect either (it has slight greenish tint), but it looks much better in comparison. And to clarify: I do not have a problem with warm white balance (when the display is sightly yellowish), but in case of Ulefone white is literally pink - which looks bad and makes content darker than it should be.

It is a shame because I really wanted to like this device, the build quality is not bad and '2.5D' tapered glass has a nice feel to it.

Ulefone really need to get their **** together, stop this crap with fake '5.1' ROM and fake batteries (or improve QC as at least some of them are clearly inferior), release optimized, true 5.1 image (butter-smooth 5.1 Lollipop ROM from Jiayu proves this is possible) and maybe then this device could be worth considering (but not at the overinflated RRP of S$229.99, while K3 Note sells for $145). At the moment I would advise to stay away from this phone.
[Device Reviews and Information] MUG3NHC:
Thanks for your tests, although a lot of people seem to have much better experience with this phone than you…
[Device Reviews and Information] :
I have this same problem. I just rooted my device and pushed the files to /system/media/* for the time being.
[Device Reviews and Information] azeemzuhair:
The external SD card and internal phone storage modules conflict between each other. This is a serious bug. Ulefone needs to sort it out immediately. As of now, i do not use the microSD card but dump all data into the internal storage alone instead. What a bummer...
[Device Reviews and Information] fractaluser:
Haha this phone, is most amazing!

Had half battery, havent used the phone at all, now at luch at work i take up the phone, pres on Textra, write 4 words and as soon as i press Send, the phone dies. Went all black, doesnt respond to anything, took out the battery, tried to boot, nothing, not even recovery. Put it in the charger, nothing shows, pitch black and doesnt respond to anything.

Amazing! How they manage to make a totally worthless phone like this is beyond my senses. I cant do anything but laugh and live with the loss of 180 euro....

EDiT: Haha wtf, okey so it started now, with 2% battery, most amazing, so i read the battery indicator is fudged. Anything thats working on this piece of hardware =) ? lol
[Device Reviews and Information] azeemzuhair:
This is a serious standby bugs that emerges in the OTA August update.

Roll back to July ROM if you will.

Regarding battery is flat, give it 5 minutes to charge. It will show the 1% charged after 5 minutes.
[Device Reviews and Information] shohid1234:
Yup, serious issue with standby. Whatever I do, even with data off etc the phone with the new update is always "awake".

Would have thought something like with would have been found immediately by ulefones software testers.
[Device Reviews and Information] Guerreiro_BR:
Someone already bought the tempered glass film with blue edge?
[Device Reviews and Information] Yeman56:
There is a .log file in the SD Card about the August update, it's not possible to open it with the default app but with another file manager app (like Cabinet) you can. It contains a lot of informations apparently but I accidentally remove it. :(

[Device Reviews and Information] fractaluser:
Yah will do the July Rom, problem is that wifi wasnt working properly with that one but yeah, at least i can use the phone as a phone haha. Anyone know how many ppl are employed at ulefone?
[Device Reviews and Information] azeemzuhair:
My unit does not have Wi-Fi issue from the beginning. For me, this phone Wi-Fi reception is one of the strongest.
[Device Reviews and Information] degady64:
I bought a 64GB card and the phone does not see it. What can i do?
[Device Reviews and Information] azeemzuhair:
Lousy BT2, isn't it? The SD card slot does not support UHS-1 SD card format.

My Meizu M2 Note and ASUS ZenFone 2 supports UHS-1 SD card out of the box.

Format your card to FAT32.
[Device Reviews and Information] Andy4Shurr:
They don't have software testers. They don't even have their own dev team, they just use freelance devs they find on this forum.
[Device Reviews and Information] azeemzuhair:
LOL for that comments....
[Device Reviews and Information] Andy4Shurr:
My comment? haha, I'm not even joking.
[Device Reviews and Information] Moolok:
Not true. I have mounted Sandisk Ultra microSDXC UHS-1 64gb card and it works fine. System shows 59.46gb usable disc space.
[Device Reviews and Information] wallahboy:
wow this is hilarious... :D so far I did not encounter any problems with the phone. hope it stays this way because when reading stuff like this, i do not have much hope for cusomer service ^^
[Device Reviews and Information] azeemzuhair:
See... Different batch of BT2, different hardware specs... All of us are having different issues altogether...so, stop whining if your (ie any of us) batch is giving lots of trouble for you. Just sell the phone in the Craig's List mall....at least you'll get back some of your money rather than suffering owning a phone that makes your blood pressure sky-rocket high.
[Device Reviews and Information] Ormbett:
Dont be scared because of all whining in this thread. Most people here have different problems with their phones and just let some steam out here. People with no problems enjoy their life instead of being here ;)

Another option if you run into trouble is to communicate directly with ulefones CS - service@ulefone.com I know they answer at least some of the mails they get.

Kind regards
[Device Reviews and Information] Heshamvido:
The phone is getting really hot. Any advice ???

Also, how to decrease the brightness ???, it is so damn bright even in the lowest brightness degree...

For the battery poor calibration, I chatted with them and they advice me to discharge the phone completely then put it on charger till it reach 100% while the phone is shut down. Then power up the phone and disconnect it from the charger and leave it without usage for 30 minutes. Then put the phone back on charger for another 30 minutes.

I did that and it worked just fine for me.
[Device Reviews and Information] azeemzuhair:
Hot = lousy MT6752 SoC

Blue Light filter app will ease ur eyes:

[Device Reviews and Information] r_kalar_2:
Use screen filter app from play store.
[Device Reviews and Information] Moolok:
I need to try that.

Otherwise I'm very happy with my BT2 but only thing that bugs me is the battery: it drains too fast. I took my phone off charger this morning at 6:15 and battery was 100%. Below is the situation after about 8h with really, really minimal use (few photos and SMS since I was at the funeral):

Phone idle, Android system and Google services were using that much juice while doing nothing. I hope next update optimizes things further.
[Device Reviews and Information] Heshamvido:
Well, after I tried their method of battery recalibration and it worked fine. Today my phone is acting really weird, battery at 43% and the phone is in stand by mode, suddenly, it starts to ring continuously with the screen dimmed. Then I removed the battery and put it back, power up the phone, battery @ 7% !!!

Also about the heat problem, my CPU gets over 55° C... This is so damn hot.

This is bull****,

Thanks for the reply ghiurtuv

But the option comes after the app started working without connceting to the pc and the usb backup enabled there is no chance to connect to the helium server.

If there is a way please explain me in detail.

The slow typing is because of the digitizer's response lag... We'll need a statement from Ulefone on this.

Now, after to many problems with phone over heating and battery poor calibration, the camera stopped to work. Just shows me white screen. I made system restore and the camera app is gone away. I flashed the 2/7/2015 firmware to solve the phone over heating and battery calibration problems. But the camera app still not exist, so I installed google camera and camera360 apps. They both aren't working , they just show me error message that say can't connect to the camera.

What to do ???

Tweaked ROM, all working perfect except...

So I messed around with my ROM, changed a few settings & edited a bit of code and my phone is running great. Battery - about 6 hours with heavy usage. Last night i charge it before bed, left it unplugged and woke up to 97%. Happy with idle & heavy. My one and only issue is by back camera working on Snapchat (not sure if it's ROM related or app related) but when I take a video with back camera I get some weird layers of colour and about 7 vertical green or purple lines on the right hand side. Can anyone help please? Cheers.

I just let my BT2's battery run completely dry. I was actually amazed: battery showed 1% left and it kept going. I was able to browse YouTube over 30 minutes with that last one percent when it finally shut itself down. Now it's powered down and charging. I decided to try that battery calibration trick some one here earlier mentioned.
[Device Reviews and Information] Rizera:
Can I kindly ask you to give more detail on what you have changed on the ROM? Did you work on the July or August ROM?
[Device Reviews and Information] Iwholden:
Well I updated to august but it was unbearable so I went back. I set the CPU slightly slower, force uninstalled some background services that were apparently needed but not, changed the DPI, changed the minimum brightness down further. I did do a few other bits and have everything written down on the computer in the event I messed up and needed to change stuff back. It was kinda trial and error but the fluidity & battery life are awesome now.
