Sure I would also go for the original if I could get my hands on it, but I just had this flipcover laying around and could actually then use it for something.

My UMI ZERO is a pre production sample, so it is hard for me to compare these problems, as my phone is not 100% the same - and I don't have reboots on mine. It guess it could be a unknown problem in the factory on the final devices, or something else - I don't know. I have also asked UMI about it, but they can't give an answer on it. But they are trying to do a lot of tests to find the reason, so they hopefully can fix it. Also it seems not to be all devices who are hit by this, but only some.
[UMi ZERO Guides, News, & Discussion] politby:
Has anyone tried a microSD card larger than 32GB? Specs say up to 32 but I've had other devices which had the same spec but worked fine with a 64GB card.

Appears so. I placed my order on 29-Dec, they shipped 6-Jan and it's out for delivery here in Sweden today on DHL.

Now to see if it is as good as most seem to think, or as glitchy as some say. ?

Noise

Hey, what happen with the noise during a phone conversation. I opened the engineer mode and tried to increase the amount of the mic, but that didn't work. People can't understand what i'm saying to them.

Is there something that I can do for fixing this problem?
[UMi ZERO Guides, News, & Discussion] XynanXDB:
Pls do share ur opinion when u got it .Thanks

I have read some of the recent forums that the biggest problem now is the mic. Many commented that it sounds like static or wired noise.
[UMi ZERO Guides, News, & Discussion] clubvibe:
From all the issues I have the mic is not one of them. I've asked some people about my reception. They respond it is clear :) So I seem to be safe there. However my 2nd SIM is still not working. I wonder if it will be solved in firmware or that I need to send it back.
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
I received my UMI Zero today, and I can only say that it is amazing.

The screen and the camera are awesome, it has good wifi and 3G reception and the design is very cool. Also, I didn't find any bugs or issues yet, everything is how it should be :)

Since u cant use ur sim 2 slot, can u use ur microsd
[UMi ZERO Guides, News, & Discussion] politby:
Okay, so I received my unit today. It has the 3.01 version so I thought I would update it to the latest beta version before I start using it.

I have followed the update instructions to the letter by installing the drivers and the pdanet application.

Unfortunately the flash tool does not react at all when i connect the powered off phone to the USB port while holding the volume down button. The phone displays the recovery icon (green 'droid') and I can get into the menu by hitting the power button, but despite numerous attempts I cannot get the flash software to do anything.

A normal connection works fine for standard file transfer (connected as media or legacy USB device) so I doubt it is a driver issue.

Any ideas?

Why they offer another screen protector? Isnt the screen protector and the Z case included in the package?
[UMi ZERO Guides, News, & Discussion] politby:
I guess a way for the resellers to snatch some extra revenue. ?

Given that the phone has Gorilla Glass I would not put a plastic screen protector on it. It will just ruin the experience.

I use tempered glass screen protectors on all of my other devices. I will put one on the Zero soon as one becomes available.

I think it is hard to get one. UMI's isnt shooting high up as Xiaomi, Oneplus, Meizu, etc.. They just play the game silently.
[UMi ZERO Guides, News, & Discussion] Tarnak:
To be honest, IMO, there is no point in placing protector thing. I couldn't stand to place any crap on display. It's enough resistant for regular scratches, dropping it ends with sh*t anyway. I wouldn't place protector to lower the experience of phone usage.
[UMi ZERO Guides, News, & Discussion] 06ashiqs:
The exact same thing happend to me. The pdanet driver is wrong.

Just to confirm: when you plug into the pc you see an open android with a red triangle and an " ! " mark inside the triangle.

It turns out that the thing you see is the android recovery menu "without the menu writing" you will see the writing when you press the volume up/ down button (cant remember which one). You may need to do some trial and error as thats what i did. Long press the power button to turn the phone off.

FIX: after much research...

you will need to manually install the mt6592 vcom drivers (its a bit of an odd way). These vcom driver assign your phone to a port on your pc e.g. COM:3 so then your pc can flash your phone while in download mode. The method is the same for all mediatek chips from mt6577 and up. You will need to google how to do it (i cant link websites as i am a junior member). I personally used a file for mt6577. Just type in google how to manually install mt6592 vcom drivers and you should find it.

Once the drivers we installed properly then i followed the process again and it worked perfectly.

Hope this helps.:D

Im still not sure whether to buy this phone, cuz it as buggy as hell. But, with the specs it offered it it the best bargain. Any other phones to recommend?
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
Well, I was amazed by this phone until I discovered a problem. When I plug in the earphones, it only produces mono sound instead of stereo sound. This is strange because both right and left earphone are playing... Anyone knows what it can be?

Thanks.
[UMi ZERO Guides, News, & Discussion] XynanXDB:
Hmmm.. If loudspeaker support stereo, then it might be a bug for earphones
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
But do you thing its a bug from hardware or software? I tried with 3 different earphone, and all are the same. But it's strange the fact that both sides play sound and the phone detects the earphones correctly :/
[UMi ZERO Guides, News, & Discussion] XynanXDB:
Try changing some settings.. See how it work. I think there is a sound enhance in it
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
I already tried that, but it didnt solved anything... I went to settings>audio profiles and tried to check and uncheck the options in sound enhacement. Is there any other settings besides these ones?

I'm a bit sad about this problem, cause the rest of the phone is amazing.
[UMi ZERO Guides, News, & Discussion] politby:
I am guessing you have headphones with an inline microphone and playback controls? Most likely this problem is caused by the phone's headphone socket being incompatible with the TRRS (tip, ring, ring, shield) plug of your headset.

Try with headphones without in-line mic (TRS plug) and see if they work.

Also with your headphones WITH mic, try holding in the answer/pause or skip fwd/back button. This fixed it when I had the same problem with my Chinese tablet.

[UMi ZERO Guides, News, & Discussion] politby:
Unfortunately I think this is the norm rather than the exception with most of these Chinese sellers. They are generally quick when it comes to selling and shipping, but anytime there is a problem you're SOL.

I recently purchased a Windows tablet from a seller on Aliexpress. Lightning fast shipping and excellent pre sales communication. But a few days ago the tablet suddenly died. And of course, the seller is ignoring my messages. $200 down the drain ?

Hey. So I sent a message to UMI yesterday about the earphones problem, and this was their answer:

"Dear Miguel Ferraz, we've already fixed the problem with the sound in our new update that must be available today or tomorrow. Sorry for inconvenience."

So, I hope this is just a software bug and that an update solves the problem :)

---------- Post added at 02:37 PM ---------- Previous post was at 02:31 PM ----------

I already tried with every kind of headphones, and the problem it's the same. But is strange cause it detects them well, just the sound output is mono instead of stereo. Let's hope this is a software bug like they said, and that the new update solves the problem :)
[UMi ZERO Guides, News, & Discussion] grikster:
Hello guys,

anyone notices some sound glitch or sound break on normal phone calls? The phone is really good for the price, build, screen, camera, but it lacks of better software by now, some glitchs that should be gone by now.

First time using a chinese branded phone, hope i wont regret. The phone is actually great for the price, great screen.
[UMi ZERO Guides, News, & Discussion] politby:
Thanks, that did it! My update was successful and I am now putting the phone through its paces.

So far everything seems fine. I am not a power user by any means but all my apps installed without issues and run fine. No problems with wifi or bluetooth, my sony bluetooth headset works great and wifi performs much better than on my Xperia Z which this phone replaces.

Audio quality on phone calls is perfectly okay. I always use a bluetooth headset so I cannot comment on the quality of the built in microphone and speaker.

I use Spotify a lot and I cannot say there is any difference in audio quality compared to my Xperia.

Only possible complaint is that the screen colors seem over saturated. Maybe there is a way to adjust the screen color balance.

Guys,

I've flashed the Y800_UMI_20141231 and is ok but can reset the phone from time to time. I had such behaviour on texting and incall.

If UMI planning to release new firmware in couple of days I'll wait 'till then.

About color saturation, true, they are vivid but it's strength of this phone. You can play with brightness or try to dig with gamma settings or use tool like "Screen Adjuster Free" RGB + contrast + brightness control.
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
The screen is one of the things that I like most on this phone, it's simply awesome!
[UMi ZERO Guides, News, & Discussion] politby:
I definitely agree the display is impressive. The black levels are easily the best I have seen on a phone. The color saturation is a minor nit pick.

The built in speaker is cr*p.

For me the update is not working.

I copy the ota-update.zip in the sd card. Then Settings -> About phone -> System updates -> Start update. I receive a warning that the phone will restart and press ok. The phone restarts but just boots up normally, without performing any update. It remains with Buildnumber UMIZero.V3.01.

What am I doing wrong?
[UMi ZERO Guides, News, & Discussion] Tarnak:
I've heard that it's not ota, needs regular flashing by sp flashtool.

Errata:

I've downloaded it and it seems to be flashable by OTA or CWM.

I've found comments in UMIdigi, somebody couldn't install by ota:

"Its not OTA Update!!!!!! You need flash, with SP Flash Tool V5.13.52 or newer!!!! (Ofcourse, if site up…)"

Did anybody tried installing this by CWM,flashtool?
[UMi ZERO Guides, News, & Discussion] nnexuss:
Nop.. you can use the both ways!
[UMi ZERO Guides, News, & Discussion] Ties(to):
For me it worked the easy way and back up of files / apps was not needed, now on build# UMIZERO.V3.03!

Yes, i've copyed the zip file in the root of the SD card, but nothing -> just reset and normal boot.

I than thought of trying to manually enter the recovery mode of the phone. But I am unable to do it.

I power down the phone, i hold VoldDown and Power, but the phone just boots up normally. If I try VoldUp and Power I enter in some factory test mod which is in chinese.

Can you boot your UMI Zero in recovery mode? If yes, how do you it?
[UMi ZERO Guides, News, & Discussion] arna1958:
This is what I understood.

If you have the CWM installed you cannot do the ota update.

You have to flash the rom following their instruction

After the flash you will see that the build number is 3.01 and your recovery will be replace with the original one

Now you can update the rom via system update and it will works.

After the update the build number will be 3.03

I know that it is strange, but that is what happened to me

[UMi ZERO Guides, News, & Discussion] mightystorm:
So I've managed to solve the issue....

What I did was :

- first I used SP Flash to flash the ROM from 04.01 posted on needrom.com

* Attention : In order to make sure that everything is ok:

- open device manager on your PC

- shut down the phone

- connect the phone to PC without pressing any buttons

- you should hear a sound and in device manager, in the section Ports (COM & LPT) it should appear MediaTek Preloader USB VCOM Port

- after ~1.5 sec you will hear another sound, Mediatek preloader will disappear and the phone will switch into charging mode

- if all this happened accordingly, you are good to flash with SP Tools

- after writing ROM 3.02 I was also able to update to 3.03 by using the OTA method (put ota_update.zip) inside sd card and use the System Update

This should help you to have 3.03 ROM in case you are struggling like I did :good:

I was wondering is someone is able to do some Bluetooth testing.

I am using a Sony SBH50 stereo headset which works perfectly with music listening but sometimes during phone calls I am noticing dropouts and interference. This happens even when the headset is very close to the phone so it is not a range issue.

[UMi ZERO Guides, News, & Discussion] Tarnak:
My idea was similar to [MENTION=6308538]mightystorm[/MENTION] on post 507 described. For all of you who have problem with stability try first stock 3.01 + OTA and later after checking that all is fine do a 3.02 from 4/1/2015 + OTA. IMO, OTA is kind of update on existing system not FW full update with data factory resetting etc.

Can be a situation with 3.02+ (unofficials FW from umi zero) that some UMI changes in ROM were problematic and UMI rollback these changes to the 3.01. So, after OTA you will have still unstable system because your installed base ROM is buggy.

I'm actually on 5/1/2014 + OTA, we'll see how it's working.
[UMi ZERO Guides, News, & Discussion] mightystorm:
I have experienced 1 reset so far after the update. I had 0 resets while on 3.01 stock.
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
So far so good, never had any reboot or bug with this update, neither with the original software.

[UMi ZERO Guides, News, & Discussion] politby:
I just tested with a pair of Sony earbuds without inline mic (TRS plug) and I definitely get stereo audio. But there are other problems - the left and right channels are reversed and the sound quality is terrible, with screeching highs and no bass to speak of.

Again, with Bluetooth headphones I don't have these problems, channels are correct and audio quality is at least as good as on my Xperia Z.

This suggests a physical problem with the headphone socket. Can't believe they let this through QC...

[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
I tested with some sounds, and the problem with me is that the right channel doesn't work, but the left channel transmits to both sides of the headphone... So it's worse than mono because I only hear the left part of the music on both sides.
