Can you confirm how you tested each band?

did you go into engineering mode, select ONLY 850mhz, turned off all others, saved the settings, shutdown the phone. Removed the battery for 30 seconds then restarted and still got a 3g connection?

Would love to know more on your testing because I am also from Australia (melbourne) and looking at buying a chinese phone and want to make sure it works on 3g in Aus, specifically kogan (telstra - 850mhz)
[Android General] bgdwiepp:
No, instead I tested by using both an optus and a telstra simcard individually, I drove to an optus 2100mhz tower and used the optus card, I got a umts connection, was able to make a call to 1194 and use hspa data. Then i drove to an optus 900mhz tower, same test, successful call and got hspda data. Then I drove out to a telstra 850mhz tower, put in the telstra sim and tested voice and data, i got hsdpa data and successful call.

How do i know which towers and carriers support which frequencies? I have previously checked with a nokia 6120 classic (850/2100) and a nokia n900 (900/1700/2100), if the tower works on the 6120 but not the n900 its 850mhz, if it works on both its 2100mhz and if it works only on the n900 is 900mhz

Why did i not change the bands in engineering mode? because thats a good way to brick your phone if you don't have a radio to flash back if something goes wrong.
[Android General] m0tyrider:
Can you please check it with the engineer menu? Your tests are not accurate....just because you are near a tower does not mean your phone will connect to it, specially if we all don't 100% know that the phone is compatible with these bands.

You may still have been in good range of a 2100mhz tower totally defeating your tests
[Android General] bgdwiepp:
I brought a bk precision handheld spectrum analyser to check what frequencies were being used. Don't worry, i checked output power on the unspecified band too (850mhz CLR), and they're well within ACMA limits.
[Android General] m0tyrider:
Oh nice :)

I am looking at a Chinese phone that will do the bands here in aus, wanting something that won't break the bank :)

How are you finding it so far?
[Android General] bgdwiepp:
Great, I actually had my doubts about build quality and durability so i bought two, and you know, if one was bad, surely there'd be enough parts between both of them to actually get a working phone.

But everything turned out well, I can't really think of anything to complain about with it, one thing that did strike me as odd though, is that when you plug in the USB cable to charge it it can click into place but be slightly at an angle, doesn't matter, still charges , doesn't seem to damage the socket or anything, and you can straighten it up too, just a little odd.

I'll probably send the other one to a friend who has an ancient iphone 3g.
[Android General] Animal_Chin:
Would love to know whether 1900 does work on 3g because AT&T's 3g here in the states runs on 850mhz and 1900 mhz.

As of right now that's the last chance I know of getting this phone to run on 3g here in the the US.

You say they are shown being enable in the engineering menu. So you think that gives it a pretty good chance of working?

I'm debating on whether or not to spend the money on another sim card. After reading your post and coming somewhat close to starting to understand all the network lingo, I'm leaning toward taking the plunge.
[Android General] bgdwiepp:
Unfortunately, australia has no networks that operate on the 1900mhz band, however, I DID just play around with the engineering menu for band selection, it does appear to work correctly, my house sits in the middle of a 2100mhz optus tower and an 850mhz telstra tower, so after disabling the 2100mhz band, and restarting the phone, the phone would no longer work on the 2100mhz band, the same with the 850mhz band. This implies that the menu works, and thus the 1900mhz being enabled works. However, i can offer no field tests or guarantees.

Also, yes, the band selection does work, however, I wouldn't play with it, if something goes wrong you're very very unlikely to find a radio image let alone a repair centre for this phone. By default everything is enabled so there is no need to fiddle around with it.

Bluetooth headset+incoming call: unusable

I bought a UMI X2 (2/32-version), but I have some big issues with that. All are connecting to the bluetooth. I have a Sony Smartwatch and I can't connect to with Umi. I can find and pair they together but one second later, the Umi and/or Smartwatch lose the pairing. So, I have to start again the pairing. And lose again, starting again,...etc. Same story with my notebook also. In this case, I can pair together but only as audio device (headset). No possible COM port connection. It would be necessary for MyPhoneExplorer to sync the MS Outlook calendar meetings with my phone. But without a living COM port it is impossible. The third big issue also coming from bluetooth. I have a BT headset (Sony MW600). If I use the headset, every incoming call will be terminated after one second. The phone write after that: RADIO OFF. And the status of cell phone singal strength will be also zero with a "denied" symbol in the edge of status bars. If i make an outgoing with headset, it is possible but after the call with a terrible sound quality, the signal strength will be here also zero with a "denied" symbol. And searching for mobile signal. I use the X2 only with one SIM card.

Please help me, what can I do?

[Android General] Jose_dias:
got mine. great screen and performance
[Android General] gelisob:
alternative?

Have been playing around with my X2 for some time now and beginning to doubt in the point of having 5" 1080p screen.

Can anyone tell equal quality and features phone with just one difference, 720p screen? from personal experience perferabily.

I believe same hardware with 720p screen would perform even better and have better battery life and i will not really notice the picture difference.

Same cpu, 2gb ram 32gb rom etc would be nice..
[Android General] bgdwiepp:
Ok, while the difference certainly isnt as huge as from 960x540 or 800x480 -> 720p, there is still a difference, you spot it on high resolution icons and on text heavy webpages, but aside from that there isn't much in it.

In direct comparison to my now year old HTC One X screen, the blacks aren't as dark, eg, the contrast is a bit worse, but the colours are far more accurate. The resolution doesn't make much of a difference but i would prefer have it than not. However, I don't find it hinders battery life or performance at all, the battery life and how snappily the phone works seems to be equal or better than my one X - sure the one x is a year old but it was a flagship, not a midrange like this one.

Battery life relating to the display isn't going to change much, because with the higher res screen comes a bigger display, and with the bigger display comes more room inside the phone for a bigger battery. That said, there is the Jiayu G4, which has a massive battery and a smaller screen, at the expense of a thicker phone. Performance wise, there isn't much difference at all though.

Is the right capacitive button a "Menu" or "Multitask" button?

I'm aware that the slickscreen will suggest it to be Multitask, but just wanted to confirm with actual owners of this phone. :D
[Android General] MarvinFS:
the link is dead please correct!
[Android General] S4X:
Found on the net that some other phone with similar bands gets 2 MB/s on AT&T network with Straight Talk
[Android General] MarvinFS:
Analyzing kernel it's obvious that these T (or turbo) versions are just a Chinese marketing.... it's a simple overclocked from the default 1.2Ghz.

Anyone can implement a recovery script for controlling the freq?

as by the sources there are a possibility for 1.7Ghz... i guess soon we will see the TT version of this phone! :)

[Android General] Animal_Chin:
I went ahead and got one of the ATT straight talk sim cards and tested it out Friday. So far I haven't been able to connect to 3g. I tried a few spots that should have been 3g areas. I'll be in a different part of town tomorrow and test again.

That one says 3g 850/2100

The umi x2 only says 3g 2100
[Android General] vasilis266:
https://github.com/varunchitre15/MT6589_kernel_source
[Android General] S4X:
Is this what manual says? All sites tell that two 850 and 2100 are 3G, like this one :

http://www.umitablets.com/umi-x2-sm...k6589-quad-core-android-4-2-1g-16g-white.html
[Android General] Animal_Chin:
Sorry, Umi's website states 900/2100 for 3g. Merimobils quotes them. Pandawill says 850/2100 just like the website you mentioned.

Still wasn't able to get a 3g signal. Had full bars 2g signal.... Checked at two more areas today.

I think you really need both 850 and 1900 on 3g to get decent speeds on Att's network.

I can't say that this phones don't have these bands but It doesn't seem like they do to me.

I'm interested to hear if anyone has any better luck than me.

charging

Tell me about your umi X2 charging behaviour..

Mine charges STUPENDIOUSLY slow. before posting i did a test, it was @ 53%, plugged onto wall charger it came with and checked back in an hour, 83%, so like 30%/h rate on wall charger, and i know that 90%+ goes slower etc.

It's a lot worse on common computer usb port, i've gained like 10% in hour, and nothing is really running on it.

My Iphone 5 gets from emtpy to full on wall like in 2h time.. how does Your umi charge up?

I've tried with iphone 5 wall charger too, same thing. (iirc umi charger has 1 amp written on it and apple one 1.5 amp)

Never mind the wall charger amperage, it clearly doesnt use it's potential anyway. Do i have faulty charging circuit (resistors?) on my phone or do others have similar issue?

Serious bug in UMI X2

I found a serious bug in UMI X2 (firmware 20130625 by UMI).

External SD-card is mounted as /storage/sdcard0 (and following symlinks /mnt/sdcard and /sdcard).

Internal storage is mounted as as /storage/sdcard1 (and following symlink /mnt/sdcard2).

And at the same time system names storages correctly: internal storage has name "Phone storage" and SD has name "SD-Card".

This situation is not normal because:

1) Many apps "think" that /mnt/sdcard is the internal storage and store their data on it, but in fact they store data on external SD.

2) "Moved to SD" apps are stored on the low-speed external card instead of high-speed internal storage (and disappear when we eject SD).

But if we start the phone without external SD, then internal storage is mounted as /storage/sdcard0, and "moved to SD" apps are stored on it.

I tried to edit vold.fstab file with well-known method for storage exchange. But the result was the following:

1) SD was named as "Phone Storage" and internal storage was named as "SD Card".

2) "Moved" apps was stored anyway on physical SD.

In other words - this experience was failed.

May be anybody know how it is possible to fix this bug?
[Android General] Animal_Chin:
Bricked Umi x2

I was using an app to move a batch of apps to sd and it must have tried to move some system files because the phone locked up.

It would not boot back up.

Gets stuck after splash screen.

Tried using the stock recovery wipe and reset but it doesn't seem to do anything.

Tried sideloading a custom rom using adb but after it sends the file the phone tried to install it and then says something like install aborted.

Tried using adb to push the custom images I've found to the internal sd card but I always get some kind of error message, sometimes the error is "access denied"

Tried mounting the sdcard as I thought that might be the problem but it always fails.

Does anyone know of another method to recover this? I'm out of ideas at the moment.

There doesn't seem to be any all in one custom rom loaders out there. Maybe someone can post it if they of of one.

[Android General] bgdwiepp:
I did this exact same thing when I first got my UMI X2, I used Shuame(its all in chinese so beware) to put a custom recovery on it (i did it while it was stuck just after the splashscreen), then I put the custom rom on a microsd and flashed it from the recovery.

Let this be a lesson to always do a nandroid first!

This was in the first release as well, not just the recent rom/update
[Android General] bgdwiepp:
This might be useful to new users;

To install a custom recovery, it is easiest if you're already rooted.

1) Download Mobileuncle Tools from the Play Store

2) Download the custom recovery here, put it somewhere you can remember easily, probably /sdcard/.

3) Open the Mobileuncle Tools, grant root privileges, select "Recovery Update".

4) Choose the recovery.img file and viola.

Ok, so something i noticed is the recovery backups don't always backup the /data partition, you should make sure you do a full user app+data backup with titanium backup if your recovery won't do the /data partition.

Here is a link to the latest UMI X2 rom. I don't have a changelog unfortunately though. You will probably have to format /system and /cache before you flash for it to not get stuck in a bootloop.

I *think* this rom is a slightly earlier version of the above one, maybe a few days, but it doesn't download properly for me.

And finally, if you lose root on your device but can still access the recovery, just flash this and you'll get it back - alternatively you can use it to change root management programs too.

Incoming voice call impossible with BT headset

Hi,

as I wrote some days before, I have a serious issues with the blutetooth. I tried the newest rom (25.06.2013) and the question with that was a little bit clearer.

So, if I allowe the data connection and use my BT headset, the incoming call terminate immediately. Without a data connection, the calling is running without any issue. I use only with one sim.

Pease help me to solve that issue. I think it is not the normal way.

Audio System: Dolby Mobile Sound Is it true?

what is the sound quality of this phone? I had bought zopo c2 which alleges hi-fi quality yamaha audio 1 month ago but the sound was very very bad both music sound and handset I sold it immediatly I have already used jiayu g3.The sound quality was very well.Is umi x2 as good as jiayu g3?
[Android General] bgdwiepp:
Ok, a few more things;

Check your system apps for the com.android.caivs.app or just caivs.apk - this is a app used amongst chinese manufacturers and is generally bad (sends sms sometimes), it's advisable to delete.

Do you need to follow the steps to install official UMI rom?

Maybe, the if the rom is signed, it will install from stock recovery, if it isn't, you need custom recovery.

As far as restoring your phone by shuame, it's a bit tricky as the program is in chinese, and I have since uninstalled it, since i no longer needed it so i can't do screenshots. Basically, you connect the phone, with the program running, it will detect the phone and maybe push an apk to it. Then you will be able to choose to flash a rom from the first tab, choose the rom to flash (the one with the yellow gerbra wallpaper i think). It will prompt you then download the rom and recovery and install them, you may need to click some buttons or reboot the phone or something during this step. After that the phone will be useable. If this doesn't work here is a screenshot, from shuame showing the install recovery and reboot recovery button.

Sound quality, earphones is good, not great but good, make sure you don't turn on the enhance audio that makes it sounds baaaaad, speaker is surprisingly loud and clear. Call quality is acceptable.
[Android General] xwing-s:

Turbo Version

Hi there, does this rom support the "turbo" version? I'm hoping that the rom fixes my GPS issue and offers some performance improvements. I've rooted and modded some samsung's but i find flashing this a bit risky since there aren't many choices available. I prefer pure vanilla android. but it seems the LEWA os has been receiving some good reviews. Any suggestions? Will their update be available OTA?

i flashed the latest official beta from needrom.com this works for my umi x2 turbo. It will keep your clock at 1.5ghz,

GPS antenna is moderate. But the time for finding a lock depends highly on the reference location(last known location), I think the agps is not well implemented.

With good reference lock takes seconds, else 5-10min

I really like this phone, lives up to me expectations especially the speed and response is almost instant.
[Android General] CodexRobin:

any improvements to performance? Is it worth the update? or should i just wait for official ones from UMI themselves.

UMI x2 Turbo

G'day

I am very interested in the latest version i.e. UMI X2 TURBO(Newer Overclocked CPU @1.5Ghz)to use in Australia with the mobile carrier

Amaysim which uses OPTUS (3G 900/2100)

BUT 99% of the websites I visited all state 3G WDCMA 850/2100 with the exception or redtabletpc.com stating 900/2100

so its very misleading and frustrating to get accurate information that redtablet site also states OS is Jelly Bean 4.1 which is incorrect

Where did you buy from?and how much did you pay?

Please advise
[Android General] CodexRobin:
Mine is 900/2100 and i'm from malaysia. Works with all 3 major operators in malaysia. 3g and HSDPA.

Does your UMI X2 Turbo perform as expected?
[Android General] bgdwiepp:
There are two "different" models, one that says it supports 850/2100 and one that says it supports 900/2100 however, for me, my 900/2100 also supports 850 so they're probably the same and they both support both; who knows.
[Android General] sunsen:
Please tell me where you bought the 3G WCDMA 900/2100 model from?

G'day bgdwiepp,

I too use OPTUS (Actually Amaysim) and most of the time on the Gold Coast /regional QLD....so I need 900/2100 and wish to BUY the newer UMI X2 Turbo version

I seek reliable first hand confirmation that this UMI X2 Turbo works on 3G WCDMA 900/2100 BEFORE I purchase and would really appreciate some feedback.

BTW besides phone calls what is the data speed rate like?

It’s interesting that you say there are TWO Models

Please tell me where you bought the 3G WCDMA 900/2100 model from?

Was it by fluke you received the 900/2100 model as I have been searching high and low for the past few weeks to obtain accurate confirmation from sellers. So far only Redtablet PC ($319) and Merimobile ($288 is PRE ORDER = 2G RAM & 32 ROM what is weird the 1G RAM & 16ROM version is dearer @A$303 )state 900/2100 specs

Literally just yesterday I received an email from merimobile

Confirming that the model they sell does support 900/2100 which is corroborated in the review video including the specs in the Chinese manual.

Their price is $288 and supposedly in Stock early next week (as confirmed by a subsequent email)

As you too have noticed most websites state either just 2100 or 850/2100 for 3G WCDMA

I joined Giz China even their test state 850/2100

NB I cannot provide links as I am a new member

This morning Giz China have a $20 OFF special for readers from Antelife BUT this is the 850/2100 model

I quick final novice Question (sorry if this has already been covered) But in regard to dual SIM slots,

am I to understand that only one of the SIM slots support 3G both 900 & 2100?

While the other SIM slot is for 2G GSM only.

What IF I am in a remote area with NO 3G in that instance do I have to manually swop over to the GSM slot

OR

Does one SIM Slot support Both 2G GSM & 3G 900/2100 and automatically connects to whatever frequency is in range

BTW

HOW were you able to gain 850/2100 connectivity was that thru the menu settings or did it just automatically connect assuming you tried a Telstra/Vodaphone/boost SIM card

THANKS in advance for any advice or feedback

Cheers
