When we are looking for smartphone to buy, what matters to us is specs. But one of the specs that is usually less important to us is battery. To be honest, battery is the most important specs in a smartphone. In the last two months, I have used One plus one, Jiayu s3, Ecoo e04 and have just ordered for Umi emax. Jiayu S3 has one of the worst battery in a mobile phone. While Jiayu s3 is a good phone, but it has a terrible battery. It takes about 4 - 5 hours for full charge and also last approximately the same time on a full charge. The screen is not very sharp, as well as the camera. But the phone is fast when browsing and watching videos without a single lag. I personally will choose ECOO EO4 over Jiayu s3. I have used both.

a7yler,

Always great reviews and Gruß aus Schweden. What I missed in your reviews where the quality of the GPS. Also how do you find the call quality?

I used to have the good old UMI X1 which was released years ago (I think 4 years) and my wife enjoyed it until a couple of months ago when I smashed her screen by mistake.

Oh well, so I started looking for a replacement and this time for myself since my wife got her fathers iPhone 5S. I accidentally stumbled over this UMI and was happy that you have reviewed it.

I'm not a young man anymore (soon to be 49) so I really don't need a superduper what not telephone but what I need is a phone that has a good/great voice call quality and a very good GPS that won't take such a long time to lock. Occasionally I snap a picture or two of my cats and maybe a short video, my wife's a photographer so the good quality photo's I get from her :) And looking at you picture samples and video I must say they look very good indeed.

There you go, so what I would appreciate is if you feel that this phone has a good voice quality and a good GPS.

Oh, forgot to ask, how long is the charge time for a full charge?

Best Regards

Kurt

How to change the battery if there is a need for a new battery?

Is there any protection for the screen?
[Device Reviews and Information] Dare Hood:
The battery is non-removable. You can't change it easily. At least not so easy as removable ones. So far I'm not aware of battery replacements out there for this brand new model. Maybe there won't be such. If the battery is OK and you charge it correctly there shouldn't be a problem. On the other hand you could always use the phone for a year and sell it.

There isn't Gorilla glass protection so you could use tempered glass protecting film. It costs 7-8 $

Can you pls explain this about fdd band 20 and gps
[Device Reviews and Information] Dare Hood:
Yeah, you are probably right if you had all of those in your hands. Sorry to hear about Jiayu S3. Thought it is good quality phone. It's good that I didn't buy it when it pop up on the market. Now I'm waiting for my UMI Emax and hoping that it won't disappoint me (much).:laugh: Meanwhile I've tried to catch Elephone P7000 on Wednesday flash sales but couldn't. Still trying. Something is messed up with these flash sales but this is another topic.
[Device Reviews and Information] KURT.Beadles:
As I understand it will not support the 800 MHz which, if true, will be serious because this frequency is used by most companies in Europe for 4G. Of course there are other frequencies but those are mainly used if you live in a large city. So if you travel a lot between cities or live a bit from a larger city you will not have 4G support only 3g and 2g. Please correct me if I'm wrong but that would be the case in Sweden at least .

Personally I don't use 4G myself but this is really bad news for those who do and it's even more serious that they do specify it in all shops that this phone support this band which it actually doesn't. UMI really did a huge mistake on this one.
[Device Reviews and Information] El greco:
I believe it's something about the firmware. Those last frequencies are not advised and present, while the 800 advised and not present. Definitely something wrong (maybe in the baseband)
[Device Reviews and Information] KURT.Beadles:
So you think that this will be addressed in the next update?

I still haven't gotten an answer if the voice call quality is good and if GPS locks within reasonable time. Could anyone shed some light on this matter?
[Device Reviews and Information] Tautologica:
http://umidigi.com/products/umiemax_specs.html

States:

FDD 1800/2100/2600

I think they have updated those specs since last time i checked.

Pretty sure it used to say: 4G: FDD LTE 800/1800/2600MH

And pandawill etc have updated their specs as well.

800Mhz 4G is nowhere to be found anymore in the spec sections.
[Device Reviews and Information] El greco:
well, I'm living well with OPO without this frequency and I don't think i'll miss it with emax as well... considering 4g with this band here is weaker than 3g, it's only a waste of battery were I live!
[Device Reviews and Information] Tautologica:
It isn't a deal breaker for me either albeit 800Mhz is the band with most coverage in 4G network in my country.

But I think it is still bad PR from UMI to change specs after they have started selling the phone. Ppl might get upset.
[Device Reviews and Information] thewell:
Not a 4g user, but I would be upset in principle, mainly because I would be concerned about what else they may have lied about. If everything else is genuine, I think it would still be good value.
[Device Reviews and Information] Tautologica:
My concerns as well. Hope there aren't any new surprises or I will cancel my order.

Stock ROM SPFlashtool

Hi [MENTION=2105197]s7yler[/MENTION]

Do you happen to have the stock rom bro for the emax.

SPFlashtool version would cool???
[Device Reviews and Information] l1ghtmare:
Geekbench battery results.

Hi s7yler, what do those test results mean on Geekbench 3 please? and did you run the test with all background apps plus ervices (bluetooth, WiFi, gps etc) turned off or the phone as normal with some services you regularly use switched on etc?

I ask as I received my phone the other day and am a little concerned about the battery life. The first day was impressive, I abused the internet on wiFi ,played some intensive games and was impressed that the phone lasted over 8 hrs where my old THL T11 would have died the death several hours prior to that, but today it went from 100% to 70% in less than two hours. Would you say that I am charging it incorrectly and just need to run rootjoy and calibrate the battery or is it a case of a problem from Umi's side similar to the Hammer with less of a battery than advertised? If so I would wager that that would be it for this phone as it is its' major selling point.

Thanks in advance for your help.
[Device Reviews and Information] KURT.Beadles:
Forget receiving any answers from s7tyler as he's never in this forum.
[Device Reviews and Information] l1ghtmare:
Really? Shame. Well do you think I should turn off all apps and put my phone in flight mode before running geekbench 3?
[Device Reviews and Information] KURT.Beadles:
I wish I had a good solution for you but all is unfortunately trial and error about Chinese phones. Haven't bought the phone since I figured it's a very small community for it and people like s7tyler are normally good at reviewing a phone and all seems nice and dandy but when you actually get the phone that’s a different story. So I'm always pretty sceptical to those reviews, since as I wrote earlier the support is very often close to none from the reviewers. There are of course exceptions to the rule. Some of the Chinese phones have a lively based forums like the Jiayu S3, but that phone seems to have it's own problems.

We'll have to wait and see how the support for UMI picks up.
[Device Reviews and Information] s7yler:
I'm in the forum but I get like 100 questions and mails EVERY single day from people about everything! (in more than 20 forums on youtube and email) I can't give every person answers and support - I simply don't have the time - I have a job, family and other things besides this. Alone today I got 30 mails from people who want me to suggest what phone they should buy for 150 USD, I can't answer that - because it depends on your needs! everyone have different needs on a phone. There is no perfect phone!

If you looked in my Youtube videos comment section, you would know that I actually try to answer peoples questions. But it also takes a lot of time.

I review the phones and try to show them for the people. In EVERY review I try to tell about the pros but ALSO the cons and how I see it. Because as told no phone is perfect. But I review them from my perspective. What people want to believe or get is their free choice. I don't really recommend one brand over another.
[Device Reviews and Information] s7yler:
Geekbench 3 is measuring the performance and on screen time of a device. So it will actually load the phone, and simulate as were it in use.

I run the tests without anything loaded in the background and everything else turned off. Because the app will as told heavy load the phone in the test, you can also leave it all on, then the score may be a little higher for you, but the on-screen time score will maybe be shorter. But I do it that way.

Just try to do your own test, for example one where you turn everything off, and one where you have everything on. I sometimes do 2-4 tests on my devices to be sure. And yeah it sure takes a hell of a time to do.

The on screen time and the score can be compared with a car. The time is how long it will take and the score is how fast it drives. So one can for example drive 100 km in 2 hours with speed 200 km/t. while another drives the 100 km in 4 hours but only with speed 100 km/t. So one may have better on-screen time but only because the performance of that one is also the half.

If it goes from 100 to 70% fast there can be MANY reasons for that. Maybe you have apps in the background that drains the battery, maybe you had the GPS or BT turned on, and the GPS were working all the time? maybe the battery needs calibration? I can't answer you on that. I have only experienced good battery life on the eMax, and I have seen a lot of other china devices that do a lot worse.

Sorry I don't have the stock ROM.

HI,

I wanted to ask you is this phone worth buying?

WHat is a better option in the same price range?

Thanks
[Device Reviews and Information] s7yler:
The GPS was not included in the review video, because I have a separate video for the GPS, where I test the GPS live in a car with navigation. Also in post #1. Generally the GPS is good and ok for navigation. The fix is from 15-40 seconds for me, depending on the sky.

Call quality is in my opinion fine, no problems with that. I hear people fine and they hear me. The charging time, I am unsure about - but it seems not to charge quick, rather normal charging time I would say.

And btw. if you want me to see post/questions you MUST quote my name/write my name correct - you wrote "a7yler", else I don't get notified. I only coincidentally saw the questions. XDA only sends me a notification IF people write [MENTION=2105197]s7yler[/MENTION] or quote my text that includes my name.
[Device Reviews and Information] s7yler:
I would say yes, but have a look at the pros & cons in the review video, and see if they fullfill your personal needs.

You have to take that decision yourself, as people have different requirements/needs.

Is it safe/wise to use a 2A charger for this phone instead of the 1A that comes with the package?
[Device Reviews and Information] SamBaws:
I'd use any major brands OEM charger instead of the one that comes supplied. I'm not saying it's a fact, but it might be cheap parts inside the charger which can have ripples/spikes.

Using a 2A charger is no problem as long as it (the phone) doesn't overheats too much.
[Device Reviews and Information] s7yler:
You can use nearly any. It doesn't matter if the charger is 2A, 3A or 4A.... it is not the charger who determines the power, it is the device. For instance if a 3A charger is connected to a device that only allows 1A, the device will only pull 1A out of the 3A charger. It is the same with a laptop and other devices. It is the device who is in control NOT the charger connected!
[Device Reviews and Information] anchal joshi:
At least we can travel long distances with this smartphone.

Newly launched Sony Xperia Z3+ also has huge battery. It is also very useful in long distance travels.
[Device Reviews and Information] Tautologica:
In a russian forum (with google translate) someone mentioned that the eMax only takes in 0.9A so i guess using a 2A charger is of no use.
[Device Reviews and Information] Tautologica:
Few notes so far about the eMax:

Some spanish guy opened the cover of the eMax to check the battery and there is TCL 3500mAh battery inside

(picture here):

http://www.htcmania.com/showthread.php?t=1021488

The Russians did some experiments and i suppose atm they think that the battery is something like 3300mAh.

I got the phone 2 days ago and so far the battery has not been anything special imo. I've charged it couple of times already but the Battery stats won't reset so I can't really tell for sure how much screen time I've gotten out of it. During night (8h) battery level has gone down at least 10% so far. Anyway, I would expect the battery to show its true potential after few more charges and if it doesn't, I will try battery calibration and install some batterystats app. And if the battery stats won't start to reset I suppose I have to try to reset the phone to factory defaults, or I'll wait for some new rom update.

Few times I in the first try I got some ghost touches (like someone in meth was using the phone with out me touching it) but after few reboots I haven't got those anymore.

Auto-brightness kinda sucks. It changes too often and most of the time in auto mode it is darker than what it would be if I set it to the lowest possible setting from the display options. Btw if the phone crashes when entering the display options (mine did not), one should reset the phone and it should allow to enter display options in the settings.

Bluetooth range/power might be a bit weak in the eMax but I have to run some more tests to be sure it is the Emax and not my BT-speaker. With my old phone I was able to keep certain distance withe phone and speaker and with emax I had to bring the devices closer to each other to be able to continue listening music. But this was just a one time test so could be something else. Just mentioning it if someone else has similar experiences.

Image quality of the cameras are not good. The part of the image that is not focused is blurry as hell. But it was expected that Umi had to save somewhere and camera is one of those.

Xposed framework can not be installed to eMax atm. More info here in spanish:

http://www.htcmania.com/showthread.php?t=1031390

I did not understand completely what was said there but it has something to do with odex/deodex of some .jar/jex files or something like that. Tbh i never got around to really study the odex and whatnot stuff ppl mention with custom roms.

Ipega pg-9017 BT-controller does not work in gamepad mode with eMax. But I suppose it is more because of Mediatek soc than eMax's fault.

I pretty much just listed the downsides that I have come up so far but still I am quite happy with the phone. At least for the flash sale price it is worth every cent so far. It is light but still big screen with good quality (although screen could be brighter when using the phone under sun) and fast as hell. GPS has locked really fast so far.

My 2 cents.
[Device Reviews and Information] SamBaws:
I had the same problem when the language option was set to Norwegian. It was fixed by changing language to English, and back again when finished. After a day of usage the problem was gone.

Also, proper cases (unlike the "universal" ones that uses adhesive to stick to the phone) and tempered glass protectors are finally showing up on AliExpress and Ebay. I can't post links yet, but recommend getting them off AliExpress as the prices are cheaper. At the time of writing there is just a clear TPU case and a glass protector to be found.
[Device Reviews and Information] Tautologica:
I had my language as English from the get go. I wonder if those Spaniards changed their phone language to castellano and it was the cause of the problem. Anyway, hopefully we will see some custom roms shortly that work. I think the russians at http://4pda.ru/forum/index.php?showtopic=661358 said that at least the Miui custom rom from rootjoy is bugged so that 2nd SIM doesn't work and some other stuff as well.

About the accessories, check this link:

http://www.movilesdualsim.com/tema/umi-no-regala-accesorios-para-umi-emax-solucion.104640/

It seems TCL 3N M2M and M2U and M2L accessories should fit eMax and are a bit cheaper and more abundant than eMAx stuff.

My eMax came with some glass protector installed already. I did not order any such thing...
[Device Reviews and Information] tracktriathlon:
I've got the same problems, namely ghost touches (the phone thinks I've touch somewhere else on the screen, most noticable when typing text in a text field) and going into Settings -> Display makes settings crash. Camera quality is average for such a phone as I find the pictures grainy,no matter what settings I try (the 9.5M one so no interpolation hopefully)

I really like the phone, big screeen and big enough battery at a really good price but it's disappointing to see the lack of 4G compatible frequency in the UK (this claim has now been removed from UMI's marketing pages but they still have lollipop support when the ROM doesn't yet exist). Hope that a software/firmware upgrade can sort the above, then it would really be an amazing phone.
[Device Reviews and Information] keiner.da:
Same situation here with my UMI eMax, but I have success with this working solution without reset the phone (or use external tool like rootjoy):

Install an app like Any Screen Timeout (or similar app)

Start this app and set any value for sreen timeout, e.g. 5 minutes.

Close and restart the app, same value should be shown.

Go into settings – display : should be working now!!!

The installed app (see 1.) can now be removed…the trick is done. :good:

The unavalaible setting Screen Timeout was set.

(therefore activity "display settings" stopps with an exception and was closed by android).
[Device Reviews and Information] xdatin1:
Which launcher would be good for emax?

The one that comes with it is not too many functions for adjustment.

Is there any ROM that is better than this which comes pre-installed?

The charger that comes in the package does not seem safe. When I plugged it into the socket of charger could be heard buzzing.

Display settings works ok only if I set language to English(US).
[Device Reviews and Information] Tautologica:
I recommend Nova Launcher. I use it in all my android products. The free version is great and u can modify it a lot.

I haven't even used the charger that came with eMax. I use an old Nokia 1A charger and it takes 4h to get eMax from 0% to 100%.

This is the latest KitKat version in the rootjoy.

UMI eMAX KitKat 0619 https://yadi.sk/d/tutqgPkohZvR2

I have not idea if it is good or bad, nor what is the change log etc...

There are other roms in rootjoy as well but I havent seen any good comments about them.

I am waiting a community made custom rom or official Lollipop from UMI.
[Device Reviews and Information] steve0b1:
So far so good with the Umi Emax, had for a week now although not using frequently as I'm still waiting for my case.....:rolleyes:

First thoughts:

All pretty good, GPS spot on, display/speed/sound all ok, camera a little disappointing but works ok-ish. I'm upgrading from a THL T11 so I'm used to a fairly poor camera :D

Does anybody know if there is a reset button on the phone? Have a small hole above the camera but not sure what this is? Had a few blank screens from time to time on my THL but just removing the battery and refitting it sorted it out!! Obviously can't do this with the Emax?

Also have rootjoy downloaded but not really had much experience with flashing/changing ROM's!!! I have also not really heard of any good ROM's as yet on rootjoy has anyone tried any out?

I have read that the new version of KITKAT improves the camera is this true? Has anyone tried this ROM out and noticed any differences? Also is it available in rootjoy or does it need to be done manually?

Thanks
[Device Reviews and Information] Chickens83:
The Russians say the Kitkat update has changes to the camera, ie clearer or sharper depending on the online translator.

Iv been using my emax in the UK for 4 weeks and the 4G coverage seems pretty good. (dont have anything to compare to sadly.)

About support:

The data cable came faulty out of the box. Send them an email, they asked for a pic, send them the pic, they haven't answered yet. (emaild them again will report back what happens.)

if anybody used any of the different roms any info would be appreciated, considering to try the new kitkat version in rootjoy (also will report back if i do so)

I read about you can build custom roms if you got the device tree and such things but im a complete android noob. If anyone can point me to a direction towards that, that be great.
[Device Reviews and Information] thewell:
Hi, what 4G frequency are you using, thought we had lucked out with the band 20 omission?

FWIW, I haven't encountered any of the issues some people have been reporting-ghost touches, white spots etc.

Seems a bit strange there is no way to clear tasks with one click, have to do it one by one (unless I am missing something) I think the audio is ok, but I don't tend to use just a speaker. And the camera is better than I expected after the reviews.

And if Umi is selling the Iron with 5.1 , surely there must be the chance of lollipop for emax.
