hi guys, how can i flash lollipop?
[Device Reviews and Information] cotavean:
Hello!

I won an UMI Emax at the giveaway UMI and its partners organized 2 month ago.

My UMI EMAX arrived 2 weeks ago.

Everything was ok, no problems detected at first. It is working smooth, fast, display is great, performance - WOW!

I made some videos, but I am not allowed to put any, because of the "new users prevented from posting outside links"

----------------------------

After 2 days of use (almost didn't use it) I encountered a problem, the phone was not charging.

First day I charged for 15 minutes, and it was ok, except the charger was a little bit hot.

2nd day started charging ok, then when I checked in 5 minutes - it was not charging. I detected that the cable was not working :( I also tried the cable on computer and it also didn't work.

After 10 minutes of charging with another cable, the UMI charger was hot, and the metal part of the cable was very hot, so I stopped using the charger.

I suspect that because the charger was hot - the cable got damaged. This maybe a 1 time problem, but also can be a problem many people encounter.

I fixed the cable - it is working at the moment.

I am a noob at smartphones, but I learn quickly :)
[Device Reviews and Information] Chickens83:
I've read atleast 2 guys say that they didn't use the charger because it emits some unwanted sound when you plug it in.

About RootJoy: When I do a backup of my apps, does it also store the settings of that app? I looked in the backup folder, but could only find the APK files. This would mean I would have to reconfigure all my apps if I do a restore after flashing a new ROM?
[Device Reviews and Information] cotavean:
no sound, just it gets very hot in no time. so I use a 0.7A Samsung charger
[Device Reviews and Information] Chickens83:
My eMax is still stuck in Customs but when I receive it, the first thing I might do is throw away the charger.

Also

Anyone tried the different ROMs? Some Italians say the JYUI 0629 ROM gives better photos once you put the ISO on 200.
[Device Reviews and Information] dutchguy:
I have not tried an other ROM since I am looking for a good way to backup and restore all my apps including settings. What is the easiest way to do this?
[Device Reviews and Information] Tautologica:
I use titanium backup to backup apps and app-data. Rootjoy only backups apps and not data.

First custom rom made by a spanish user:

http://www.movilesdualsim.com/tema/...kat-4-4-4-v04-19-6-15-por-manowaracero.106572

Xposed Framework works with that one.
[Device Reviews and Information] dragon2knight:
Thanks for the link, installed it this morning, using it all day and no errors. Works really well :)
[Device Reviews and Information] tracktriathlon:
Where is the GPS?

I can't find the GPS on this phone. Can someone tell me where to enable/disable it from? I've got the original stock ROM.

Update on the charger

: The European one which I tested in spain and france works fine. I also got a UK one included but haven't tried it yet. I've used some of my older phone chargers in the UK like a 1 amps HTC or another 1 amps Nexus 7 and worked fine with charging the Emax. I guess that any 1 amps charger will deliver enough power to charge it.

Update on the ghost touches

: After two or three days, it stopped mistyping so I guess problem fixed which is strange as still on the stock ROM.

Camera

: very bad quality pictures, even when as low as 4MP. Very grainy. Does the Spanish ROM solve the camera problem?

4G in the UK

: I've just moved my TMobile account to EE so got 4G for the first time and can confirm that it works with the Emax with EE. I couldn't tell the difference with WiFi when looking at a youtube video, very impressive speed. Did a speed test and got 6MB download and 3MB upload (not fast by 4G standard but that's what I got in Newton Abbot in Devon :) It could well be that I've now got the max 3G speed! though the signal icon said 4G) .

This is from an EE forum to compare with the 800MHz frequency that's unavailable on the Emax:

Thanks
[Device Reviews and Information] Tautologica:
GPS: Settings--> Location, or I just use a widget called Power control, or use the notification tile for gps (two finger drag from status bar).

About the camera: the spanish rom does not make it better.
[Device Reviews and Information] dragon2knight:
I honestly think the camera is a lost cause on this one, it's just not a good one. If you don't zoom in on your pics much at least it's passable for social media. Guess you can't ask for more on such a low cost phone. Honestly, if you were expecting a great camera for $150.00 or less bucks, you were deluding yourself. Truth.
[Device Reviews and Information] thewell:
There is at least one other guy in the umi forum who is in the same boat as me: no mobile data - am I missing something? Have turned it on in both 'settings' and quick toggles. Get a sim-like shape overlaying the toggle, but no actual connection , and no icon at top of screen . It must work for some of you , because you're using 4g ( still don't understand how you get it in UK without band 20)

And why are the updates only available in rootjoy, what about ota?
[Device Reviews and Information] Tautologica:
Perhaps you have to manually set Access Point Names for your operator? Google APN + [your operator].

I had to do this with my last china phone and woth a different operator. Though I don't live in UK.

There are other 4G bands than 800Mhz as tracktriathlon quoted above. For example in my country there is 1800Mhz band that is working in and near big citys which I can use. Although I opted to use 3G only atm cos 4G signal strength is lousy where I live and use 99% wifi anyways.

About the OTA: Perhaps umi just chose to give updated thru rootjoy. Idk.
[Device Reviews and Information] tracktriathlon:
Thank you. I'm used to the old GPS icon which wasn't called Location.

I understand that a $150 device wouldn't have a great camera (and I didn't buy it for the camera) but I expected it to take "normal" pictures at lower resolutions like 4MP with no zoom, not grainy pictures (HDR doesn't seem to make much difference).

My HTC Desire from 2010, with stock ROM, takes "slightly" better (but smaller resolution) pictures (or certainly comparable ones) so I'm surprised that even a 2015 budget device hasn't improved the quality and wondered if it's only hardware (so no chance of improvement) or if it's software related?

I've lived with the camera bug on the HTC Desire since putting Cyanogen Mod on it so would like to now be able to take "normal" pictures, not the sharpest and greatest contrast.
[Device Reviews and Information] Tautologica:
Well let's see if future roms bring any enhancements to the camera's quality. Atm we just have to make due...

thewell: btw make sure that you have the sim card with 3/4G ability in SIM1 slot. Sim2 slot only supports 2G.
[Device Reviews and Information] dragon2knight:
Oh believe me, most all camera's on China phones $125.00 and above are at least ok, some even pretty good. It's just the one on THIS phone that bites. Software can help to a point, but hardware is also important here. The 8mp Omnivision camera they used here is just awful....and we just have to accept that. The front camera works fine, that proves to me it isn't software, but hardware. I seriously don't care as I use a real camera for even every day shots, as I care very much about the quality of my pics. I use an LG G4 as my main phone, and I don't even consider that camera good enough for me. Of course, everyone is different, but if you value your pics and can't carry around at least a good point and shoot camera, then steer away from cheaper phones and invest in a higher end phone like a G4. That's the only way to be sure your getting a good camera to go with your phone.
[Device Reviews and Information] steve0b1:
Downloaded the JYUI 0629 ROM tonight, all seemed ok although i did experience the keyboard touch issue that many have experienced!! It was like the keyboard was invisible and when you try and type it actually responds to what is under the keyboard if that makes sense? ? Anyway after a re-boot all seems fine now. ROM seems stable with no bugs found yet (although early days) - as for the camera doesn't really change anything (well not noticed any major improvements). I will continue to use over the next few days to see how it go's and hopefully the keyboard/touch issue doesn't re-appear!!!
[Device Reviews and Information] dragon2knight:
I tried this one last week and couldn't get rid of the bug, so I switched to the one from Spain found by [MENTION=4767548]Tautologica[/MENTION]. Never looked back. Very stable, lots of customisation, just easily the best one for the eMax to date. Just trying to save you a lot of time trying to find a stable one :)
[Device Reviews and Information] Chickens83:
They say the camera is better if ISO is 200?
[Device Reviews and Information] dragon2knight:
I'll be damned if I can see a difference at any ISO...maybe a teensie bit sharper? Or not. This isn't a very good camera, unfortunately. Maybe with the Lollipop update it will get better.
[Device Reviews and Information] eberaldo:
I made a video of the ghost touches, send a mail to the support, they said I should recalibrate the touchscreen, how do I do that? I wasn't able to find such an option in service mode.

Umi emax ghost touches: https://youtu.be/aeZ9_aDwGLE
[Device Reviews and Information] Chickens83:
So just received my eMax and I tried JYUI0629 now unfortunately it unrooted the phone and now rootjoy cannot change roms, what to do?

Used Recovery and was able to change roms.
[Device Reviews and Information] Chickens83:
Has anyone tried maxxaudio or viper?
[Device Reviews and Information] steve0b1:
Well a fair few days using JYUI0629 ROM and the ghost touches seems pretty rare to be honest, as far as the camera just a very slight improvement I'd say most likely due to the different software installed on this rom rather than the Android standard software. All seems quite stable and can't complain about the ROM in truth. My only niggle is the battery when in sleep mode, last night (over night) the battery lost 18% in 7 hours when not in use (obviously wifi, gps etc.. all off)..... My THL T11 only lost 2-4% in this time with a smaller battery. This issue maybe down to the ROM? or something installed causing my phone to wake? How has everyone found this phone when in sleep mode? There is a function however in the ROM settings to actually turn the phone off and back on at certain times and this seems to work a charm so this will help in the meantime.......
[Device Reviews and Information] dragon2knight:
This was the first rom I used when I got the phone in, it was ok...thats about it. The one from Spain is the best so far by far, no issues as it's based on the latest stable UMI 4.4.4 rom. You get everything with that one including Xposed and Gravity, it's a customisers dream :) As for the battery draining issue, try out Greenify, it turns off completely all of the apps you tell it to while suspended, and it works like a charm to improve not only battery life, but it also saves tons of data. It's free, works either rooted or not(but you get more options rooted).

Here is the link to that rom, thank [MENTION=4767548]Tautologica[/MENTION] for the heads up:

http://www.movilesdualsim.com/tema/rom-mod-umi-emax-basada-kitkat-4-4-4-v04-19-6-15-por-manowaracero.106572/
[Device Reviews and Information] Tautologica:
I'd say it is the jyui rom. I am using the spanish made kitkat rom that d2k linked above and I think it loses 2-5% battery during nights. Though ofc you can try to troubleshoot with some BetterBatteryStats etc what is causing the power drainage. But I would recommend to just install that manofwaracero's kitkat rom. It has Xposed framework installed (though you have to activate it and the modules you want to use) and with it you can customize the rom even more to your liking with ease. To save even more battery (if that is even necessary with this phone) I use the (xposed module) Gravitybox's Smart radio, which changes to 2G when Wifi is on or phone is in sleep.
[Device Reviews and Information] Chickens83:
My Timmy E82 has an OV8825 8MP interpolated to 13MP and takes 13MP pictures at 4MB while my UMi eMax has an OV8858 (not personally checked) 8MP interpolated to 13MP and takes 13MP pictures at only 2MB. Anyone knows why?

Also I believe that UMi has different suppliers for different parts like Adri_L of htcmania getting a TCL brand 3500mAh battery while Timo of gizchina.de gets an unbranded 3500mAh battery (at 6 months time I'd say Timo's battery would probably have degraded faster than Adri_L's), my concern with this is that they might have problems with optimisation for other parts like the lens or speaker. Although I hope they continue optimising for the possibility of making it a bit better.

Also lollipop at August 18?
[Device Reviews and Information] dragon2knight:
It' s safe to say that all China phone manufacturers source whatever parts they can get their hands on during a particular run, not just UMI doing this. Sadly, the rear camera was never a good one on this phone...but it's the only part that is like this. The battery is fine, as I mentioned on another thread, who cares where it's sourced from, it still works great. You can't expect high end parts on a $150.00 phone, you take what you get and enjoy the power and great display, the excellent battery life, and the great rom support and run with it. Not many phones out there can say that it's this well balanced, and fewer still can do it for such a great price. Now that you've got it in, have fun with it and stop carping about who supplied what and why...in the end it really isn't that important ;)

Oh, and UMI, on their own forum, stated a Lollipop rom by the end of this month(July). Are they being honest about it? Time will tell.....
[Device Reviews and Information] s7yler:
The size of the pictures doesn't really say anything. It could also just be that the camera software in the Timmy isn't so good, and files getting bigger than needed.

None of the devices that the reviewers review at htcmania or Gizchina should be compared with the final product. Many of the devices Gizchina for instance get are pre production versions or engineering samples. They are not always reflecting the final hardware. The UMI Hammer also had another looking battery in Gizchina.coms first review, and that's because they had an early version.
[Device Reviews and Information] steve0b1:
HI All, just wanted to let people know that actually after some tests the phone charges at 1.03A when i use a 2A charger and 0.6A when i use an alternative 1A charger (similar spec to what Umi provide but without getting so hot!) So this concludes that to speed up charging buy a 1.5A+ charger...... there will be a benefit.

Also thanks 'dragon2knight' downloaded Greenify and this does help with the battery when the phone is in sleep mode :D
[Device Reviews and Information] Tautologica:
Now they say that LP will be released during August:

http://community.umidigi.com/forum.php?mod=viewthread&tid=37&extra=page=1&page=2
[Device Reviews and Information] dragon2knight:
Wow, they just pushed that up....hope they do 5.1 as well, 5.0 is a waste of time at this point.
[Device Reviews and Information] Chickens83:
UMi posted this on their facebook page yesterday, it says August 18, although they're not sure if 5.0 or 5.1.

[IMG="UmiOfficial facebook page"]http://i.imgur.com/8XjvUy7.jpg[/IMG]

I know it's just me but I like how the engineers working on the eMax are wearing cowboy hats.
[Device Reviews and Information] TrackTriathlon Progress:
I've installed the Spanish Rom and it works great apart from the ghost touch issues which is still a problem as on the stock Rom. I'm typing a text and after what could be 2, 5 or 8 characters (it changes everytime), it send the text automatically as it thinks I pressed on the Send button.

Right after installing the Spanish Rom and discovering that the ghost touch issue was still present on my phone, I installed the "Quick TuneUp" app to do a screen calibration (wasn't sure which other app to use). It calibrated in less than a second without me having to touch different part of the screen so not sure what it really does but afterwards, I didn't have any ghost touch issues. Then today, less than 24hrs and a few reboots, the issue reappeared.

I'm starting to think that the problem is with my phone and I'd be ready to send it back (if it wasn't for the fact that I probably can't, having bought it new on Ebay UK, not from China, but without warranty though I'm guessing that the UK consumer law must apply even without the manufacturer warranty?).

I'm guessing that a few of us have the ghost touch issue whilst others are immune?

http community.umidigi.com/forum.php?mod=viewthread&tid=116

Being on Linux so not being able to use RootJoy to install new Roms, installing the Spanish Rom was still a breeze thanks to the google translated Spanish instructions so can recommend this method as well.
[Device Reviews and Information] steve0b1:
Well i have tried 3x ROMS now and although my ghost touch issues are rare i have experienced them on all of these ROM's, it's not really bothered me enough to course an issue so fingers crossed that's how it remains...... Hopefully with the lollipop upgrade it can be sorted and it's not a hardware issue? Strange how some people have it worse then others and it comes and go's??

Be interested in hearing from everyone else with this phone? for me so far anyway the issue has only occurred on rare occasions and has been quite minor (ie keyboard close's when typing or the odd miss-spelt word!!!)

As for the phone overall so far so good generally happy ........
[Device Reviews and Information] Chickens83:
I haven't encountered the ghost touch issue yet after 1 week of usage. My only encounter with a bug is I can't render lens flare using Google Camera, it crashes. Open Signal also crashed, but only once or twice. Also too bad I can't save settings for the stock camera, I like it better compared to the A Better Camera app.

UMi says they're releasing a new firmware tomorrow, but they did not state the changes. What do you think are the changes?
[Device Reviews and Information] tracktriathlon:
Yes, I've seen the release on their website an FaceBook page but can't access the ROM on the UMI forum because you now have to log in (I'm sure a few days ago, I could at least read the forums without having to log in):

"The v05 revision of eMAX's rom is available for flashtools! Change log:

1. Fixed issue with some languages having problem with accessing the screen settings

2. Camera has been improved."

Lte Band 20

Does anyone know if it is possible to unlock Band 20. In theory the hardware should be able to support it, but for some reason it's not been implemented. Anyone know why?

[Device Reviews and Information] mauley:
Just recieved my Emax in the post this afternoon. Had a little mess around with it for a bit. One thing that I find to be unacceptabble is when trying to go to Settings -> Display I get a FC. For a stock ROM that is really bad. Everything else seems okay at the moment. I am going to do an upgrade to the latest build and see if that fixes that particular issue.
[Device Reviews and Information] tracktriathlon:
Yes that's frustrating for a stock Rom.

Are you installing UMI's v05 ROM? I might do that this evening to improve the camera and the ghost touches issue though, as UMI didn't mention anything about it, it doesn't look like it's something they've worked on.
[Device Reviews and Information] toxycbob:
Early on in this thread a fix was mentioned. Download AnyScreen timeout from playstore open it once and the system display settings FC is resolved.
[Device Reviews and Information] mauley:
Yeah I am going to install the v05 ROM in a couple of hours and see if the issues are fixed.

I read the entire thread but must have missed that so thank you. I will first try the lastest ROM from UMI then if it doesnt work I will try this method.
[Device Reviews and Information] tracktriathlon:
Any joy with the new UMI rom?

One negative feedback on the UMI forum:

http ://community.umidigi.com/forum.php?mod=viewthread&tid=169&page=2
[Device Reviews and Information] mauley:
Personally i have not had the touch frezzing issue and my ghost touch issues I had before have now gone away. I am not actually sure if it was the update that fixed it or the fact that I took the screen protector off.

There is also a Spanish custom ROM that is floating about which apprently trumps all fo the ROMs that UMI have on offer. I am going to give that a whirl as it has Xposed installed by default.
[Device Reviews and Information] Tashiqi:
Hello,

Am I the only one who gets a "Network connection failed" when checking for OTA updates ?

Also, what is wiped when using RootJoy to update the system ?
[Device Reviews and Information] coolman7:
I want to change IMEI of UMI eMax. I asked it at umi forum and I was told dial *#4634#. But it gave me "Mobile network not available" error message. What is missing on my side?
[Device Reviews and Information] Tautologica:
Afaik there shouldn't be OTA updates so i suppose that message u get is normal.

Updating with rootjoy u most likely lose application data albeit the apps will be restored so use titanium backup to backup app-data.
[Device Reviews and Information] mauley:
I think I am going to send my device back. It gets really hot near the camera lens after playing games for 10mins or when watching a Youtube video. Not sure if this is normal or there is some kind of defect with the hardware. The UMI forums are terrible at the moment so it is hard to get support, something which I did kind of expect would happen actually.
[Device Reviews and Information] tracktriathlon:
I watched 2hrs of video on a flight early July so had the phone in front of me but didn't notice it getting hot. I was on the stock ROM at the time. Haven't watched videos since. Out of curiosity, where would you return your phone to? I bought mine brand new from a chinese but UK based ebay seller so got it quickly but don't know if I could return it.

The phone's been good on the Spanish ROM though I've noticed that my ghost touch issue seem to be that the phone believes that I touched the screen a few milimetres below where I actually touched. Anyone noticed this? It doesn't affect using the phone as most operations don't require to be as accurate as choosing a letter when typing a text.

Can anyone recommend a trusted app for me to check where I touch the screen and where it believes I touched it?
[Device Reviews and Information] mauley:
I ended up sending mine back for a refund. It was bought on Amazon and fulfilled by Amazon so the return process was very simple and I will have my money back within a week. All in all it was just too much hassle for me in the end, even after I though I had solved the ghost touch issue it was still present no matter which ROM was used. The Phone almost burnt me it was that hot, probably I had a defective unit. Anyway the new Moto G will be announced soon so that will be my next device I think.
[Device Reviews and Information] Tautologica:
https://play.google.com/store/apps/details?id=com.cp.stest

I just tried that and it feels like in the lower part of the screen (portrait) touches register few millimeters down than what I thought it should. Also at the sides there is a few millimeters wide frame that does not register touches at all.
