My observations to UMI Zero

Welcome

Since recently I am the owner of Umi zero, and so far I have no major problems with it, but there are a few things to improve:

1 important - fast battery drain !

2 important - the poor quality of photos from the back of the camera - the dark, out of focus !

3 rom should be more customizable.

4 to determine the MAC address

Other problems are not with me. When a umi improve these things, it will be a very good phone
[UMi ZERO Guides, News, & Discussion] rvdplas:
Running the 10/1/2015 release (it says 8/1/2015 though), three issues:

- Email app won't load remaining data, only headers. Clicking the Download Remaining button shows an loading rotating image, but nothing happens. Can't change a setting to "download all instead of headers only" anywhere.

- Bluetooth audio stutters badly (using Jabra Move bluetooth headphones), my HTC One m7 doesn't have this problem at all.

- Dutch dictionary would really be appreciated!

:highfive:
[UMi ZERO Guides, News, & Discussion] littleclown:
More info about the GPS issue: the bad signal is only in car :). I was using 3 different phones as GPS in the same car without issues, so the problem is not in the car :). If I am out - everything is fine, the accuracy is about 3-4 meters.

The compass is not reliable too, no mater how much you calibrate it. If you have any idea can GPS signal can be fixed in the next ROM will be great - if is matter of voltage, tunning or something else like that.

For the reboot problem:

Guys! Check your SuperSU Log.

14.45 and 13.47 were the exactly my reboot times for today. Maybe it's a problem with the root access on our umis?! I'll try to deactive SU and to uninstall apks that ask for root. :rolleyes:
[UMi ZERO Guides, News, & Discussion] politby:
Odd about the GPS. Mine usually only takes a couple of seconds to get a fix, even inside my house.
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
Hey, do you think it's better to use a weaker charger to charge the battery? I read on many places that fast charging is what destroys battery life, and the slower it charges the better results the battery will have...
[UMi ZERO Guides, News, & Discussion] politby:
I have not been using the included charger at all. I am using my old Sony and HTC chargers. I have no issues at all with the battery life, e.g. if I leave it overnight in sleep mode it will lose virtually no charge at all until morning.

Could very well be that the quick charge feature is causing the battery problems for those of you who have them.
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
Yeah I thought so, I think I will use my old charger from a ThL W200... Because it's already proved that fast charging kills battery life
[UMi ZERO Guides, News, & Discussion] littleclown:
Correct me if I am wrong, but how fast battery is fulled depends on the battery and/or phone, if the charger is enough A.

And one another thing - this is not exactly ultra-mega fast charger. If you charge it from 50% looks like really fast, but if you charge it from 0% is pretty normal. This is mainly because the battery don't report correct %.

You can always use another charger with less A, but don't use a no-name china charger, because sometimes they do a lot of damage.
[UMi ZERO Guides, News, & Discussion] spinecki:
Every charger comes from China ;) ... but that's true. I once damaged a sideboard in my Jiayu, because of some ****ty noname charger (what a smell!).

Anyway - i bumbed into http://umifans.com discussion board - looks nice, but still in like early progress or like beta version. Cool though someone thought about it.

Just updated to 3.03 (never done such thing, so it was kinda scary haha). I can finally download and use the apps i wasn't able to use before!:D

Very happy with it, now hopefully the last 11% and first 10% won't drain in like a few minutes like it did in 3.01
[UMi ZERO Guides, News, & Discussion] Olostan:
I have also updated to 3.03, but still have Google+ unavailable. Can anyone confirms that this app could be installed from Play market? Attached screenshot that says that Umi Zero is not compatable device.
[UMi ZERO Guides, News, & Discussion] sipart:
I tested GPS against my Moto g (2014 model) - testing at a window with clear view of the sky - wintery UK.

Fix time MG 6 secs | UMI0 17 secs

Sats in view MG 19 | UMI0 10

Sats in use MG 8 | UMI0 4

So UMI Zero GPS performance seems to be around half as good as the Moto g.

Not checked how it performs in the car using google maps - but obvious conclusion is that it's going to struggle.

Cheers

I try old Samsung battery charger - full charge was about 3h 55min, whit UMI charger is it about 2h ....
[UMi ZERO Guides, News, & Discussion] littleclown:
First 20% goes for 20 minutes for me. The last 30-40% looks fine.

[MENTION=515917]sipart[/MENTION], thank you for the info. Is good to know that you are not alone in GPS problems :).
[UMi ZERO Guides, News, & Discussion] MiguelferraZ:
Well, now I don't know if I should use the original charger or not :/
[UMi ZERO Guides, News, & Discussion] politby:
Well, I would assume the USB port is not directly connected to the battery, rather there is a charging regulator in between. I doubt there is any intelligence built into the wall wart.

So if there is a problem relating to charging and battery life, it would have to do with the charging regulator. Maybe it allows the battery to draw more amps than it is designed for. Which will not be a problem if you are using a low current charger.

You might want to do the factory data reset, it will wipe out all the data so you will want to do a backup.

Than try install to 3.03 again.

Since the previous app or setting could be conflict with the new firmware.

If it can not help you, please contact me again.

Hi Thanks for the report.

I assume that your Umi zero still in 3.01 firmware, correct?

We have released 3.03 firmware which solve most of the problem.

Continued observation

Hi UMI ZERO

My observations apply rom 3.03 - I'm sorry I have not clarified this.

There is one more strange case of - recharge the battery itself (from 48% to 90%) with no connection to the power supply!
[UMi ZERO Guides, News, & Discussion] Robster666:
Hello guys! I'm new here and I am from the Netherlands. Since 3 weeks I use the Umi Zero and I want to share my experiences and concernes due to this advice with you. The phone came with version 3.01. I used it for about half an hour without installing apps. Then I upgraded from Needrom.com to version 3.02 without any problems. That day the phone rebooted 3 á 4 times. The next day I saw that version 3.03 was available so I did this upgrade too. Then the phone rebooted 1 á 2 times a day. I think that it has to do with KitKat cause for the Umi Zero I used a Doogee DG550 and my wife also did. Both phones were instantly on 4.2.2 and they worked flawless. But I decided to upgrade to 4.4.2 KitKat and from that on my Doogee did also reboot 3 á 4 times a day! I tried yesterday with WiFi on but not connected to any Wifi point and I did get one reboot yesterday at about 17:00H. Today I will try with WiFi shut off. There was some guy that suggested that the reboots had to do with rootacces but my logfiles in SU were not related to the reboot times. Well I saw that (and that is mentioned here before) my MAC-adress changed after reboot but I realy don't know if that is always after reboot or this is a failure in phone or KitKat (and I'm inclined to say it has to do with KK).

For the rest the phone works pretty good, fast, stylish, no lags and I charge it with an 2A charger. Battery lifetime is very good. I've disconnected it from charger this morning at 6:15AM, send some Whatsapps, looked some email and photo's and at 11:00AM my battery is 93% full...

Any kind of reaction is welcome and especially the reaction where the solution is mentioned for solving the reboot problem(s)... :D
[UMi ZERO Guides, News, & Discussion] littleclown:
I have a question for guys who have reboots errors:

Are there anyone who still have reboot issues after these steps:

Factory reset.

Immediately after that install 3.0.3

?

If yes - there are still issues in the rom, but the good thing is that reboots looks like rom issue, but not HW issue. (not loke my GPS problem...)

And another question - are there any guys who calibrate the battery and still have battery issues (like very fast drop do 80% for example)? I will test tonight with battery calibrator - this app removes some file that keeps the information about mV and battery level.

64 GB SDXC card not recognized

Hi Everyone:

I put a 64 GB SDXC micro card into the outer sim socket on my Umi Zero but the device wouldn't recognize it. It came formatted with exfat so after trying it, I changed the format to NFTS and it still wouldn't recognize the card.

I then used a 32 GB SDHC micro card formatted with fat32 and it worked fine, although I needed to reformat it again with fat32 based on another users experience.

You can't format a 64 GB card with fat32 as there is a limit of 32 GB.

Anyone else have this problem?

This problem this is easy to solve. Just nail lush on the place where you input SIM-card. Your SIM-card is too think, UMI ZERO accept thickness less than 0.075mm.

If this is still not helping, contact reseller where you purchased the device for a replacement.

Yes, reboots are happening always.

1. Tried with the original ROM

2. Tried with the new 3.03 ROM

3. Factory reset and immediately install 3.03 again.

I was toggling lots of settings but the reboots are still happening. Mostly the reboots happen when the device is idle but one time it happened in the middle of a call which is worrying.

The best work-around is to disable Wi-Fi while the device is sleeping in order to minimize the reboots.

Hi UMI ZERO

music playback issue (streaming)

Hello all!

first of all i'd like to thank you for this device! I really like it.

I purchased it at geekbuying and it's in my hands since 1 week. Still running 3.01 and i can deal with some little bugs. I'm thinking about updating it but i'd like to wait and see other people's reactions, 'cause i'm quite a noob in loading roms (don't wanna burn it the first week hehe).

I use to listen to straming music and the only thing i noticed is that if i play something from soundcloud or google music, every 15-20 seconds the music lags for about 0.5 seconds (very annoying). This happens in wifi and 3g.

Strange is, youtube's sound works perfectly even with 720p videos.

I don't know if this issue comes from the app (soundcloud, google music) or from the device. I will write also to the apps developers. Maybe it's a hardware compatibility issue.

It's like the phone is busy to do something in background, runs out of "buffer" and at the last second starts loading the stream in memory....... maybe i'm wrong :confused:

Otherwise wifi and 3g are working good. Compared to my old xperia T, i get almost double wifi signal and 3g i can't see a difference..

I had a small problem with the rear-glas protection film (the original one i got with the phone): there is a tiny hole next to the rear camera and i suppose it's a microphone. The protective film is not sitting on that hole even if it sits perfectly around the camera. Could that limit the call-noise-reduction function? Anyway that hole is covered up by the "Z" plastic protector, so.....

Last question: is it possible that the SIM extractor tool is made to fit into the earphones plug? I was wondering if i'm somewhere outside and want to change SIM or insert a SD card, i can't carry that tool the whole time with me. I would lose it after 1 day. I tried and it fits perfectly, just want to know if it was supposed to do that :)

IMO, other things to improve:

- Phone call ended by power button (sony did that --> very nice feature) ---> SOLVED! Thanks MiguelferraZ

- Phone app should start with phone keyboard shown

- Frequent calls could be removed because you already have the chronology (on the bottom - left)

- maybe touchscreen with more tolerance (sometimes i really must tap more times on a button to make it switch/move... and i don't have carpenter hands ;))

Anyone agrees?

Thank you! Anyway big up guys!! UMI rocks! :good:
