Hello. Is this phone good for Pokemon GO? Thanks!
[Device Reviews and Information] euroclie:
If you're looking for a phone that can play Pokemon Go in augmented reality mode, then you're out of luck, as the Ulefone Power doesn't feature a gyroscope (Pokemon Go warns you about this and suggest you to turn off AR mode).

But if you're looking for a phone with a beefy battery to play the game without AR mode, then I find it perfect for the task! I'd estimate I can get approximately 5 hours continuous play with brightness at mid setting for outdoor screen readability, without using the "battery saver" built-in dim screen mode.

[Device Reviews and Information] Kathycakes:
Thank you for your reply. I am not really interested into AR so I guess I'll opt for this phone. How is it's GPS? At first I was torn between this one and the Future, but I read that the Future has very poor GPS!
[Device Reviews and Information] cyberdimitri:
Thx for the answer, now i get an error message 'PMT changed for the ROM it must be downloaded', any ideas?
[Device Reviews and Information] euroclie:
There's been some mixed reports about GPS.

I've had no particular with it so far, but some others complain about being unable to use it (the GPS fix is unreliable and skips position all the time) while using mobile data.

It seems that there's some sort of conflict between the GPS and 3G/4G radio modules on some bands, but so far nobody can tell if this is a software bug that could be fixed by another OTA update, or if this is a hardware design flaw that can't be cured.

All I know is that in France with the Orange network I have no issue with either apps like Waze for in-car navigation, nor apps like Ingress/Pokemon Go wich obviously need Both GPS and data at the same time.

You'll definitely want to check with other users here to see if those affected by the issue are in a similar or different setting as yours (country/carrier).

I'll check when I get back home, maybe we can make a list of the bands that are suspected to be affected by the GPS problem, and find out if it's a per-device issue or a global problem...

For me gps works really well, it locks faster than my iphone 6 and my tab s2 and here maps and sygic work like a charm, never played pokemon tho :/
[Device Reviews and Information] IscreaMan:
After research i can confirm, that GPS doesn't work (no FIX) only while on 4G (LTE). WCDMA (3G) or GSM (2G) doesn't affect GPS. This issue exists in every Android 6.0 rom - since first MM release up to 20160718.
[Device Reviews and Information] lenkosmrk:
On which band you are on with LTE? Can you test or anyone else on difrent band? Just to confirm is not band (frequency ) related. On Lollipop GPS+LTE comination was working OK?

So I recently brought a 64gb Samsung Evo micro SD. Phone says it's "corrupt" just got a new sandisk 64gb and it's saying the same thing. What the hell is wrong with this phone...
[Device Reviews and Information] AngelOfBlood:
Try instead "download" button change to "Upgrade firmware"...

Tell me later if it worked..
[Device Reviews and Information] Kangburra:
The partitions have changed, if this is expected then change download to upgrade firmware.
[Device Reviews and Information] cyberdimitri:
Thanks guys, it worked, running MM now :D
[MENTION=598986]Kangburra[/MENTION] it wasn't expected, the phone was running on it's stock rom and i didn't do anything to change partitions (adding an sd card doesn't do that, does it?)
[Device Reviews and Information] SharpSA:
As I tried this phone is use only FAT32 and not exFat. So that is the problem.
[Device Reviews and Information] Kangburra:
If you went from Lollipop to Marshmallow they have changed the partitions, so it is expected. If you downloaded the same type of Rom and get this then it is not, suggesting malware or an incorrectly built Rom.
[Device Reviews and Information] bjbirch:
I would speak to Amazon, was the order fulfilled by Amazon?

I am using a 64gb SanDisk SD card without problems. Tried to format it using the phone instead of computer?
[Device Reviews and Information] Hemphiz:
[MENTION=352049]SharpSA[/MENTION] & [MENTION=4464714]dreadkopp[/MENTION] appreciate your replies, been using a 16gb exfat since I got the phone with no problems. The new one I formatted many times. Worked fine in other phones until I used it in the power "corrupt" Thought I'd try and blow some air down the sd/sim port before bouncing it off the wall and that seemed to work. Allgood now :)
[Device Reviews and Information] Kathycakes:
Thank you for your replies, cyberdimitri euroclie. I use a portable wifi device, not 3g/4g so I think I should be fine. I'll let you know when I get mine just to put in my part of information towards the GPS matter.
[Device Reviews and Information] IscreaMan:
I don't remember if 4G + GPS was working properly on Lolipop.

On Marsmallow:

3G-4G and GPS

Hi all, MM 07.18 here, I've made a few tests from my 1st floor balcony, among buildings. Unfortunately I'm too young here, so I am not allowed to post pictures, but with both 3G and 4G on, the GPS works fine: I could get a fix in 6-8 seconds with 7-8 satellites and after some more seconds, a total of 12-14 satellites.
[Device Reviews and Information] lenkosmrk:
Hi thanks for reporting that. Please check yours 4G Band, and report it here.

IscreaMan is having problem on B3 (1800 MHz).

Thanks, Lenny
[Device Reviews and Information] fester40:
[MENTION=358361]lenny[/MENTION]: I've just found out that my home is covered by B3/1800 as well. I've repeated the tests and the results are again very good, as in my previous post, so, no problem at all for me.
[Device Reviews and Information] lenkosmrk:
Thanks for replay. This confirm that posible frequences interference GPS/LTE is not cause. Its something with FW (updating/flashing).

Its only one version of Ulefone Power and is not hardware error. It must be software/firmware.

When did you puchase your Ulefone Power? Did phone came with MM , or with LP?

Have you done any upgrades(OTA/flash)?

Thanks for helping clearing out the cause (source) of gps problem.

Best regards, Lenny
[Device Reviews and Information] fester40:
Hi Lenny, I own the Power since about 45 days, it came with LP and I immediately upgraded it to MM; I never did any OTA upgrade/update, only by SP flashtool or TWRP. I'm no expert, but I would suggest to those having issues to download the OFFICIAL MM 07.18 rom from the Ulefone site, and make a CLEAN installation with SP flashtool set on Firmware Upgrade.
[Device Reviews and Information] u.s:
I ordered my Ulefone Power from Amazon UK.

It arrived with MM already installed.

I have done the all the wireless updates and the phone is now at 07.18 ROM.

The only issue I have noticed is the screen auto brightness doesn't seem to work.
[Device Reviews and Information] lifeshit:
Hi, I've ordered my power on Amazon.it arrived with MM on board it fix GPS every time but when I open maps tomtom or waze in navigation mode it lost GPS signal...
[Device Reviews and Information] 3dd1:
Was the seller hifone? That's who I got mine off through Amazon uk, I hope you don't get problems with it, their customer service is some what lacking shall I say. If you go back a few pages you'll see my problem and their response.
[Device Reviews and Information] u.s:
Yes it was sold by Hifone but delivered using Amazon Prime.

Can you raise your issue with Amazon?

hi,

i just want to know if anybody else is having problems with the earspeaker during phonecalls. for me sometimes the earspeaker doesnt work, but not always. it started a week ago and even with a factory reset it doesnt solved the problem. i restored my apps and personal data, probably that could be the problem. i just want to make sure if its a hard- or software problem. so please report back if u experienced the same. i'm very confident with the phone at all, but thats a no go. thx in advance for replies.

Hi,

Is there a way to came back on lollypop?

Seems that GPS problem is on MM...
[Device Reviews and Information] fester40:
I'm on MM and the GPS works just fine
[Device Reviews and Information] cyberdimitri:
I never had any issues with it mate, using it all the time.

Do you have the same problem with other sources (mp3s, FM radio etc.)?
[Device Reviews and Information] AngelOfBlood:
Hey mate

I had the same problem, I reported to Ulefone Service Center, and they ask me to send to warranty because speaker was broken.

This is not true... The Ear Speaker works well with internet services like "Skipe, viber, etc.." so I test the MTK Engineering Mode Speakers volume, and put it to work.

In this last Ulefone Update the speaker is working without any configuration in MTK, so for me is all ok.

Give it a try, tell me later.

Sorry about the bad english.

Hi, yes it's easy. Download the latest lollipop from needrom and flash it. The instructions are probably provided along with the rom.

Use the option in the flashing software to erase or format the memory first since the partitions size aren't the same.
[Device Reviews and Information] Ziegenjupp:
ok, so i will try to do the upates and report back. i have to flash stock recovery, do updates and after flash twrp and supersu again, right?

---------- Post added at 06:08 AM ---------- Previous post was at 06:02 AM ----------

no, just phonecalls dont work sometimes. . .
[Device Reviews and Information] 3dd1:
I've raised it with Amazon and they're investigating it, looking for a full refund

---------- Post added at 12:41 PM ---------- Previous post was at 12:38 PM ----------

As just posted, they're investigating it, the question is, if I get a full refund and they want the phone back, I guess they will, what do I do if I get it? Buy another Ulefone Power, which would be though the same seller in Amazon, or get something else? I do love the 7-8 hours screen on time, when working it's a great phone really for the money.
[Device Reviews and Information] Zubcho:
Do you guys know how to go back to stock recovery? I can't find it nowhere. I want to do OTA upgrade, but with TWRP you can't do OTA
[Device Reviews and Information] kozelos:
Just flash "system" from the whole rom package accesible thru goole drive at ulefone support site thru flashtool and then boot to recovery and restore root. No need to use ota
[Device Reviews and Information] 3dd1:
If you down load the latest ROM from Ulefone, it's in there, you can flash just the recovery, iirc.
[Device Reviews and Information] dreadkopp:
Keep in mind that it's update will still fail if you did any changes to the system partition (root/xposed/remove/replace system apps/etc) even if you revert recovery to original one since the update checks if system partition is in original state
[Device Reviews and Information] 3dd1:
How do you get past that, do you have to flash everything, set sptool to firmware of the newest complete ROM available, then run OTA?
[Device Reviews and Information] Ziegenjupp:
can i just flash the system from the 0708 rom or do i have to flash rom, make the update and then root again? if so, can i use my backup from apps and personal data!

ok, i will unroot, flash rom from 0708, then make the ota and then reflash twrp and root again. then i report back if speaker problem still exists.

greats
[Device Reviews and Information] dreadkopp:
For updates I just simply flash the system and boot image from the latest Rom provided by Ulefone. The reinstall xposed framework and supersu. Takes about 15 minutes max per update. I use fastboot to flash the images. next time I will consider repartitioning and make the system partition smaller (~3,5gb right now, I'd like to shrink it to 1.5 - 2GB.. Should be more than enough)
[Device Reviews and Information] Gavin01:
Just discovered a wierd bug... If I'm listening to tune in via ear phones and I like something on Facebook it then activates the loud speaker!!??
[Device Reviews and Information] 3dd1:
Lol, that's a good one!
[Device Reviews and Information] dreadkopp:
For reverting to lollipop it's sufficient to download lollipop rim from ulefone and flash boot.img system.img and cache.img
[Device Reviews and Information] kozelos:
Why dont you read? Download latest full rom package from ulefone site and thru flashtool flash just system. Then boot to twrp and flash superuser again. Thats all, much easier than trying unroot, flashing stock recovery etc for ota which may still fail
[Device Reviews and Information] lenkosmrk:
hi. Proud new owner UP here.

Question for all, anybody use IR , and if whitch app works best.

[Device Reviews and Information] bjbirch:
If You buy another ulephone power from Amazon,make sure it is a fulfilled by Amazon listing,then you won't get fobbed off by the seller and can return the phone to Amazon if there are any problems
[Device Reviews and Information] Ziegenjupp:
ok,

i flashed newest rom from ulefone site, no ota found (guess its in the rom) and earspeaker is working during phonecalls so far. i restored thru ulefone app my apps and personal data.

[MENTION=448231]AngelOfBlood[/MENTION]:

thx for advice, now its working
[Device Reviews and Information] Kangburra:
I use this and it works perfectly
[Device Reviews and Information] AngelOfBlood:
;)

Mine to and the problem was the same... Only in phone calls the earspeaker don't worked, but in calls over wifi works great.

I deduce it's apk rom problem, codecs, internal codes, don't know but hardware isn't !

It's great now.
[Device Reviews and Information] fedenl:
Hi,

I did the installation of the latest update with flash. Then I used twrp to install superuser again, remove the nice present left by the Ulefone developers located in system/app/CallerIDSearch/, installed again Xposed and SELinuxModeChanger and everything seems to be OK.

I only have one issue, probably something i forgot. When I start SELinux I get a popup saying "App was unable to gain root access" but I can see in SuperSU that it has root access.

Any suggestions to fix this?
[Device Reviews and Information] euroclie:
I just had a look on the SELinux thread, and on the last page there's this post:

http://xdaforums.com/showpost.php?p=67942598&postcount=417

It says:

and there's a second message stating the same result. If you download SELinuxModeChanger via F-Droid, it seems to work, otherwise it isn't too friendly with SuperSU, it seems.

Note that I didn't try myself (never has reason to use SELinuxModeChanger in the first place, and I'm happy with SuperSU for now)...

Hope this helps!
[Device Reviews and Information] fedenl:
For me the F-Droid installation fails with SELinuxModeChanger
[Device Reviews and Information] IscreaMan:
I've downgraded to Lollipop initial release (with SpFlashTool - firmware upgrade). No problems with GPS + 4G. I will do incremental updates and see when it becomes broken again.

No modification or root for now.

Working superb.

I'm leaving like that and only if i'll miss something, than i'll update-it. OTA update was checkd, and no update for this version.

Just for report.

BR.Lenny
[Device Reviews and Information] euroclie:
Hello,

I'm not sure what you're trying (and failing) to do: you write "I can't open a wlan hotspot while using my handy wlan", does this mean that you're trying to create a wifi hotspot using your phone while it is connected to internet through a wifi network?

If so, that's going to fail because as far as I know there's only one wifi radio module in the phone, so it can't be connected to two networks (your hotspot network and the wifi network that connects you to internet).

The normal use of the hotspot feature is to share via a wifi network the 3G/4G data connection of your mobile phone, although I suppose you could also share a USB ou bluetooth connection if you're lucky, as they let your wifi radio available for the hotspot.

If I got it all wrong and you're trying something else, please can you give more details so that I may try a similar setup on my phone to see if it works or not?
[Device Reviews and Information] Kathycakes:
Hello. I bought the ulefone Power and I'm very satisfied with it. But what worries me a little bit is how much it heats up near the camera/fingerprint area. Is this normal? Also can someone suggest a good brand for a memory card? I want to increase the storage capacity. Thanks!
[Device Reviews and Information] euroclie:
Hello, welcome to this thread and thanks for the report!

I'm glad you like your Ulefone Power.

One little thing, though, to make sure there's no misunderstanding: if you're running Lollipop (March 22nd ROM was before the Marshmallow ROM release), then at the moment you'll never get any OTA.

The reason is that the partition table is different between Lollipop and Marsmallow on the Power, and Ulefone hasn't yet found a simple way to perform the OS change via OTA, only via a full ROM reflash using a PC. So the OTA you'll read about here are only available for those who have a Marshmallow ROM already (and no the first official release which was a bit buggy).

Hope this helps, enjoy your new phone's incredible battery life!

[Device Reviews and Information] rl4engx:
Hi All,

Lurker here, but I've had my Power for about 6+ Months now and am generally very happy, the only faults so far (fairly major tbf!) are the microSD card slot now longer works, and the touchscreen is inacurate from about 20-40% down the screen.

Anyhow yesterday the phone died, it was at 15% battery and I put it on charge (using the pump express charger) and I got a strange warning saying "Battery temperature too low! Please remove charger" then the phone went off and wouldn't come on again. I kept trying and eventually I managed to get it to charge (before this I'd plug any charger in an no red LED) A couple of times it would power up to the "uleFone" screen then die again. However just now I managed to get it to boot up and ran a battery monitor app. It reported a battery temp of 49deg, ramping up 50.0, 51.0, 52.0 [..] 56.0 Then I got a high temperature "Remove Battery" warning then it went off again.

At this point I'd taken the back off the phone to check the power switch and anything obvious, nothing was hot, board was getting 4V so am I right in thinking it's just a duff battery (or more accurately the daughterboard containing the thermister etc.) and swapping it out should fix the issue?

Many thanks,

[Device Reviews and Information] euroclie:
Hello,

I've been using a Sandisk Ultra 128 Gb SDHC card for a while, it works fine (no noticeable slowdown/freeze, and the card is perfectly recognized in my phone, I'm using it as an external/removable memory, not as internal memory).

https://www.sandisk.com/home/memory-cards/microsd-cards/ultra-microsd-for-cameras

The trick is that with MM (at least the Ulefone Power implementation) you have to chose either removable storage (you can still umount the card and read/write it on another device, but you can't move applications from the internal memory to the card) or internal memory (may cause phone to slow down/freeze during memory access, card not unmountable, not readable on other devices, but gives you plenty of "almost internal" memory to install apps).

If you need room for photos/videos/music, external mode is probably better, but if you install dozens of applications you'll most certainly need internal mode. For internal mode, go for the fastest possible card you can afford, speed might be more important than capacity... Something like this, for instance :

https://www.sandisk.com/home/memory-cards/microsd-cards/extremepro-microsd-uhs-ii

(Disclaimer: there are other brands, and also I didn't perform any benchmark to see if there's an actual advantage to using a super-fast card... Feedback are welcome!)

Hi i just received the phone but i put a sd card in it and is not working.

The slot is naturally temperamental, well at least mine and a few others are, I often have to reinsert it (slowly) once it's in place - no problems. (it goes in horizontal, not vertically like the sim card) Also try blowing the slot. Dust caused mine to read SD cards as corrupt
