Why does your Play Service take up 1 day and 2.5 hours of running time with 10% battery usage?

I hate to burst your bubble, but the battery life, according to your screenshot does not look much better than on Stock ROM.

Here's mine:

View attachment 4839233

You see, with almost 7 hours of SOT you can squeeze three days out of one charge.

Google Play Service doesn't show up in my list of apps and services using the battery. So the Stock ROM ain't that bad either. :)
[Miscellaneous Android Development] Cristallx:
Hello,

Thank you for pointing out that play services consumed a lot of battery. That had escaped me. I restarted the phone and Play Services now seems to use less battery. I don't know what the cause was. I am now charging the phone and will later share my battery consumption again. :fingers-crossed:
[Miscellaneous Android Development] Cristallx:
Unfortunately the problem with google play services is back, it's always running in the background. This indeed ensures battery drain. I don't know if it is due to the rom, but maybe other ERAGON rom users can check if this is also the case with them. It is very possible that this is not rom related.

Sorry for my bad english :(
[Miscellaneous Android Development] skeleton1911:
Checked It and don't have that play service in my background.. .look yourself .

Maybe it's something you use. But it's not rom related.

Thats what i thought , but it is not easy to find out which app is causing this.

The rom is still great , thanks for that :good:
[Miscellaneous Android Development] BZ0RG:
Looks very good, especially with the incoming sale!

If you ever buy it, do you plan to build your Eragon rom for it? I am so sad for not having tried it since I do not have my F1 play anymore ?

Yes

[Miscellaneous Android Development] InTheY2K:
Which version of Google Play Services do you have installed? There was an issue in August with an older version 18.something draining the battery (see https://xdaforums.com/showpost.php?p=80065031&postcount=277).

To find out which one you have, go to Settings --> Apps & Notifications --> "> Show all apps" --> "3-dot menu top right" --> Show system processes --> scroll down to "Google Play Services" --> tap --> Advanced --> scroll down to bottom.

I have 19.4.20 (100408-271418971).

In the other thread I quoted above there is a link to apkmirror where you can get the latest apk for the Play Services. But watch out that you don't install the wrong version, like I did! ;)

[Miscellaneous Android Development] Cristallx:
Thanks for the tip, have now installed the same play services as you. I'm curious, I had the latest version of play services.

"Rule #1 on XDA: Never, EVER, ask for an ETA!! ;)" :o:o:o:o:o
[Miscellaneous Android Development] Cristallx:
Also with this version of play services 19.4.20 the same problem. Does anyone know how I can find out which app is causing this problem ?

Thanks,
[Miscellaneous Android Development] skeleton1911:
I would install each app, and see what happens after some time. Step by step , one by one..

[Miscellaneous Android Development] Cristallx:
I think I finally found the cause. After uninstalling the app "Google Find My Device" it seems that the play service is using less battery now. I'm going to keep an eye on it for a while.

Thanks ,

Question

Hey, Does your rom make better photos than normal rom? is there any improve?, do you have a video of the rom?, finally, does this rom work on the global version of the phone?
[Miscellaneous Android Development] skeleton1911:
Same photo quality as stock at the moment.

No video . Just give it a try and you will See. :D

Its improved in performance and battery life.

Also it works with global and EU Version..
[Miscellaneous Android Development] BZ0RG:
Use v20 beta or revert to previous version
[Miscellaneous Android Development] stw500:

Hello there! I'd like to start building something for the regular F1. Could you give me any tip?
[Miscellaneous Android Development] skeleton1911:
What a question?!

What do you want to build? What tip you need?

You can build apps or do some system related stuff. For all things you need knowledge. Sorry to say that. But if you want to build things, then do it.

Tips are not necessary .

[Miscellaneous Android Development] SnapTheRipper:
Well probably it's kind of a dumb or incomplete question, but I actually asked this bcuz well, F1 Play it's almost the same as F1. Would it be hard to make some adjustements to this ROM to fit the standard F1? Like camera related stuff?
[Miscellaneous Android Development] skeleton1911:
I am not 100% sure.

Maybe it's enough to change the camera files/drivers , and boot.img . Maybe also some system Framework files..

But I can't test and help. I don't own the normal F1 .

Gesendet von meinem F1 mit Tapatalk
[Miscellaneous Android Development] SnapTheRipper:
Well I'll try to boot this into my F1, only ditching some stuff. And see how it goes. It's the same device pretty much, so I wouldn't be surprised if it only crashed on camera :/
[Miscellaneous Android Development] skeleton1911:
Boot.img is important too. Just if it don't boot.

And Thing about magisk. A Patches boot.img of the normal F1 is necessary.. . (Same magisk version as in rom, not the updated magisk)

Flashed with "firmware upgrade" and it did it but couldn't boot. Got something like : "red state your device has failed verification and may not work properly download proper image or disable verified boot" ..

any ideas...???
[Miscellaneous Android Development] skeleton1911:
Yes. In firmware update the bootloader get close again. You have to reopen the bootloader with adb fastboot

HELP

Hi everyone,

I want to install this ROM on my Umidigi F1 Play, but I can't :(

I've tried by many different way.

But every time I have the same result : Red State on screen with message Your device failed verification and may not work properly. Please download boot image with correct signature or disable secure boot. Your device will reboot in 5 seconds

It's seem the bootloader is lock after Firware Upgrade, and I can't unlock it because can't boot to choose OEM unlock on Devolopper Options.

I've tried every advice I found on this forum but it;s not working :(

For now I can just back to stock recovery for using my phone.

Please help !

Sorry for my bad english :P
[Miscellaneous Android Development] InTheY2K:

[Miscellaneous Android Development] Nobaddy:
I would love to try this but the fact is I can't go into Developer options and OEM unlock because my phone can't boot, I tried fastboot flashing unlock but it's failed after the Red State at boot it's just reboot again and again.

What I tried :

I have stock ROM with bootloader lock.

I unlock the bootloader, and then flash Eragon ROM with Firware Upgrade option in SP flash tool.

Then, can't boot, can't unlock the bootloader again.

I've tried download Only options but the same result.

Maybe I missed something ??
[Miscellaneous Android Development] skeleton1911:
Well you have to flash the latest Stock Rom again. Then enable OEM etc.. in Developer settings. And flash my Rom. With normal Download Mode...

The reason why you have to use firmware upgrade is only if you are not on latest stock rom.

[Miscellaneous Android Development] KevlarAndChrome:
Thank you so much Skeleton1911, your ROM is excellent. Everything that I need to work, works. It plays nice with Substratum and EdXposed, the battery life is unbelievable (4 days to go from 100% down to 18% with 6+ hours of screen on time), and the Goolag apps stay disabled unless I plug into a USB on a computer. :D I'm used to using the pico version of GApps with my previous phones, so the less Goolag the better. :good:

Now to my question; if I install TWRP and make a backup, will I be able to use that backup, even though the main storage is encrypted, if something happens? Or will I have to flash your ROM again from scratch and set everything back up again?

Thanks for all the hard work, the ROM is awesome.
[Miscellaneous Android Development] skeleton1911:
Thank you very much for your kind words.

Well a twrp ist useless because of the encryption.

I would flash the Rom again with flashtools when something goes wrong. Without userdata first. Then all your apps etc stays..

[Miscellaneous Android Development] KevlarAndChrome:
Thanks, I'll skip the TWRP then.

[Miscellaneous Android Development] Shadow Of Leaf:
hello

i have a umidigi f1 play for more than 3 months and

i read that some need to decrypt data on that firmware

to be able to use decrypted firmware you need to format data and flash Disable_Dm-Verity_ForceEncrypt to use a decrypted data on twrp

i think that the official firmware can be flashed on twrp i tried a lot of times and it works so this will work too

for suggestions can you deodex the rom to be easier to modify ?

and we need a support to treble project on that phone

thanks for the rom

[Miscellaneous Android Development] Dontwait:
hi, sorry to bother you, but im having problems with booting (red state; before flashing the ROM, i had bootlader unlocked; i flashed with "firmware upgrade" because had problems with flashing, and i saw you saying not to used "format+download")

i tryied to re-flash the ROM with "firmware upgrade" and "download only" but still red state. Looked on fastboot and seems like that now i have the bootloader locked, and i cant force it to unlock it; i tryied even with "fastboot oem unlock" but terminal says "command unknown" and im using the latest ADB and fastboot.

Plus, seems like i need to "format+download" but you disagree with it, but with other devices i did that without problems. Please i need this device for work as soon as possible.

EDIT: I have flashed the "original" boot.img, and now it works, kinda. Bluetooth and WiFi doesnt work. MAC addr and bt not showing up) there is something inside boot.img which you modded and doesn't work. Or meaby im stupid and i dont know what was cousing the issue with bootloops. -_-

How did you get around the boot loop error "red state Your device failed verification and may not work properly. Please download boot image with correct signature or disable secure boot"

I am having the same issue. I unlocked bootloader and flashed using SP flash tool version 5.1924.

Once I flash factory ROM it works. Then I repeated the process of unlocking bootloader and flashing Eragon in SP flash tool and I get the same error.
[Miscellaneous Android Development] skeleton1911:

That worked thanks.

Great ROM so far. Only thing that I will change (this is more of a personal preference than a problem) is Nova launcher.

The camera is really bad in terms of picture quality. If someone or Umidigi doesn't come up with a better camera software, I think I will be returning the phone.

Pictures are completely useless by today's standard. I have a Xiaomi Redmi 7A that costs less than half the price of the F1 play and takes better pictures.
[Miscellaneous Android Development] InTheY2K:
You may want to give Lawnchair launcher a try. It's really great to customise.

Yeah, the camera is a shame. And it used to be really good in the beginning. But it got worse and worse with every update. [emoji17]

When you flash firmware the OEM unlock gets overwritten.

1. Flash latest stock firmware with firmware upgrade. And reboot

2. Enable developer settings OEM unlock

3. In adb and Fastboot mode. Unlock the phone.

[Miscellaneous Android Development] jugarh:
Thank you, the ROM works well! :D:D I am going to use it for a few days and report back here. Hopefully, Eragon V 2.0 has android 10 and UMIDIGI comes out with a camera update.

First impressions have been mostly positive: love the removal of bloatware and longer battery time. Just a minor negative feedback, so far: the nova launcher has been acting "weird". The wallpapers show up sometimes, sometimes they don't.

Some back story

I wanted to share about my experience with UMIDIGI F1 Play: I was using stock version for about a month and then suddenly the phone crashed while using the camera app and got stuck in bootloop. I was able to "fix" it by flashing latest stock ROM with SP Flash (from UMIDIGI community).

Since I lost most of everything, I wanted to try out Eragon 1.0 so I managed to unlock bootloader by turning on OEM/USB debugging (in stock rom) and using adb. I tried flashing Eragon 1.0 and my phone bricked! No bootloader, nothing! I ended up reflashing the stock rom where I had lost my IMEI. There was permanent red text in chinese:

TEE: 未 激活

Google ： 未 激活

I used SN writer to fix my IMEI. Unlocked bootloader with adb, again as it got locked for some reason. And tried again with latest SP Flash 5.1936 to add Eragon 1.0. And it worked! :)

Let me know if I can buy you a coffee or something.

Great work on this ROM, OP. Thanks for everything you've done. I'll also make a donation if you provide us with a method. This phone needs more love and there should be more people using it. With great ROMs like this one, I hope this phone will get the attention and following it deserves.
[Miscellaneous Android Development] moresat:
Hi Eragon, is this already the new version or still the 1.0? I got your rom on my old Z2 and very satisfatied with it.

Was time to change phone now and I just bought today the F1 Play (the price was right: 149 €) quite only because I know I can play your Eragon rom on it.

Umidigi are good phones and Eragon are good roms. A perfect marriage. Why change?

That's tha why I supported you also if the Z2 rom develop was stopped. It is right to reward a good work even if it is given for nothing.

phone won't boot

Thank you so much for your work on this rom. however, i think i briked my phone.

Just in case it's relevant, I'm using sp flash tool 1.519 from Ubuntu.

i unlocked bootloader and installed Eragon but on reboot it showed red status. I switched off and it wouln't start again. I think it's in continuos boot without displaying anything.

I've probably done something wrong (i cannot recall all steps I took). can anyone please share a way to recover from that?

I'm trying to flash stock now but I can't make it work. The download starts (red bar at the bottom starts and goes to 100%),but then it times out after 2min with error STATUS_EXT_RAM_EXCEPTION.
[Miscellaneous Android Development] johnsecada:
ok, note to those who may make a mess like i did:

I don't know for sure if i did format+download (cause i tried many times and i may have done it without realising), but in the end i managed to recover the phone.

as some people have said, you can recover from almost anything. in my case, the problem was Linux. it may work when the phone is fine, but not when it's in a loop (or i couldn't make it work).

i used virtualbox and windows10 and worked just fine.

i lost imei,etc, but i kept the box, so i copied the numbers with SN Write Tool.

however, my screen shows a TEE/Google validation error in Red (and Chinese). the SN tool didn't fix that and I tried to flash eragon and stock again after running SN tool and it won't go away.

Any ideas how to get that removed?
