Need help with my A520F battery drain! - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

4 months old, upgraded this device to nougat a month and a half ago using odin and russian firmware. Everything went fine. After a few days, I noticed that my battery is getting weaker especially when idle. It is getting drained by 5% per hour and i cannot find any solution for this. Tried running in safe mode, low power mode, clear cache, factory reset but none worked Also tries to flash a different nougat firmware. The indian and cyprus one but it didnt help. So i didnt lose hope and downloaded my original stock firmware. I rollbacked to MM firmware (philippines version) and NOTHING CHANGED. I waited for the OTA nougat update and installed it via ota. Didnt help as well. I downloaded Wakelock Detector Lite for non root users. It seems like my kernel is keeping my phone awake. I think its called "wakelock". These items are keeping my phone awake while idle: "event1" 1232712 times. "KeyEvents" 890231 times and "eventpoll" 1467271 times. I got shocked when i saw it. A million times? Omg. How can i fix it? My battery only survives for 10 hrs with 2hrs sot. I need help xda!! Pls help me!!!

I would advise to flash a stock Nougat (preferably for your country) using Odin and CSC file (not HOME_CSC, in order to start clean) and at first, do not enter your Google account, do not even enter your Wi-Fi networks, use only GSM, and wait 1-2 days to see if the drain is normal. Do not add a fingerprint and to not enable Knox, do not enter your Samsung account. Then at first enter your Google account and disable all synchronization for the account, see how the drain changes. Then enable Wi-Fi, your Samsung account, one at a time and see how it goes.

elephone p8000 can't access network or google play neither via wi-fi nor cellular dat

Hi there,
Excuse the novice. Just got this 2 days ago and I am still trying to figure it out why I can't access the net at all.
I have not got Android experience much and I am digging now how to come out of this situation.
So no option to access Net at all. The Error in response is " Couldn't sign in. There was communicating problem with Google servers . Try again later." So this is like a loop there.
Android Version -5.1
Baseband Varsion - MOLY.LR9.W1444.MD.LWTG.MP.V16.P10
Kernel Version - 3.10.65
Build Number -ALPS.L1.MP3.V2_NB6753.65U.L1_P22
Custom Build Version - Elephone_P8000_20151014
I must admit the Phone came preset and once I have switch it on it picked up GMT time without I have set anything.
I will appreciate any help or pointing to a resources to try to solve as now it is unusable as I can't download anything.
Thanks in advance.
Check:
Settings --> Data Usage --> (cellular provider tab) --> toggle 'enable mobile data'
See if that's the issue. Good luck.
Now Stacked to The Elephone Logo on and unresponsive.

Thanks kevvyboy,
I can't do anything right now. The phone by itself (really) got in a mode I can't read even with letters so small, went to the Android Man with red Mark and now is in front of me unresponsive with the logo of Elephone totaly unresponsive.
Just to underline - I have not touch anything- I have left it on stand by last time I have played with it.
Any clues and help please will be much appreciated.
PS. NOW I have managed to (I guess Switched it off) and again on and there was window with APP UPDATE - came to 116 out of 116 updated and now again can't access the net neither Google Play.
Could this be a OTA Update completed somehow?
Thanks everyone in advance!

Hi again,
I have enabled the cellular data - no luck again.
When I am trying google play again message Google servers can't be reached and the more interesting - using the - preload browser it try to search trough yahoo search. This phone was sold to me as new, but I am starting to wonder what it has been through before it reached me?
Will a flash using PhilZ Recovery will help?
Could someone point me the way out of this please?
Thanks!
New bizarre Message.
Hi again,
Just to make it more interesting out of the blue it Popped up a Message box with following wording.
"In a Previous Android Version You have disabled all Google App services. Do you want to enable them. Yes/NO,
Of course I have chosen Yes and Again Can't reach net neither via Cellular data nor Wi-Fi.
Any useful contribution will be much appreciated.
Thanks!
Stuck on Airplane Mode? Try toggling it on and off. I remember my HTC OneX having an Airplane Mode issue - had to toggle on / off several times and reboot.
ETA - faulty APN settings for your provider? May explain a mobile data issue, but doesn't address the wifi issue.
Dammit.
Got It Work on Cellular

Thanks Kevvyboy for your contribution.
Somehow I have managed to get the Cellular data connected and now have updated the Google Service.
WI-FI still an issue. Is there any sense - updating a driver (if I am not asking stupid question here)?
Thanks!
Glad to hear at least cellular working! The wifi issue is a bit of a mystery to me though - I'm all out of smart ideas, sorry
Hopefully some other bright soul can chip in.

download drivers for SP flash tools and SP flash tools program.
go and download mediatek drivers and sp flash tool.
you can get these from elephones website, google or where ever. i got mind from needarom. i used the latest versions for both.
i downloaded the 5th November 2015 firmware from elephones rom. it came pre 7-zipped. i unzipped it and left it's structure.
installing the drivers part:
you need to disable signature enforcement in your OS to install the drivers.
open SP flash tools.
load the scatter file in the official rom folder you unzipped with 7 zip.
at this point press the download button in SP tools.
switch off your phone. connect the usb cable to the phone and the computer.
you should now have the latest firmware on you phone when complete.
please note it wipes everything, so back up anything important to you.
once done, set up your apn in settings, mobile networks, access points.
wifi should work after a clean factory reset if you don't have a dodgy device.
elephone only supports 2.4ghz for wifi as far as a i know.
also make sure your network bands and are supported by the p8000.

Hi El_Nino9,
Thank you for the reply and sorry I am delaying my response. I have actually done some of the suggested previously once I read more on the site - thanks for the contributors here. I had Eragon 9.5.0 Custom ROM set with Philiz recovery tool after Mediatek driver download but the wi-fi is still an issue.
I will try to perform the the one suggested from you, I just have located the latest Elephone p8000 ROM on the Elephone site and will perform this on a first chance I have. - most probably on Friday.
Thanks once again and I will post an update from the outcome.
OK!
I have done the upgrade to the 05.11.15 Stock ROM.
Have made a Factory Reset and the Wi-Fi is working as before but I can't reach internet basically.
Again after attempts to get to Play Store or to or to perform a simple Google Search it comes again after message "Just a second" and after 20- 30 seconds it end up with the message.
"Google Server can't be reached at the moment please try again later."
Any help on this will be much appreciated!
Thanks a lot in advance!
P.S>
I have just discovered that the icon of the WI - FI showing a processes going on but I can't reach My Router URL for example through the Local network.
Does it mean this is really dodgy unit or I am missing any settings or there is any cure for this?
Thanks again!

so your mobile data still works on the latest firmware? specially after typing the correct apn settings?
regarding your wifi, where is the router in relation to your position? far away? standing right next to it with the phone? whats your encryption for your wifi? tried changing that to a different type and seeing if it connects?
if you have big concrete walls and live in a nice solid building that may too cause signal not to reach. the wifi isn't that great on the device speaking from experiance in comparison to other devices.
if all fails... possibly dodgy device

Hi EL_Nino9,
I guess either the p8000 not like my D-LinkDIR-655 router or I am missing something in general.
I have an extension for the other rooms and the phone connecting to a simple TP-Link with no hassle at all, but D-Link is like a brick wall - you see the wi-fy working but no internet access.
It is still a mystery.
At least is proven the wi-fi module is working.
Believe me - I have tried to alter the setting on the route and still can't get to the net content.
Will keep exploring this and will report if any luck.
Thnaks!
I´m facing the same issue here. Google-Services like Google-Photo, Gdrive, Inbox are not working. Any solutions so far?
Looks Like I have rooter WI-FI issues

Hi kraftmaschine - I have discovered that my aged D-LInk DIR-655 was giving me problems dropping out the signal. I had an access through mobile network and through my other room extension rooter, so I got on mind either compatibility issue or router problem. So I have upgraded the router and voila. Everything got sorted.
Also upgrade to the latest mod - not OWA but using the standard methods described here.
Hope that helps.

Cellular data stopped working, help

Zenfone 2 ZE551ML on straight talk,
stock ROM 5.0.1 latest release(not beta tester).
have tried resetting APN settings
Have set APN settings to straight talk directed settings.
have multiple disabled and enabled data and disabled data caps from phone.
multiple restarts, multiple attempts to manually choose network with error messages saying cant connect at this time try again later.
AT&T should work just fine even t-mobile LTE service. they both worked a couple days ago.
ive contacted straight talk and they've had me reset and update the APN settings. had me restart the phone a few times, no luck
still receive texts and calls just fine.
any advice would be great. (if i can avoid resetting the phone to factory defaults or installing a custom ROM that would be ideal)
thanks,
I have straight talk and while I never had a problem with data I have had some other problems. Any problems I ever had was solved by dirty flashing the same rom I was running. Since you are on stock you should have no issues downloading .184 LP from ASUS and using stock recovery to update with ADB. On a side note I have been running the MM beta since it first found its way on his site and my service has never been better, don't be afraid to try it.

8.0 update made mobile data not work

I have the Honor 7x, and recently update to the 8.0 Oreo android update. Immediately after the installed the update in the morning, I noticed that my mobile data was no longer working correctly.
Wifi can connect, I can make phone calls, send text, literally everything else about the phone works perfectly.
A day later I got another update 8.0.0.332, however I am still unable to access my mobile data.
I use At t for my phone service, and do not have any damage to the phone (havent dropped the phone, water damage, etc).
My friend has the exact same phone, with the exact same phone service, and got his update the same day without having any issues.
Thing I have tried in attempt to fix the problem already based on google searches:
I have tried turning my phone into airplane mode, waiting, turning off airplane mode (also with trying a hard reset on the phone).
I have switched my simcard to slot 2.
I have put my simcard in another phone, and verified that the sim card is still working properly (the other phone was able to access data just perfectly).
I have tried turning off 4G data, and putting it back on.
I have tried resetting the APN back to default.
I have tried manually typing in my APN.
I have also tried network setting reset.
And finally, I have tried a factory data reset.
Running out of ideas of what else to try, hoping you guys have some ideas to help me out with this problem
Much thanks.
Flash a ROM and see if that does anything, if you want. Another thing to do is to do what the post below mind says, thanks.
Or join the Telegram Honor 7x group chat lol

Power saving mode - Can't change this setting in demonstration mode

I have a Samsung Galaxy S20 Ultra (Exynos) and when I try to activate the Power Saving Mode I get this message: "Can't change this setting in demonstration mode". I looked under Developer Options and the Demo Mode is not enabled. Any idea why the option is greyed out (Under battery settings) and giving this message (when clicking it under settings or under the notification shade quick toggle) ?
Thanks
Personally I never use this mode as it goofs up display settings.
Maybe the firmware is corrupted; if so not worth reflashing if this is the only issue.
Try clearing the system cache and a hard reset.
Try turning off Developer options.
If that doesn't get it, boot up in Safe mode to rule out a 3rd party app causing it.
Factory reset but I don't recommend it...
hi there im also having issue on my note 20 ultra and i stick cant get it to worl
hello is anyone here that can help me solve my issue i won a note 20 ultra and i have the same issue i cant seeem to fix it were you able to fix yours and if so please how didi you go about it thanks
I've tried clearing the system cache, hard reset and also flashed the latest android 11 firmware and still I get the same message when trying to enable power saving mode. I did not reset the CSC when flashing however, to not lose all my data. I have a strange WWB active CSC. I gave up for now.
Sir do you personally think its a hardware defect or a software update can fix it, i tried flashing a combination firmware but i was getting a pit file issue
this is very frustrating honestly
Sounds like a Samsung firmware bug.
Samsung will substitute smaller chipsets and components as needed during a production run.
So the base firmware may not be compatible with those devices unless Samsung recognizes the issue and modifies the instruction set for the firmware.
Congratulations, you're now a Samsung beta firmware tester...
its a hard life

Eventually Samsung may role out a fix.
If what I described above is the case Samsung is dependent on customers sending the phone in for repairs to physically see which chipsets or components were used in the build.
If it can be fixed by firmware they will likely roll out a patch if they get enough blow back.
If it can't be patched, replacing the mobo is their only solution.
If what I described is the case, sending it in under factory warranty is the only guarantee it will be fixed.
How to fix its? help me plzz
Try loading a early version of Device Care.
This is the original one loaded on my Note 10+.
It has 360° so if it loads firewall block this apk.
It may not load or behave erratically on a Note 20 or other models that aren't a 10+.
Not clue what will happen... are you feeling lucky today?
I encountered the same issue after upgrading my Note 20 ultra to android 12 via Odin flash. It's working and I also chose home_csc to retain my data. Trying to turn on Power saving keeps giving that same feedback, I wonder why. Also while typing this can anyone help me get mobile data toggle in my notification menu, I have all other icons except for the mobile data toggle
Edit: I've fixed the data and hotspot toggle using adb. The power saving mode is still unsolved
We need to change csc to vietnam

Question No Network Service after latest software update

Hello! I updated my phone to MIUI Global 13.0.7 Stable (SKHINXM) and suddenly my phone has no service. The sim card is fine and working on other phones like it was before the update. Really unable to fix this issue. If it helps, in the testing window the 'Mobile Radio Power' is toggled off and however many times I try to switch it on, it automatically switches off. Please help! Thanks

13.0.7 Stable (SKHINXM) is a stable beta.
Try to reset the phone or if your bootloader is unlocked flash with this tool

Will flashing the file lead to me losing all data? Apologies if it's a stupid question

Okay thank you! Will try it in a few days time once I am able to give it the time needed.
It is happening to me too, I'm on stock 13.0.4 SKHMIXM, bootloader locked, it happened in 13.0.3 too. Sometimes, I see I have no services, no data, no GPS. But WiFi works great, so if I'm in house I don't always see it, but it means I cannot receive call!!!
I tried to enable/disable sim/data/location/airplane/etc nothing works.
Only way to re-make it works is to reboot the phone, and after 2 or 3 weeks it will happen again, this is the price to pay to have cheap chinese phone...
Try booting into Android with Safe Mode. (and disable Airplane Mode if enabled)
Power + Volume Up > Safe Mode
Or try this:
Settings > Updater > Tap on the "13" several times, this will enable additional Updater-features. Download the latest package and install it.
My guess is that your update may have been corrupt.
Other than that.. Factory Reset or connecting phone to PC and flashing ROM using Fastboot & Mi Flash or Terminal.
I've 13.0.7 and everything's flawless.
So the Xiaomi service center told me that it is possibly a motherboard issue. How can a software update suddenly awaken a hardware issue?
So I had not unlocked my bootloader via my Mi account and it needs mobile data for the same and hence I am unable to flash it since my network is still unavailable even after a factory reset. Any other way I can flash my phone with an older version of MIUI or I will have to submit my phone to the service center?

Same issue i am facing after MIUI updation for 13.0.3.0 SJCINXM ... suddenly all networks are vanished ... if i do manual search for networks then i get a message 'Couldn't search for mobile networks' . Voice call is only possible if wifi is enabled.. This is really a horrible experience and i am unable to find out a way to get rid of this situation.. I am using Redmi 9 Prime handset .. Before this update everything was surperb and flawless.
It is still happening with the latest Android 13 and MIUI14, it's frustrating... sometimes when the phone switch wifi/lte/wifi/lte/etc when you go outside, the modem crashes, it internally bootloop and the phone becomes warm and can lose 25% battery in like 15 minutes. Only way is to reboot the phone.
I had a similar problem. Were you able to solve it?
