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

Sprint Galaxy S3 Android 4.4.2 on Ting MVNO (sprint network)
My wife's phone recently started going into factory mode (black box on main screen with yellow text showing data about the phone, I'd post a link but apparently I'm too new here. If you go to youtube and search galaxy s3 factory mode the first one that comes up from MrW0lf details it)
Additionally after a reboot she typically gets a notice that an android update was applied, which goes away when you click ok. I'm wondeing if the factory mode was triggered by a corrupt update that didn't install properly.
I haven't had a ton of time to research this, but this sounds like it is caused by a corrupt system directory (erf or something like that) the little I've seen the two big fixes seem to be factory reset and root (and then manually updating a system file from no to yes after every reboot to hide the factory data?). I did the factory reset last night using the settings > backup and reset > factory data reset (I know there are other methods, is there one that is more low-level and would hit the corrupt hidden system directory?). It didn't fix it, it still shows factory mode after rebooting and logging into the google account. And now after a reboot she gets the android update notice and when she clicks ok the 4G data connection disappears and won't come back (mobile data is still turned on in settings, if we turn it off and on, data still doesn't come back).
So I'm turning to the experts here, I've heard great things about XDA. What are my options here? I've never rooted a device before so I'm not confident with that as an option but if there are clear instructions I can try it. Money is tight (which is why we switched to ting) so I'm hoping for a free fix, and avoid buying a new/used device.
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

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.

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.
My neighbour has handed me her Samsung Galaxy Tab S model SM-T805 as she is unable to get the WiFi/Bluetooth enabled. It can be toggled to on but it remains grey. It appears to be up to date with Android 6.0.1
I have searched a lot for the solution and most suggestions have been to factory reset it. But after having done so, Samsung setup is still unable to enable WiFi. I went one step further by doing a factory reset/wipe data from Recovery but no dice.
What's the next step at this point?
edit: I also ran Device Initialization in Samsung's Smart Switch PC software to download and fully reset the tablet. Same issue still persists. Must be broken wifi hardware?

Downgrade the firmware first before condemning the hardware
Downgrade to lollipop.
It seems strange, but this can fix firmware errors causing these issues.
If it works after a downgrade it can then be updated as normal.

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

Try to reset the phone or if your bootloader is unlocked flash with this tool

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?
After applying the Android 12 OTA upgrade today, I can boot into the phone, however it looks like the System UI is constantly stuck instantly crashing upon launch, then reloading. the wallpaper is flickering on and off. I can take calls (and reboot the phone) just about, but I can't open any menu aside from the Power menu, or anything like that. Does anyone have any ideas how to resolve this? I'd try and enable adb mode or something like that but I can't beacuse I can't open any menu. I managed to boot into safe mode, but that had no effect and the problems are still happening.
Sometimes I can get it to briefly show the system icons, but it disappears too quickly for me to be able to do anything. If I was able to open the settings app, i'd be able to put it in USB file transfer mode to get my stuff of it, but I can't even do that.
Using the LG_UP tool, I can downgrade to the previous firmware, however I can't do anything as it then won't accept my encryption pin code. If flash the (broken) latest firmware back on, I can decrypt the phone, but I'm back where I was again where the system UI app just instantly crashes.
Right, so I think it's related to the lock screen. I was able to (somehow) manage to get it to the home screen from where I could open the settings app up and everything was fine, and was able to turn on USB file transfer mode. However as soon as the phone locked again, it stopped working. But it's very wierd.
You could try to do a factory reset. I think you have to start the device while holding one of the two power keys.

I think that would work, but i'm trying to avoid doing that as there's still stuff i'd like to get off of it. Maybe a future firmware update may fix this bug.
Most probably there will be no further update. Do you have a chance to take a look at the system protocol via "adb logcat" during the crash? Typically the notorious "com.android.systemui" is the culprit.
PS: In fact it does not matter, but is your device some 820 (G8) or the downgraded version 810 (G8s)?

It's the G8S. And I didn't have debug mode enabled, so adb doesn't work.

Yes, i'm pretty confident if I did a factory reset, it would work fine, but I really don't want to do that until i've got all my stuff off it.
i hear ya, understood, i just thought id fyi,
that the reset, as undesireable as it is. has appeared to fix the issue and phone, is as far as i can determine fully operational . the finger print reader, phone calls, and messaging all work
i just got the phone fixed less than an hour ago, after installing the 40a update a lil before noon or 2 hours ago lol
