Unable to install apps from unknown sources

Does anyone have the problem of being unable to install apps from sources other than the play store? For example, atm I'm trying to update 'Lucky Patcher' and the request for me to install the update which also shows the permissions the app is requesting but I can't actually press on the Install button. I can still press on the show all button and cancel button as well as the touchscreen keys at the bottom but just cant press on the Install button.
I was able to install unknown source apps before however, it just doesnt work now.
How do i fix this?

Is your unknown sources box still checked?

Yeah, double checked that. This has happened to me a few times now...
Edit: NVM! found the problem, was screen filter.

Just a heads up. No warez allowed on these forums...

Please explain how you did it. After a lot of searching on my own I found someone's advice to set the brightness to max and disable any screen dimming apps (which I have none installed, bought the device a month ago) and I still can't install apk files. Mind you the appropriate setting to allow unknown sources is set. The Install button just doesn't react exactly as you described. Everything else on the popup window is active (permissions and such). Please help!

Has anyone else encountered this problem?

I had this problem 2 months back. It turned out that the screen filter app that I was using was leading to this. I turned the app off and it worked
Sent from my Nexus 7 using xda app-developers app

I sat down and killed all the apps one by one. It turned out Battery Mix's battery bar (1px battery level indicator on the very top of the screen) was causing this behaviour. I will report this to the dev. So problem solved! :good:

Yeah, for my Nexus 4 the culprit was Juice Defender's brightness control. Disabled that and was able to install the apk I wanted to install. The developer does warn that this setting "might not work or cause problems".

Thank You All!!!!
Once again I was quickly able to solve my problem with a quick search on your forums!! Thank you all for giving such great advice. My problem with not being able to press the install button ended up being the "Twilight" App. Simple to temp disable/enable so not a big deal to me. I'm also going to let them know over at Twilight so hopefully a future update will solve this problem.

Thanks!!

Notification Problem

Hello Everybody
My P8 Lite Don't give me notification unless i open apps like whatsapp and viber and i marked show notification for them
any help please

You said, you've got the notification enabled for those apps, so there's only one thing that can cause problem, like this.
Go to your Settings > Power saving, then scroll down, and check the Protected apps menu.
Checked means it can run even if the screen is off.
Report back if it's worked for you, please.

Thx Man It Works For Me

I have whatsapp checked and I dont recieve the notifications, it is sudden.. I have to reset the phone.
It works fine and suddenly stops.
thks

same as @manuz89, if i reboot the phone it works but a few minutes later its bad again
i already have "normal" preset in battery settings, whatsapp its protected and all notification toggles are ON
im clearing cache right now and if it dont work i'll factory reset the phone

All other apps works properly, I think is a compatibility problem between Whatsapp and P8lite. Don't think factory reset will work

Before this phone, I had a S3 Mini, and that phone also had notification issues with WhatsApp...Maybe it's the app, not the phone

kitkat was fine, its the lollipop version with the problem.

But does this happen to everyone? Do you think someone will have an answer soon or we should just go back to kitkat.?
Thks

try changing your power mode to Normal, in case Smart is turning off a connection somewhere

Notification problem
I have the same problem - no notifications for whatsapp. All settings are correct. I.e. Notifications is allowed, power saving is normal, Whatsapp is protected. What else can I try? If I reset to factory will it delete all my photos etc?

No need factory reset. Anyway notifications of Viber(may be Whatsapp) do not work on this phone. You can easy resolve this bug with Light Flow - LED&Notifications. I use this method and work great!

unfortunately that app is not free. is there any other solutions. i did all those mentioned above including locking the app in the recent app tray. still, the problem persists. previously i used a xiaomi phone, it still had notifications although delayed for minutes

hi
just go to setting/screen lock& passwords/ screen lock style / and change it to default(magazine).
then you will see ( notification panel &notification turn on screen......) it will save the problem.
note : after you can change your lock screen picture and choose from your gallery.

Solved
Hello.
I had the same problem with whatsapp. After many research, i think i have found the solution:
Enable background data for Google Play Services app and allow notifications as well for this app.
(PS This solutions is mentioned also in the FAQ from whatsapp )))))) .. that simple
It worked for me.. try

Notification problem

yureka is frequently getting locked after new official update of cm12.1

My yureka is frequently getting locked after updating cm 12.1 .i cant do anything cz screen goes blank and then it get locked and wallpaper get changed to its default wallpaper and theme says it is customised. I traid safe mode but its not working. Any suggestion or tips ..?? Pls help....

[Solved]:
Usually it happens to everyone who upgraded to cyanogen 12.1 recently, even I had this problem and got the solution too.. Upgrading OS needs to take effect on GUI of the previous verson, so you have to reset your phone!
Do as follows:
> Take the data backup from your device,
>Go to settings, and reset the phone to the factory defaults!
>Done!

If this problem is solved by just factory resetting than why YU is ready to exchange the device for just this issue. I am also having the same problem and when I connected customer care the said that we will replace your device

Hey I have got a solution for this . Go to your device settings and then Privacy. Then go to privacy guard. There are three dots on upper right corner. CLICK ON THAT AND SELECT SHOW BUILT IN APPS. Now search for Google play services and hold on Google play services. Scroll downside and search for auto start and keep awake. Turn them off. But keep sure that (keep awake ) is enabled.
If it help you please thanks me.

I tried factory resetting but after few days it went back as it was . It doesn't help. Tjen on YouTube i found a solution its working .....
First i turn off double tap option that includs double tap to wake up and double tap to sleep then i removed all Google accounts and cyanogen account . And after that i cleared all the data of play store and play service .and then after rebooting i signed all my account back and my phone is working well till now....
And thanx for ur support guys....

Sync Issue Gmail

Hi. Is there any way to disable Doze mode fully? I am sick of refreshing gmail for important emails.

Hello... You can go here:
Settings > battery > 3 dot menu: optimization > tap on "non optimized" and select "all apps"
You can scroll down, tap on Gmail and choose "don't optimize"
I don't have any problem with Gmail notification though I let doze do its job.
Have you tried wiping Gmail data and cache or wipe, uninstall and reinstall to see if it works? You could also try to just wipe the whole cache from recovery...
Good luck...

Yes sir done that 100 times but it won't detach from doze, this is a known issue in nexus series and that's why I wanted to disable it completely. I am using Greenify instead already and it's serving me well.

Hey sir!
If you wrote the step you used trying to fix the issue, I wouldn't have advised it in the first place...
Anyway... Have you tried a search on Google? I found a command that disable doze completly. At least people report notifications working after that. It seems to work on OnePlus and Huawei devices, so it must be worth to try. If you haven't already...
Open a command prompt and issue:
adb shell dumpsys deviceidle disable
Not sure it survives a reboot.
Good luck... :good:

Wow... Nice. No need to credit me for this. But thanks. As I said, i just found the command with this simple Google search:
"Complete disable doze Android" without quote.
Try to reboot and check if the notification work yet. Or Google the command and see people reports. Hopefully the output you got from the command prompt confirms doze is really off for good. :good:

No Gmail Notification When in Sleep Mode

Hi guys,
I have a problem with Gmail notifications, they are not showing until I unlock my phone. I know it has to do with Doze, so I went to the Battery Optimization menu to try turning off optimization but Gmail app is not present in that list.
Is anyone else has problems with notifications? How do I turn off battery optimization for Gmail App on stock OnePlus 5?

Is the Gmail App available for you on the Battery Optimization list?

It isn't visible for me.

I concur, Gmail is not visible on the battery optimization list for me either. However, Inbox appears on the list.

Thanks for the replies.
Yeah, it seems that only apps installed from Google Play appear on Battery Optimization list.
Does anyone have a problem of missed Gmail notifications?

I get this as well both in my 3t and 5

I've disabled Doze in developer options and it seems the issue is solved, at least so far. With Greenify handling app hibernation I am not seeing much of a battery drain (and I have WiFi/LTE constantly on).

I've disabled Doze too and now the issue is gone. I have WiFi/LTE always on and I don't see any side effects for battery life, it is still good. So, that seems to be a solution.
Thanks, everybody!

Hello everyone. Ive been also having no Gmails after my OP5 screen is off after a few minutes. So I also went to battery optimization list to turn Gmail off from dozing. But it wasnt there. So I had to turn off Doze completely to get it to work. I did however figure out a way to keep Doze on and found a way to add Gmail to that list using a 3rd party app shortcut maker. But for me this didnt work. I still did not get Gmails despite it being exempt from the battery optimizations. But if someone wants to know how I was able to add it to that list let me know. Its not hard, and doesnt require root.

OK. What I did was use an app called QuickShortcutMaker to start to create a shortcut. Then in the search field I just typed "battery" and looked for the "Settings" section and there you should see "battery optimization". Select that, then select test shortcut. It should open the same "Battery optimization" as before, but will show many more apps then it does normally. Then you can go in there and change as many as you want. Let me know if you figure it out. Going by memory here. Hope that helps.

I have the same problem on OP5. Stock and modified ROMS. Developer options problem?

Just an update. I updated to 4.5.7 and got a Gmail update. Neither fixed it. Ive been in contact with the Oneplus bug hunters and I was told they would look into it. But for now the only way I get Gmails after the screens been off for about an hour is to keep Doze off completely, or wake up the screen. Also just updated to 4.5.8 and doubt anything was fixed as far as this issue goes.

If you have root, uninstall gmail with titanium backup and reinstall true Playstore , after that you probably have it visible in battery optimisation.

I was able to add Gmail to the not battery optimized list by using a shortcut creator that gave me the full list of apps. But this did not fix the issue where Gmails stop coming through after about 45 mins or so with the screen off. So I had to turn Doze all the way off.

I am experiencing same issue but with facebook messenger. Had no problem on 4.5.3 . Decided to update to 4.5.6 and no more notifications during sleep :/

Hi evryone, first post for me on this forum!
You are telling that turn off Doze solved the problem. Ok I want to do that!
I'm french and I don't find any Doze item in the developer menu. The only item which can correspond is "Mode somnolence" but it is already turn off!
Gmail notifications are very important for me. I'm very disappointed, it's a basic feature!!
Just one remark: I have 3 Google accounts, do you believe it can be a problem?

Hello!
And at me on OP5 with notifications from Gmail the same problems. I contacted the developers and provided them with the logs of working with this error. No answer so far. But, promised to understand. All the above solutions are not valid. It remains only to wait and hope.
