Affected app version

org.fossify.phone version 1.10.0

Android 15 AP3A.240905.015.A2 / Xiomi HyperOS 2.0.211.0

Affected device model

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

1. Lock the phone (locked screen)
2. Get another phone to call you.

Expected behavior

1. When the phone receive a call while it is in the locked state, the accept or reject button does show and the call can be accepted or rejected

Actual behavior

1. When the phone rings the screen does not wake up and the accept or reject buttons do not appear - unable to pickup the call.
2. Manually unlocking the phone (while it's ringing) brings up the home screen and turns off the ringing sound and still no accept or reject buttons? but from the phone that initiated the call, it's still ringing?!?
3. If the phone is unlocked (home screen) and a call is received, the phone works as expected - the accept or reject buttons appear and the call can be accepted.

Screenshots/Screen recordings

No response

Additional information

The phone is not rooted
The issue appeared about 2 weeks ago
I have the following Fossify apps installed and set as default: Phone, Contacts, Messages, Calendar, Gallery, File Manager, Music Player.
Could it be a hardware issue? or an issue with a native system app?

Been using Fossify apps since version 1.0

This was already fixed in #165, but Xiaomi devices often break third-party apps. Please try:

• Disabling battery restrictions for Fossify Phone in system settings (see this comment)
• Enabling Show on Lock screen in Other permissions
• Solutions available on https://dontkillmyapp.com/xiaomi

Same issue on Honor 8x Android 10 using the latest version, gave access to everything, enabled overlay, disabled any possible battery optimizations according to don't kill my app website. Same scenario when you call when screen locked (lock in both screen on or off locked) there's no overlay displayed like OEM phone app to accept or reject the call, so you have to onlock the phone, bring down the notification panel, click on the incoming call notification, then it brings the incoming call screen which should be overlay on the phone and wake the device even if it's locked and screen is off. I have other applications for example xiaomi smart band and uses the overlay to show information and it works perfectly, also it adds another layer on top of lock screen to cover whole screen to show information.
Thanks, also there's another bug that I will refer to it in another request it's not related to this one.

Fossify Clock also displays full-screen alarms on the lock screen. Could you check if alarms are working properly in that app?

If full-screen alarms are working fine in that app, then there's definitely something that can be fixed in Fossify Phone. If not, it's a device-specific system restriction that can't be resolved in-app.

OK I'll check it out

• clock works
• removed overlay permission from phone app and gave it again fixed it
• also from notifications turned off gentle notification for phone app

Tried all the suggestions I could - (most were already applied) like: No battery restriction, show on locked screen, remove overlay permission from phone - restart - re-apply overlay permission - restart = still no change. But the 'donotkillmyapp' link refers to MIUI my phone uses HyperOS and some of the suggestions don't exist.

I don't use fossify clock, but native clock brings up overlay for an alarm.
Unlike 'ProAlit' when the phone rings on a locked screen, when I unlock the screen - I see the Home screen and the ringing sound stops but there is no notification on the screen nor if I pull down the screen? At that time the phone that initiated the call is still ringing even though the receiving phone is silent?
Tried a few different settings in the phone app

1. Disable proximity sensor during calls on/off = made no difference
2. Replace swiping at responding to incoming calls with clicking on/off = made no difference
3. Always display incoming calls on full screen on/off = made no difference when the phone is in locked screen, But when the phone is unlocked (home screen) when receiving a call and this setting is turned OFF the phone rings but just as with the locked screen the accept/reject buttons don't appear and the call can not be answered??

Sounds similar to #142. Strange if there is no notification even with the screen unlocked.

• Is the app allowed to send notifications?
• Do you see the call screen if you enable "Always display incoming calls on full screen" and keep the phone unlocked?

Either the system is preventing the app from launching or the app is crashing for some reason when a call arrives.

I don't use fossify clock, but native clock brings up overlay for an alarm.

Could you still install it just for testing? Preinstalled and popular apps are often whitelisted in the system.

I installed fossify clock and set an alarm = the alarm unlocked the screen and presented the option to snooze or stop
so it works fine for the clock.
I don't know if it is relevant, but looking trough the apps I found 5 phone related apps - they are as follow:

1. Phone - org.fossify.phone = Fossify phone app
2. Phone - com.google.android.dialer = Native phone app
3. Phone - com.android.incallui = ?
4. Phone Services - com.android.phone = ?
5. Phone and Messaging Storage - com.android.providers.telephony = ?

I did not yet 'factory reset' the phone, but I did re-installed HyperOS (about 2 weeks ago) and about a week ago there was an OS upgrade I was hoping that would fix the issue, when it did not that's when I posted on this forum

Thanks for testing! Will look into this more.
