iPhone 7 lagging when unlocking

Wondering if any iPhone 7 users have experienced this issue whereby the phone will lag and become very sluggish when unlocking the phone. This issue arrived when I updated to iOS 14 and I didn’t have this problem in iOS 13. After unlocking , the animations will turn off and opening apps, scrolling through your apps will be really really laggy. After about 10 second when the unlock icon at the top of the screen disappears, then everything run as usual. Please respond if anyone have faced this issue before.

I’m facing the same issue on my iPhone 7 from iOS 13.

ive noticed one thing that this is bcz of auto brightness, why, just try to unlock your phone in dark when auto brightness won’t work and brightness will stay low, later try unlocking it by flashing any torch or flashlight on the sensor this will trigger the sensor to raise its brightness and hence our phones are lagging while unlocking ! I’ve been noticing this since a very long! I don’t know if it is a hardware issue or software bug!

My auto brightness is off and still have this problem, I have try everything and nothing helped. This problem is related to IOS14 cos my phone was working just fine without any freezing or lagging. But now I have this problem from upgrading to ios14 and all the way tonlast update to ios14.3. I have tried everything to turn off and on, resets, restoring and no restorning, nothing helped. Its like something heavy is working when phone is off screen, and when you woke up the phone there you have those 3-5 sec annoying lag.

I have the same issue and still waiting a official reply from Apple because it looks like its not based on battery life, RAM, available storage or any other similar things. It's really annoying and it happens really often. When I lock my screen to unlock again, sometimes it happens instantly. Like it was ok 1 seconds ago, what happened during 1 sec lock, to do this lag? It's frustrating and I can do nothing.

No it's not, just with this they push you to buy new iphone. Like before with slowing done old phones so people go and buy newer iphones, I think this problem is not fixed intentionally so you will be forced to go and buy newer one, but if they dont fix this bug, that is it. And ofc I will switch from iphone, apple watch, cancel all subscriptions and switch to android (probably samsung cos of their ecosystem), cos I don't want to buy another iphone like SE 2020 or 12 mini and after 3 years to have the same frustrating problem like now.

I remember when apple said ios is fluid and stable compared to android, but i have had android for over 10 years and ios for 5-6 years and sonetimes I use both at the same time, no mater how much people say that android is less stable and not fluid, I never had this problem with any of androids, but with ios theres always something, battery drain, lag, connectivity problems, etc. And they are making one software for one phone, android making one software for 10000 different phones, and doing much better job than ios... This problem will probably stay until we get ios 15 if iphone7 gets it.. but I'm not waiting ios15, probably few updates more if they dobt fix it just sell it and switch to android...

When you run programs that use navigation, this bug is most noticeable. The phone starts to dull terribly when unlocking. By the way, I have a second Iphone 7, it doesn't have such problems. And it keeps applications in memory too well. So there are different components inside? Apple, you have already released 3 firmware, but the problem remains, solve this issue. I don't want to buy a new phone, this one suits me.

I turned on „reduce motion“ and now the iPhone has become much faster during the lag. It does a short and light vibration though when the lag ends which I noticed already shortly after upgrading to iOS 14 even when it didn’t lag. This vibration might have something to do with the reason of the lag.

Also it looks like „reduce motion“ makes the phone generally faster as well.

When I turn reduce motion, its lagging even when phone is unlocked and when I'm using it, when I type and in half of message just freeze for 2 sec and when unfreeze phone type everything I typed when phone was frozen. When I turn reduce motion off phone is usable and just freezes and lag when unlock. And in use it's really rare to freeze or lag if reduce motion is off.
