Alarm clock not ring on time

[schkr]

I've faced this problem many times before. But I waited new update solved this problem. But despite I updated my phone's software to 30.2.A.1.21, this problem has not solved yet. For instance I set up my alarm clock 6 a.m, alarm ring 6:04 a.m. I set STAMINA function when my battery level is lower than %15. I plug my phone charge before I go to bed, it is mean that my phone in charge all night and my battery never lower than %15. So I think this problem is not caused by STAMINA mode. Thank you for your interest.
Best regards!

I'm happy to hear that @schkr! I have also forwarded this internally for investigation so in either case we are looking in to it.

Hi @Georges98 and @Ozgarb, I can see that clearing data for the clock app and setting the time manually seems to have helped, could you try to see if it makes a difference for you as well? You can find instructions on how to do so in my previous post here.

Let me know if it worked for you guys as well!

Emir, I clear the clock data 
With manual mode alarm clock is fine but with auto mode alarm did not ring as it should

So , Its a bug ... 
I will choose manual mode for a while , but the company must fix that bug ....

I am happy to hear that it works with the solution I provided! In addition, I will make sure to forward the automatic setting feedback internally as user feedback.

Will SONY fix that problem ?

I understand your concern, @Georges98, but I'm afraid that I do not have any further information regarding this at this moment.

After the latest software update to marshmallow, the alarm goes off a few minutes later than usual, and the clock on my device falls behind until restarted.

does this happen when you are on safe mode?

since you recently updated your device you can try to perform software repair using Xperia Companion

Hey @SW6, I am sorry to hear that.

I posted a reply in this thread previously which seemed to help users experiencing the same behaviour, could you try to see if it helps in your case ass well? You can find the post by clicking here!

Hi @Emir...the clock doesn't seem to be lagging anymore, but the alarm still goes off a minute or 2 later...and if I snooze the alarm, the next snooze is also delayed by a few minutes.
