Unfortunately, X application has stopped.

Hi guys, that's my first post in this forum. I bought my Xperia Z3 in november of 2014. From the first day i boought it, i have experienced reboots of the phone several times. I have seen the post where you talk about this so, i wont repeat this but it is a problem in my phone too. The problem i want to talk about is an error thats appear in my cellphone each time i go to sleep and have a heavy application running in my xperia. When i wake up, sometimes appear the next message: Unfortunately, Clock has stopped working (clock is an example, it has happened to me with clock, whatsapp, phone... etc). My question is, do i have a broken smartphone? Is this happening to someone more than me? How can i solve this problem, some idea?

Thanking you in advance.

Do you have an Antivirus or taskiller?

[Desniar]

Yes, i use Clean Master but dont use it every morning  and have it desactivated from prevent its action when i dont use it. However, i have just tried to boot my phone in safe mode and cant work with it. I mean, after booting it, it appears a screen for selecting the launcher (Xperia TM launcher or Simple Launcher), after selecting the Xperia TM Launcher appears the message: Unfortunately, Xperia TM Launcher has stopped and it happens everytime i select it so i cant get into the phone!!!! i will try removing all widgets but i think that it isnt a problem caused for the widgets.. 

P.S: Just confirmed, removing widgets does not solve the problem. I still cant booting it in safe mode because of the Xperia TM Launcher (it stops working each time i try to acces to it).

Try repairing your phone with Sony PC Companion and see if that helps.

I have experienced the same issues but I do not run a task killer because they are counter intuitive on Android; they cause more problems than solve. I have had at least two instances where all apps will crash unless I restart the phone. I have also had the phone reboot itself whilst I am not using it; sometimes in my pocket, others when lying on the desk and I see the reboot screen. Strange thing is the sim pin code unlock does not present itself unlike a real reboot. Why does this happen? What's wrong with Sony?

Hi Dcwt2010,

Such an issue can be hard to pin point, however in most cases where apps crash and a handset restarts, this is generally related to a faulty SIM card, faulty SD card or a third party application downloaded that has caused issues with the Android platform, unfortunately it can be only one application that causes all the issues on the device.

I suggest you check the basics, SIM, SD card and remove any third party apps that you had downloaded closer to the time it started playing up.

If this fails, a software repair is your best bet to remove any unwanted corruption.

I hope this helps.

OK guys, im back again. I used the tool of PC companion that restore the smartphone and its supposed to repair it. 2 days after using it and without installing any third party app the google now app crashed and stopped working so... what is the problem now? I have a regular nano-sim and a Kingston (32 GB and class 10) SD card. What can be producing this error now? i had to reboot the phone and the problem dissapeared but... to be honest, didnt expect that 2 days after using the repairing tool of PC companion.  I will notice you if this error (Unfortunately, X application has stopped) appear again.

Thank you.
