(App) has stopped working I know there are already several posts about it (this one for example), but all the solution I found on this one, or one the Internet in general, didn't fix my problem.

My phone is a Wiko Fever, with the Android OS 5.1 (Lollipop) :

While launching, or performing a specific action in several apps, I have the error log :


  Unfortunately, (process) has stopped working.


I guess it's something like that, since my OS is not in english



As I said, I have this problem only on several applications :


The default SMS/MMS application (when opening a conversation)
I can still receive messages, but can't open them in a conversation.
Gmail (when opening an e-mail)
Steam (at launch)
Stack Exchange (when redirecting to a post, not in the menus)


I have tried almost everything said on the Internet :


Clearing App Cache
I rebooted my phone afterwards
Removing App Data
I rebooted my phone afterwards
Uninstalling and Reinstalling the app
Rebooting the phone in Recovery Mode then cleared phone cache




I fear the last resort which is the factory reset.

Do you have any idea what could be the cause, but mostly, the solution of this problem ? Thank you in advance !
I just found the cause of the problem :
It was due to the Android System Webview which was bugging and then couldn't display web UI on several applications.

I just had an update of it and now everything works fine ! 

One of the update's patch notes (translated from French, it may not be perfect) :


  Resolved crashes in applications using WebView in an application context
