I have an LG K10 mobile phone. I was on Whatsapp and my phone gave an error saying that there is no enough space. Then, it restarted itself and gave "Unfortunately, system ui has stopped working" error. Now, I turn it on and have the same error. I can turn off the phone by removing the battery.
So, when open the phone I only see this error and cannot reach any options etc. I tried booting but there is not any option for clearing the cache.
I do not want to reset my phone so does anyone know how to save my data and begin to use my phone again? Thank you.
