I don't have any memory on my cell phone. I can't even install the latest uodate. I have 3 apps and no pictures / videos on my phone. Does anyone know a solution or an app that will help me?
Either you expand your storage space with a memory card or you buy a new cell phone.
However, the memory card does not expand the internal memory, he / she still can't perform the update.
Or delete all unnecessary, garbage data. Or the app. You can then update, reset Andriod, etc. What you want for the update, reset would be good.
Check out your cloud
Buy an SD card if it has a slot
Clean up your memory with SDMaid, the app will also find everything, worked wonders on my old Huawei.
Now you have to expand the memory.
