My device overheated and now my touchscreen wont work when I open any

Hey there,

so this could be a hardware or software issue. how could it be a SW issue? The operating system of any machine (laptop, cellphone, etc.) manages its power settings (e.g. how to allocate power based on programs and apps, how the device is charged, how much power it should use when on sleep mode, when it should auto-shut down so the device won’t turn off during mid process, etc.).

For software issue, you can try the factory reset or make sure the firmware is up to date. I’m guessing this phone isn’t rooted or modified in some way you should tell us about? as for backing up everything, just google search: android backup pc program. look into this '''https://www.lg.com/us/support/product-he...

otherwise, all your data should be in your SD card right? and as for the logging into a bunch of accounts - yea I feel you, it is really annoying. however, no matter how you back up your device, you’ll always have to sign back into your apps and accounts. this is a security issue, so it will be either the device (LG) and/or the service (google, facebook, etc.) that will sign you out/make you re-enter your login info.

in case it’s a hardware issue, you have two options - get a new phone from your cellphone provider (hopefully you only got this phone recently or you have some awesome insurance) OR open it up to assess and rectify the issue.

from personal experience of having my cellphone heat up like this and when the issue is HW related, I found that there’s an issue with the battery — either it’s a defective battery (swollen, therefore pressing up against the motherboard) OR loose connections (both input and output directions, input being the USB external charging port and output being the power supplied from the battery to the motherboard). If you decide to check inside the device, go ahead and check all receptacle connections and make sure all parts are in their proper positions, even the slightest misalignment can put a stress on the board and mess up the board function.
