Iphone 4s white screen not responding

Question

Hi,
So basically my phone got a bit of water damage a couple months ago - it was working fine for about 2 months, then I switched it off one day and it wouldn't switch back on; I was getting a white screen with black edges, that slowly come in so the whole screen becomes black (this can take at least a day), then for love nor money, the phone won't switch on. Siri will occasionally talk to me if I hold down the home button, but that's the only response I get (and I have tried switching the phone off and blindly swiping the screen to properly switch it off that way, it doesn't work), and then after a few days (the longest I've had to wait is 2 weeks) the phone will suddenly switch back on. However, even once it's on, the screen flickers constantly and I can't use my camera as that just crashes the phone. I know it's all because of the water damage, and Apple won't be able to fix it without a hefty fee, but I was wondering if anyone else has had this problem and has any kind of solution?! I've tried literally everything I can think of, and while I try and not let my phone die at all, and have my powerbank on me all the time, sometimes it just happens!
Anyway, I don't think there's much anyone can do to help, but any suggestions are greatly appreciated!
Thanks

Sorry, but if you want a working phone again, there is nothing more you can do than to choose the Out-Of-Service-Warranty option to get the device replaced by a refurbished phone. The water damaged the phone too much, and the symptoms might even get worse, especially if the phone is still powered on.
Out-of-warranty repair service
If your repair isn’t covered by Apple’s One Year Limited Warranty, AppleCare+, or AppleCare Protection Plan, your iPhone might be eligible for out-of-warranty service. For example, liquid damage isn’t covered by warranty but might be eligible for out-of-warranty service. Some damage isn’t eligible at all, for example if your device has been broken into multiple pieces. See Apple’s Repair Terms and Conditions for complete details.
