Blast from the past - square oil patch defect

[newone757]

its water damage. its from humidity/condensation or whatever and liquid gets under the screen. Eventually your touchscreen will stop working. As long as they water stickers check out you should be able to get a replacement at the store for free

this happened to me when i had my phone in my pocket on a hott day all day. If you play music through your phone in the bathroom while ur in the shower it could easily happen as well
