Hello I'm using a Lenovo essential tab 7 buyed in 2017 it's been working good until 2023 June it started having minute black lines at corner I just leaved it , the lines started spreading throughout my tab and in 2024 March it suddenly gone off after I wake up from sleep, it's been 4or 5 months I did nothing,(it's just 1gb ram /8gb internal storage) I'm reading webtoon /manga and other comics stuff in that so suddenly pausing I've been reading more than 250+books that's the only reason I'm trying to fix it, and I dunno even if I fix it will my data will be erased, now if I use the power button normal black screen just comes some light
