Hello, I bought my phone since 2 weeks, but I am experiencing 2 simple problems that are driving me crazy, the first one if that images take a while to load and show up in the gallery, be it screenshots, camera shots, bluetooth shared images, anything, secondly when browsing pdf documents on drive pdf, graphical glitches like rainbow bars are showing up (I noticed they disappear as soon as I screenshot or screenrecord), and I am sure its not an issue of the files themselves, because it happens with almost every pdf file I used and also they used to be browsed without any problems on my old phone.
