When I look at some photos in my gallery they either get disrupted by random colours or grey box appears on them, which when I swipe to next one and back, goes away. I can provide some screenshots of it,It happens only to few gallery files and they're all stored on phone storage.

Welcome to Android Central! Are these photos on Internal Storage or the SD card? If the latter, then the files or the card are probably corrupt. SD cards are more prone to file corruption than onboard memory.

In the post I said its on internal storage, and the corruption doesnt appears at first, but after the photo loads it just does this.

Oh sorry -- I was scanning for the term "internal storage," and not "phone storage" (which are the same thing, but I'm used to the former).

Does this happen in Safe Mode as well? https://support.t-mobile.com/docs/DOC-31115

I tried the safe mode and it happens there too, no change

First, make sure all of your important photos are backed up somewhere safe, like your computer hard drive or Google Photos in the cloud, in case something is about to fail on the phone. (It's also a good idea to make sure any other important data is backed up, besides photos.)

Next, try going to Settings>Apps, select the Gallery app, then Storage, then Clear Cache/Clear Data. Now open Gallery again and wait a few seconds for the database to rebuild. Does the problem persist?

If it still persists, then try using a different gallery app, like Google Photos or Focus.
