I want to change the read receipt image (blue ticks) in WhatsApp, I tried to rebuild apk with apk editor pro, but while installing , WhatsApp says,"something is wrong with your version of WhatsApp, please install latest version from play store". I want to replace the blue ticks image from WhatsApp so that is already installed, but I can't find where WhatsApp stores UI files.( As my phone is rooted, I can access system files too). Please tell me path where the image (of blue ticks) is stored in installed app. Reason to change it is I use my phone in monochrome, (using developer options), but in WhatsApp, both grey ticks and blue ticks look same in monochrome.
