Since a while I have a bug in Whatsapp while drawing on a picture. When I use any color pencil, and I press anywhere on the screen to make a line or drawing, it automatically draws a line starting from a random angle messing up the picture.
I added screenshots:
1) I selected the pencil, now I want to underline the formula with Vx^2 = Vox^2 +2a etc.....
2) I start underlining from left and and you see the blue line coming from right under the screen before I can continue the line
Perform a force stop and clear the cache of WhatsApp. To do so, go to Settings > Applications > WhatsApp and choose Force stop. Next, go to Storage > Clear cache.
If this doesn't solve the problem, update WhatsApp to the latest version and try restarting your mobile phone.
As a last resort, perform a backup of your WhatsApp data, uninstall the application and reinstall it. Then restore your backup.
