You can use x2 scaled maps (best option in Hi-Res devices) if you add &scale=2 at the end of the url, and replace the projection tag with:
MERCATORESFERICAx512

Hi, from France,
You can also do this with an Android file manager :

• (tested with OruxMaps free version installed with the free APK provided by the developer, not through Google Play)
• go into the folder oruxmaps\mapfiles
• rename onlinemapsource.xml in onlinemapsource.xml.OLD (for instance)
• rename onlinemapsource.xml.backup (liste complète) in onlinemapsource.xml .

one of the easiest solution available on net

it still works for oruxmaps v9.6
