security settings can affect compatibility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is Custom ROM good for old Android phones?<\/h3>\n\n\n\n<p>Yes, it often keeps old phones usable after official updates stop.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does flashing erase data?<\/h3>\n\n\n\n<p>Yes, flashing usually wipes all user data unless backup is taken.<\/p>\n\n\n\n<hr
