Freezing and won't respond to touch what can I do

Looks like the new update made some issue regarding your problem and here is how did i addressed the issue.

Just go back to the old version, sometimes infinix when they push the updates they don't reproduce the bugs which makes the phone don't function well and contains issue.

Sometimes when you put the phone into your pocket since it's mode don't function properly it will cause for touch to be spammed inside pocket ( length of the cloth between the phone and the body skin) so turn them off as they might cause our touch to respond or laggy like my Gboard in rare cases too

Sometimes notifications turns on your phone so instead of keeping the phone in the range you want just put the phone where camera faces your leg inside your pocket and never touch it

Factory reset your phone and never update it unless you asked inside Infinix official groups about the updates or you can visit carl care for further invastigating. Just ensure your still have the warranty not expired yet
