Is there a free Android child lock for my son's phone?

My 8yo keeps sneaking his phone at night to watch videos. The basic Android parental controls aren’t cutting it since he finds workarounds. Any free app that can lock apps or set a bedtime?

Honestly Google Family Link is your best bet here — it’s free, built for exactly this, and lets you set a bedtime lockdown plus app limits right from your phone. The trick is making sure it’s properly set up as the device owner, otherwise yeah kids figure out the gaps pretty fast. My son pulled the same stunt until I enabled the “lock device at bedtime” feature and it just goes dark — no workarounds. :grinning_face_with_smiling_eyes:
