Cannot install Google Contact app


Aug 22, 2016
I cannot reinstall Google Contacts on My Xiaomi Redmi Note 2 phone. The installation runs endlessly and I get error 504.
The phone is terribly hot under this endless process.
Phone already restarted , cleared all caches, but nothing helps.
Google play store often says "The application isn't installed", but after few minutes it works again.
How can I reinstall Google Play Store?
Google Contacts worked on my phone for more than 3 years, but after an unsussessful update I removed it.
Other apps can be installed without any problem.
