Hello I got my HTC one 802w dual sim I checked for update and it said 4.2.2 was available so I did the update and now my play store is missing from the phone, As anyone had the same problem and if so how did you fix it. THANKS
Sounds like you have a dual sim HTC One which is meant for the Chinese market, which do not have Google Play Store. You initially must have had your handset come rooted and Play Store installed by you or someone else. When you updated your handset you lost your root and Play Store app.
