[Peniche]

My phone works fine on LTE but when it goes to 3G it drops to the 1st bar and never goes up data, calls, sms stop working so when in this problem going to be fixed. I've seen alot of problems regarding signal is there any update that can fix this because inside of my home i have no service even if i have 1 or 2 bar on 3G mode, but when i go outside the LTE comes back on and work normally any help? Because everything indicates that thd phone is the problem
