Chosen Solution
I’ve found no brand specific info(contacted support as well), a local repair shop told me the same thing I already knew(defect most likely under the shields, removal is time-consuming), so it’s time to generalize. Anyone here, who knows what I should be prepared to learn to work with? The phone is Asus Rog Phone 3. My motherboard - https://ibb.co/GxCfb6Z

@mannga that will depend on how you take them off. Most of the EMI shields can be removed with a heat gun and after that you can actually resolder them. If you have to cut them off (yes sometimes a pair of good scissors works great, you will have to straighten them after but you can still resolder them as well. Some people even leave them off altogether. I guess it will depend on your technique as well as your skills. All the board and even so most of us cannot remove them, there are those that have specialized on the repair of those IC’s. Check the work of people like @refectio @imicrosoldering @thegsmsolution and many others on here. What you will need is some assistance with board level repair etc. and your challenge will be finding schematics etc. for the make and model of this phone.
Hello mannga! It would appear that the chips you have circled in your images are soldered directly onto the motherboard of the phone. This is very unfortunate as this means you cannot replace these chips without replacing the entire motherboard of the phone. As for removing the metal shields, that should not be very difficult as they would appear to only be held on with some strong adhesive. You can usually soften it with a hot blow dryer or heat gun and slowly work it off with a Uspudger or your fingers. You could also try dissolving it in some rubbing alcohol, but this method is not as preferred. If a repair shop has told you that the defect is under the shields, I am sorry to tell you that the likelihood of the ability to get it fixed is very low. At this rate, I would recommend that you go online or to a repair shop and ask that your whole motherboard be replaced as all of the chips on it are soldered directly to the motherboard. Hopefully this answered your question and will resolve your problem.
